SSE-Engineer Palo Alto Networks Security Service Edge Engineer Questions and Answers

When multitenancy is enabled in Prisma Access (Managed by Panorama), a key characteristic is the isolation of resources between tenants. Palo Alto Networks documentation emphasizes that each tenant operates within its own logically separate Prisma Access environment. This includes dedicated compute instances, ensuring that the performance and security of one tenant are not impacted by the activities of another.

Let's analyze why the other options are incorrect based on official documentation:

A. Service connection licenses will be assigned only to the first tenant, and these service connections can be shared with the other tenants. This statement is incorrect. In a multitenant Prisma Access deployment, licenses are typically managed and allocated per tenant. While the underlying infrastructure might be shared by Palo Alto Networks, the logical resources and often the licensing are segmented for each tenant. Sharing service connections across completely separate tenants would violate the principle of tenant isolation.  

B. A single tenant cannot consist solely of mobile users or solely of remote networks. This statement is incorrect. Prisma Access multitenancy allows for flexibility in how tenants are configured. A tenant can be designed to exclusively serve mobile users, exclusively connect remote networks, or a combination of both, depending on the organizational structure and requirements.  

D. There is flexibility to manage different tenants using separate Panoramas, which allows for better organization and management of the multiple tenants. While it is possible to have multiple Panorama instances managing different parts of a large infrastructure, when discussing multitenancy within a single Prisma Access instance (as implied by the question "enabling multitenancy in Prisma Access (Managed by Panorama))", all configured tenants are managed by that single Panorama instance. Managing different tenants with separate Panoramas is a different architectural consideration, not a defining characteristic of enabling multitenancy within one Prisma Access deployment managed by a specific Panorama.

Therefore, the defining characteristic of Prisma Access multitenancy (Managed by Panorama) is the allocation of dedicated Prisma Access instances and compute resources for each tenant, ensuring logical separation and resource isolation

TheCloud Dynamic User Groupcapability inCloud Identity Engineenables the creation ofSecurity policiesthat useEntra ID (formerly Azure AD) attributesfor user identification. This allows PrismaAccess to dynamically applyuser-based security rulesbased onreal-time Entra ID attributes, ensuring that access policies adapt to user changes such asgroup membership, device compliance, or role updates.

When the "Overlapping Subnets" checkbox is selected during the Remote Network onboarding process in Prisma Access, the deployment enables Private Application access using Prisma Access for Users(ZTNA or Private Access). This feature is designed to handle scenarios where multiple sites use the same IP subnet by leveraging NAT (Network Address Translation) and segmentation to avoid conflicts.

Since overlapping subnets can create routing challenges for direct remote network-to-remote network communication, Prisma Access does not support Remote Network-to-Remote Network or Mobile User communication in this case. Private application access is supported as Prisma Access correctly routes requests based on application-layer intelligence rather than IP-based routing.

In amultitenant deployment, access control must be configured at theChild Tenantlevel to ensure that security administrators have full control over Security policyonly within their assigned tenantwhile restricting access to other tenants. By selectingPrisma Access & NGFW Configuration, the assigned users gain full administrative accessonly for security policy managementwithin the designated tenant, aligning with RBAC best practices for controlled access inPrisma Access Managed by Strata Cloud Manager.

After configuringdomain-based split tunnelingforzoom.us, the expected behavior can be confirmed by checking therouting table on the client machine. If split tunneling is correctly configured, the traffic forzoom.usshould be routedoutsidethe GlobalProtect VPN tunnel, while other traffic follows the tunnel path. Reviewing the routing table ensures thatonly the intended traffic is excluded from the tunnel, confirming that the split tunnel configuration is working as expected.

Updating theCloud Services plugininPrisma Accessdoes not disrupt existing traffic flows because the upgrade process is designed to beseamless and transparent. Prisma Access ensures high availability by maintainingactive sessions and policieswhile applying the update in the background. This allows ongoing connections to continue without interruptions, minimizing impact on user experience.

When network routers appear multiple times with different IP addresses in IoT Security, it is likely because they have multiple interfaces with separate IPs. Merging these entries into a single device with multiple interfaces ensures that the system correctly identifies each router as a unique entity while maintaining visibility across all its interfaces. This approach prevents unnecessary duplicates, improves asset management, and enhances security monitoring.

InPrisma Access, configuring anotification profileallows engineers to receive alerts when IPSec tunnels experience downtime or instability. By definingspecific conditions for remote network IPSec tunnels, the notification profile ensures that the engineer is proactively informed abouttunnel failures, flapping, or degraded performance. This approach enables timely troubleshooting and minimizes disruptions for users relying on the IPSec tunnels.

User mapping learned from sources other thangateway authenticationcan cause intermittent access issues if it conflicts with the expected user identity used in HIP-based policies. If the firewall is associatingthe user with an outdated or incorrect mapping, traffic may not match the intended security policies, leading todenials by the Catch-All Deny rule.

If thefirewall loses user mapping due to missed HIP report checks, the user may temporarily lose access to policies that require a validHost Information Profile (HIP)match. When the VPN connection is refreshed, the HIP check is re-initiated, restoring access until the issue repeats.

When onboarding toPrisma Access, usingDedicated IP addresseshelps address concerns about the time required to updateSaaS-allowed IP lists. Withdedicated egress IPs, the customer receivesfixed, predictable IP addressesthat do not change dynamically. This eliminates the need to frequently updateSaaS providers' allowlists, ensuring seamless access to cloud applications without interruptions due to IP address changes.

Service connections enable secure connectivity between Prisma Access and on-premises data centers, allowing mobile users and branch locations to access internal applications. They facilitate seamless integration of internal networks with Prisma Access while maintaining security policies. Colo-Connect provides a dedicated and optimized pathway for traffic between Prisma Access and data centers, ensuring stable performance and reduced latency over the internet. Both components together support secure and efficient data center connectivity while aligning with the customer's access control and filtering requirements.

When configuringRemote Browser Isolation (RBI)inPrisma Access (Managed by Strata Cloud Manager)for mobile users, aURL access management profilemust be created with thesite access action set to "Isolate". This profile is thenapplied to a Security policyto enforce isolation for specific URLs. This ensures thatweb traffic to designated high-risk or untrusted sitesisredirected to a remote, secure browser instance, protecting endpoints from potential web-based threats.
