C1000-142 IBM Cloud Advocate v2 Questions and Answers

Explanation

Cloud native refers less to where an application resides and more to how it is built and deployed. Most organizations using containerized microservices also use a container orchestration platform, such as kubernetes, to automate container deployment and management at scale. Cloud native applications are built to operate only in the cloud. Developers design cloud native applications to be scalable, platform agnostic, and comprised of microservices.

Correct Answer : Hypervisor is a small software layer that enables multiple operating systems to run alongside each other. Hypervisor separates the VMs logically, assigning each its own slice of underlying computing power, memory, and storage. There are 2 types of Hypervisor : Type 1 & Type 2. Hosted is another name given to a Type 2 hypervisor. Type 2 Hypervisors : Run as an application in a host operating system, rather than in place of an operating system ⦿ Create a virtual machine and install a guest operating system on it ⦿ Assign physical resources to a virtual machine and set the amount of processor cores and memory it can use ⦿ Known as “hosted” ⦿ Mostly used for end-user virtualization, less frequently used, higher latency ⦿ Some examples are Oracle VirtualBox and VMware Workstation In-Correct Answers : Virtual Machine : A virtual machine is a virtual representation of physical computer, that behaves like an actual computer. Single Tenant : Sigle tenant means, used by single organization only. Bare metal server are single-tenant physical servers that are dedicated to a single customer. Bare metal servers fulfill the demanding needs of high-performance computing (HPC) and data intense applications. Use cases : Bare metal server are suitable for CPU and I/O intensive workloads.

Correct Answer: If you want to use encryption at rest, you must use VMware vSAN Enterprise edition with a key management server (KMS) like KMIP for VMware on IBM Cloud.

Resiliency means - Quick recovery from unexpected failure.

IBM Cloud Paks are: Portable and can run anywhere: The portability of hybrid cloud solutions built with IBM Cloud Paks means that they are built to run on any hybrid cloud environment.

Application virtualization: Application virtualization runs application software without installing it directly on the user’s OS. This differs from complete desktop virtualization (mentioned above) because only the application runs in a virtual environment—the OS on the end user’s device runs as usual. There are three types of application virtualization:

Local application virtualization: The entire application runs on the endpoint device but runs in a runtime environment instead of on the native hardware.

Application streaming: The application lives on a server which sends small components of the software to run on the end user's device when needed.

Server-based application virtualization : The application runs entirely on a server that sends only its user interface to the client device.

IBM® API Connect is an integrated API management offering, where all of the steps in the API lifecycle, and the actions that surround it, are performed within the offering. The steps of the API lifecycle include creating, running, managing, and securing APIs.

Explanation

The IT equipment within a data center consists of three main elements necessary for a computing environment to function: Compute: The memory and processing power needed to run applications that are usually supplied by enterprise-grade servers. Storage: Data centers include primary and backup storage devices. They may be hard disk or even tape drives, but best-in-class facilities typically feature all-flash arrays. Networking: They contain a broad array of networking equipment, ranging from routers and switches to controllers and firewalls. In addition to the IT equipment it contains, every data center houses that equipment’s support infrastructure, including the following: Environmental controls: Sensors monitor the airflow, humidity, and temperature in the facility at all times, with systems in place to guarantee that temperature and humidity remain within hardware manufacturers' specified ranges. Server racks: Most data center equipment is housed in specially designed racks or in purpose-built cabinets or shelving. Power supplies: Most data centers employ battery-based backup power systems able to compensate for short-term power outages and larger generators that can supply power in case longer commercial power grid outages occur. Cabling and cable management systems: An enterprise data center may contain hundreds of miles of fiber optic cable. Systems and equipment to keep that cabling orderly and accessible are a must.

By using the IBM Cloud® Security and Compliance Center, you can significantly decrease the likelihood of a misconfiguration-related security issue by setting guardrails around the way that your resources can be configured. With the Configuration Governance component of the Security and Compliance Center, you are able to define rules and templates that can help to standardize your organizations resource configuration. When you create a rule and enable enforcement, you can apply it to your entire enterprise, account, or a subset of your resources by limiting your scope to a resource group. Then, when a rule is in place, a user in your account is unable to provision a resource or set a configuration that violates the rule. In some situations, resource configurations require multiple API calls to set. In these cases, you must also define a template in order for the resource to be configured. With templates, you can define your preferred values, or customized defaults, on properties that are used to configure an IBM Cloud resource. By creating templates that users in your accounts can regularly review and reference, you set guidelines for teams to follow. After you attach a template to a scope, your customized defaults are applied by target services to ensure that your selections override the IBM-defined values each time that a target resource is created.

Cloud adoption is a strategy used by organizations to improve customer service and reduce costs while increasing efficiencies. Benefits of Cloud Adoption: - Scalability - Cost-Effectiveness - Security - Backup and Recovery - Accelerated Adoption A value of cloud adoption is the collaboration it allows between teams across widespread geographical regions, including international locations.

Direct area storage, also known as direct-attached storage (DAS), is as the name implies. DAS is a storage device which directly connected to your computer or server, if often connected to a single machine only. Some examples of direct attached storage are floppy disks, optical disc, compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDD), flash drives and solid-state drives (SSD). DAS is often connected with single computing machine only so sharing capabilities are limited and poor. Block storage is highly available and resilient and will often include data encryption at rest and in transit. Block storage, is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Block storage suitable for low latency workloads where consistently high speeds required. File Storage associated with Network Attached Storage (NAS) technology. File Storage organizes files in a hierarchy of named directories. The ability for File Storage to be mounted to multiple compute nodes at a time make it an ideal solution for common storage requirements. Object Storage enable you to store and access unstructured data anywhere in the world with a self-service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high-speed file transfer capabilities, cross-region offerings and integrated services. Use cases : Backup and recovery, Data archiving, Cloud-native application, AI and big data analytics.

Correct Answer: Block storage stores data by breaking it into evenly sized blocks, which is written to disk. The data stored is highly available because each block is stored multiple times across different disks. Block storage is used for computing situations where users require fast, efficient, and reliable data storage Block storage can be deployed on a Virtual Private Cloud (VPC) or classic environments.

You can use security groups to enact a set of IP filter rules that define how to handle incoming and outgoing traffic to both the public and private interfaces your instance. Use security groups when you order a virtual server. That way, your server is protected when it is first provisioned. Other Scenarios with solutions listed below : 1. Security scenario: Customers want granular control over traffic at an instance level (apart from network-level firewalls). However, at the same time, the costs of a shared hardware firewall can add up quickly if you need to protect multiple servers in different data centers. Solution: You do not incur extra charges for using security groups. You can use security groups for all virtual servers that need protection in any of our global data centers. 2. Security scenario: You want to avoid configuring firewall rules on each server separately. Instead, you want an easily manageable firewall solution that spans servers in different global data centers. Solution: Define N security groups for N different types of servers in your cloud workload. Manage all rules for a security group in one place. Manage the security group associations with the virtual servers.

Correct Answer: AWS Lambda, Google Cloud Functions, Microsoft Azure Functions are automation services of AWS, GCP and Microsoft. Server-less computing is a cloud computing execution model that provisions computing resources on demand and offloads all responsibility for common infrastructure management tasks. They are auto scalable so Its can handle extremely active traffic periods.

Explanation

Cloud native is an architectural style where the application is typically one that is designed to run on a specific platform. In many cases, these applications can also be moved around to different cloud platforms — so they are also cloud agnostic.
