質問 # 35
Based on the HA topology image below, which two statements describe the end-state when power is removed from the ION 1200-S labeled "Active", assuming that the ION labeled "Standby" becomes the active ION?
(Choose two.)
正解：B、C
解説：
Prisma SD-WAN High Availability (HA) for branch ION devices, particularly the Gen-2 ION 1200-S, is designed to provide "100% WAN Capacity" preservation during a hardware or power failure. This is achieved through the use of Bypass Pairs (Fail-to-Wire). In the provided topology, the ISP A and LTE/5G circuits are cross-connected using the bypass ports (typically ports 3 and 4 on the ION 1200-S).
When the "Active" ION device loses power, the internal physical relays in its bypass ports transition to a closed state, effectively creating a physical bridge between the ports. In this scenario, the LTE/5G signal- which enters the Active ION's port 4-is mechanically bridged to port 3, allowing it to pass through to port 4 of the Standby ION. Simultaneously, ISP A is already connected to the Standby ION. Consequently, once the Standby device completes its transition to the "Active" state, it has physical access to both WAN circuits, validating Statement A.
Regarding the LAN transition, Prisma SD-WAN does not use standard VRRP for ION-to-ION HA; instead, it uses a proprietary Control Plane HA mechanism. When the failover occurs, the newly active ION takes over the IP addresses of all configured Switch Virtual Interfaces (SVIs) and LAN interfaces. To ensure the downstream Layer 2 infrastructure (like the LAN switches shown in the diagram) updates its MAC address tables to point to the new physical hardware for those IPs, the newly active ION immediately broadcasts a Gratuitous ARP (GARP). This ensures that LAN traffic is correctly steered to the new device without a significant timeout, validating Statement C.
質問 # 36
What is the basis for calculating the minimum bandwidth subscription required for branch IONs?
正解：C
解説：
Palo Alto Networks utilizes an aggregate throughput model for Prisma SD-WAN licensing.1 The minimum bandwidth subscription required for a branch ION is determined by the maximum traffic (the sum of both ingress and egress) that passes through the ION device. This is often referred to as "Aggregate Throughput." It is a critical distinction in the Prisma SD-WAN architecture because the license must account for all traffic processed by the device, whether that traffic stays local (Direct Internet Access), goes to the Data Center via the VPN fabric, or moves between local LAN segments.
When sizing a subscription, engineers must evaluate the total capacity of the WAN circuits connected to the branch. For example, if a branch has two 100 Mbps internet circuits, the device is capable of processing 200 Mbps of egress traffic and 200 Mbps of ingress traffic simultaneously. However, the licensing is based on the aggregate peak throughput the customer expects to utilize across the device's interfaces.
Choosing an under-sized subscription based only on "fabric traffic" (Option B) or "ISP capacity" (Option D) without considering the total bi-directional flow can lead to artificial performance bottlenecks. If the traffic exceeds the licensed bandwidth, the ION device will police the traffic to the licensed limit, regardless of the physical port speed or the hardware's theoretical maximum. Therefore, the subscription must be aligned with the total actual traffic volume the device is expected to handle to ensure an optimal user experience and full utilization of available circuit bandwidth.
質問 # 37
A remote branch site is reporting intermittent connectivity to the Data Center. The administrator checks the System > Alarms page and sees a "VPN_DOWN" alarm for the tunnel to the DC. However, the internet circuit status is "Up".
Which specific log file or diagnostic tool in the Prisma SD-WAN portal would provide the IKE (Internet Key Exchange) error codes (e.g., "NO_PROPOSAL_CHOSEN" or "AUTH_FAILED") to pinpoint the cause of the tunnel failure?
正解：C
解説：
Comprehensive and Detailed Explanation
To diagnose specific VPN negotiation failures (Phase 1 or Phase 2 IPSec issues), the Event Logs (specifically filtered for System or VPN events) are the correct resource.
Event Logs: This section records the control plane signaling messages. If a VPN tunnel fails to establish, the Event Log will generate an entry containing the specific IKE failure reason sent by the peer or generated locally. Common errors found here include INVALID_COOKIE, NO_PROPOSAL_CHOSEN (mismatch in encryption algorithms), or PRE_SHARED_KEY_MISMATCH.
Flow Browser (A): This shows user traffic (TCP/UDP sessions). If the VPN is down, user traffic won't even enter the tunnel, so the Flow Browser will just show dropped flows or blackholes, but it won't explain why the tunnel itself is broken.
Link Quality (D): This shows latency/loss graphs for established tunnels. It cannot diagnose why a tunnel failed to form in the first place.
質問 # 38
A site has two internet circuits: Circuit A with 500 Mbps capacity and Circuit B with 100 Mbps capacity.
Which path policy configuration will ensure traffic is automatically shifted from a saturated circuit to the circuit with available bandwidth?
正解：B
解説：
Comprehensive and Detailed Explanation
In Prisma SD-WAN (CloudGenix), Path Policies control how application traffic is steered across WAN links. To ensure that traffic is automatically shifted from a saturated circuit to another circuit with available bandwidth, both circuits must be configured as Active Paths within the policy rule.
When multiple paths are designated as "Active," the ION device treats them as a shared pool of available resources. The system continuously monitors the bandwidth utilization (capacity) and health (latency, jitter, loss) of all active links. If "Circuit A" (500 Mbps) becomes saturated or approaches its defined bandwidth limit, the ION's intelligent scheduler will automatically direct new application flows to "Circuit B" (100 Mbps) because it is a valid, healthy Active path with available capacity. This achieves effective load balancing and bandwidth aggregation.
In contrast, configuring "Circuit B" as a Backup Path (Option A or B) creates a strict priority relationship. Traffic would only move to the Backup path if the Active path completely failed or violated its configured SLA (Path Quality Profile) significantly enough to be considered "down." Mere bandwidth saturation might not trigger an SLA failure immediately, potentially leading to dropped packets on the saturated link while the backup link remains idle. Therefore, placing Both circuits under active path is the correct configuration for dynamic capacity management.
質問 # 39
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.
