質問 # 14
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：C、D
解説：
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 # 15
An administrator wants to configure a Path Policy that routes all "Guest Wi-Fi" traffic directly to the internet using the local broadband interface, bypassing all VPN tunnels.
Which Service & DC Group setting should be selected in the policy rule to achieve this "Direct Internet Access" (DIA) behavior?
正解：D
解説：
Comprehensive and Detailed Explanation
In Prisma SD-WAN Path Policies, the Service & DC Group (Destination) field determines where the traffic is sent.
* Direct: This is the specific keyword/object used to instruct the ION to route traffic directly out to the local WAN interface (Local Breakout) towards the Internet, without encapsulation in a VPN tunnel.
This is the correct setting for Guest Wi-Fi, SaaS applications (like Office 365), or any public web browsing that does not need to be backhauled.
* Standard VPN / Default-Cluster: These options direct traffic into an IPSec overlay tunnel destined for a Data Center or another ION. Selecting these would "backhaul" the guest traffic, which contradicts the requirement for DIA.
When "Direct" is selected, the ION uses its available "Internet" category links. The policy can further specify which internet link to use (e.g., "Use Broadband, avoid LTE") via the path preference list, but the Destination type must be "Direct".
質問 # 16
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：C
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.
質問 # 17
Return traffic for an application from the branch is being dropped on the branch ION. Application traffic arrives via SD-WAN internet overlay at the branch, and path policy for the application at the branch has the following settings:
Active = MPLS Overlay
Backup = Prisma Access on internet
Which branch configuration is the probable cause of this behavior?
正解：C
解説：
In Prisma SD-WAN, path selection and traffic symmetry are governed by the Path Policy and the available physical/virtual circuits at a site. The scenario describes a situation where return traffic is dropped on the branch ION after arriving via an Internet overlay. To understand why, we must analyze the "Active" and
"Backup" paths defined in the policy.
The policy specifies Active = MPLS Overlay and Backup = Prisma Access on internet. In a healthy environment, the ION device expects to send and receive traffic based on these defined paths. If the site actually has two internet circuits and no MPLS circuit (Option C), a critical mismatch occurs. Because there is no MPLS circuit available to satisfy the "Active" path, the device will fall back to the "Backup" path for initiated traffic.
However, the core issue here relates to how Prisma SD-WAN handles asymmetric routing and session state.
If traffic arrives at the branch via an "Internet Overlay" path that is not explicitly defined or allowed as a valid path for that specific application in the Path Policy, the ION device's flow integrity checks may drop the packets. Specifically, if the ION is configured with only Internet circuits but the policy is looking for an MPLS overlay that doesn't exist, the device may fail to correctly associate the return packets with the session state if the paths are perceived as "unbound" or "invalid" per the policy. This behavior is a security feature designed to ensure that traffic only traverses paths that meet the administrator's defined performance and security criteria. Without an MPLS circuit present, the policy cannot be fully realized, leading to potential drops for traffic arriving on paths not intended for that specific application flow.
質問 # 18
Which implementation allows Prisma SD-WAN to improve application performance for organizations facing inconsistent user experiences across branch locations, especially due to varying device types and network conditions, by using Layer 4 and Layer 7 optimization to boost throughput?
正解：A
解説：
Prisma SD-WAN addresses inconsistent application performance through Application Acceleration, which encompasses a suite of features designed to mitigate the effects of latency and packet loss.1 While basic SD- WAN functionality handles path selection, Application Acceleration goes further by employing Layer 4 (TCP) and Layer 7 (Application) optimizations. These optimizations are particularly effective for organizations with diverse branch environments where network conditions are unpredictable.
At Layer 4, Prisma SD-WAN implements TCP optimization techniques such as window scaling, selective acknowledgments, and congestion control algorithms.2 These mechanisms allow the ION devices to "trick" the end hosts into sending data faster by acknowledging packets locally, effectively shielding the application from the round-trip time (RTT) delays inherent in long-distance WAN circuits. This significantly boosts throughput for bulk data transfers and legacy protocols that were not originally designed for high-latency environments.
At Layer 7, the system can perform application-specific optimizations, such as metadata caching or protocol- specific acceleration for services like SMB or HTTP.3 By reducing the number of "chatty" exchanges required to complete a transaction, Prisma SD-WAN ensures a snappy, consistent user experience regardless of whether the user is on a high-speed fiber link or a degraded cellular connection. This is distinct from Forward Error Correction (FEC) (Option C) or Packet Duplication (Option A), which focus on reconstructing lost packets rather than optimizing the protocol throughput itself. By combining these L4 and L7 techniques, Application Acceleration ensures that business-critical SaaS and data center applications perform optimally across the entire distributed enterprise.
