Question 81<\/b><\/h3>\n

What is the main purpose of onboarding an ION device into the Prisma SD-WAN environment?<\/b><\/p>\n

    \n
  1. To create local DNS records<\/span><\/li>\n
  2. To establish the device as a managed SD-WAN component<\/span><\/li>\n
  3. To replace every branch router<\/span><\/li>\n
  4. To disable centralized management<\/span><\/li>\n<\/ol>\n

    Correct Answer: 2<\/b><\/p>\n

    Explanation<\/b><\/p>\n

    Onboarding an ION device establishes it as a managed component of the Prisma SD-WAN environment. During onboarding, the device is associated with the appropriate tenant and site configuration so that centralized management can recognize and control it. Once successfully onboarded and connected, the ION device can receive configuration and policy information and report operational information back to the controller infrastructure. Onboarding is therefore more than simply connecting a physical appliance to a network. It is an essential step that establishes the relationship between the deployed device, its site, and centralized Prisma SD-WAN management.<\/span><\/p>\n

    Question 82<\/b><\/h3>\n

    Which information is most important when associating an ION device with the intended Prisma SD-WAN site?<\/b><\/p>\n

      \n
    1. The site’s identity and device association<\/span><\/li>\n
    2. The browser version<\/span><\/li>\n
    3. The user’s desktop wallpaper<\/span><\/li>\n
    4. The application font<\/span><\/li>\n<\/ol>\n

      Correct Answer: 1<\/b><\/p>\n

      Explanation<\/b><\/p>\n

      The intended site and device association is important because Prisma SD-WAN applies configuration and policy according to the logical site where an ION device operates. Associating a device with the wrong site can result in incorrect interfaces, policies, routing information, or other configuration being applied. Site identity provides the administrative context in which the ION device operates. Browser settings and unrelated endpoint characteristics do not determine the SD-WAN site’s configuration. During onboarding, administrators should carefully verify the device identity and its intended site assignment before applying production configuration.<\/span><\/p>\n

      Question 83<\/b><\/h3>\n

      An ION device is powered on but cannot establish communication with the Prisma SD-WAN controller. Which area should be investigated first?<\/b><\/p>\n

        \n
      1. Application QoS classes<\/span><\/li>\n
      2. Controller connectivity<\/span><\/li>\n
      3. Destination NAT rules<\/span><\/li>\n
      4. User groups<\/span><\/li>\n<\/ol>\n

        Correct Answer: 2<\/b><\/p>\n

        Explanation<\/b><\/p>\n

        When an ION device cannot establish communication with the Prisma SD-WAN controller, controller connectivity should be investigated first. The device needs appropriate network reachability and communication with the controller infrastructure to participate in centralized management. Administrators should verify the relevant interfaces, addressing, routing, upstream connectivity, and any security controls that could prevent controller communication. Application QoS and user-group configuration are unlikely to explain an initial controller connection failure. NAT rules may matter in some environments, but the first troubleshooting focus should remain on whether the ION device can reach the required controller services.<\/span><\/p>\n

        Question 84<\/b><\/h3>\n

        Why should an administrator verify the correct software version before deploying an ION device into production?<\/b><\/p>\n

          \n
        1. To ensure compatibility with the supported deployment environment<\/span><\/li>\n
        2. To increase the number of users automatically<\/span><\/li>\n
        3. To remove all security policies<\/span><\/li>\n
        4. To prevent controller communication<\/span><\/li>\n<\/ol>\n

          Correct Answer: 1<\/b><\/p>\n

          Explanation<\/b><\/p>\n

          Verifying the software version before production deployment helps ensure that the ION device operates with a supported and compatible software release. Version compatibility can affect available features, controller interaction, policy behavior, and interoperability with other Prisma SD-WAN components. Deploying an unsupported or inappropriate release can introduce unexpected behavior or limit access to required functionality. Software version verification should therefore be part of deployment preparation rather than an activity performed only after a problem occurs. Administrators should follow the supported release requirements and upgrade procedures applicable to their Prisma SD-WAN environment.<\/span><\/p>\n

          Question 85<\/b><\/h3>\n

          A branch has two WAN circuits. The administrator wants traffic to use the second circuit when the first circuit no longer satisfies application requirements. What SD-WAN capability supports this behavior?<\/b><\/p>\n

            \n
          1. Application-aware path selection<\/span><\/li>\n
          2. Static DNS registration<\/span><\/li>\n
          3. User authentication<\/span><\/li>\n
          4. Destination NAT<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation<\/b><\/p>\n

            Application-aware path selection allows Prisma SD-WAN to select an appropriate WAN path based on application requirements and measured network conditions. If the preferred circuit no longer satisfies the configured performance criteria, the system can select another available path when policy permits. This approach differs from simple static routing because the decision can consider application performance and link quality. DNS registration, authentication, and destination NAT serve different networking functions. Application-aware path selection is therefore central to SD-WAN environments where traffic should dynamically use suitable WAN resources according to changing network conditions.<\/span><\/p>\n

            Question 86<\/b><\/h3>\n

            Which component provides centralized control and management for deployed Prisma SD-WAN ION devices?<\/b><\/p>\n

              \n
            1. Branch switch<\/span><\/li>\n
            2. Prisma SD-WAN controller infrastructure<\/span><\/li>\n
            3. Local DHCP server<\/span><\/li>\n
            4. Endpoint operating system<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation<\/b><\/p>\n

              Prisma SD-WAN controller infrastructure provides centralized management and control for deployed ION devices. It allows administrators to define and distribute configuration, policies, and other operational settings from a centralized environment rather than manually configuring every branch device independently. The ION devices still perform local forwarding and traffic-processing functions at their respective sites. A branch switch, DHCP server, or endpoint operating system may support local network operations, but none serves as the centralized SD-WAN management platform. This separation between centralized control and distributed forwarding is a fundamental concept in Prisma SD-WAN architecture.<\/span><\/p>\n

              Question 87<\/b><\/h3>\n

              A network engineer needs to replace a failed ION device at a branch. What should be verified before placing the replacement into service?<\/b><\/p>\n

                \n
              1. Correct device identity and intended site assignment<\/span><\/li>\n
              2. Unrelated endpoint browser settings<\/span><\/li>\n
              3. User desktop resolution<\/span><\/li>\n
              4. Application window size<\/span><\/li>\n<\/ol>\n

                Correct Answer: 1<\/b><\/p>\n

                Explanation<\/b><\/p>\n

                When replacing an ION device, the administrator should verify that the replacement device is correctly identified and associated with the intended branch site. Proper device and site association ensures that the correct configuration, policies, interfaces, and other site-specific settings are applied. A replacement process should also include verification of connectivity and operational status before production traffic is restored. Endpoint display settings and application window characteristics are unrelated to ION replacement. Careful identity and site verification helps prevent a replacement device from being unintentionally deployed with configuration belonging to another location.<\/span><\/p>\n

                Question 88<\/b><\/h3>\n

                Which troubleshooting approach is most appropriate when an overlay tunnel is not forming between two Prisma SD-WAN sites?<\/b><\/p>\n

                  \n
                1. Verify underlay connectivity and required controller or tunnel communication<\/span><\/li>\n
                2. Change application names<\/span><\/li>\n
                3. Remove all QoS policies<\/span><\/li>\n
                4. Increase endpoint screen resolution<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 1<\/b><\/p>\n

                  Explanation<\/b><\/p>\n

                  An overlay tunnel depends on underlying network connectivity and the required control or tunnel communication between participating components. When a tunnel does not form, administrators should first verify that the relevant WAN interfaces are operational and that the required network reachability exists. They should also examine tunnel and controller status for indications of communication or configuration problems. Changing application names or removing unrelated QoS policies does not address the fundamental connectivity requirements of tunnel establishment. A structured troubleshooting process should begin with the underlay and then move toward overlay configuration and status.<\/span><\/p>\n

                  Question 89<\/b><\/h3>\n

                  Which routing protocol can be used to exchange routes dynamically in an enterprise network when supported by the Prisma SD-WAN deployment?<\/b><\/p>\n

                    \n
                  1. FTP<\/span><\/li>\n
                  2. SMTP<\/span><\/li>\n
                  3. BGP<\/span><\/li>\n
                  4. SNMP<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 3<\/b><\/p>\n

                    Explanation<\/b><\/p>\n

                    BGP, or Border Gateway Protocol, is a routing protocol used to exchange reachability information between routing domains and can be used in supported enterprise Prisma SD-WAN deployments. Dynamic routing can reduce the need to maintain large numbers of manually configured static routes and can help networks respond to topology changes. FTP is used for file transfer, SMTP handles email delivery, and SNMP is primarily used for network monitoring and management. When integrating dynamic routing with SD-WAN, administrators should understand how learned routes interact with local forwarding, policy decisions, and the overall branch routing design.<\/span><\/p>\n

                    Question 90<\/b><\/h3>\n

                    What is a major benefit of using dynamic routing instead of maintaining every route manually?<\/b><\/p>\n

                      \n
                    1. It can adapt route information as network topology changes<\/span><\/li>\n
                    2. It eliminates all security policies<\/span><\/li>\n
                    3. It prevents WAN failures<\/span><\/li>\n
                    4. It removes the need for interfaces<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 1<\/b><\/p>\n

                      Explanation<\/b><\/p>\n

                      Dynamic routing protocols can automatically exchange and update route information as network topology changes. This reduces the administrative effort required to maintain large collections of static routes and can improve responsiveness when networks change. Dynamic routing does not prevent physical WAN failures, eliminate security policies, or remove the need for interfaces. Instead, it provides a mechanism for exchanging reachability information between routing participants. In an SD-WAN environment, dynamic routing should be designed alongside path selection, overlays, and security policies so that learned routes produce predictable forwarding behavior across branch and data-center networks.<\/span><\/p>\n

                      Question 91<\/b><\/h3>\n

                      Why might an administrator use route redistribution in an SD-WAN environment?<\/b><\/p>\n

                        \n
                      1. To exchange routes between different routing sources<\/span><\/li>\n
                      2. To encrypt every packet individually<\/span><\/li>\n
                      3. To assign usernames to applications<\/span><\/li>\n
                      4. To change DSCP markings<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1<\/b><\/p>\n

                        Explanation<\/b><\/p>\n

                        Route redistribution allows routes learned from one routing source or protocol to be introduced into another routing domain or routing process. This can be useful when an enterprise network uses different routing mechanisms in different portions of the infrastructure. For example, routes learned through one routing protocol may need to become available to another routing process. Redistribution must be designed carefully because uncontrolled redistribution can create routing loops, duplicate routes, or unexpected path selection. It is therefore important to apply appropriate route policies and understand the direction and scope of redistributed information.<\/span><\/p>\n

                        Question 92<\/b><\/h3>\n

                        A route is present in the routing table, but traffic still does not reach the destination. What should the administrator remember?<\/b><\/p>\n

                          \n
                        1. A routing entry alone does not guarantee successful end-to-end forwarding<\/span><\/li>\n
                        2. The route automatically bypasses security policies<\/span><\/li>\n
                        3. NAT always occurs<\/span><\/li>\n
                        4. QoS removes the route<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 1<\/b><\/p>\n

                          Explanation<\/b><\/p>\n

                          The presence of a route in a routing table confirms that the device has a forwarding entry, but it does not guarantee successful end-to-end communication. Traffic can still fail because of interface problems, next-hop reachability, security policies, NAT behavior, tunnel problems, return-path issues, or application-specific conditions. Administrators should therefore troubleshoot the entire forwarding path rather than stopping after confirming a route exists. In Prisma SD-WAN environments, routing, policy processing, path selection, and overlay behavior work together. Successful connectivity requires these components to produce compatible forwarding decisions.<\/span><\/p>\n

                          Question 93<\/b><\/h3>\n

                          Which configuration concept allows a common policy to be applied while still supporting site-specific policy differences?<\/b><\/p>\n

                            \n
                          1. Policy stacking<\/span><\/li>\n
                          2. Local screen scaling<\/span><\/li>\n
                          3. Browser caching<\/span><\/li>\n
                          4. Endpoint compression<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1<\/b><\/p>\n

                            Explanation<\/b><\/p>\n

                            Policy stacking allows administrators to organize policy configurations into reusable layers so that common behavior can be applied broadly while additional rules or exceptions can be introduced where required. This approach is useful in large SD-WAN environments because different branches may share baseline requirements while still needing location-specific controls. Instead of independently recreating every policy at every site, administrators can use a structured policy hierarchy. Proper ordering and inheritance are important because multiple layers can influence the final effective configuration. Policy stacking therefore supports centralized consistency while accommodating controlled local differences.<\/span><\/p>\n

                            Question 94<\/b><\/h3>\n

                            What is an important reason to bind a policy stack to the appropriate site?<\/b><\/p>\n

                              \n
                            1. To ensure the intended site receives the configured policy<\/span><\/li>\n
                            2. To change the device’s physical serial number<\/span><\/li>\n
                            3. To disable all routing<\/span><\/li>\n
                            4. To remove WAN circuits<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 1<\/b><\/p>\n

                              Explanation<\/b><\/p>\n

                              Binding a policy stack to the appropriate site ensures that the intended configuration is applied to the correct deployment location. In a centralized SD-WAN environment, administrators may manage policies for many branches, so site association is essential for maintaining configuration accuracy. Applying a stack to the wrong site could unintentionally change traffic handling, security controls, NAT behavior, QoS treatment, or application performance policies at another location. Careful binding therefore helps maintain predictable deployment behavior. Site assignment and policy binding should be reviewed whenever a new branch is created or an existing site configuration is modified.<\/span><\/p>\n

                              Question 95<\/b><\/h3>\n

                              An administrator changes a centralized policy but does not observe the expected behavior at a branch. Which area should be checked first?<\/b><\/p>\n

                                \n
                              1. Whether the updated configuration was successfully deployed to the site<\/span><\/li>\n
                              2. Whether the user’s monitor is working<\/span><\/li>\n
                              3. Whether the application icon changed<\/span><\/li>\n
                              4. Whether the keyboard layout is correct<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 1<\/b><\/p>\n

                                Explanation<\/b><\/p>\n

                                When a centralized policy change does not produce the expected branch behavior, the administrator should verify that the updated configuration was successfully deployed and applied to the intended site. Centralized management separates policy definition from actual device operation, so a configuration change must reach the relevant ION device before it can affect traffic. Administrators should check deployment or configuration status and then confirm the effective policy on the affected site. Unrelated endpoint characteristics do not determine whether the SD-WAN policy was successfully distributed. Deployment verification is therefore a key troubleshooting step.<\/span><\/p>\n

                                Question 96<\/b><\/h3>\n

                                Which interface-related configuration is most important when an ION device must forward traffic through a particular WAN circuit?<\/b><\/p>\n

                                  \n
                                1. Correct interface and circuit configuration<\/span><\/li>\n
                                2. Desktop wallpaper settings<\/span><\/li>\n
                                3. User email signature<\/span><\/li>\n
                                4. Browser bookmark configuration<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 1<\/b><\/p>\n

                                  Explanation<\/b><\/p>\n

                                  Correct interface and circuit configuration is essential when an ION device must forward traffic through a specific WAN connection. The interface identifies the network connection available to the device, while circuit configuration provides the logical context needed for WAN operation and path selection. Incorrect addressing, administrative state, circuit type, or related parameters can prevent the circuit from being usable even when the physical cable is connected. Endpoint personalization settings have no role in WAN forwarding. Administrators should verify interface and circuit status whenever a path is unavailable, incorrectly selected, or behaving differently from the expected configuration.<\/span><\/p>\n

                                  Question 97<\/b><\/h3>\n

                                  Which capability helps Prisma SD-WAN determine whether an application should remain on its current network path?<\/b><\/p>\n

                                    \n
                                  1. Application and link performance measurements<\/span><\/li>\n
                                  2. Keyboard input language<\/span><\/li>\n
                                  3. Desktop screen size<\/span><\/li>\n
                                  4. User wallpaper<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1<\/b><\/p>\n

                                    Explanation<\/b><\/p>\n

                                    Application and link performance measurements provide the information Prisma SD-WAN can use to evaluate whether a current path continues to satisfy configured requirements. Link measurements can include characteristics such as latency, loss, and jitter, while application measurements can provide information about actual application behavior. Considering both levels of information can help distinguish a healthy transport from a path that is technically reachable but unsuitable for a particular application. Endpoint personalization settings do not contribute to path evaluation. This combination of measurements supports more informed application-aware traffic decisions in changing WAN conditions.<\/span><\/p>\n

                                    Question 98<\/b><\/h3>\n

                                    A voice application experiences high delay on its active WAN circuit, while another circuit meets the configured requirements. What should the SD-WAN system be able to do when policy permits?<\/b><\/p>\n

                                    1. Keep voice traffic on the degraded path regardless of measurements<\/span><\/li>\n
                                    2. Move the traffic toward a suitable alternative path<\/span><\/li>\n
                                    3. Disable all voice traffic permanently<\/span><\/li>\n
                                    4. Remove the application’s policy<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 2<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      When a voice application’s active circuit develops excessive delay and another available circuit meets the configured performance requirements, Prisma SD-WAN can move traffic toward the suitable alternative when the applicable policy allows this behavior. Application-aware path selection uses measured conditions and configured requirements to determine whether a path remains appropriate. This is particularly valuable for voice because excessive delay can affect conversation quality. The system does not need to permanently disable the application or remove its policy. Instead, path-management capabilities can help maintain service by selecting a better-performing transport.<\/span><\/p>\n

                                      What should an administrator inspect when an ION device reports that a WAN link is down unexpectedly?<\/b><\/p>\n

                                        \n
                                      1. Interface state and physical or upstream connectivity<\/span><\/li>\n
                                      2. Application icon color<\/span><\/li>\n
                                      3. User password complexity<\/span><\/li>\n
                                      4. Browser history<\/span><\/li>\n<\/ol>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        Explanation<\/b><\/p>\n

                                        When a WAN link unexpectedly reports a down state, the administrator should inspect the interface state and the physical or upstream connectivity supporting that circuit. This includes checking whether the interface is administratively enabled, whether the connected equipment is functioning, and whether the upstream provider or network is reachable. A WAN circuit can become unavailable because of local interface problems, cabling, provider outages, or configuration errors. Application icons, passwords, and browser history are unrelated to basic circuit status. Starting with the interface and underlying connectivity provides a logical foundation for further SD-WAN troubleshooting.<\/span><\/p>\n

                                        Question 100<\/b><\/h3>\n

                                        Which design principle is most important when deploying multiple WAN transports for application-aware SD-WAN?<\/b><\/p>\n

                                          \n
                                        1. Every application must use the same circuit<\/span><\/li>\n
                                        2. All traffic should bypass policy decisions<\/span><\/li>\n
                                        3. WAN transports should provide usable alternatives according to policy and performance requirements<\/span><\/li>\n
                                        4. Only the fastest circuit should ever be configured<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 3<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          Application-aware SD-WAN is most effective when multiple WAN transports provide meaningful alternatives that can be selected according to policy and application performance requirements. Different circuits may have different characteristics, including latency, loss, jitter, bandwidth, cost, or availability. Prisma SD-WAN can use these conditions when determining appropriate paths for applications. Requiring every application to use one circuit would reduce the flexibility of SD-WAN path selection, while bypassing policy would remove centralized control. A well-designed deployment therefore combines diverse transports with clear application requirements and policies that define acceptable path behavior.<\/span><\/p>\n
