問題 #84
The UI triggers incident DEVICESW_CONCURRENT_FLOWLIMIT_EXCEEDED for a branch site. Based in the image below, which tool can be used to identify the host?
答案：B
解題說明：
When a Prisma SD-WAN ION device triggers the
DEVICESW_CONCURRENT_FLOWLIMIT_EXCEEDED incident, it indicates that the number of active sessions has reached the hardware or software-defined capacity limit of that specific appliance. In the provided graph, we can see a massive spike in concurrent TCP flows on May 13th, reaching nearly 500k, which is a clear indicator of anomalous behavior-likely a "top talker" host, a malware outbreak, or a misconfigured application generating excessive connections.
To identify the specific host responsible for this surge, administrators should navigate to Monitor # Activity
# Flows. This interface, commonly known as the Flow Browser, provides the most granular visibility into real-time and historical session data within the Prisma SD-WAN fabric. Unlike "Transaction Stats," which provide high-level summaries, or "New Flows," which only show the rate of session initiation, the Flows view allows an engineer to filter and sort the active session table by metadata such as Source IP, Destination IP, Application, and Site.
By utilizing the Flow Browser, an administrator can quickly group flows by "Source IP" to pinpoint exactly which internal host is consuming the most flow table entries. This is the standard "Day 2" operational workflow for troubleshooting performance and capacity incidents. While running a tcpdump (Option A) is a valid diagnostic for packet-level analysis, it is inefficient for identifying a single host among hundreds of thousands of flows and can further tax the device's CPU during a high-load event. The Monitor # Activity # Flows tool is designed specifically for this type of scale, providing the necessary visibility to remediate the flow limit exhaustion and restore normal network operations.
問題 #85
BGP core peers on data center IONs are learning only a default route from the core router. Which action will protect the SD-WAN network from getting isolated in the event of BGP misconfiguration on the core routers?
答案：C
解題說明：
In a Data Center (DC) deployment, the ION device typically peers with a core router via Border Gateway Protocol (BGP) to exchange reachability information between the SD-WAN fabric and the legacy corporate network.2 When the ION is configured to learn only a default route ($0.0.0.0/0$) from the core, the entire SD- WAN fabric relies on this single BGP-learned route to reach internal resources not directly connected to the ION.
The primary risk in this design is network isolation caused by a BGP misconfiguration or a "soft failure" on the core router. If the BGP session stays "Up" but the core router stops advertising the default route due to a configuration error, the ION device will remove the route from its routing table. Without a valid path to the core, the branch sites connected to the DC ION will lose connectivity to all data center resources.
To mitigate this, the recommended best practice is to add a static default route with a higher Administrative Distance (AD) pointing to the core peer IPs.3 This acts as a "floating static route." Under normal operations, the BGP-learned default route (typically with an AD of 20 for eBGP) remains active in the routing table. If the BGP advertisement fails, the static route with the higher AD (e.g., 250) becomes active.
This ensures that the ION device maintains a persistent gateway toward the core infrastructure, preventing total fabric isolation and providing a fail-safe mechanism while the BGP peering issue is remediated. While BFD (Option A) helps with fast peer failure detection, it does not solve the issue of a missing prefix advertisement. Static route redundancy provides the necessary architectural "safety net" for the data center's reachability.
問題 #86
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?
答案：C
解題說明：
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.
問題 #87
A branch manager reports slow network performance, and the network administrator wants to use Prisma SD- WAN Copilot to quickly identify if a specific user, by source IP address, is consuming excessive bandwidth as well as which applications are contributing to this consumption. How can Copilot assist in this investigation?
答案：B
解題說明：
Prisma SD-WAN Copilot is an AI-powered operational tool designed to simplify network management through Natural Language Processing (NLP). Traditionally, identifying a bandwidth "hog" required manual navigation through multiple dashboards, such as WAN Clarity and the Flow Browser, to correlate source IP addresses with specific application flows and timestamps. Copilot transforms this workflow by allowing administrators to interact with the system using conversational queries.
When an administrator inputs a query like "Show top bandwidth source IPs at SD-WAN Branch X over last 3 hours," Copilot leverages its underlying machine learning models and integrated data lake to aggregate telemetry across the entire fabric. It instantly identifies the specific source IPs responsible for the highest throughput and correlates that data with application visibility. Instead of providing a static report or redirecting the user to other tools, Copilot presents an interactive, summarized view directly within the interface. This view highlights the top-consuming users and breaks down their consumption by application, such as YouTube, Netflix, or business-critical SaaS tools.
This capability significantly reduces the Mean Time to Resolution (MTTR) for performance issues. By bypassing the need for manual data correlation, Copilot provides immediate "Day 2" operational insights. It effectively acts as a virtual assistant that understands the context of the network topology, site names, and time ranges, allowing the administrator to quickly determine if a branch's slow performance is due to an individual user's behavior or a broader infrastructure issue.
問題 #88
An administrator is configuring a High Availability (HA) pair of ION 3000 devices at a Data Center.
Which statement accurately describes the requirement for the HA Control Interface connection between the two devices?
答案：B
解題說明：
Comprehensive and Detailed Explanation
In a Prisma SD-WAN High Availability (HA) deployment, the HA Control Interface is the critical lifeline used to synchronize state, heartbeats, and flow information between the Active and Standby ION devices.
The strict requirement for this connection is that it must be Layer 2 adjacent.
Best Practice: A direct physical cable connection between the designated HA ports of the two devices (e.g., Port 2 on Device A to Port 2 on Device B).
Alternative: Connectivity through a switch on a dedicated, isolated VLAN is supported, provided the devices are in the same broadcast domain and subnet.
Routing (Layer 3) is not supported for the HA Control link because the keepalive mechanism relies on low-latency, multicast/broadcast-level adjacency to detect failures instantly (sub-second failover). If the HA link were routed (Option A), network latency or router convergence issues could cause "Split-Brain" scenarios where both devices assume the Active role, leading to IP conflicts and traffic loops. Option C is incorrect because the Controller is too slow to manage real-time failover; the decision must be local.
