質問 # 45
A customer wants to deploy Prisma SD-WAN ION devices at small home offices that use consumer-grade broadband routers. These routers typically use Symmetric NAT and do not allow static port forwarding.
Which standard mechanism does Prisma SD-WAN utilize to successfully establish direct Branch-to-Branch (Dynamic) VPN tunnels through these Symmetric NAT devices?
正解：A
解説：
Comprehensive and Detailed Explanation
Prisma SD-WAN utilizes STUN (Session Traversal Utilities for NAT) to facilitate NAT Traversal for its Secure Fabric overlay.
Discovery: When an ION device connects to the internet behind a NAT router, it reaches out to the Prisma SD-WAN Controller. The controller acts as a STUN server, identifying the public IP address and port that the ION's traffic is originating from.
Symmetric NAT Challenge: In Symmetric NAT, the mapping changes for every destination. However, the Prisma SD-WAN architecture is designed to handle this by having the controller coordinate the connection attempt.
Hole Punching: The controller shares the discovered public mapping information between two peer ION devices. They then simultaneously initiate traffic to each other's public IP/Port (a technique called "UDP Hole Punching"). This tricks the intermediate NAT devices into allowing the inbound traffic, establishing a direct P2P IPSec tunnel without requiring manual port forwarding or static IPs at the edge.
質問 # 46
When identifying devices for IoT classification purposes, which two methods does Prisma SD-WAN use to discover devices that are not directly connected to the branch ION? (Choose two.)
正解：A、B
解説：
Comprehensive and Detailed Explanation
Prisma SD-WAN (formerly CloudGenix) integrates with Palo Alto Networks IoT Security to provide comprehensive visibility into all devices at a branch, including those that are not directly connected to the ION device. While the ION automatically detects and classifies devices connected directly to its interfaces via traffic inspection (DPI), DHCP, and ARP analysis, gaining visibility into off-branch devices (devices connected to downstream switches or access points) requires additional discovery mechanisms that can query the network infrastructure or ingest its logs.
1. SNMP (Simple Network Management Protocol): This is the primary active discovery method for off- branch devices. The Prisma SD-WAN ION device acts as a sensor that actively polls local network switches and wireless controllers using SNMP. By querying the ARP tables and MAC address tables (Bridge MIBs) of these intermediate network devices, the ION can identify endpoints that are connected to the switch ports, even if those endpoints are not currently sending traffic through the ION. This allows the system to map the topology and discover silent or lateral-traffic-only devices.
2. Syslog: In conjunction with SNMP, the IoT Security solution can utilize Syslog messages to discover and profile devices. Network infrastructure devices (like switches and WLAN controllers) can be configured to send Syslog messages to the collection point (which enables the IoT Security service) whenever a device connects or disconnects (e.g., port up/down events, DHCP snooping logs, or 802.1x authentication logs).
These logs provide real-time data about device presence and identity (MAC/IP mappings) for devices that are not directly adjacent to the ION, ensuring 100% visibility across the branch network segments. LLDP (A) and CDP (B) are typically Link Layer discovery protocols used for discovering directly connected neighbors and do not propagate beyond the immediate link, making them unsuitable for discovering devices multiple hops away or behind a switch.
質問 # 47
Which metrics can be monitored at the individual Prisma SD-WAN ION device level to assess its health and operational performance?
正解：C
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 # 48
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 # 49
An administrator is configuring a BGP peer on a Data Center ION to learn routes from the core switch. The goal is to have the ION learn these prefixes and then advertise them to all remote branch sites across the SD- WAN overlay.
Which setting must be configured on the BGP Peer to ensure these learned routes are redistributed into the SD-WAN fabric?
正解：C
解説：
Comprehensive and Detailed Explanation
In Prisma SD-WAN routing configuration, the Scope setting on a BGP Peer (or a Static Route) controls the redistribution logic for the prefixes learned from that source.
* Local Scope: If a BGP peer is configured with "Local" scope, the ION device will install the learned routes into its local routing table for its own reachability, but it will not advertise (redistribute) these routes to other ION devices via the Secure Fabric. They remain local to the site.
* Global Scope: To advertise reachability to the rest of the network, the BGP peer must be configured with "Global" scope. This tells the ION that any prefixes learned from this specific neighbor (e.g., the DC Core Switch) should be propagated across the SD-WAN overlay to remote branches. This is the critical setting for enabling branch-to-DC communication for applications hosted behind that BGP peer.
Without "Global" scope, the branches would never learn the routes to the data center subnets.
