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

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.

Configuring a webhook allows the company to receive real-time notifications when Prisma Access changes its egress IP addresses, ensuring that policy rules are updated automatically. Downloading a client certificate is necessary for authentication to the Egress IP API, allowing secure API access for retrieving updated IP addresses. These actions ensure that security policies remain effective without manual intervention.

By usingsecurity checks under posture settingsinStrata Cloud Manager (SCM), the senior engineer can enforcepolicy compliance standardsbyautomatically denyingany security policy that does notalign with best practices. This ensures that junior engineers can create policies while preventing configurations that might introduce security gaps. This proactive approacheliminates manual oversightand enforces compliance at the time of policy creation, reducing risk and ensuring consistent security enforcement.

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.

TheBGP peernot coming up despite anestablished IPSec tunnelindicates a potentialBGP configuration issue.

Secret– IfMD5 authenticationis configured for BGP, both Prisma Access and theCustomer Premises Equipment (CPE)must have thesame secret (authentication key). A mismatch will prevent BGP from establishing a session.

Peer AS Number– TheAutonomous System (AS) numberof the BGP peer must match what is expected on both sides of the connection. If the AS number is incorrect, the BGP session will fail to establish.

By verifying these elements, the engineer can troubleshoot and establish a successfulBGP peering sessionover theIPSec tunnel.

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 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.

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.

Palo Alto Networks documentation explicitly states that the"Preview Changes"functionality within the Strata Cloud Manager (SCM) push dialogue allows engineers to review a detailed summary of all modifications that will be applied to the Prisma Access configuration before committing the changes. This is the primary and most reliable method to ensure only the intended changes are deployed.

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

A. Review the SCM portal for blue circular indicators next to each configuration menu item and ensure only the intended areas of configuration have this indicator.While blue circular indicators might signify unsaved changes within a specific configuration section, they do not provide a comprehensive, consolidated view ofallpending changes across different policy areas. This method is insufficient for verifying the entirety of the intended modifications.

B. Compare the candidate configuration and the most recent version under "Config Version Snapshots".While comparing configuration snapshots is a valuable method for understanding historical changes and potentially identifying unintended deviationsaftera push, it does not provide a real-time preview of thependingchanges before they are applied during the current modification session

C. Select the most recent job under Operations > Push Status to view the pending changes that would apply to Prisma Access.The "Push Status" section primarily displays the status anddetails ofcompletedorin-progresspush operations. It does not offer a preview of the changesbeforea push is initiated.

Therefore, the "Preview Changes" feature within the push dialogue is the documented and recommended method for an engineer to verify that only the intended changes will be applied when modifying Prisma Access policy configuration in Strata Cloud Manager (SCM).

TheStrata Logging Serviceallowslog replay, which enables resending logs that were not successfully forwarded to an external syslog server due to disruptions. By configuring areplay profilewith the affected time range and associating it with thesyslog server profile, Prisma Access will resend the missing logs, ensuring that all relevant data is restored in the external logging system. This approach is the most efficient and automated way to recover missing logs.

InPrisma Access, security policies are evaluated based on theirconfiguration scope. If the engineer configured aSecurity policyunder theRemote Networks scope, but traffic from the branch locations is instead matching aSecurity policy under the Prisma Access configuration scope, the intended policy will not take effect. This happens becausePrisma Access evaluates security rules based on the highest-level applicable configuration first, which can override more specific Remote Networks policies.

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.
