質問 # 46
A network engineer is troubleshooting a "Voice Quality" issue. They suspect that the DSCP markings are being stripped or altered by the ISP.
Which tool in the Prisma SD-WAN portal allows the engineer to capture live packets on the WAN interface and inspect the IP header ToS/DSCP field?
正解：B
解説：
Comprehensive and Detailed Explanation
To validate specific packet-level details like DSCP (Differentiated Services Code Point) values, header checksums, or exact payload sizes, a Packet Capture (PCAP) is required.
PCAP Tool: Prisma SD-WAN provides a built-in PCAP utility accessible directly from the portal. The engineer can select the specific Interface (e.g., Internet 1), apply a Filter (e.g., port 5060 or host 1.2.3.4), and capture the traffic.
Analysis: The resulting .pcap file can be downloaded and opened in Wireshark. This allows the engineer to definitively see if the packets leaving the ION have DSCP EF (46) and if the packets arriving (if capturing on the other side) still retain that marking, or if the ISP has bleached it to CS0 (0).
Flow Browser (A): While it shows "Application" and metrics, the Flow Browser typically displays the assigned priority class, not necessarily the raw bit-level DSCP value present in the packet header on the wire.
質問 # 47
Which configuration requirement must be met to allow two branch ION devices to automatically establish a direct Dynamic VPN (branch-to-branch) connection for traffic flow, bypassing the Data Center?
正解：C
解説：
Comprehensive and Detailed Explanation
Dynamic VPNs (also known as ION-to-ION or Branch-to-Branch VPNs) allow Prisma SD-WAN devices to establish direct, on-demand secure tunnels between branch sites to optimize latency for peer-to-peer traffic (e.
g., VoIP calls between offices).
To enable this capability, the primary architectural requirement is the configuration of VPN Clusters.
A VPN Cluster defines a logical group of devices that are authorized to communicate with one another.
* By default, or if devices are in different clusters without peering, the topology typically defaults to Hub- and-Spoke, where branches only talk to the Data Center.
* When two branch ION devices are placed into the same VPN Cluster (or peered clusters), the controller shares the necessary reachability and cryptographic information between them.
Once in the same cluster, the ION devices monitor traffic. If a user at Branch A tries to contact a server at Branch B, the ION devices detect this interest. If a direct path is available (e.g., via public internet), they will dynamically negotiate a direct VPN tunnel, bypassing the Data Center hub. This offloads the hub and reduces latency. Option B is incorrect because SD-WAN eliminates manual GRE config. Option C is incorrect because dynamic VPNs are a performance feature, not just a disaster recovery feature.
質問 # 48
There are periodic complaints about the poor performance of a real-time application.
What can be inferred about the performance issue, based on the Network Transfer Time (NTT) and Server Response Time (SRT) image below?
正解：A
解説：
In Prisma SD-WAN, application performance is monitored through distinct metrics that separate network health from application health. The provided graph displays Network Transfer Time (NTT) in blue and Server Response Time (SRT) in orange. NTT measures the round-trip time of packets traversing the WAN fabric, while SRT measures the time elapsed from when the server receives a request to when it sends the first response packet.
Analysis of the telemetry data shows that the NTT (blue line) remains consistently low and stable, generally staying below 100 milliseconds throughout the capture period. This indicates that the SD-WAN path and underlying network circuits are not the source of the latency. Conversely, the SRT (orange line) exhibits significant and erratic spikes, reaching as high as 450 to 475 milliseconds. These spikes occur while the network latency (NTT) remains flat.
Because the latency increases are isolated to the SRT metric, the root cause is confirmed to be on the Application Server side. This pattern typically suggests that the server is struggling with resource exhaustion, high CPU utilization, or database query delays during peak processing times. For a real-time application, these SRT spikes translate directly to jitter and "lag" for the end-user. By distinguishing between these two metrics, Prisma SD-WAN allows network administrators to prove that the network is performing within SLA and shift the troubleshooting focus to the application or server management teams, significantly reducing mean time to innocence (MTTI).
質問 # 49
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?
正解：D
解説：
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.
質問 # 50
In which modes can a Prisma SD-WAN branch be deployed?
正解：A
解説：
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.
