NEW QUESTION # 18
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?
Answer: B
Explanation:
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.
NEW QUESTION # 19
In a Prisma SD-WAN deployment, what is the defining characteristic of a "Standard VPN" compared to a
"Secure Fabric Link"?
Answer: A
Explanation:
Comprehensive and Detailed Explanation
In the Prisma SD-WAN architecture, the terminology distinguishes between "Native" automation and
"Legacy" interoperability.
* Secure Fabric Links: These are the proprietary, automated overlay tunnels created between two Prisma SD-WAN ION devices (e.g., Branch ION to Data Center ION). The controller automatically manages the IP addressing, key rotation, and routing for these links. You do not manually configure
"Phase 1" or "Phase 2" parameters for Secure Fabric links.
* Standard VPNs: These are traditional, standards-based IPSec tunnels configured to connect an ION device to a Non-ION endpoint (Third-Party Peer). This is used for "Data Center to Data Center" connections where one side is a legacy firewall (e.g., Cisco ASA, Palo Alto Networks NGFW) or for connecting to cloud security services (SSE) that do not have a specific CloudBlade integration. For a Standard VPN, the administrator must manually define the IKE/IPSec profiles, pre-shared keys, and peer IP addresses to match the third-party device's configuration.
NEW QUESTION # 20
Site templates are to be used for the large-scale deployment of 100 Prisma SD-WAN branch sites across different regions.
Which two statements align with the capabilities and best practices for Prisma SD-WAN site templates?
(Choose two.)
Answer: B,D
Explanation:
Comprehensive and Detailed Explanation
Site Templates (often referred to as Site Configuration Templates) are a critical tool for the Zero Touch Provisioning (ZTP) of large-scale deployments in Prisma SD-WAN.
1. Device Pre-staging (Statement C):
One of the primary capabilities of Site Templates is the creation of Device Shells. A device shell is a configuration container that exists in the controller before the physical hardware is installed or connected. By using a template, an administrator can pre-provision the entire configuration (interfaces, routing, subnets) for the "Site" and "Element" (Device). When the physical ION device is later connected to the internet and claimed (associated with the shell via its Serial Number), it immediately inherits this pre-staged configuration, enabling a true "plug-and-play" deployment.
2. Mandatory Variables (Statement B):
To successfully instantiate a functional site from a generic template, specific unique identifiers are required in the variable data set (typically a CSV file).
* Site Name: Identifies the location in the portal.
* ION Software Version: Ensures the device boots to the specific validated code version required for the deployment, preventing inconsistencies.
* ION Serial Number / Device Name: Required to bind the logical configuration (Shell) to the physical hardware. Even if the serial is added later during the claim process, the structure of the template and the deployment workflow mandates these variables to ensure the device can be uniquely identified and managed within the fabric.
Note on Option D: While it is technically possible to re-deploy a template, the Best Practice for "Day 2" operations (updating or modifying configuration after deployment) is to use Prisma SD-WAN Stacks (Network Stacks, Security Stacks, etc.). Stacks allow for granular, policy-based updates across multiple sites without the destructive or rigid nature of re-applying a full site initialization template. Therefore, D is not the aligned best practice.
NEW QUESTION # 21
An engineer at a managed services provider is updating an application that allows its customers to request firewall changes to also manage SD-WAN. The application will be able to make any approved changes directly to devices via API.
What is a requirement for the application to create SD-WAN interfaces?
Answer: C
Explanation:
In Palo Alto Networks PAN-OS SD-WAN environments, automation and orchestration are key components for service providers managing large-scale deployments. The PAN-OS REST API provides a modern, structured way to programmatically manage configuration objects, including those required for SD-WAN functionality.
When an application is designed to push changes directly to devices (individual firewalls) rather than through a centralized template in Panorama, it must interact with the firewall's local REST API. To successfully create a virtual SD-WAN interface, the application must target the correct resource URI. In the PAN-OS API schema, the logical SD-WAN interface-which groups physical links to enable application-based path selection-is managed via the sdwanInterfaces parameter within the REST API.
It is important to distinguish between the interface itself and the profiles that support it. Option A refers to sdwanInterfaceprofiles, which are the objects used to define the characteristics of a link (such as bandwidth, link type, and monitoring frequency), but not the interface itself. Furthermore, since the scenario specifies making changes "directly to devices," the target must be the firewall rather than Panorama. While Panorama can manage these objects via templates, a direct-to-device automation workflow necessitates using the firewall's REST API endpoint. Utilizing the REST API over the legacy XML API is the recommended standard for modern integrations due to its ease of use with JSON payloads and alignment with contemporary DevSecOps practices. By using the sdwanInterfaces parameter on the firewall, the MSP application can programmatically bind physical Layer 3 interfaces to the SD-WAN fabric.
NEW QUESTION # 22
When integrating Prisma SD-WAN with Prisma Access, what is the specific role of the Service Connection (SC)?
Answer: C
Explanation:
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.
