Question 61<\/b><\/h3>\n

Which ACI component is responsible for applying forwarding and policy decisions to connected endpoints?<\/b><\/p>\n

    \n
  1. Spine switch<\/span><\/li>\n
  2. APIC<\/span><\/li>\n
  3. Leaf switch<\/span><\/li>\n
  4. APIC cluster<\/span><\/li>\n<\/ol>\n

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

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

    Leaf switches are the primary point of connectivity for endpoints in a Cisco ACI fabric. They connect servers, virtual environments, external devices, and other network infrastructure while implementing the policies programmed through APIC. Leaf switches perform forwarding functions and maintain endpoint information needed to deliver traffic through the fabric. Spine switches provide transit between leaf switches, while APIC provides centralized management and policy orchestration. The APIC cluster supports management resiliency but does not normally perform endpoint data-plane forwarding. When troubleshooting endpoint connectivity, administrators should inspect the relevant leaf switch, interface configuration, endpoint learning information, and applied policy.<\/span><\/p>\n

    Question 62<\/b><\/h3>\n

    Which ACI object provides administrative isolation between different organizational environments?<\/b><\/p>\n

      \n
    1. Tenant<\/span><\/li>\n
    2. Contract<\/span><\/li>\n
    3. Filter<\/span><\/li>\n
    4. VLAN pool<\/span><\/li>\n<\/ol>\n

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

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

      A tenant provides a logical administrative and policy boundary within Cisco ACI. Organizations can use tenants to separate applications, networking resources, and policies according to operational requirements. Tenants can contain objects such as VRFs, bridge domains, application profiles, EPGs, contracts, and external connectivity configurations. Contracts define communication policies, filters identify permitted traffic, and VLAN pools provide encapsulation resources. Tenant separation helps administrators organize and control policy ownership while supporting multiple environments on the same physical fabric. When designing an ACI deployment, administrators should determine appropriate tenant boundaries based on application ownership, operational responsibilities, and required levels of logical separation.<\/span><\/p>\n

      Question 63<\/b><\/h3>\n

      Which ACI object is directly associated with an application profile to group application endpoints?<\/b><\/p>\n

        \n
      1. VLAN pool<\/span><\/li>\n
      2. EPG<\/span><\/li>\n
      3. L3Out<\/span><\/li>\n
      4. Interface policy<\/span><\/li>\n<\/ol>\n

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

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

        Endpoint Groups are contained within application profiles and represent collections of endpoints that require similar policy treatment. An application profile can contain multiple EPGs representing different application tiers, such as web, application, and database servers. EPGs can then participate in contract relationships that control communication. VLAN pools provide encapsulation resources, L3Out objects provide external Layer 3 connectivity, and interface policies control physical interface behavior. Understanding the relationship between application profiles and EPGs is important when designing ACI policy. Administrators should ensure that endpoints are assigned to the correct EPG so the intended contracts and forwarding policies are applied.<\/span><\/p>\n

        Question 64<\/b><\/h3>\n

        What is the primary purpose of a bridge-domain subnet in Cisco ACI?<\/b><\/p>\n

          \n
        1. To identify an APIC controller<\/span><\/li>\n
        2. To allocate VLAN IDs<\/span><\/li>\n
        3. To provide Layer 3 gateway addressing<\/span><\/li>\n
        4. To define a contract filter<\/span><\/li>\n<\/ol>\n

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

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

          A subnet configured under an ACI bridge domain can provide the Layer 3 gateway address for endpoints associated with that bridge domain. The gateway allows hosts to communicate with destinations outside their local subnet and can participate in ACI routing according to the associated VRF and policy configuration. VLAN pools allocate encapsulation resources, contract filters define traffic rules, and APIC controllers provide management and policy services. Administrators should verify the subnet configuration, gateway address, and VRF association when troubleshooting Layer 3 communication. Incorrect gateway configuration can prevent endpoints from reaching remote networks even when physical connectivity is functioning correctly.<\/span><\/p>\n

          Question 65<\/b><\/h3>\n

          Which ACI policy is used to control how long learned endpoint information is retained?<\/b><\/p>\n

            \n
          1. Endpoint retention policy<\/span><\/li>\n
          2. Route control policy<\/span><\/li>\n
          3. Contract<\/span><\/li>\n
          4. VLAN pool<\/span><\/li>\n<\/ol>\n

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

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

            An endpoint retention policy controls how ACI handles learned endpoint information over time. It can influence the behavior used when endpoint information becomes stale or when an endpoint is no longer actively detected. This is useful in environments where endpoint movement, aging, or temporary connectivity changes need to be handled predictably. Route control policies manage routing information, contracts regulate communication between EPGs, and VLAN pools provide VLAN resources. When troubleshooting stale endpoint entries or unexpected endpoint behavior, administrators should review endpoint learning and retention settings. Correct retention behavior helps maintain an accurate representation of active endpoints within the ACI fabric.<\/span><\/p>\n

            Question 66<\/b><\/h3>\n

            Which protocol is commonly used to exchange routing information between an ACI L3Out and an external router?<\/b><\/p>\n

              \n
            1. CDP<\/span><\/li>\n
            2. OSPF<\/span><\/li>\n
            3. LLDP<\/span><\/li>\n
            4. VTP<\/span><\/li>\n<\/ol>\n

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

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

              OSPF is a dynamic routing protocol that can be configured between an ACI L3Out and an external router. It allows both sides to exchange routing information and dynamically learn reachable prefixes. Administrators must configure compatible OSPF parameters, including area information and interface settings, for adjacency to form correctly. CDP and LLDP are discovery protocols rather than routing protocols, while VTP is associated with VLAN management. After configuring OSPF, administrators should verify neighbor relationships, routing tables, and route advertisement behavior. This helps confirm that external connectivity is functioning and that the expected routes are being exchanged between the ACI fabric and external network.<\/span><\/p>\n

              Question 67<\/b><\/h3>\n

              Which ACI feature is commonly used to provide redundant connectivity from a leaf pair to a dual-attached external device?<\/b><\/p>\n

                \n
              1. vPC<\/span><\/li>\n
              2. SNMP<\/span><\/li>\n
              3. Syslog<\/span><\/li>\n
              4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

                Virtual Port Channel, or vPC, allows two ACI leaf switches to present coordinated connectivity to a dual-attached device. This design can provide redundancy and improve availability by allowing the connected device to use links toward both leaf switches. vPC-related configuration must be consistent with the intended interface policy and access design. SNMP and syslog are management and monitoring functions, while LLDP provides neighbor discovery. Administrators should verify the leaf pair configuration, interface policy group, physical connections, and operational status when troubleshooting dual-attached endpoints. Correct vPC deployment helps prevent unnecessary single points of failure in the access layer.<\/span><\/p>\n

                Question 68<\/b><\/h3>\n

                Which ACI policy object is used to define settings such as speed, duplex, or link-level behavior for interfaces?<\/b><\/p>\n

                  \n
                1. Contract<\/span><\/li>\n
                2. VRF<\/span><\/li>\n
                3. Interface policy<\/span><\/li>\n
                4. Application profile<\/span><\/li>\n<\/ol>\n

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

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

                  Interface policies define operational characteristics that can be applied to ACI interfaces. Depending on the policy type, they can control settings such as speed, link behavior, CDP, LLDP, or other interface-related functions. These policies are combined through interface policy groups and applied to selected interfaces using interface profiles and selectors. Contracts and VRFs serve higher-level policy and routing functions, while application profiles organize EPGs. Proper interface-policy configuration is important because mismatched physical settings can cause connectivity or operational problems. During troubleshooting, administrators should verify both the individual interface policies and the policy group applied to the affected port.<\/span><\/p>\n

                  Question 69<\/b><\/h3>\n

                  What is the purpose of an interface selector in the ACI access policy model?<\/b><\/p>\n

                    \n
                  1. To define which interfaces receive an access policy<\/span><\/li>\n
                  2. To create an external routing protocol<\/span><\/li>\n
                  3. To assign APIC administrator roles<\/span><\/li>\n
                  4. To define a bridge-domain subnet<\/span><\/li>\n<\/ol>\n

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

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

                    An interface selector identifies the leaf interfaces to which a particular access policy should be applied. It works with interface profiles and policy groups to create the relationship between physical interfaces and the desired configuration. This model allows administrators to apply policies consistently across specific ports instead of configuring every interface independently. Routing protocols, administrator roles, and bridge-domain subnets are configured through different ACI objects. When an endpoint cannot connect as expected, administrators should verify that the correct interface selector identifies the intended port and that the associated policy group contains the required settings. Accurate selector configuration is essential for proper endpoint attachment.<\/span><\/p>\n

                    Question 70<\/b><\/h3>\n

                    Which ACI component maintains the centralized policy and configuration information for the fabric?<\/b><\/p>\n

                      \n
                    1. Spine switch<\/span><\/li>\n
                    2. APIC<\/span><\/li>\n
                    3. External router<\/span><\/li>\n
                    4. Endpoint<\/span><\/li>\n<\/ol>\n

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

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

                      APIC maintains and manages the centralized policy and configuration information used by the Cisco ACI fabric. Administrators create tenants, VRFs, bridge domains, EPGs, contracts, domains, access policies, and external connectivity configurations through APIC. The fabric switches receive and implement the resulting configuration, while external routers provide connectivity outside the ACI environment. Centralized policy management is one of the main characteristics of ACI’s application-centric architecture. Administrators can also use APIC to monitor faults, events, health, and operational state. Maintaining a healthy APIC cluster is therefore important for reliable configuration and management of the overall ACI environment.<\/span><\/p>\n

                      Question 71<\/b><\/h3>\n

                      Which routing protocol uses autonomous system numbers and is commonly deployed for external connectivity in large networks?<\/b><\/p>\n

                        \n
                      1. OSPF<\/span><\/li>\n
                      2. EIGRP<\/span><\/li>\n
                      3. BGP<\/span><\/li>\n
                      4. CDP<\/span><\/li>\n<\/ol>\n

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

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

                        Border Gateway Protocol, or BGP, uses autonomous system numbers and is widely used for exchanging routing information between autonomous systems. Cisco ACI supports BGP through appropriate L3Out configurations for external connectivity. BGP is particularly useful where organizations require policy-based control over route advertisements and connectivity with external routing domains. OSPF is an interior gateway protocol, EIGRP is another routing protocol designed for internal networks, and CDP is a neighbor-discovery protocol. When deploying BGP with an ACI L3Out, administrators should verify the local and remote autonomous system configuration, peer reachability, session state, and route advertisement policies.<\/span><\/p>\n

                        Question 72<\/b><\/h3>\n

                        Which ACI object determines the routing domain to which a bridge domain belongs?<\/b><\/p>\n

                          \n
                        1. EPG<\/span><\/li>\n
                        2. Contract<\/span><\/li>\n
                        3. VRF<\/span><\/li>\n
                        4. VLAN pool<\/span><\/li>\n<\/ol>\n

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

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

                          A VRF defines the Layer 3 routing context for bridge domains in Cisco ACI. A bridge domain is associated with a VRF, and this relationship determines the routing domain in which its subnet and traffic operate. Separate VRFs can provide logical routing isolation between environments that may use overlapping address spaces. EPGs define endpoint groups, contracts regulate communication policies, and VLAN pools manage encapsulation resources. When troubleshooting routing problems, administrators should confirm that the bridge domain is associated with the intended VRF. An incorrect association can isolate endpoints from expected routes or place them into an unintended routing context.<\/span><\/p>\n

                          Question 73<\/b><\/h3>\n

                          Which ACI object is used to define the set of VLAN encapsulations that can be allocated to a domain?<\/b><\/p>\n

                            \n
                          1. VLAN pool<\/span><\/li>\n
                          2. VRF<\/span><\/li>\n
                          3. Contract<\/span><\/li>\n
                          4. Tenant<\/span><\/li>\n<\/ol>\n

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

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

                            A VLAN pool defines a range or set of VLAN encapsulations that can be allocated for ACI domains. It is commonly associated with physical, VMM, or external connectivity domains depending on the deployment design. The VLAN pool provides the encapsulation resources required when an EPG is deployed on a particular domain. VRFs provide routing contexts, contracts control communication, and tenants provide administrative boundaries. Administrators should ensure that VLAN ranges are correctly defined and appropriate for the connected infrastructure. Incorrect VLAN pool configuration can prevent an EPG from being deployed correctly or can cause encapsulation conflicts with existing network resources.<\/span><\/p>\n

                            Question 74<\/b><\/h3>\n

                            Which ACI feature allows policies to be applied based on application or endpoint groups rather than individual device configurations?<\/b><\/p>\n

                              \n
                            1. Traditional VLAN configuration<\/span><\/li>\n
                            2. Application-centric policy model<\/span><\/li>\n
                            3. Static MAC learning<\/span><\/li>\n
                            4. Manual route configuration<\/span><\/li>\n<\/ol>\n

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

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

                              The application-centric policy model is a fundamental concept in Cisco ACI. Instead of configuring individual network devices independently, administrators define logical objects such as tenants, application profiles, EPGs, contracts, and bridge domains. These policies describe application requirements and relationships, while the fabric translates them into the necessary device-level configuration. Traditional VLAN configuration and static routes can still be part of network designs, but they do not provide the same application-centric abstraction. This approach improves consistency and simplifies policy management. Administrators can focus on how applications should communicate rather than manually configuring every switch interface and forwarding rule.<\/span><\/p>\n

                              Question 75<\/b><\/h3>\n

                              Which ACI feature can provide rapid detection of certain forwarding-path failures between network devices?<\/b><\/p>\n

                                \n
                              1. BFD<\/span><\/li>\n
                              2. CDP<\/span><\/li>\n
                              3. DHCP<\/span><\/li>\n
                              4. VTP<\/span><\/li>\n<\/ol>\n

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

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

                                Bidirectional Forwarding Detection, or BFD, is designed to provide rapid detection of forwarding-path failures. It can be used with supported routing protocols and network configurations to reduce the time required to identify a failed forwarding path. CDP discovers Cisco neighbors, DHCP provides address assignment, and VTP is associated with VLAN information management. Fast failure detection can be important for external routing connections where slow failure recognition could interrupt application traffic for longer periods. When implementing BFD, administrators should verify support, interface configuration, routing-protocol integration, and operational state to ensure that the expected failure-detection behavior is achieved.<\/span><\/p>\n

                                Question 76<\/b><\/h3>\n

                                Which ACI object is used to define a relationship where one EPG consumes services provided by another EPG?<\/b><\/p>\n

                                  \n
                                1. VLAN pool<\/span><\/li>\n

                                3. Interface selector<\/span><\/li>\n
                                4. Bridge domain<\/span><\/li>\n<\/ol>\n

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

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

                                  A contract defines the communication relationship between consumer and provider EPGs. The consumer EPG requests access to services, while the provider EPG offers those services. Filters associated with the contract define the traffic that can be permitted. This model enables administrators to express application dependencies explicitly, such as allowing a web EPG to communicate with an application EPG on specific ports. VLAN pools, interface selectors, and bridge domains serve different purposes within the ACI policy model. When troubleshooting application communication, administrators should confirm the contract relationship, subject configuration, filters, and EPG roles.<\/span><\/p>\n

                                  Question 77<\/b><\/h3>\n

                                  Which management protocol can be used to collect monitoring information from ACI devices and infrastructure?<\/b><\/p>\n

                                    \n
                                  1. FTP<\/span><\/li>\n

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

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

                                    Simple Network Management Protocol, or SNMP, can be used to collect monitoring and management information from supported network infrastructure. It can provide information about device health, interfaces, counters, and other operational data to a network management system. FTP and TFTP are primarily file-transfer protocols, while Telnet provides remote terminal access and is not a dedicated monitoring protocol. In production environments, administrators should configure appropriate SNMP versions, authentication, access restrictions, and management destinations according to organizational requirements. Monitoring systems can then use SNMP data to identify interface problems, resource conditions, and other operational events across the network infrastructure.<\/span><\/p>\n

                                    Question 78<\/b><\/h3>\n

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

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

                                      Syslog provides a mechanism for collecting and forwarding event messages generated by network infrastructure. Centralized logging can help administrators investigate configuration changes, interface events, authentication activity, and other operational conditions. EPGs define endpoint groups, VLAN pools manage encapsulation resources, and L3Out provides external Layer 3 connectivity. Effective logging requires appropriate destinations, severity levels, and retention practices. Administrators should correlate syslog information with APIC faults, events, and other operational data when troubleshooting. Centralized logs can be especially useful when investigating intermittent problems because they provide historical information that may no longer be visible from the current device state.<\/span><\/p>\n

                                      Question 79<\/b><\/h3>\n

                                      Which ACI concept is used to provide logical separation of routing tables between different environments?<\/b><\/p>\n

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

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

                                        A VRF provides logical separation between routing tables and Layer 3 forwarding contexts. Different VRFs can maintain independent routing information, allowing multiple environments to use separate address spaces and routing policies on the same physical infrastructure. EPGs group endpoints, contracts control communication between EPGs, and filters specify traffic characteristics. VRF isolation is important in multi-tenant or multi-application environments where traffic should remain logically separated. Administrators should verify VRF associations when diagnosing routing problems because an endpoint can have correct physical connectivity but still fail to reach a destination if it belongs to an unexpected or isolated routing context.<\/span><\/p>\n

                                        Question 80<\/b><\/h3>\n

                                        Which ACI component provides the physical access point for servers and other connected endpoints?<\/b><\/p>\n

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

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

                                          Leaf switches provide the physical access layer for servers, appliances, virtual infrastructure connections, and other endpoints in an ACI fabric. They connect directly to endpoint-facing interfaces and apply the policies programmed through APIC. Spine switches provide transit between leaf switches rather than normally connecting directly to endpoints. APIC provides centralized management and policy orchestration, while external routers provide connectivity beyond the ACI fabric. When troubleshooting endpoint connectivity, administrators should begin by checking the relevant leaf interface, access policy, endpoint learning state, VLAN or encapsulation assignment, and EPG association. These elements determine how the connected endpoint participates in the ACI fabric.<\/span><\/p>\n
