質問 # 55
For how many hours are Prisma SD-WAN VPN shared secrets valid?
正解：D
解説：
In the Prisma SD-WAN architecture, security is built directly into the AppFabric using a centralized, controller-led approach to key management. Unlike traditional VPNs that rely on manual Internet Key Exchange (IKE) or static Pre-Shared Keys (PSKs) which can be administratively burdensome and security- vulnerable, Prisma SD-WAN automates the entire lifecycle of encrypted tunnels. The Prisma SD-WAN Controller acts as the central authority for identity and key distribution for all ION (Instant-On Network) devices within the tenant's fabric.
Specifically, the VPN shared secrets used to secure these tunnels are ephemeral and are valid for exactly 24 hours. This 24-hour validity period is a security best practice implemented by Palo Alto Networks to limit the
"blast radius" or window of exposure in the unlikely event that a key is compromised. The controller automatically handles the generation, distribution, and rotation of these secrets. Before the 24-hour timer expires, the controller pushes new keys to the ION devices, which then perform a hitless rollover. This ensures that the data plane remains active and encrypted without requiring manual intervention from a network administrator. If an ION device loses its control plane connection to the controller, it will maintain its existing tunnels using the current keys until they expire, at which point it must re-authenticate with the controller to receive a new set of valid secrets. This automated rotation is a core component of the Prisma SD- WAN Zero-Trust security model.

During the Zero Touch Provisioning (ZTP) process of a new ION device at a branch site, which interface ports are supported by default to request an IP address via DHCP and reach the Prisma SD-WAN controller for claiming?
正解：B
解説：
Comprehensive and Detailed Explanation
For a successful Zero Touch Provisioning (ZTP) experience, the ION device must be able to obtain an IP address and reach the internet immediately upon boot-up.
According to Palo Alto Networks hardware guides, the Controller Port (often labeled specifically as "CONTROLLER" on models like the ION 3000/7000/9000) is pre-configured to act as a DHCP client by default. It is the preferred interface for the initial "call home" process.
However, for smaller desktop models (like the ION 1000/2000/1200 series) or scenarios where a dedicated management network is not available, the device firmware is also configured to attempt DHCP client requests on Port 1 (often labeled as Internet 1 or simply 1).
Connecting the ISP circuit to any random port (like Port 4 or a LAN port) will not work for ZTP because those interfaces are not pre-configured as DHCP clients in the factory default state. Therefore, the installer must ensure the internet uplink is connected to either the dedicated Controller port or Port 1/Internet 1 to ensure the device can resolve the controller FQDN and download its configuration.
質問 # 57
What are two potential causes when a secondary public circuit has been added to the branch site, but the Prisma SD-WAN tunnel is not forming to the data center? (Choose two.)
正解：C、D
解説：
In a Prisma SD-WAN deployment, the formation of VPN tunnels between a branch ION device and a Data Center (DC) ION is governed by specific configuration parameters that define how an interface interacts with the WAN fabric. When a secondary public circuit is introduced, the system requires precise classification to initiate the negotiation of security associations.
The first critical factor is the Interface Role. For an ION device to attempt to build a global fabric tunnel over a public circuit, the interface must be explicitly assigned the "Internet" role. If the role is incorrectly set (e.g., as "LAN" or left unconfigured), the device will not treat that physical port as a viable path for the SD- WAN overlay, preventing the tunnel from initiating.
Secondly, the Circuit Label plays a vital role in the path selection and tunnel orchestration logic. Prisma SD- WAN uses labels to match local branch circuits with corresponding circuits at the data center or other branches. If a circuit label is missing or mismatched on the interface configuration, the Controller cannot properly orchestrate the "bind" between the branch and the hub. Without a valid label, the ION device doesn't know which path group the circuit belongs to, and consequently, the automated tunnel signaling process fails to complete.
While DNS is important for management connectivity to the Controller, it is generally not the primary blocker for site-to-site tunnel formation if the Controller reachability is already established via the primary circuit.
Similarly, "Interface Scope" is more relevant to routing advertisement rather than the foundational establishment of the SD-WAN tunnel itself. Therefore, ensuring the Internet role and Circuit Label are correctly applied is the standard troubleshooting step for non-forming tunnels on new circuits.
質問 # 58
In a Data Center deployment, what is the key functional difference between configuring a BGP neighbor as a
"Core Peer" versus an "Edge Peer"?
正解：B
解説：
Comprehensive and Detailed Explanation
In the Prisma SD-WAN Data Center (DC) model, the terminology for BGP peers defines their role in the topology and how the system generates route maps.
* Core Peer: This peer type is designated for the LAN-side connection (facing the DC Core Switch or internal Routers). Its primary purpose is to learn the subnets/prefixes hosted in the data center so the ION can advertise them to the remote branches. The system automatically creates route maps to facilitate this redistribution into the fabric.
* Edge Peer: This peer type is designated for the WAN-side connection (facing the Edge Router or MPLS PE). Its primary purpose is to provide reachability to the underlay network.
* Distinction: Selecting the correct type affects the default Route Maps and Prefix Lists generated by the controller. Configuring a Core Peer correctly ensures that the DC's internal subnets are properly learned and propagated to the overlay, whereas an Edge Peer configuration focuses on WAN next-hop reachability.
質問 # 59
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:
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：A、D
解説：
The provided graph displays the Signal-to-Noise Ratio (SNR) for two cellular carriers, Carrier-1 (blue line) and Carrier-2 (green line), over a specific period. In cellular communications, SNR is a critical metric used to determine the quality of a wireless signal. A higher SNR indicates a cleaner, stronger signal, while a lower SNR indicates that the signal is being "drowned out" by background noise or interference, which directly correlates to performance degradation, packet loss, and lower throughput.
Looking at the graph, Carrier-1 experiences a significant and sustained drop in SNR, falling from roughly
4.5 dB to nearly 0.5 dB for the majority of the time duration. This drastic reduction in signal quality strongly suggests that Carrier-1 may have experienced performance degradation (Option A). During this dip, the link quality would likely fall below the configured thresholds for business-critical application traffic.
Because Prisma SD-WAN is an application-defined fabric that continuously monitors path health, the ION device would detect this degradation on Carrier-1. If Carrier-2 maintains a significantly higher and more stable SNR (as shown by the green line remaining between 4.5 dB and 6.5 dB), the ION device's Path Selection engine would automatically steer traffic away from the degraded link. Consequently, it is highly probable that Carrier-1 traffic switched over to Carrier-2 (Option D) to maintain the application SLA. This automated failover is a core strength of the Prisma SD-WAN architecture, ensuring that the best available path is utilized based on real-time link statistics rather than simple "up/down" states.
