Question 1<\/b><\/h3>\n

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

    \n
  1. Prisma SD-WAN Controller<\/span><\/li>\n
  2. Branch LAN switch<\/span><\/li>\n
  3. Internet gateway<\/span><\/li>\n
  4. Client endpoint<\/span><\/li>\n<\/ol>\n

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

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

    The Prisma SD-WAN Controller provides centralized management and control for deployed ION devices. It enables administrators to configure policies, manage sites, distribute configurations, and obtain centralized visibility into the SD-WAN environment. ION devices perform forwarding and local policy enforcement while communicating with the controller. This centralized architecture helps organizations manage many branch locations consistently instead of configuring every branch independently. The controller-based model is a core part of Prisma SD-WAN’s operational architecture and supports centralized application-aware traffic management across distributed WAN environments.<\/span><\/p>\n

    Question 2<\/b><\/h3>\n

    A branch ION device must actively select application paths and enforce QoS policies. Which Prisma SD-WAN operating mode should be used?<\/b><\/p>\n

      \n
    1. Analytics<\/span><\/li>\n
    2. Control<\/span><\/li>\n
    3. Disabled<\/span><\/li>\n
    4. Monitoring-only<\/span><\/li>\n<\/ol>\n

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

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

      Control mode enables the branch ION device to participate actively in traffic forwarding and policy enforcement. In this mode, the ION device can select available paths for applications and apply security and Quality of Service policies. Analytics mode primarily observes traffic and provides visibility without making application path-selection decisions, while Disabled mode does not perform policy-based application forwarding. Therefore, when the requirement is active traffic steering combined with policy enforcement, Control mode satisfies the operational requirement. Palo Alto Networks documentation specifically distinguishes these three operating modes by their forwarding and policy capabilities.<\/span><\/p>\n

      Question 3<\/b><\/h3>\n

      What is the primary purpose of a Prisma SD-WAN path policy?<\/b><\/p>\n

        \n
      1. Assign IP addresses to clients<\/span><\/li>\n
      2. Define DNS forwarding behavior<\/span><\/li>\n
      3. Determine network paths for application sessions<\/span><\/li>\n
      4. Encrypt all endpoint storage<\/span><\/li>\n<\/ol>\n

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

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

        A Prisma SD-WAN path policy defines which network paths application sessions should use. Policy rules can consider attributes such as applications, prefixes, network contexts, users or groups, and device information. The policy can identify active, backup, and Layer 3 failure paths and can use SLA-based or best-path selection methods. This allows the SD-WAN environment to make application-aware forwarding decisions rather than relying only on traditional destination-based routing. Path policies therefore form an important part of traffic engineering and dynamic WAN path selection in Prisma SD-WAN.<\/span><\/p>\n

        Question 4<\/b><\/h3>\n

        An administrator wants voice traffic to use a path only when latency, loss, and jitter remain within defined thresholds. Which path-selection approach directly supports this requirement?<\/b><\/p>\n

          \n
        1. Static routing<\/span><\/li>\n
        2. Random path selection<\/span><\/li>\n
        3. Destination-only forwarding<\/span><\/li>\n
        4. SLA-compliant path selection<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4<\/b><\/p>\n

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

          SLA-compliant path selection evaluates defined performance metrics before selecting a path for application traffic. Prisma SD-WAN can evaluate metrics such as latency, packet loss, jitter, and MOS, along with applicable probe and application measurements. When an active path no longer satisfies the configured SLA requirements, the policy can move traffic toward an eligible backup path. This approach is particularly useful for applications such as voice and video because their performance depends on measurable network quality rather than simple reachability. It allows path selection to reflect application performance requirements.<\/span><\/p>\n

          Question 5<\/b><\/h3>\n

          Which component sits in the traffic path at a Prisma SD-WAN branch and performs local forwarding decisions?<\/b><\/p>\n

            \n
          1. ION device<\/span><\/li>\n
          2. Cloud Identity Engine<\/span><\/li>\n
          3. Management browser<\/span><\/li>\n
          4. DNS resolver<\/span><\/li>\n<\/ol>\n

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

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

            The ION device is the branch-side component that participates directly in traffic processing. Depending on its operating mode and configuration, it can monitor application flows, forward traffic, select paths, and enforce policies. The ION device communicates with the centralized Prisma SD-WAN management infrastructure while making local decisions for traffic traversing the branch. This distributed processing model allows application-aware forwarding to occur close to users and applications while still benefiting from centralized policy management and visibility. ION devices are therefore fundamental components of Prisma SD-WAN branch deployments.<\/span><\/p>\n

            Question 6<\/b><\/h3>\n

            A company wants different path policies for corporate applications and general Internet traffic. Which policy capability is most appropriate?<\/b><\/p>\n

              \n
            1. Single default route<\/span><\/li>\n
            2. Application-aware policy matching<\/span><\/li>\n
            3. Static NAT only<\/span><\/li>\n
            4. Physical interface shutdown<\/span><\/li>\n<\/ol>\n

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

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

              Prisma SD-WAN policies can use application identification as a matching criterion, allowing administrators to create different forwarding behavior for different applications. For example, business-critical applications can receive preferred paths while general Internet traffic can follow separate forwarding requirements. Application identification is central to Prisma SD-WAN because ION devices analyze flows and use application information for path selection, QoS, and security policies. This approach provides much more granular traffic engineering than applying identical forwarding behavior to every destination or interface.<\/span><\/p>\n

              Question 7<\/b><\/h3>\n

              In a Prisma SD-WAN path policy, what is the purpose of a backup path?<\/b><\/p>\n

                \n
              1. To replace the controller permanently<\/span><\/li>\n
              2. To provide an alternate route when the primary path is poor or unavailable<\/span><\/li>\n
              3. To disable application identification<\/span><\/li>\n
              4. To assign a new subnet<\/span><\/li>\n<\/ol>\n

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

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

                A backup path provides an alternate forwarding option when the configured active path is poor or unavailable. Prisma SD-WAN path policies can define active, backup, and Layer 3 failure paths so that traffic has progressively different forwarding options. Backup paths are considered after eligible active paths are no longer usable according to the policy’s conditions. This mechanism supports resilient application delivery across multiple WAN connections. It is different from the Layer 3 failure path, which is reserved for situations involving complete loss of Layer 3 reachability across the available links.<\/span><\/p>\n

                Question 8<\/b><\/h3>\n

                Which Prisma SD-WAN policy type is specifically designed to prioritize business traffic and allocate network resources according to application requirements?<\/b><\/p>\n

                  \n
                1. NAT policy<\/span><\/li>\n
                2. Security policy<\/span><\/li>\n
                3. QoS policy<\/span><\/li>\n
                4. Device inventory policy<\/span><\/li>\n<\/ol>\n

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

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

                  Quality of Service policies are designed to define business priority and traffic treatment for applications. In Prisma SD-WAN’s stacked policy architecture, QoS policy sets work alongside path policy sets. Path policies focus on traffic engineering and selecting network paths, while QoS policies address business priority and resource treatment. This separation allows administrators to independently define where traffic should travel and how traffic should be prioritized. Such policy organization helps support application performance requirements when multiple applications compete for limited WAN bandwidth.<\/span><\/p>\n

                  Question 9<\/b><\/h3>\n

                  What does Prisma SD-WAN use to identify application traffic for policy enforcement?<\/b><\/p>\n

                    \n
                  1. Application definitions and fingerprinting techniques<\/span><\/li>\n
                  2. Only destination MAC addresses<\/span><\/li>\n
                  3. Only physical cable type<\/span><\/li>\n
                  4. Only DHCP lease duration<\/span><\/li>\n<\/ol>\n

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

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

                    Prisma SD-WAN uses application definitions and fingerprinting technologies to identify application flows. ION devices analyze traffic and use information such as prefixes, ports, signatures, and SaaS-related characteristics to classify flows. The resulting application identification can then be used by path, QoS, and security policies. This application-aware approach allows policies to operate at a more meaningful level than simply matching IP addresses. Palo Alto Networks documentation describes applications as a core element of Prisma SD-WAN because application classification supports performance, compliance, security, and optimized connectivity decisions.<\/span><\/p>\n

                    Question 10<\/b><\/h3>\n

                    Which statement describes Prisma SD-WAN stacked policies?<\/b><\/p>\n

                      \n
                    1. They are used only for DNS resolution<\/span><\/li>\n
                    2. They replace all ION devices<\/span><\/li>\n
                    3. They provide centrally defined policy layers for flow forwarding operations<\/span><\/li>\n
                    4. They operate only on endpoint operating systems<\/span><\/li>\n<\/ol>\n

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

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

                      Stacked policies provide a centralized policy framework for flow-forwarding operations in Prisma SD-WAN. The architecture supports stacked Path, QoS, Security, NAT, and Performance policies. Centrally defined policies are applied to ION devices, which then perform functions such as automatic path selection, traffic shaping, and active-active load balancing. Stacked policies also allow administrators to organize policy sets in a structured manner and reuse common policy definitions across sites. This architecture is important for maintaining consistent behavior across larger SD-WAN deployments.<\/span><\/p>\n

                      Question 11<\/b><\/h3>\n

                      An administrator needs to match traffic based on a specific source and destination network prefix before selecting a path. Which policy attributes can provide this match?<\/b><\/p>\n

                        \n
                      1. Prefixes<\/span><\/li>\n
                      2. Firmware images<\/span><\/li>\n
                      3. Hardware serial numbers only<\/span><\/li>\n
                      4. Browser cookies<\/span><\/li>\n<\/ol>\n

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

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

                        Prefixes can be used as matching criteria in Prisma SD-WAN path policy rules. Administrators can specify source and destination prefixes so that forwarding behavior applies to particular network ranges. Prefix matching can be combined with other criteria such as applications, network contexts, users, groups, and device profiles. This allows traffic engineering policies to become more specific for particular network flows. Prefix-based matching is especially useful when different applications or network segments require different forwarding treatment while sharing the same physical WAN infrastructure.<\/span><\/p>\n

                        Question 12<\/b><\/h3>\n

                        Which Prisma SD-WAN feature allows policies to be applied based on individual users or user groups?<\/b><\/p>\n

                          \n
                        1. Device replacement<\/span><\/li>\n
                        2. User-ID based policies<\/span><\/li>\n
                        3. Interface mirroring<\/span><\/li>\n
                        4. Static ARP<\/span><\/li>\n<\/ol>\n

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

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

                          Prisma SD-WAN supports User-ID based policies that allow administrators to include individual users or user groups in path, QoS, and security policy rules. User information can be obtained through integration involving PAN-OS firewalls and the Cloud Identity Engine, after which relevant mappings can be distributed to ION devices. This capability allows traffic policies to reflect user identity instead of relying solely on network addresses. It can therefore support more granular policy decisions for organizations that need differentiated treatment based on users or groups.<\/span><\/p>\n

                          Question 13<\/b><\/h3>\n

                          What is the highest priority explicit order value for a Prisma SD-WAN policy rule?<\/b><\/p>\n

                            \n
                          1. 65535<\/span><\/li>\n
                          2. 1024<\/span><\/li>\n
                          3. 100<\/span><\/li>\n
                          4. 1<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 4<\/b><\/p>\n

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

                            In Prisma SD-WAN policy rules, an explicit order of 1 represents the highest priority. Administrators can assign an order value between 1 and 65535, with the default order being 1024 when no specific order is entered. Explicit ordering is useful when administrators need predictable evaluation between multiple rules. If rules have the same explicit order, implicit ordering based on matching specificity can determine precedence. Understanding policy order is important because an earlier matching rule can influence which action is applied to a traffic flow.<\/span><\/p>\n

                            Question 14<\/b><\/h3>\n

                            A Prisma SD-WAN administrator wants to apply common policy rules to several sites while keeping site-specific exceptions possible. Which architecture supports this requirement?<\/b><\/p>\n

                              \n
                            1. Stacked policy sets<\/span><\/li>\n
                            2. Individual workstation routes<\/span><\/li>\n
                            3. Local browser settings<\/span><\/li>\n
                            4. DHCP reservations<\/span><\/li>\n<\/ol>\n

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

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

                              Stacked policy sets allow administrators to organize reusable policy definitions and apply them to designated sites. Common rules can be grouped into reusable policy sets, while more specific sets can contain site-specific or application-specific behavior. Prisma SD-WAN evaluates policy sets in their configured sequence and rules within each set according to their order. This structure allows organizations to maintain consistent enterprise-wide behavior while still providing exceptions where required. It is particularly useful in environments with many branches that share common security, path, or QoS requirements.<\/span><\/p>\n

                              Question 15<\/b><\/h3>\n

                              Which action causes matching traffic to be dropped without sending a TCP reset or ICMP host-unreachable message?<\/b><\/p>\n

                                \n
                              1. Allow<\/span><\/li>\n
                              2. Reject<\/span><\/li>\n
                              3. Deny<\/span><\/li>\n
                              4. Forward<\/span><\/li>\n<\/ol>\n

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

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

                                The Deny action drops traffic without sending a RESET or ICMP HOST UNREACHABLE message to the client or server. Reject behaves differently by actively rejecting matching traffic, including sending a RESET for applicable TCP traffic. Allow permits traffic that matches the rule. Understanding these actions is important when designing Prisma SD-WAN zone-based firewall policies because the selected action determines both whether traffic passes and how the endpoints experience the enforcement decision. Palo Alto Networks documents Allow, Deny, and Reject as supported security-policy actions.<\/span><\/p>\n

                                Question 16<\/b><\/h3>\n

                                What is the purpose of the L3 Failure Path in a Prisma SD-WAN path policy?<\/b><\/p>\n

                                  \n
                                1. It is always preferred over active paths<\/span><\/li>\n
                                2. It provides an emergency route after complete Layer 3 reachability failure<\/span><\/li>\n
                                3. It performs application classification<\/span><\/li>\n
                                4. It creates new security zones<\/span><\/li>\n<\/ol>\n

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

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

                                  The L3 Failure Path is intended as an ultimate emergency route when Layer 3 reachability has been completely lost across the available active and backup paths. It is not simply another preferred backup route. Prisma SD-WAN first considers eligible active paths and then backup paths according to policy conditions. The L3 Failure Path becomes relevant when those paths are completely down and Layer 3 reachability is unavailable. This distinction helps engineers design predictable failover behavior and prevents emergency paths from being selected prematurely during ordinary path degradation.<\/span><\/p>\n

                                  Question 17<\/b><\/h3>\n

                                  Which measurement can be used as part of SLA-based path selection for an application?<\/b><\/p>\n

                                    \n
                                  1. Link latency<\/span><\/li>\n
                                  2. Monitor brightness<\/span><\/li>\n
                                  3. CPU manufacturer<\/span><\/li>\n
                                  4. Keyboard layout<\/span><\/li>\n<\/ol>\n

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

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

                                    Latency is one of the network-quality measurements Prisma SD-WAN can use for SLA-compliant path selection. Other supported performance measurements can include packet loss, jitter, and MOS, depending on the policy and application requirements. Probe-based measurements and application metrics can also contribute to path evaluation. Using measurable network conditions allows the SD-WAN system to select paths according to application performance requirements rather than simply choosing an available interface. This is particularly valuable for real-time applications whose quality can deteriorate significantly when WAN performance changes.<\/span><\/p>\n

                                    Question 18<\/b><\/h3>\n

                                    A company uses a metered LTE circuit only for emergency connectivity. Which path-policy role is most appropriate for this circuit?<\/b><\/p>\n

                                      \n
                                    1. Primary active path for all applications<\/span><\/li>\n
                                    2. L3 failure path<\/span><\/li>\n

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

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

                                      A metered LTE circuit can be configured as an L3 failure path when the goal is to minimize its use while retaining emergency connectivity. Palo Alto Networks documentation describes using metered 3G\/4G\/LTE circuits as L3 failure paths so that they are considered only when normal forwarding options have failed at Layer 3. This design prevents ordinary application traffic from consuming expensive metered bandwidth unnecessarily. It provides a resilient last-resort option while preserving the primary WAN connections for normal business traffic.<\/span><\/p>\n

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

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

                                        Prisma SD-WAN security policies provide zone-based firewall enforcement for application traffic. Security rules can evaluate source and destination zones, prefixes, and applications, and can apply actions such as Allow, Deny, or Reject. Security policy sets are bound to sites so that the defined rules apply to the appropriate branch environment. Security policies therefore provide traffic-access control rather than simply determining the preferred WAN path. They are an important component of branch security because they can control application access between network segments and WAN-facing zones.<\/span><\/p>\n

                                        Question 20<\/b><\/h3>\n

                                        During flow processing, what happens after available paths are filtered according to path status and path-policy requirements?<\/b><\/p>\n

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

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

                                          After path status and path-policy processing identify the available candidate paths, Prisma SD-WAN proceeds to the Security Policy stage. The Zone-Based Firewall evaluates the candidate paths against applicable security rules. Paths that are not permitted by the security policy can be removed from consideration, leaving only paths that satisfy both forwarding and security requirements. This processing sequence demonstrates that path selection and security enforcement work together rather than operating as unrelated functions. The ION device therefore considers both network availability and security policy before completing forwarding decisions.<\/span><\/p>\n
