Palo Alto Networks SD-WAN Engineer SD-WAN-Engineer Prüfungsfragen mit Lösungen (Q65-Q70):

65. Frage
For how many hours are Prisma SD-WAN VPN shared secrets valid?

A. 0
B. 1
C. 2
D. 3

Antwort: D

Begründung:
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.

66. Frage
By default, how many days will Prisma SD-WAN VPNs stay operational before the keys expire when an ION device loses connection with the controller?

A. 0
B. 1
C. 2
D. 3

Antwort: D

Begründung:
Comprehensive and Detailed Explanation
The Prisma SD-WAN (CloudGenix) solution is designed with a separation of the control plane (Controller) and the data plane (ION devices).1 In the event that an ION device loses connectivity to the Cloud Controller (often referred to as running in "headless mode"), the device continues to forward traffic and maintain existing VPN tunnels using the keys it currently holds.2 However, for security purposes, the VPN session keys (shared secrets) used for the Secure Fabric have a finite validity period. The system is designed such that these keys are rotated regularly.3 If the controller is unreachable, the ION device can continue to rotate keys locally and maintain the VPNs for a maximum default period of 72 hours (exactly 3 days).4 If the connection to the controller is not restored within this 72-hour window, the keys will eventually expire, and the ION will be unable to retrieve new authorized key material from the controller.5 Consequently, the VPN tunnels will go down, and the "out of shared secret key" error will be observed in the VPN status logs.
This mechanism ensures that a permanently compromised or stolen device cannot maintain network access indefinitely without central authorization.

67. Frage
A network engineer is troubleshooting a "Voice Quality" issue. They suspect that the DSCP markings are being stripped or altered by the ISP.
Which tool in the Prisma SD-WAN portal allows the engineer to capture live packets on the WAN interface and inspect the IP header ToS/DSCP field?

A. Event Logs
B. Path Quality Monitor
C. Packet Capture (PCAP)
D. Flow Browser

Antwort: C

Begründung:
Comprehensive and Detailed Explanation
To validate specific packet-level details like DSCP (Differentiated Services Code Point) values, header checksums, or exact payload sizes, a Packet Capture (PCAP) is required.
PCAP Tool: Prisma SD-WAN provides a built-in PCAP utility accessible directly from the portal. The engineer can select the specific Interface (e.g., Internet 1), apply a Filter (e.g., port 5060 or host 1.2.3.4), and capture the traffic.
Analysis: The resulting .pcap file can be downloaded and opened in Wireshark. This allows the engineer to definitively see if the packets leaving the ION have DSCP EF (46) and if the packets arriving (if capturing on the other side) still retain that marking, or if the ISP has bleached it to CS0 (0).
Flow Browser (A): While it shows "Application" and metrics, the Flow Browser typically displays the assigned priority class, not necessarily the raw bit-level DSCP value present in the packet header on the wire.

68. Frage
An administrator needs to generate a monthly report showing the "Top Applications" by bandwidth usage across all branch sites to justify a bandwidth upgrade.
Which specific component of the Prisma SD-WAN interface is designed to create, schedule, and email these PDF summaries?

A. Media Analytics
B. Flow Browser
C. Activity Charts
D. Reports

Antwort: D

Begründung:
Comprehensive and Detailed Explanation
Prisma SD-WAN separates real-time visibility from historical summarization.
* Reports (C): The Reports section is the dedicated engine for generating historical summaries.
Administrators can create custom report templates (e.g., "Monthly Executive Summary") that include specific widgets like "Top Applications by Volume," "Site Availability," or "Circuit Utilization." Crucially, this feature allows for Scheduling, where the system automatically generates the PDF report at a set interval (e.g., first day of the month) and emails it to a distribution list.
* Activity Charts (A) / Media Analytics (B): These provide interactive, visual graphs for ad-hoc analysis but are not designed for generating downloadable, scheduled PDF summaries for management.
* Flow Browser (D): This is for deep-dive troubleshooting of individual sessions, not for high-level aggregate reporting.

69. Frage
When integrating Prisma SD-WAN with Prisma Access, what is the specific role of the Service Connection (SC)?

A. It connects the Prisma Access cloud infrastructure back to the customer's Headquarters or Data Center for access to internal private resources (e.g., AD, DNS, Intranet).
B. It is the IPSec tunnel that connects a Branch site to the Prisma Access gateway for internet access.
C. It is the peering link between different Prisma Access regions to optimize global traffic.
D. It is the SSL VPN portal used by mobile users to connect to the network.

Antwort: A

Begründung:
Comprehensive and Detailed Explanation
In the Prisma Access architecture (integrated with SD-WAN), distinct connection types serve different purposes.
Remote Networks: These are the connections from your Branch sites (using ION devices) into the cloud. They allow branches to get to the internet or other branches.
Service Connections (SC): This is a specialized high-bandwidth connection used to bridge the Prisma Access Cloud to your Private Data Center or Headquarters.
The primary use case for a Service Connection (Option A) is to allow mobile users and branch users (who are connected to the Prisma cloud) to reach private, centralized resources that still reside on-premise, such as Active Directory controllers, legacy databases, or mainframes. Without a Service Connection, users in the cloud would be able to reach the internet and each other, but not the servers physically located in your HQ data center. The CloudBlade automates the creation of these tunnels, but architecturally, the "Service Connection" is the "cloud-to-HQ" bridge.
