NEW QUESTION # 20
An ION 3000 device at a remote branch has suffered a critical hardware failure and must be replaced via the RMA process. The administrator has received the replacement unit.
What is the correct procedure to transfer the configuration and license from the defective unit to the replacement unit to ensure minimal downtime and retention of historical data?
Answer: B
Explanation:
Comprehensive and Detailed Explanation
The RMA replacement process in Prisma SD-WAN is designed to be seamless, leveraging the decoupling of logical configuration from physical hardware.
* Replace Device Workflow: The administrator should use the "Replace Device" (or RMA) function within the portal. This workflow allows you to select the "Defective" device (old serial) and the
"Replacement" device (new serial).
* Configuration Transfer: Once executed, the system automatically binds the existing Device Shell (which contains all interface configs, routing policies, and site associations) to the new hardware's serial number. The new device, once connected to the internet, will "call home," identify itself, and download the exact configuration of the previous unit.
* License Transfer: While the configuration moves automatically, the Support License transfer typically requires a specific step in the Customer Support Portal (CSP) or happens automatically if processed as a formal RMA order. Options A and D are incorrect because they involve manual reconfiguration, which is unnecessary and error-prone. Option C is incorrect as the ION platform relies on cloud-based config management, not local USB backups for hardware swaps.
NEW QUESTION # 21
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?
Answer: A
Explanation:
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.
NEW QUESTION # 22
Which IONs can support Branch Gateway?
Answer: C
Explanation:
In the Prisma SD-WAN ecosystem, ION (Instant-On Network) devices are categorized based on their performance capabilities, throughput, and their specific role within the network architecture-namely, whether they function as a Branch device or a Data Center (DC) device.2 The "Branch Gateway" designation typically refers to high-capacity hardware or virtual instances designed to handle complex routing, massive throughput, and high-density connectivity requirements found in large branch offices or regional hubs.
The devices listed in option D represent the high-performance tier of the ION family. The ION 9200 and ION
5200 are flagship hardware appliances designed for large-scale deployments, offering multi-gigabit throughput and extensive port density.3 The ION 3200 serves as a robust mid-to-high range branch solution.4 The ION 7116V is a high-capacity virtual appliance (part of the 7000 series) designed to provide flexible, software-defined gateway capabilities in virtualized environments or public clouds (like AWS, Azure, or GCP).
Specifically, these models support advanced features such as Layer 3 hardware forwarding, integrated switching (in certain sub-models), and the processing power required to run deep packet inspection (DPI) for application-based path selection at scale. While smaller units like the 1200 series are excellent for small-to- medium branches, the 9200, 3200, 5200, and 7116V are the primary workhorses for organizations requiring
"Gateway" class performance to manage heavy traffic loads and maintain high availability in a Prisma SD- WAN fabric.
NEW QUESTION # 23
In the Prisma SD-WAN portal, an administrator is viewing the "Media" analytics for a branch site to troubleshoot complaints about poor voice quality.
When calculating the Mean Opinion Score (MOS) for voice traffic, which two metrics does the system prioritize active monitoring for, even when no user voice traffic is present on the link? (Choose two.)
Answer: B,C
Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN calculates the Mean Opinion Score (MOS) to provide a standardized metric (1-5) for voice quality. To ensure the system always knows the "voice readiness" of a path-even before a call starts-it uses Active Probes (synthetic UDP packets).
While latency is measured, the MOS calculation algorithm is most heavily penalized by Packet Loss (D) and Jitter (B).
Packet Loss: Even a small amount of loss (e.g., >1%) dramatically reduces voice clarity, causing dropouts.
Jitter: High variance in packet arrival time (jitter) causes the "robotic" voice effect and buffer underruns.
The system continuously measures these specific metrics on all WAN links using synthetic probes. If the packet loss or jitter exceeds the threshold defined in the "Path Quality Profile" (e.g., Voice Profile), the path is marked as non-compliant, and the MOS score drops, triggering a policy action to move the flow. Throughput (C) is less critical for voice as calls consume very little bandwidth (e.g., 64-100 Kbps), making congestion (loss/jitter) the primary enemy, not raw speed.
NEW QUESTION # 24
An administrator wants to configure a Path Policy that routes all "Guest Wi-Fi" traffic directly to the internet using the local broadband interface, bypassing all VPN tunnels.
Which Service & DC Group setting should be selected in the policy rule to achieve this "Direct Internet Access" (DIA) behavior?
Answer: A
Explanation:
Comprehensive and Detailed Explanation
In Prisma SD-WAN Path Policies, the Service & DC Group (Destination) field determines where the traffic is sent.
Direct: This is the specific keyword/object used to instruct the ION to route traffic directly out to the local WAN interface (Local Breakout) towards the Internet, without encapsulation in a VPN tunnel. This is the correct setting for Guest Wi-Fi, SaaS applications (like Office 365), or any public web browsing that does not need to be backhauled.
Standard VPN / Default-Cluster: These options direct traffic into an IPSec overlay tunnel destined for a Data Center or another ION. Selecting these would "backhaul" the guest traffic, which contradicts the requirement for DIA.
When "Direct" is selected, the ION uses its available "Internet" category links. The policy can further specify which internet link to use (e.g., "Use Broadband, avoid LTE") via the path preference list, but the Destination type must be "Direct".
