NCP-MCI-6.5 Nutanix Certified Professional - Multicloud Infrastructure (NCP-MCI) v6.5 exam Questions and Answers

According to section 4 of the exam blueprint guide1, one of the topics covered is AHV networking components and configuration settings. One of these components is Open vSwitch (OVS), which is a software switch that provides network connectivity between VMs and physical networks. OVS has two types of ports:

• Uplink ports: These are physical ports that connect to external networks or switches.
• Internal ports: These are virtual ports that connect to VMs or other internal networks.

To view the uplink state of all AHV nodes in the cluster, an administrator can use the manage_ovs command with the show_uplinks option. This command displays information such as port name, link state, speed, duplex mode, MTU size, bond mode, and bond status. However, this command only works on a single node. To run the command on all nodes in the cluster, an administrator can use the allssh command, which executes a command on all CVMs in parallel. Therefore, the correct command is:

allssh manage_ovs show_uplinks

The node is automatically re-imaged using the software currently running in the cluster. This is because Nutanix supports a feature called Auto Re-Image that allows adding nodes with different AOS versions to an existing cluster without manual intervention. The Auto Re-Image feature detects the AOS version mismatch and automatically downloads and installs the same AOS version as the cluster on the new node. This ensures that the cluster remains in a consistent state and avoids any compatibility issues.

network segmentation on Nutanix clusters refers to creating a separate network for service-specific communication and isolating different types of traffic over selected VLANs or physical interfaces.

According to section 6 of the exam blueprint guide1, one of the topics covered is VM placement options. When creating a new VM on an AHV cluster, there are two ways to determine its initial placement:

• Automatic placement: The Acropolis Dynamic Scheduler (ADS) selects a host that provides adequate resources for the VM’s configuration, such as CPU, memory, disk space, and network bandwidth. ADS also considers factors such as host load, power state, availability domains, and affinity rules.
• Manual placement: The administrator can specify a host or a host group where they want to place the VM.

The correct answer is C. Network latency.

The diagram shows a solution that uses synchronous replication between two remote protection domains, cluster site A and cluster site B. Synchronous replication is a feature that allows near-zero RPO (recovery point objective) by replicating data to the remote site before acknowledging writes to the local site. However, synchronous replication has some requirements and limitations that must be met for it to work properly. One of these requirements is that the network latency between the two sites must be less than or equal to 5 ms1. If the network latency is higher than 5 ms, the synchronous replication will fail and the protection policy will be suspended2.

Therefore, based on the diagram, the most likely cause of the issue is that the network latency between cluster site A and cluster site B is higher than 5 ms, which prevents the synchronous replication from working. To verify this, the administrator can use the “ncli cluster ping” command to measure the network latency between the two sites3. If the network latency is indeed higher than 5 ms, the administrator can either improve the network performance or switch to a different replication mode, such as near-synchronous or asynchronous.

According to the web search results, Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix environments12. One of the features of Prism Central is multi-cluster Single Sign On (SSO), which allows users to log in once and access multiple clusters without re-entering credentials3.

Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix environments1. Prism Central can be deployed in different configuration scenarios, depending on the network and security requirements of the environment. Some of the valid scenarios are:

• Environments use Network Address Translation (NAT): NAT is a method of mapping one IP address space to another by modifying network address information in IP datagram packet headers while they are in transit across a traffic routing device2. NAT can be used to enable communication between Prism Central and Prism Elements that are in different networks or subnets3. For example, Prism Central can be deployed in a public cloud and use NAT to access Prism Elements that are in a private data center3.
• Prism Elements and Prism Central are in different subnets: A subnet is a logical subdivision of an IP network that allows multiple networks to share a single physical network4. Prism Elements and Prism Central can be in different subnets as long as they can communicate with each other through routing or NAT3. For example, Prism Central can be deployed in a management subnet and access Prism Elements that are in different application subnets3.
• Environments do not have Internet access: Internet access is not required for the deployment of Prism Central, as long as the environment meets the prerequisites and considerations for installing or upgrading Prism Central. For example, Prism Central can be deployed in a dark site, which is an environment that does not have Internet access or has restricted Internet access. In this case, the administrator needs to manually enable microservices infrastructure and download the required software packages from another source.

This is because Nutanix uses a distributed storage fabric (DSF) that replicates data across multiple nodes and drives to ensure data resiliency. When a drive fails, the cluster detects the failure and initiates a data rebuild process to restore the replication factor (RF) of the affected containers. The data rebuild process does not affect the availability or performance of the VMs, as they can still access their data from other replicas on other nodes or drives. Therefore, there is no need to wait for 60 minutes, use a shared volume group, or trigger an HA event.

A bond is a logical interface that combines two or more physical interfaces on an AHV host. A bond provides high availability and load balancing for the network traffic of the host and its VMs. A bond can have different modes that determine how the traffic is distributed and how the bond handles failures of the physical interfaces. The most common bond modes are active-backup, active-active, and LACP1.

Nutanix recommends including at least two physical interfaces in every bond to ensure high availability and redundancy. If one of the physical interfaces fails or is disconnected, the other interface can take over the traffic without affecting the connectivity of the host or its VMs. Having at least two physical interfaces in a bond also allows for maintenance operations such as firmware upgrades or cable replacements without downtime2.

Nutanix does not recommend including NIC models from different vendors in the same bond, as this may cause compatibility issues or performance degradation. Nutanix also does not recommend using only one physical interface in a bond, as this provides no redundancy or load balancing benefits3.

The correct answer is D. Fewer than 30 I/Os and less than 1000 bytes per day of network traffic for the past 21 days.

A zombie VM is a type of inactive VM that is powered on but does very little activity. A zombie VM wastes host resources such as CPU, memory, disk, and network that could be used by other VMs. A zombie VM can be identified by using the VM Profile feature in Prism Central. The VM Profile feature analyzes the resource utilization of each VM and assigns it a profile based on its efficiency and impact on other VMs. The profiles are as follows1:

• Efficient: The VM is well-provisioned and has optimal resource utilization.
• Over-provisioned: The VM has more resources than it needs and has low resource utilization.
• Constrained: The VM has less resources than it needs and has high resource utilization.
• Inactive: The VM has no resource utilization and is idle or powered off.
• Bully: The VM has high resource utilization and causes contention for other VMs.

A zombie VM is a subtype of an inactive VM that meets the following criteria2:

• The VM is powered on for the past 21 days.
• The VM does fewer than 30 read or write I/Os (total) per day for the past 21 days.
• The VM receives or transfers fewer than 1000 bytes per day of network traffic for the past 21 days.

To identify a zombie VM, the administrator can use Prism Central to view the VM Profile dashboard and filter by profile type. The dashboard shows the number of VMs in each profile type, as well as their resource consumption and efficiency score. The administrator can also drill down into each VM to see its detailed metrics and recommendations for optimization.

According to the Nutanix Prism Central Guide, role-based access control (RBAC) in Prism Central allows you to create custom roles and assign them to users or groups based on the categories of the entities they need to manage1. Categories are key-value pairs that you can assign to entities such as VMs, hosts, clusters, images, etc. to group them logically2. For example, you can create a category key called “OS” and assign values such as “Linux” or “Windows” to different VMs based on their operating system.

In the exhibit, the Linux Admin role has been created with the following settings:

• The role has the “VM Admin” permission, which allows the user to perform all actions on VMs3.
• The role has been assigned to the admin1 user.
• The role has been scoped to the entities that have the category key “OS” and the value “Linux”.

However, the admin1 user does not have access to all Linux VMs in the environment. This means that some of the Linux VMs do not have the proper category assigned to them. To grant the proper access, the administrator should add the category key “OS” and the value “Linux” to each Linux VM that needs to be managed by the Linux Admin role. This can be done either individually or in bulk through Prism Central4. Once the categories are added, the admin1 user will be able to see and manage all Linux VMs in the environment.

Data locality is the capability of storing VM data on the node where the VM is running and ensuring that the read I/O does not have to traverse the network. Data locality is a unique feature of Nutanix that provides high performance and low latency for VMs by minimizing network traffic and crosstalk. Data locality works by writing one copy of the data local to the VM and the other copy (or copies) on other nodes. When a VM migrates to another node, Nutanix also moves its data to the new node and serves all I/O requests locally. Data locality also adapts to changing workloads and access patterns by dynamically moving data to where it is needed most1.

According to the Nutanix Community1, users can authenticate using their Active Directory credentials when Active Directory support is enabled for Prism Central. To enable Active Directory support, you need to configure Role Mapping12, which defines how Active Directory groups map to Prism Central roles.

https://next.nutanix.com/ncm-intelligent-operations-formerly-prism-pro-ultimate-26/configuring-authentication-38051

Active-Active is a bond mode that allows all uplinks in the bond to be used simultaneously for traffic transmission and reception. This bond mode provides load balancing and increased bandwidth for the AHV host and its VMs. Active-Active bond mode uses a hashing algorithm based on source MAC addresses to distribute traffic across different uplinks in the bond. Each individual VM NIC uses only a single bond member interface at a time, but multiple VM NICs are spread across different bond member interfaces. As a result, it is possible for a Nutanix AHV node with two 10 Gb interfaces to use up to 20 Gbps of network throughput, while individual VMs have a maximum throughput of 10 Gbps6.

Therefore, if an administrator needs to optimize for maximum single VM throughput, they should select Active-Active bond mode for their AHV cluster. This bond mode can be configured using Prism Element UI or manage-ovs commands on each AHV host7. No additional configuration is required on the upstream switch side, as long as the switches are interconnected physically or virtually and both uplinks trunk the same VLANs8.

LCM (Life Cycle Manager) is a feature that allows Nutanix administrators to perform one-click firmware and software upgrades for Nutanix clusters and components. LCM fetches inventory and update information from a pre-configured URL that contains the latest versions of firmware and software packages. However, upgrading Nutanix AOS does not automatically update the fetch URL. To update the fetch URL, the administrator needs to update the LCM framework. The LCM framework is the core component of LCM that provides the logic and functionality for inventory, download, and upgrade operations1.

To upgrade the LCM framework, the administrator needs to perform an LCM inventory. An LCM inventory is a process that scans the cluster and its components for their current firmware and software versions and compares them with the available versions from the fetch URL. If there is a newer version of the LCM framework available, it will be shown as an update option under Cluster Software Component in the Available Updates page. The administrator can then select and apply the LCM framework update to upgrade it to the latest version2.

The administrator can perform an LCM inventory using Prism Element or Prism Central. The steps are as follows3:

• In Prism Element, go to the Network Configuration page and click Life Cycle Management.
• In Prism Central, go to the Services page and click Life Cycle Management.
• Click Inventory in the toolbar and select Perform Inventory from the drop-down menu.
• Wait for the inventory process to complete and check for any available updates.

Answer: A. VM-VM anti-Affinity policy

A VM-VM anti-Affinity policy is a rule that ensures that two or more VMs don’t run on the same AHV host. It’s useful when an application provides HA and an AHV host can’t be an application’s single point of failure1. In this case, the SQL cluster VMs should have a VM-VM anti-Affinity policy configured to prevent them from running on the same host and causing an outage if that host fails. A VM-VM anti-Affinity policy can be created using the aCLI commands2. The other options are not relevant for this scenario.

References: 1: Affinity Policies - Nutanix Support & Insights 2: Affinity Policies Help | Nutanix Community

Configure VM-Host affinity for the nodes that meet the application’s GPU requirement. This is because VM-Host affinity allows the administrator to specify which nodes a VM can run on or must not run on1. By creating a VM-Host affinity rule that binds the application VM to the three nodes that have the physical GPU, the administrator can ensure that the VM will always run on a node that meets its requirement, regardless of any HA or migration events. This also allows the other nodes in the cluster to host other VMs without any restrictions.

Nutanix supports two types of deduplication: post-process and inline. Post-process deduplication runs periodically on a schedule and can be enabled on any cluster. Inline deduplication runs in real time before data is written to disk and can be enabled only on all-flash clusters.

Therefore, by checking the type of storage and the type of deduplication, you can determine if you can enable inline deduplication on a storage container or not.

 Nutanix inline deduplication is a feature that reduces the stored size and avoids duplicate data on a storage container1. It is recommended only on some specific scenarios, such as when using Nutanix Files or virtual desktop infrastructure (VDI) workloads12.

when you create a custom alert policy, you can choose between two types of thresholds: Static Threshold and Behavioral Anomaly. Static Threshold allows you to set a fixed value for the metric that triggers the alert. Behavioral Anomaly allows you to use machine learning to detect abnormal behavior based on historical data.

If you select Behavioral Anomaly as the threshold type, you cannot set a warning level for the alert. You can only set a critical level that indicates how much deviation from normal behavior is considered an anomaly3. Therefore, the Alert warning if field is greyed out when you select Behavioral Anomaly.

Flow Networking is a feature that enables software-defined networking for AHV clusters. It allows users to create and manage virtual private clouds (VPCs), subnets, and network services such as NAT, DHCP, routing, and VPN. Flow Networking also supports service insertion and chaining, which enables integration with third-party network functions such as firewalls and load balancers. Flow Networking is built on top of the microservices infrastructure (MSP) in Prism Central, which provides the platform for running various Nutanix services such as Calm, Karbon, and Objects. Therefore, to enable Flow Networking, the MSP must be enabled first on Prism Central1. The MSP can be enabled from the Prism Central settings page or from the command line interface (CLI) of the Prism Central VM2. Enabling the MSP will also enable Flow Microsegmentation, which is another feature that provides network security and visibility for AHV clusters.

NTP service needs to be configured to ensure logs, alerts and information is consistent across clusters that are located in different countries. NTP stands for Network Time Protocol and it is used to synchronize the clocks of all the nodes in a cluster1. This helps to maintain accurate timestamps for logs, alerts and other information that are generated by Nutanix clusters1.

According to the Dell Unity: Data Reduction Technical White Paper1, snapshots and clones on Dell Unity use the Copy-on-Write (CoW) algorithm to maximize efficiency and effectiveness. CoW is a technique that defers the copying of data until it is modified. This means that snapshots and clones only consume space when changes are made to the source or the clone, respectively. CoW also preserves the original data in case of a rollback or recovery operation.

The correct answer is C. The VLAN was not created on the upstream switches.

A VLAN (virtual local area network) is a logical segmentation of a physical network that allows devices on the same VLAN to communicate with each other, regardless of their physical location. A VLAN also isolates the devices on different VLANs from each other, unless there is a router or a layer 3 switch that can route traffic between VLANs. To create a VLAN, the administrator needs to configure the network devices that are involved in the VLAN, such as switches, routers, and hosts. The administrator also needs to assign a unique VLAN ID to each VLAN, which is a number between 1 and 4094 that identifies the VLAN1.

In Nutanix AHV, the administrator can create a Nutanix managed network with a specific VLAN ID for guest VMs. This network can be assigned to VM NICs using Prism Element or Prism Central. However, creating a Nutanix managed network does not automatically create the VLAN on the upstream switches that connect the AHV hosts. The administrator needs to manually configure the upstream switches to allow the VLAN traffic on the ports that connect to the AHV hosts. The administrator also needs to ensure that the upstream switches are interconnected physically or virtually and can forward traffic between different VLANs if needed2.

Therefore, if an administrator has created a Nutanix managed network with a VLAN ID of 512 and notices that the VMs on that network can only communicate with other VMs on the same host, but not with VMs on different hosts in the cluster, the most likely cause of this issue is that the VLAN was not created on the upstream switches. This means that the switches are dropping or blocking the traffic with VLAN ID 512 and preventing it from reaching other hosts or VMs. To resolve this issue, the administrator should create the VLAN on the upstream switches and allow it on the ports that connect to the AHV hosts3.

data size for flash mode exceeds 25% of the SSD capacity could cause the performance issues. Flash mode is a feature that allows vDisks to be pinned to SSDs for faster access, but it has a limit of 25% of the SSD capacity per node. If this limit is exceeded, some vDisks may be evicted from flash mode and cause disk latency2.

This is because there is no GUI method to unregister a cluster from Prism Central, so the process requires SSH access to the PC VM as well as to a CVM of the cluster2. The unregistration process involves getting the UUID of the cluster from the CVM and then using that to trigger de-registration from PC command line2. The unregistration process also involves cleaning up any associated metadata and configuration on both PC and PE2. Therefore, the administrator needs to use a Host SSH session to perform this task.

Reclaiming Licenses (Including License Renewal)

You can reclaim and optionally re-apply licenses for nodes in your clusters:

• You must reclaim licenses when you plan to destroy a cluster. First reclaim the licenses, then destroy the cluster. You do not need to reclaim Starter licenses. These licenses are automatically applied whenever you create a cluster, including after you have destroyed a cluster.
• Return licenses to your inventory when you remove one or more nodes from a cluster. Also, if you move nodes from one cluster to another, first reclaim the licenses, move the nodes, then re-apply the licenses.
• You can reclaim licenses for nodes in your clusters in cases where you want to make modifications or downgrade licenses. For example, applying an Ultimate license to all nodes in a cluster where some nodes are currently licensed as Pro and some nodes are licensed as Ultimate. You might also want to transition nodes from Ultimate to Pro licensing.
• You must reclaim licenses when you renew licenses. First reclaim the expired licenses, then apply new licenses.

CloudInit is a package that contains utilities for early initialization of cloud instances. It allows you to customize virtual machines provided by a cloud vendor by modifying the generic OS configuration on boot. You can use CloudInit to set the OS hostname, add custom users, add keys, run custom scripts, and more2. CloudInit is supported by most major Linux and FreeBSD operating systems and works across different cloud platforms3. Sysprep is a tool for Windows operating systems that prepares an installation for cloning, auditing, and customer delivery4.

References: 1: Replacing Nodes in Nutanix Cluster - Nutanix Support & Insights 2: Customize a Linux VM with cloud-init in Azure - Azure Virtual Machines 3: Cloud-Init - The standard for customising cloud instances 4: Sysprep (Generalize) a Windows installation

According to the Nutanix Support & Insights website1, you can configure alert emails through Prism Central by enabling or disabling customer email notification for each alert. You can also modify or create custom alert policies for different entities and clusters23.

According to the web search results, three storage optimizations that should be set on a dedicated storage container for a VDI solution with persistent desktops are compression, deduplication and erasure coding. Compression is a technique that reduces the size of data by removing redundant information. Deduplication is a technique that eliminates duplicate copies of data blocks and stores only unique blocks. Erasure coding is a technique that increases usable capacity by reducing the replication factor of data blocks and using parity information instead7. These three optimizations can improve performance and save storage space for VDI workloads, especially during a node failure event when data needs to be rebuilt from parity information8. The administrator can enable these optimizations by using Prism Element web console or ncli command-line interface9.

The output in the exhibit indicates that the node's network interfaces (eth0-eth3) are bonded together using LACP (Link Aggregation Control Protocol) with 'balance-tcp' as the bonding mode and LACP speed set to 'fast'. For LACP to function correctly, the switch ports to which the node is connected must also be configured to support LACP. If the ports on the upstream switch are not configured for LACP, the bond will not be able to establish properly, and the node will not communicate effectively on the network, making it undiscoverable when attempting to expand the cluster.

The absence of an operational LACP configuration could prevent the new node from joining the existing cluster as the node's network interfaces would not be able to pass traffic correctly. This can be verified by checking the switch configuration to ensure that the ports are set to participate in an LACP bond.

The other options, such as a firewall blocking discovery traffic (Option A) or the node being on different VLANs (Option C), are possible causes for a node not being discovered, but given the specific command output provided, the most likely cause is related to the switch port configuration for LACP. Option D, regarding completing LACP configuration after cluster expansion, is not correct because LACP needs to be operational for the node to communicate with the cluster during the expansion process.

Proper LACP configuration is critical for network communication in a Nutanix AHV cluster, and this is covered in detail in the Nutanix AHV and Networking documentation. It outlines the steps for configuring network bonds and LACP on both the AHV hosts and the connecting network infrastructure.

API Explorer page will launch when an administrator presses the letter A on the keyboard after logging into Prism Element. This is one of the keyboard shortcuts that Prism Element provides for accessibility and ease of use1. API Explorer is a tool that allows users to explore and test Nutanix REST APIs within Prism Element1.

Categories are key-value pairs that can be used to tag entities such as VMs, images, networks, and projects in Prism Central. Categories can be used to create dynamic groups of entities based on their attributes, and assign roles and permissions to those groups3. In this case, a category such as OS=Linux can be used to group all Linux VMs and grant access rights to the Linux administration team.

The correct answer is D. VM Storage Controller Bandwidth.

VM Storage Controller Bandwidth is a metric that measures the amount of data that a VM is reading and writing to the storage fabric. The storage fabric is the network of storage controllers (CVMs) that provide distributed and fault-tolerant storage services to the VMs on the Nutanix cluster. The VM Storage Controller Bandwidth metric shows the read and write bandwidth in megabytes per second (MBps) for each VM. The higher the bandwidth, the more data the VM is transferring to and from the storage fabric1.

The administrator can use Prism Central to view the VM Storage Controller Bandwidth metric for each VM in a chart or a widget. The administrator can also use Prism Central to view other metrics related to the VM’s storage performance, such as VM Storage Controller IOPS, VM Storage Controller Latency, and VM Disk Usage2.

According to the web search results, the cluster redundancy factor (RF) determines how many copies of the cluster metadata and configuration data are stored on different nodes. By default, the cluster RF is 2, which means that there are three copies of the Zookeeper and Cassandra data on the cluster. If the cluster RF is increased to 3, then there will be five copies of the Zookeeper and Cassandra data on the cluster12. This means that the Zookeeper component can tolerate two failures, as it can still operate with a quorum of three nodes out of five3.

However, the container replication factor (RF) determines how many copies of the VM data and oplog are stored on different nodes. The container RF can be set independently for each container, and it can be different from the cluster RF. For example, a container can have RF 2 even if the cluster has RF 34. In this case, the container will only have two copies of the VM data and oplog on the cluster, regardless of the cluster RF. This means that the Extent Groups component can only tolerate one failure, as it needs at least one copy of the VM data and oplog to be available5.

Therefore, if the administrator increases the cluster RF to 3, but does not modify the containers, then the new values in the data resiliency dashboard will be Zookeeper = 2 and Extent Groups = 1.

Answer: D. Load the Virtual SCSI pass-through controller.

The error message shown in the image indicates that Windows 10 setup cannot find any drives to install the OS. This is because the Nutanix AHV hypervisor uses a virtual SCSI pass-through controller to present disks to the VMs, and Windows 10 does not have a built-in driver for this device. Therefore, the administrator needs to load the Nutanix VirtIO driver for the virtual SCSI pass-through controller during the OS installation process. The Nutanix VirtIO driver package contains various drivers that are specifically used by Windows VMs hosted in the Nutanix environment to enhance their stability and performance1. The administrator can download the latest Nutanix VirtIO driver package from the VirtIO downloads page of the Nutanix support portal. The administrator can then follow these steps to load the driver and install the OS2:

• On the Windows 10 setup screen, click Load driver.
• Insert a USB drive or mount an ISO image that contains the Nutanix VirtIO driver package.
• Browse to the location of the driver package and select the folder that matches the OS architecture (32-bit or 64-bit).
• Select the vioscsi.inf file and click Next.
• Wait for the driver to load and then click Refresh.
• Select the disk where you want to install Windows 10 and click Next.

According to the Nutanix Prism Central Guide, Prism Central allows you to apply storage policies on a per VM basis using Category, so that the VM uses the storage configuration defined in the storage policy. Using a storage policy, you can manage parameters of VMs, such as encryption, type of or lack of data compression, and IOPS or Throughput throttling values to be applied to the entities.

A storage policy can be associated with a VM. A storage policy is a set of rules that define how data objects are stored and protected. It specifies the characteristics of storage, data protection, and data placement for virtual disks that are assigned to a VM. Subnets, catalogs, and categories are not associated with storage policies.https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2022_6:mul-cluster-storage-policy-summary-view-pc-r.html
