33. Frage
When using the CloudBlade to integrate Prisma SD-WAN with Prisma Access, how does the system ensure that the IPSec tunnels between the branch ION and the Prisma Access Security Processing Node (SPN) are kept alive during periods of no user traffic?
Antwort: C
Begründung:
Comprehensive and Detailed Explanation
The stability of VPN tunnels in the Prisma SD-WAN + Prisma Access integration relies on standard IPSec mechanisms.
Dead Peer Detection (DPD): The CloudBlade configuration automatically enables DPD on the IPSec tunnels it provisions.
Mechanism: DPD is a standard keepalive mechanism where the ION device sends periodic "R-U-THERE" messages to the Prisma Access gateway (and vice versa). If no acknowledgment is received after a specific count/timer, the ION marks the tunnel as down and attempts to re-key or switch to a backup path.
Synthetic Probes (B): While Synthetic Probes (part of ADEM or Path Quality monitoring) can be configured to measure latency/loss, the fundamental mechanism that keeps the IPSec security association (SA) active and detects link failure is DPD, not an application-layer probe.
34. Frage
Which condition, when configured within a performance policy, is a trigger for generating an incident related to application performance or path degradation?
Antwort: A
Begründung:
In Prisma SD-WAN, Performance Policies are the primary mechanism used to define the expected quality of experience for specific applications. Unlike traditional monitoring that relies solely on "up/down" interface states, Prisma SD-WAN focuses on the actual health of the application path. An incident is triggered when the system detects a violation of defined service-level agreement (SLA) thresholds, such as excessive latency, jitter, or packet loss, even if the physical link remains active.
When an administrator configures a performance policy, they set specific bounds for these metrics. For example, a VoIP application might have an SLA requiring latency below 150ms and packet loss below 1%. If the ION device detects that the current path (e.g., a broadband circuit) exceeds these limits, it generates a performance incident. This incident serves two purposes: first, it alerts the administrator to the degradation; second, it triggers the Path Selection engine to proactively steer the application traffic to a more suitable
"Backup" or "Available" path that currently meets the SLA requirements.
Options B, C, and D represent system-level or network-level events that generate different types of alerts or incidents (System or Network incidents), but they are not the triggers defined within a Performance Policy.
Performance policies are specifically concerned with the application's perceived performance across the fabric. By focusing on SLA violations rather than just physical link status, Prisma SD-WAN ensures that business-critical applications remain functional even during "brownout" conditions where a circuit is technically "up" but performing poorly.
35. Frage
In which modes can a Prisma SD-WAN branch be deployed?
Antwort: C
Begründung:
Comprehensive and Detailed Explanation
Prisma SD-WAN (formerly CloudGenix) defines three distinct Operational Modes for a branch site, which determine how the ION device processes traffic and interacts with the network.
* Analytics Mode (Monitor): In this mode, the ION device is typically deployed inline or in a
"promiscuous" monitor state to gain visibility into network traffic without actively enforcing path selection policies.1 It "learns" applications, bandwidth usage, and network characteristics (auditing) but does not steer traffic or block flows.2 This is often used during Proof of Concepts (POVs) or the initial
"burn-in" phase of a deployment to generate reports without risking network disruption.
* Control Mode: This is the full production state. In Control Mode, the ION device actively enforces Path Policies, QoS Policies, and Security Policies. It builds Secure Fabric VPN tunnels, steers traffic based on application SLAs (e.g., sending voice over MPLS and bulk data over Broadband), and handles failover events.3 This is the required mode for a fully functional SD-WAN site.
* Disabled Mode: This mode effectively shuts down the site's SD-WAN functionality from the controller's perspective. It is an administrative state used when a site is being decommissioned, provisioned but not yet live, or isolated for troubleshooting. In this state, the device does not participate in the fabric.
36. Frage
A network engineer is troubleshooting a user complaint regarding "slow application performance" for an internal web application. While viewing the Flow Browser in the Prisma SD-WAN portal, the engineer notices that the Server Response Time (SRT) is consistently high (over 500ms), while the Network Transfer Time (NTT) and Round Trip Time (RTT) are low (under 50ms).
What does this data indicate about the root cause of the issue?
Antwort: C
Begründung:
Comprehensive and Detailed Explanation
The Flow Browser and App Response Time metrics in Prisma SD-WAN are critical tools for isolating the fault domain-determining whether a problem lies in the "Network" or the "Application."
* Network Transfer Time (NTT) / Round Trip Time (RTT): These metrics measure the time it takes for packets to traverse the network (WAN/LAN) and for acknowledgments to return. A low NTT (e.g.,
<50ms) confirms that the network pipes (SD-WAN overlay, Underlay circuits) are healthy and transporting packets quickly.
* Server Response Time (SRT): This metric specifically measures the time between the server receiving a request and the server sending the first byte of the response. It essentially measures the "processing time" of the backend server.
In the scenario described, the network metrics (NTT/RTT) are excellent, effectively ruling out WAN congestion, packet loss, or latency (Option A and C). However, the Server Response Time (SRT) is very high (500ms). This signature is a definitive indicator that the network delivered the request instantly, but the application server took a long time to process it. This points the troubleshooting effort toward the server infrastructure (e.g., a slow SQL query, an overloaded web server, or lack of compute resources) rather than the SD-WAN environment.
37. Frage
When configuring SASE connectivity with easy onboarding at a branch, which two options must be selected?
(Choose two.)
Antwort: C,D
Begründung:
Prisma SD-WAN simplifies the integration with Prisma Access through a feature known as "CloudBlades," specifically the Prisma Access for Networks CloudBlade. The "easy onboarding" workflow is designed to automate the complex task of establishing secure tunnels between Branch ION devices and the SASE security processing nodes (SPNs).
When an administrator initiates this process, the system abstracts the manual configuration of IKE and IPSec parameters. Instead of manually defining an IPSec Crypto Profile or an IKE Profile (which are automatically handled by the CloudBlade orchestration), the user must specify where the traffic is going and which physical resources will handle the connection. The Prisma Access Primary Location (Option B) is a mandatory selection because it determines the geographical region and specific compute instance within the Prisma Access cloud that will serve as the primary security gateway for that branch.
Furthermore, the IPSec Termination Node (Option D) must be selected to define the specific endpoint within the Prisma Access infrastructure where the ION device's tunnels will terminate. This selection ensures that the Controller can properly orchestrate the site-to-site VPN tunnels, ensuring that the branch traffic is correctly routed to the SASE fabric for security inspection. By selecting these two options, the CloudBlade can automatically negotiate the rest of the tunnel parameters, significantly reducing the potential for human error and accelerating the deployment of a Secure Access Service Edge (SASE) architecture across multiple branch locations.
