NEW QUESTION # 57
Site templates are to be used for the large-scale deployment of 100 Prisma SD-WAN branch sites across different regions.
Which two statements align with the capabilities and best practices for Prisma SD-WAN site templates? (Choose two.)
Answer: A,C
Explanation:
Comprehensive and Detailed Explanation
Site Templates (often referred to as Site Configuration Templates) are a critical tool for the Zero Touch Provisioning (ZTP) of large-scale deployments in Prisma SD-WAN.
1. Device Pre-staging (Statement C):
One of the primary capabilities of Site Templates is the creation of Device Shells. A device shell is a configuration container that exists in the controller before the physical hardware is installed or connected. By using a template, an administrator can pre-provision the entire configuration (interfaces, routing, subnets) for the "Site" and "Element" (Device). When the physical ION device is later connected to the internet and claimed (associated with the shell via its Serial Number), it immediately inherits this pre-staged configuration, enabling a true "plug-and-play" deployment.
2. Mandatory Variables (Statement B):
To successfully instantiate a functional site from a generic template, specific unique identifiers are required in the variable data set (typically a CSV file).
Site Name: Identifies the location in the portal.
ION Software Version: Ensures the device boots to the specific validated code version required for the deployment, preventing inconsistencies.
ION Serial Number / Device Name: Required to bind the logical configuration (Shell) to the physical hardware. Even if the serial is added later during the claim process, the structure of the template and the deployment workflow mandates these variables to ensure the device can be uniquely identified and managed within the fabric.
Note on Option D: While it is technically possible to re-deploy a template, the Best Practice for "Day 2" operations (updating or modifying configuration after deployment) is to use Prisma SD-WAN Stacks (Network Stacks, Security Stacks, etc.). Stacks allow for granular, policy-based updates across multiple sites without the destructive or rigid nature of re-applying a full site initialization template. Therefore, D is not the aligned best practice.
NEW QUESTION # 58
When configuring a Path Policy rule for a "Real-Time Video" application, the administrator wants to ensure the traffic uses the path with the lowest packet loss.
How does the Prisma SD-WAN ION determine the "Packet Loss" metric for a given path when there is no active user traffic flowing on that link?
Answer: B
Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN utilizes Link Quality Monitoring (LQM) to maintain a real-time health score for every WAN path.
To ensure the system knows the quality of a path before sending critical user traffic onto it, the ION device uses Active Probing.
Mechanism: The ION sends synthetic probe packets (typically UDP) across the Secure Fabric (VPN tunnels) and Direct Internet paths to its peers. These probes measure Latency, Jitter, and Packet Loss.
Active vs. Passive: While the system does use Passive Monitoring (observing actual user flows) when traffic is present to reduce overhead, Active Probes are essential for idle links or backup paths. Without active probing, the ION would have no data to make an intelligent steering decision for the first packet of a new video call. This ensures that "Real-Time" policies always have up-to-date metrics to select the best path immediately.
NEW QUESTION # 59
A network installer is attempting to claim a new ION device using the "Claim Code" method. The device is connected to the internet, but the status in the portal remains stuck at "Claimed" and does not transition to "Online". The installer connects a laptop to the LAN port of the ION and can successfully browse the internet, confirming the uplink is active.
What is the most likely cause of the device failing to reach the "Online" state?
Answer: D
Explanation:
Comprehensive and Detailed Explanation
The transition from "Claimed" to "Online" depends entirely on the ION device's ability to establish a secure, persistent management tunnel to the Prisma SD-WAN Controller.
Connectivity Requirements: The ION device initiates an outbound connection to the controller on TCP Port 443 (HTTPS). It also requires accurate time synchronization to validate SSL certificates, necessitating access to NTP (UDP Port 123).
Scenario Analysis: Since the installer can browse the internet from the LAN, we know the physical link and basic routing/NAT are functional. The issue is specific to the management plane traffic.
Root Cause: If an upstream firewall (e.g., a corporate edge firewall or ISP filter) is inspecting SSL traffic or blocking specific FQDNs/Ports required by the ION, the device cannot complete the handshake. Consequently, it remains "Claimed" (registered in the database) but cannot go "Online" (active management session). Options A, C, and D prevent provisioning (configuration push) but generally do not prevent the device from initially checking in and going "Online" if the pipe is open.
NEW QUESTION # 60
A network engineer is troubleshooting an ION device that is showing as "Offline" in the Prisma SD-WAN portal, despite the site reporting that local internet access is working. The engineer has console access to the device.
Which CLI command should be used to specifically validate the device's ability to resolve the controller's hostname and establish a secure connection to it over a specific interface?
Answer: C
Explanation:
Comprehensive and Detailed Explanation
The CLI command debug controller reachability <interface> (e.g., debug controller reachability 1) is the specific diagnostic tool designed to verify the entire connectivity chain required for management plane availability.
Unlike a simple ICMP ping (Option A), which only tests Layer 3 connectivity to an IP address, the debug controller reachability command performs a sequential set of tests:
DNS Resolution: It attempts to resolve the specific Locator service URL (locator.cgnx.net or region-specific FQDN) to verify DNS functionality.
TCP Connectivity: It tests the ability to establish a TCP connection to the controller on port 443 (HTTPS).
SSL/TLS Handshake: It validates that the device can successfully negotiate the secure tunnel required for authentication.
If this command fails at the DNS step, the issue is likely a missing DNS server in the interface config. If it fails at the TCP step, it implies an upstream firewall is blocking outbound port 443. This targeted output allows the engineer to pinpoint exactly why the device is offline in the portal.
NEW QUESTION # 61
A network operator receives a critical SITE_CONNECTIVITY_DOWN alarm for a branch site in the Prisma SD-WAN portal.
What specific condition triggers this alarm type?
Answer: A
Explanation:
Comprehensive and Detailed Explanation
The SITE_CONNECTIVITY_DOWN alarm is a high-severity alert indicating a total loss of overlay connectivity for a site.
It does not trigger if just one circuit fails (Option B), provided that other circuits are still up and maintaining VPNs. A single link failure would typically trigger a "Link Down" or "VPN Down" alarm, but the Site connectivity would remain "Up" (degraded).
It does not simply mean the device rebooted (Option A), although a reboot would cause it temporarily; the alarm specifically tracks the state of the VPN fabric.
The SITE_CONNECTIVITY_DOWN alarm specifically generates when all Secure Fabric Links (VPN tunnels) on the device are in the "Down" state. This means the branch is completely isolated from the rest of the SD-WAN network (Data Centers and other branches), even if the device itself might still be powered on and reachable via the controller (management plane). It signifies a "Blackout" of the data plane for that location.
