Palo Alto Networks SD-WAN Engineer 認定 SD-WAN-Engineer 試験問題 (Q69-Q74):

質問 # 69
An ION 3000 device at a remote branch has suffered a critical hardware failure and must be replaced via the RMA process. The administrator has received the replacement unit.
What is the correct procedure to transfer the configuration and license from the defective unit to the replacement unit to ensure minimal downtime and retention of historical data?

正解：B

解説：
Comprehensive and Detailed Explanation
The RMA replacement process in Prisma SD-WAN is designed to be seamless, leveraging the decoupling of logical configuration from physical hardware.
Replace Device Workflow: The administrator should use the "Replace Device" (or RMA) function within the portal. This workflow allows you to select the "Defective" device (old serial) and the "Replacement" device (new serial).
Configuration Transfer: Once executed, the system automatically binds the existing Device Shell (which contains all interface configs, routing policies, and site associations) to the new hardware's serial number. The new device, once connected to the internet, will "call home," identify itself, and download the exact configuration of the previous unit.
License Transfer: While the configuration moves automatically, the Support License transfer typically requires a specific step in the Customer Support Portal (CSP) or happens automatically if processed as a formal RMA order. Options A and D are incorrect because they involve manual reconfiguration, which is unnecessary and error-prone. Option C is incorrect as the ION platform relies on cloud-based config management, not local USB backups for hardware swaps.


質問 # 70
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.)

正解：A、B、C

解説：
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.


質問 # 71
Which statement is valid when integrating Prisma SD-WAN with Prisma Access remote networks?

正解：D

解説：
Comprehensive and Detailed Explanation
When deploying Prisma Access for Remote Networks (connecting branch offices), the licensing and throughput model is based on aggregate bandwidth allocated to specific compute locations (regions).
Bandwidth Allocation (Option D): Administrators must purchase and allocate a specific amount of bandwidth (e.g., 500 Mbps, 1 Gbps) to a Prisma Access "Compute Location" (e.g., US West, Europe Central). This allocated bandwidth is then shared as a pool among all the branch sites (Remote Networks) that onboard and terminate their IPSec tunnels at that specific location. The system does not allocate bandwidth on a strict per-site basis but rather enforces the limit on the aggregate throughput of the compute node itself.
Policy Enforcement (Option A): Security policies for Prisma Access are enforced in the cloud (at the Prisma Access Service Processing Node), not pushed down to the branch ION devices for local enforcement. The ION device handles local segmentation (ZBFW) and traffic steering, but the "Remote Network" security stack resides in the cloud.
Path Usage (Option C): Prisma SD-WAN is designed to utilize Active/Active paths. When a branch has multiple internet circuits connected to Prisma Access, the CloudBlade and ION automatically build tunnels on all compatible paths and can load-balance traffic across them based on application performance (SLA), rather than defaulting to a strict Active/Standby model for internet traffic.


質問 # 72
When troubleshooting an issue at a site that is running on two cellular links from two carriers, the operations team shared some evidence shown in the graph below:
(SNR Graph showing Carrier-1 in blue dropping to near 0 dB and Carrier-2 in green staying relatively stable between 4.5 dB and 6.5 dB)

For the time duration shown in the graph, what are two inferences about the site's traffic that can be made? (Choose two.)

正解：A、D

解説：
Comprehensive and Detailed Explanation at least 150 to 250 words each from Palo Alto Networks SD-WAN Engineer documents:
In Prisma SD-WAN, the Signal-to-Noise Ratio (SNR) is a critical metric used to monitor the health and performance of cellular WAN interfaces. SNR measures the strength of the desired signal relative to the background noise level; higher values indicate a cleaner signal, while lower values suggest that noise is overwhelming the signal, typically leading to increased packet loss, high latency, and reduced throughput.
Analyzing the provided graph, Carrier-1 (blue line) shows a severe drop in SNR, plummeting from approximately 4.5 dB to nearly 0.3 dB between 15:00 and 23:00. An SNR value this low is indicative of a failing or highly unstable link that cannot reliably sustain data traffic, directly supporting Inference A-that Carrier-1 experienced significant performance degradation. In contrast, Carrier-2 (green line) maintains a much higher and more consistent SNR throughout the same period.
Prisma SD-WAN's AppFabric uses application-based path selection and SLA monitoring to ensure the best possible user experience. When the system detects that a primary path (like Carrier-1) has degraded below acceptable thresholds-often triggered by high loss or latency resulting from poor signal quality-it will dynamically steer application flows to an alternative healthy path. Therefore, Inference D is correct: because Carrier-1's quality became untenable while Carrier-2 remained stable, the ION device would have likely initiated a path switchover to move traffic from the degraded Carrier-1 to the healthier Carrier-2.


質問 # 73
Two branch sites, "Branch-A" and "Branch-B", are both behind active NAT devices (Source NAT) on their local internet circuits.
What requirement must be met for these two branches to successfully establish a direct Dynamic VPN (ION- to-ION) tunnel over the internet?

正解：B

解説：
Comprehensive and Detailed Explanation
Prisma SD-WAN supports Dynamic VPNs (Branch-to-Branch) even when both endpoints are behind Source NAT (e.g., typical broadband connections).
To achieve this, the ION devices utilize standard NAT Traversal techniques, specifically leveraging STUN (Session Traversal Utilities for NAT).
* Discovery: Each ION communicates with the Cloud Controller (which acts as a STUN server/signaling broker). Through this communication, the controller observes the public IP and Port that the ION's traffic is coming from (the post-NAT address).
* Signaling: The controller shares this public reachability information with the peer ION.
* Hole Punching: The IONs then attempt to initiate connections to each other's discovered public IP
/Port. This "UDP Hole Punching" allows them to establish a direct IPSec tunnel through the NAT devices without requiring static 1:1 NAT mapping or manual port forwarding on the provider routers, enabling mesh connectivity in commodity internet environments.
