Palo Alto Networks SD-WAN Engineer Sample Questions (Q51-Q56):NEW QUESTION # 51
An administrator has configured a Path Policy for "ERP_Traffic". The policy allows two public internet links, "ISP-A" and "ISP-B", both marked as "Active". The Path Quality Profile (SLA) requires a latency of less than 150ms. Currently, both ISP-A and ISP-B have a latency of 40ms, well within the SLA.
How does the Prisma SD-WAN ION determine which link to use for a new flow of "ERP_Traffic" when both active paths meet the SLA requirements?
  • A. It selects the path with the highest available bandwidth capacity.
  • B. It duplicates the packets across both paths (Packet Duplication) to ensure delivery.
  • C. It selects the path that appears first in the interface configuration list.
  • D. It selects the path with the lowest numerical latency (e.g., if ISP-A drops to 39ms).
Answer: A
Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN utilizes a sophisticated decision engine for Application-Based Path Selection that goes beyond simple failover. When configuring a Path Policy, the administrator defines "Active" paths and a "ath Quality Profile" (SLA).
SLA Compliance (The Filter): First, the system filters the available paths based on the Path Quality Profile. In this scenario, both ISP-A and ISP-B have 40ms latency against a 150ms threshold. Both are "green" or compliant paths.
Selection Criteria (The Tie-Breaker): When multiple paths are configured as "Active" and all meet the performance SLA, the ION device aims to optimize the overall user experience and network utilization. The default behavior for load balancing across healthy, compliant active paths is to select the path with the highest available bandwidth capacity.
By steering new flows to the link with the most "headroom" (available Mbps), the system prevents the saturation of a smaller link (e.g., a 20Mbps DSL line) while a larger link (e.g., 1Gbps Fiber) sits underutilized. This maximizes the aggregate throughput for the site. While latency is the qualifier, bandwidth availability is often the selector for compliant paths. Note that if the application was defined as "Real-Time" and configured for packet duplication, behavior would differ, but for standard traffic, capacity-based distribution is the standard active/active logic.

NEW QUESTION # 52
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?
  • A. The IPSec tunnel uses standard DPD (Dead Peer Detection) and the ION sends keepalives.
  • B. The CloudBlade automatically configures the ION to send Synthetic Probes (ICMP/HTTP) across the tunnel.
  • C. Prisma Access initiates the connection to the branch every 60 seconds.
  • D. The administrator must configure a continuous ping script on a branch PC.
Answer: A
Explanation:
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.

NEW QUESTION # 53
In the Prisma SD-WAN portal, the Application Health dashboard assigns a color-coded "Health Score" (Green, Yellow, Red) to applications.
Which three metrics are combined to calculate this composite AppX (Application Experience) score? (Choose three.)
  • A. Transaction Failure Rate
  • B. Jitter
  • C. Network Transfer Time (NTT)
  • D. Server Response Time (SRT)
  • E. Bandwidth Utilization
Answer: A,C,D
Explanation:
Comprehensive and Detailed Explanation
The AppX (Application Experience) score is a proprietary metric used by Prisma SD-WAN to provide a holistic view of user experience, rather than just network statistics. It is calculated based on three key components:
Transaction Failure Rate (A): The percentage of application transactions that failed (e.g., TCP resets, HTTP 500 errors). This indicates availability.
Network Transfer Time (B): The time taken for packets to traverse the network (WAN/LAN latency). This indicates network health.
Server Response Time (C): The time taken by the application server to respond to a request. This indicates backend performance.
Why not D or E?
Bandwidth Utilization (D) is a capacity metric, not a direct measure of quality. A link can be 90% full but still deliver packets quickly (good AppX), or 10% full but dropping packets (bad AppX).
Jitter (E) is a network-layer metric primarily relevant for UDP Real-Time media. While important, the high-level "AppX" score for general TCP apps focuses on the "Time-to-Glass" metrics (NTT/SRT) and success rates.

NEW QUESTION # 54
What is the number and structure of Prisma SD-WAN QoS queues supported per WAN interface?
  • A. 12 queues
    4 classes1
    3 application criteria within each class
  • B. 16 queues
    4 classes
    4 application criteria with each class
  • C. 8 queues
    2 classes
    4 application criteria within each class
  • D. 8 queues
    1 priority queue
    7 non-priority queues
Answer: B
Explanation:
Comprehensive and Detailed Explanation
The Prisma SD-WAN (ION) QoS engine utilizes a hierarchical queuing structure designed to provide granular control over application performance. Each WAN interface on an ION device supports a total of 16 QoS queues.
This 16-queue structure is derived from a matrix of 4 Classes (often referred to as Priority Classes) multiplied by 4 Application Criteria (Traffic Types).2
4 Priority Classes: The system defines four high-level business priority categories:3 Platinum (Highest priority)4 Gold Silver Bronze (Lowest priority/Best Effort)5
4 Application Criteria (Sub-queues): Within each of the four priority classes, the system further categorizes traffic into four specific application types to ensure proper handling (e.g., ensuring voice doesn't get stuck behind bulk data even within the same priority level):6 Real-Time Video Real-Time Audio Transactional Bulk7 Calculation: 4 Priority Classes × 4 Application Types = 16 Total Queues per interface. This structure allows the scheduler to ensure that a "latinum" voice call is prioritized over "latinum" bulk data, and both are prioritized over "Gold" traffic.

NEW QUESTION # 55
During the Zero Touch Provisioning (ZTP) process of a new ION device at a branch site, which interface ports are supported by default to request an IP address via DHCP and reach the Prisma SD-WAN controller for claiming?
  • A. Any LAN or WAN port on the device
  • B. The dedicated Controller port, or Port 1 / Internet 1 if a dedicated port is absent
  • C. Only the dedicated Controller port (if available)
  • D. Only the USB port via a cellular modem
Answer: B
Explanation:
Comprehensive and Detailed Explanation
For a successful Zero Touch Provisioning (ZTP) experience, the ION device must be able to obtain an IP address and reach the internet immediately upon boot-up.
According to Palo Alto Networks hardware guides, the Controller Port (often labeled specifically as "CONTROLLER" on models like the ION 3000/7000/9000) is pre-configured to act as a DHCP client by default. It is the preferred interface for the initial "call home" process.
However, for smaller desktop models (like the ION 1000/2000/1200 series) or scenarios where a dedicated management network is not available, the device firmware is also configured to attempt DHCP client requests on Port 1 (often labeled as Internet 1 or simply 1).
Connecting the ISP circuit to any random port (like Port 4 or a LAN port) will not work for ZTP because those interfaces are not pre-configured as DHCP clients in the factory default state. Therefore, the installer must ensure the internet uplink is connected to either the dedicated Controller port or Port 1/Internet 1 to ensure the device can resolve the controller FQDN and download its configuration.
