Which statements accurately describes how the Prisma SD-WAN zone-based firewall functions within a branch network?
正解：B
解説：
The Prisma SD-WAN (ION) device includes a native, application-aware Zone-Based Firewall (ZBFW) that provides comprehensive security within the branch without the mandatory requirement for additional hardware.2 The fundamental principle of this architecture is the grouping of interfaces and sub-interfaces into logical Security Zones.3 Once these zones are defined (e.g., LAN, WAN, Guest, IoT), the administrator can create security policies that govern the traffic permitted to flow between them.4 Unlike traditional routers that rely on stateless Access Control Lists (ACLs) which are difficult to manage and lack application visibility, the Prisma SD-WAN ZBFW is stateful and application-aware.5 This means it can apply granular control over North-South traffic (flows moving between the LAN and the WAN/Internet) and East-West traffic (flows moving between different segments within the LAN, such as from a Guest zone to a Corporate zone).6 By using security zones, an ION device can ensure that even if two local networks are connected to the same physical appliance, they remain completely isolated unless a specific policy explicitly allows communication.
This "Zero Trust" approach at the branch edge allows organizations to segment vulnerable devices (like IoT) from critical internal resources and strictly control how users access the internet or the corporate data center.7 The ZBFW works in tandem with the global controller to ensure that security postures are consistent across all branch locations, eliminating the complexity of manual ACL management at each site.8

Which metrics can be monitored at the individual Prisma SD-WAN ION device level to assess its health and operational performance?
正解：B
解説：
To ensure the stability and performance of the SD-WAN fabric, Prisma SD-WAN provides granular visibility into the health of each Instant-On Network (ION) appliance. While the solution is primarily application- defined, monitoring the underlying physical and system resources of the hardware or virtual instance is critical for proactive maintenance and troubleshooting.
At the individual device level, administrators can monitor system resource utilization, which includes CPU usage, memory (RAM) consumption, and disk space availability.1 High CPU or memory usage can indicate that the device is reaching its throughput limits or that a specific process (such as deep packet inspection) is overtaxing the system. Disk utilization is monitored to ensure there is sufficient space for local logs and system operations.
Beyond internal system health, interface-level metrics are essential. This includes monitoring interface bandwidth utilization to identify bottlenecks on WAN or LAN ports. Crucially, operational performance is also assessed through error and discard counters on each interface. High error rates or frequent packet discards often signal physical layer issues (like bad cabling), duplex mismatches, or upstream provider congestion. While VPN status and application flows are vital for network-wide visibility, the core health of an ION device is defined by these foundational system and interface metrics.
Monitoring these specific parameters allows network engineers to distinguish between an application performance issue caused by network latency and one caused by a local hardware resource constraint.
質問 # 49
Which action meets the needs of an organization that requires elevated incident notifications for its headquarters location?
正解：D
解説：
In the Prisma SD-WAN (Instant-On Network) management framework, administrators can customize how events are handled and prioritized across different sites through Event Policies. An organization that requires
"elevated incident notifications" for a critical site like its headquarters needs a way to differentiate those alerts from standard branch notifications in the management portal and integrated third-party tools.
The most direct and effective method to achieve this is by configuring an Event Policy Rule specifically for the headquarters site. Within the incident policy framework, administrators can create rules that match specific resources-in this case, the headquarters site-and apply an action to set the priority. Priority levels typically range from P1 (highest) to P5 (lowest).1 By setting these to the highest level (P1), any generated incident for that site will immediately stand out on the dashboard as a high-priority event.
This approach is superior to other options because it changes the inherent importance of the alert within the Prisma SD-WAN logic itself. For example, a "WAN Link Down" event at a small retail branch might be a P3, but the same event at the HQ could be elevated to a P1 via a custom policy rule. This elevation ensures that the Network Operations Center (NOC) is alerted more urgently and that external integrations, such as ServiceNow or PagerDuty, receive the correct priority mapping for immediate escalation. Options such as aggressive SLA thresholds (Option B) only increase the frequency of alerts, not necessarily their notification priority, while global syslog or SNMP settings (Options A and D) lack the site-specific granularity required for this use case.
質問 # 50
What does Prisma SD-WAN use for monitoring and operations to deliver flow data and application visibility?
正解：C
解説：
Prisma SD-WAN is built on an application-defined fabric that prioritizes deep visibility into network traffic and application performance.1 To deliver the high-fidelity flow data and application visibility required for modern operations, Prisma SD-WAN utilizes IPFIX (Internet Protocol Flow Information Export).2 IPFIX is a standardized protocol based on NetFlow v9 that allows for the export of IP flow information from network devices to a collector or management system.3 In the Prisma SD-WAN architecture, ION devices act as the exporters.4 Because the system is application- aware, it doesn't just export basic 5-tuple information (source/destination IP, ports, and protocol); it exports rich metadata including application IDs, performance metrics (latency, jitter, packet loss), and path information. This allows the Prisma SD-WAN Controller and the associated Analytics engine to reconstruct a complete picture of every flow in the network.
While other protocols like SNMPv3 are supported for basic device health monitoring (such as CPU or interface status) and ADEM (Autonomous Digital Experience Management) provides end-to-end visibility for mobile users or SASE-connected branches, IPFIX is the primary "engine" for flow-level data across the SD-WAN fabric. Unlike traditional IP SLA, which relies on synthetic probes, the IPFIX-based monitoring in Prisma SD-WAN uses real-time application traffic to assess performance. This ensures that the visibility provided in the Flow Browser and Analytics dashboards accurately reflects the actual user experience, enabling granular troubleshooting and proactive capacity planning.
質問 # 51
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?
正解：C
解説：
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.
