Palo Alto Networks SD-WAN Engineer SD-WAN-Engineer Prüfungsfragen mit Lösungen (Q72-Q77):

72. Frage
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?

A. It sends Active Probes (synthetic UDP packets) across the Secure Fabric to measure path quality continuously.
B. It queries the ISP's router via SNMP to retrieve interface error counters.
C. It defaults to a static value of 0% loss until user traffic begins.
D. It relies solely on Passive Monitoring of TCP retransmissions from other user traffic on that link.

Antwort: A

Begründung:
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.

73. Frage
An administrator has configured a Path Policy for "ERP_Traffic". The policy allows two public internet links,
"ISP-A" and "ISP-B", both marked as "Active". The Path Quality Profile (SLA) requires a latency of less than
150ms. Currently, both ISP-A and ISP-B have a latency of 40ms, well within the SLA.
How does the Prisma SD-WAN ION determine which link to use for a new flow of "ERP_Traffic" when both active paths meet the SLA requirements?

A. It selects the path with the lowest numerical latency (e.g., if ISP-A drops to 39ms).
B. It duplicates the packets across both paths (Packet Duplication) to ensure delivery.
C. It selects the path with the highest available bandwidth capacity.
D. It selects the path that appears first in the interface configuration list.

Antwort: C

Begründung:
Comprehensive and Detailed Explanation
Prisma SD-WAN utilizes a sophisticated decision engine for Application-Based Path Selection that goes beyond simple failover. When configuring a Path Policy, the administrator defines "Active" paths and a "Path Quality Profile" (SLA).
* SLA Compliance (The Filter): First, the system filters the available paths based on the Path Quality Profile. In this scenario, both ISP-A and ISP-B have 40ms latency against a 150ms threshold. Both are
"green" or compliant paths.
* Selection Criteria (The Tie-Breaker): When multiple paths are configured as "Active" and all meet the performance SLA, the ION device aims to optimize the overall user experience and network utilization. The default behavior for load balancing across healthy, compliant active paths is to select the path with the highest available bandwidth capacity.
By steering new flows to the link with the most "headroom" (available Mbps), the system prevents the saturation of a smaller link (e.g., a 20Mbps DSL line) while a larger link (e.g., 1Gbps Fiber) sits underutilized.
This maximizes the aggregate throughput for the site. While latency is the qualifier, bandwidth availability is often the selector for compliant paths. Note that if the application was defined as "Real-Time" and configured for packet duplication, behavior would differ, but for standard traffic, capacity-based distribution is the standard active/active logic.

74. Frage
A network administrator is viewing the Flow Browser to investigate a report that a specific user cannot access an internal web server. The flow entry for this traffic shows the "Flow State" as "INIT" and it remains in that state until it times out.
What does the "INIT" state indicate about the traffic flow?

A. The TCP 3-way handshake was completed successfully, and data is being transferred.
B. The traffic is being buffered while the ION waits for a dynamic VPN tunnel to establish.
C. The ION device received the SYN packet from the client but never saw a SYN-ACK response from the server.
D. The flow was denied by a Zone-Based Firewall policy on the ION.

Antwort: C

Begründung:
Comprehensive and Detailed Explanation
In the Prisma SD-WAN Flow Browser, the Flow State provides a real-time snapshot of the TCP/UDP session lifecycle.
INIT (Initialization): This state indicates that the ION device has seen the initial packet of a new session (typically a TCP SYN) originating from the client (Source), but it has not yet seen a return packet (such as a TCP SYN-ACK) from the destination server.
Diagnosis: A flow stuck in INIT is a classic indicator of a "Blackhole" or reachability issue downstream. It implies that the ION successfully routed the packet out toward the destination, but the destination did not reply. Common causes include:
The server is offline.
A firewall in the path (or on the server itself) is dropping the traffic.
Routing is broken on the return path (asymmetric routing where the return traffic bypasses the ION).
If the flow had been denied by the ION's own firewall (Option C), the state would typically show as DENY or REJECT. If the handshake completed (Option A), the state would be ESTABLISHED. Therefore, INIT points to a lack of response from the remote end.

75. Frage
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.)

A. Syslog
B. LLDP
C. SNMP
D. CDP

Antwort: A,C

Begründung:
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.

76. Frage
An administrator is configuring an ION 2000 device for a deployment where high availability is required, but the site has only a single internet circuit. The administrator configures a Bypass Pair (Fail-to-Wire) on ports 1 and 2 connecting the ISP modem to the legacy firewall.
If the ION device loses power, what is the resulting behavior of the traffic flowing through this Bypass Pair?

A. Traffic is blocked to prevent uninspected packets from entering the network (Fail-to-Block).
B. The device reboots into "Safe Mode" and acts as a Layer 2 switch.
C. The internal relay closes, physically bridging Port 1 and Port 2, allowing traffic to flow transparently between the modem and firewall.
D. Traffic is rerouted to the LTE modem automatically.

Antwort: C

Begründung:
Comprehensive and Detailed Explanation
The Bypass Pair feature on Prisma SD-WAN ION devices (specifically supported models like ION 2000, 3000, 7000, 9000) is a hardware-based resiliency mechanism known as Fail-to-Wire.
Operation: A "Bypass Pair" logically groups two physical interfaces (e.g., WAN 1 and LAN 1). Under normal operation, the ION processes traffic between them.
Power Loss: In the event of a total power loss (or critical software failure), a mechanical relay inside the device physically closes the circuit between the two ports.
Result: This creates a direct electrical connection (like a patch cable) between the upstream device (ISP Modem) and the downstream device (Legacy Firewall or Router). This ensures that internet connectivity is preserved for the site, even if the SD-WAN appliance is completely dead. This is critical for single-point-of-failure deployments where maintaining basic dial-tone is more important than SD-WAN optimization during a hardware outage.
