Question 381<\/b><\/h3>\n

Which Aruba CX technology provides high availability by allowing two switches to operate as a coordinated pair?<\/b><\/p>\n

    \n
  1. LACP<\/span><\/li>\n
  2. VSX<\/span><\/li>\n
  3. SNMP<\/span><\/li>\n
  4. NTP<\/span><\/li>\n<\/ol>\n

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

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

    Virtual Switching Extension (VSX) allows two Aruba CX switches to operate as a coordinated high-availability pair. The architecture provides redundant connectivity while allowing both switches to participate in forwarding. VSX uses a peer link and keepalive mechanism to maintain communication between the two switches and determine peer availability. LACP provides link aggregation, SNMP is used for network management, and NTP synchronizes system clocks. VSX is particularly useful in enterprise and data center environments where network devices need resilient connections to the switching infrastructure.<\/span><\/p>\n

    Question 382<\/b><\/h3>\n

    Which command displays the IPv4 routing table on an Aruba CX switch?<\/b><\/p>\n

      \n
    1. show vlan<\/span><\/li>\n
    2. show lldp neighbors<\/span><\/li>\n
    3. show ip route<\/span><\/li>\n
    4. show mac-address-table<\/span><\/li>\n<\/ol>\n

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

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

      The <\/span>show ip route<\/span> command displays the IPv4 routing table on an Aruba CX switch. The output can include connected, static, and dynamically learned routes, depending on the configuration. Administrators use the routing table to verify whether a destination network is known and determine the path that the switch will use for forwarding. <\/span>show vlan<\/span> provides VLAN information, <\/span>show lldp neighbors<\/span> displays directly connected neighbors, and <\/span>show mac-address-table<\/span> displays Layer 2 forwarding information. Checking the routing table is an important step when troubleshooting Layer 3 connectivity.<\/span><\/p>\n

      Question 383<\/b><\/h3>\n

      Which protocol is primarily used to exchange routing information between autonomous systems?<\/b><\/p>\n

        \n
      1. BGP<\/span><\/li>\n
      2. OSPF<\/span><\/li>\n
      3. DHCP<\/span><\/li>\n
      4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

        Border Gateway Protocol (BGP) is primarily used to exchange routing information between autonomous systems. It is a path-vector routing protocol that uses attributes and policies to determine how routes are selected and advertised. BGP is fundamental to Internet routing and is also used in environments requiring advanced routing-policy control. OSPF is generally used for internal routing, DHCP provides IP configuration, and LLDP provides neighbor discovery. Because BGP can influence large numbers of routes, administrators must carefully configure and validate its routing policies.<\/span><\/p>\n

        Question 384<\/b><\/h3>\n

        Which protocol is used to synchronize the clocks of network devices?<\/b><\/p>\n

          \n
        1. RADIUS<\/span><\/li>\n
        2. NTP<\/span><\/li>\n
        3. STP<\/span><\/li>\n
        4. ARP<\/span><\/li>\n<\/ol>\n

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

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

          Network Time Protocol (NTP) is used to synchronize the clocks of network devices with a configured time source. Accurate time is important for event logging, troubleshooting, authentication, security monitoring, and correlating events across multiple systems. Network administrators can configure devices to use reliable NTP servers or other trusted time sources. RADIUS provides authentication, STP prevents Layer 2 loops, and ARP resolves IPv4 addresses to MAC addresses. Consistent time across network infrastructure makes it much easier to understand when events occurred and correlate logs from different devices.<\/span><\/p>\n

          Question 385<\/b><\/h3>\n

          Which feature helps protect a switched network against unauthorized DHCP servers?<\/b><\/p>\n

            \n
          1. DHCP snooping<\/span><\/li>\n
          2. VRRP<\/span><\/li>\n
          3. OSPF<\/span><\/li>\n
          4. sFlow<\/span><\/li>\n<\/ol>\n

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

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

            DHCP snooping helps protect a Layer 2 network from rogue DHCP servers. The switch can identify trusted interfaces where legitimate DHCP server responses are expected and treat other interfaces as untrusted. DHCP responses arriving from an unauthorized interface can therefore be blocked. DHCP snooping can also create binding information containing IP addresses, MAC addresses, VLANs, and interfaces associated with legitimate DHCP assignments. VRRP provides gateway redundancy, OSPF provides routing, and sFlow provides traffic monitoring. DHCP snooping is an important security feature in enterprise switched networks.<\/span><\/p>\n

            Question 386<\/b><\/h3>\n

            Which protocol provides port-based network access control?<\/b><\/p>\n

              \n
            1. NTP<\/span><\/li>\n
            2. BGP<\/span><\/li>\n
            3. 802.1X<\/span><\/li>\n
            4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

              IEEE 802.1X provides port-based network access control. It can require a connected endpoint to authenticate before receiving normal network access. A typical implementation uses a supplicant on the endpoint, an authenticator such as an Ethernet switch, and an authentication server such as RADIUS. NTP synchronizes clocks, BGP exchanges routing information, and LLDP provides neighbor discovery. 802.1X is commonly deployed in enterprise networks to control access at the network edge and prevent unauthorized users or devices from gaining unrestricted connectivity through switch ports.<\/span><\/p>\n

              Question 387<\/b><\/h3>\n

              Which Aruba CX feature can provide continuous monitoring and analytics of switch conditions?<\/b><\/p>\n

                \n
              1. VRRP<\/span><\/li>\n
              2. NAE<\/span><\/li>\n
              3. LACP<\/span><\/li>\n
              4. NAT<\/span><\/li>\n<\/ol>\n

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

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

                The Network Analytics Engine (NAE) provides monitoring and analytics capabilities on supported Aruba CX switches. NAE agents can observe selected system and network conditions and provide information when configured events or thresholds occur. This allows administrators to identify operational problems proactively and investigate abnormal behavior. VRRP provides gateway redundancy, LACP manages link aggregation, and NAT performs address translation. NAE is useful when administrators need continuous visibility into switch operation without manually executing diagnostic commands at regular intervals.<\/span><\/p>\n

                Question 388<\/b><\/h3>\n

                Which protocol is commonly used to provide centralized authentication for network devices and users?<\/b><\/p>\n

                  \n
                1. RADIUS<\/span><\/li>\n
                2. OSPF<\/span><\/li>\n
                3. NTP<\/span><\/li>\n
                4. LACP<\/span><\/li>\n<\/ol>\n

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

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

                  RADIUS is commonly used to provide centralized authentication, authorization, and accounting services. Network devices can send authentication requests to a RADIUS server, allowing credentials and access policies to be managed centrally. RADIUS is frequently used with technologies such as 802.1X for network-access control. OSPF provides dynamic routing, NTP synchronizes clocks, and LACP manages aggregated links. Centralized authentication reduces the need to maintain separate credentials on every network device and can provide more consistent access-control policies across an organization.<\/span><\/p>\n

                  Question 389<\/b><\/h3>\n

                  Which type of switch port normally carries traffic for a single VLAN to an end device?<\/b><\/p>\n

                    \n
                  1. Trunk<\/span><\/li>\n
                  2. Routed<\/span><\/li>\n
                  3. Access<\/span><\/li>\n
                  4. Loopback<\/span><\/li>\n<\/ol>\n

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

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

                    An access port is normally associated with a single VLAN and is commonly used to connect end devices such as computers, printers, and other clients. Traffic toward the connected endpoint is generally transmitted without an 802.1Q VLAN tag in a typical access-port configuration. Trunk ports carry multiple VLANs, routed interfaces provide Layer 3 connectivity, and loopback interfaces are logical interfaces. Correctly configuring the access VLAN ensures that the endpoint is placed into the intended broadcast domain and can communicate with other devices in that network segment.<\/span><\/p>\n

                    Question 390<\/b><\/h3>\n

                    Which protocol can provide gateway redundancy using a shared virtual IP address?<\/b><\/p>\n

                      \n
                    1. SNMP<\/span><\/li>\n
                    2. VRRP<\/span><\/li>\n
                    3. DHCP<\/span><\/li>\n
                    4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

                      Virtual Router Redundancy Protocol (VRRP) provides default-gateway redundancy by allowing multiple routers to participate in a virtual router group. The routers share a virtual IP address that hosts can use as their default gateway. One router normally performs the active forwarding role, while another can assume that role if the active router becomes unavailable. SNMP provides network-management information, DHCP provides IP configuration, and LLDP provides neighbor discovery. VRRP improves gateway availability without requiring hosts to change their configured default-gateway address during a failover.<\/span><\/p>\n

                      Question 391<\/b><\/h3>\n

                      Which technology can combine several physical Ethernet links into a single logical interface?<\/b><\/p>\n

                        \n
                      1. LACP<\/span><\/li>\n
                      2. NTP<\/span><\/li>\n
                      3. RADIUS<\/span><\/li>\n
                      4. STP<\/span><\/li>\n<\/ol>\n

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

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

                        LACP, or Link Aggregation Control Protocol, allows compatible devices to negotiate and maintain an aggregated link. Multiple physical Ethernet interfaces can operate together as one logical connection, providing redundancy and potentially increasing aggregate bandwidth. LACP can detect compatible links and help maintain the aggregation when individual member links change state. NTP synchronizes time, RADIUS provides authentication, and STP prevents Layer 2 loops. Link aggregation is commonly used between switches and between switches and servers where multiple physical connections are needed for resilience or increased capacity.<\/span><\/p>\n

                        Question 392<\/b><\/h3>\n

                        Which IPv6 mechanism allows hosts to configure addresses using router advertisements?<\/b><\/p>\n

                          \n
                        1. ARP<\/span><\/li>\n
                        2. NAT<\/span><\/li>\n
                        3. SLAAC<\/span><\/li>\n
                        4. DHCP snooping<\/span><\/li>\n<\/ol>\n

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

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

                          Stateless Address Autoconfiguration (SLAAC) allows IPv6 hosts to configure addresses using information received through Router Advertisement messages. A router advertises an IPv6 network prefix, and the host uses that information to construct an appropriate address. SLAAC reduces the need for manual configuration and can simplify large IPv6 deployments. ARP is associated with IPv4 address resolution, NAT is primarily an IPv4 address-translation mechanism, and DHCP snooping is a Layer 2 security feature. Administrators should verify IPv6 Router Advertisements and prefix configuration when troubleshooting SLAAC.<\/span><\/p>\n

                          Question 393<\/b><\/h3>\n

                          Which protocol allows network devices to advertise their identity and capabilities to directly connected neighbors?<\/b><\/p>\n

                            \n
                          1. LLDP<\/span><\/li>\n
                          2. BGP<\/span><\/li>\n
                          3. DHCP<\/span><\/li>\n
                          4. RADIUS<\/span><\/li>\n<\/ol>\n

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

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

                            Link Layer Discovery Protocol (LLDP) allows network devices to advertise identifying and capability information to directly connected neighbors. Administrators can use LLDP information to identify connected devices, verify physical interfaces, and understand network topology. Depending on the implementation, information can include device identity, local and remote interface details, and system capabilities. BGP exchanges routing information, DHCP provides host configuration, and RADIUS provides authentication services. LLDP is especially useful during troubleshooting because it can quickly show which device is connected to a particular switch interface.<\/span><\/p>\n

                            Question 394<\/b><\/h3>\n

                            Which routing principle selects the most specific matching route?<\/b><\/p>\n

                              \n
                            1. Administrative distance<\/span><\/li>\n
                            2. Longest prefix match<\/span><\/li>\n
                            3. MAC learning<\/span><\/li>\n
                            4. VLAN tagging<\/span><\/li>\n<\/ol>\n

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

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

                              Longest prefix match determines which route should be selected when multiple routes match the same destination address. The route with the longest and therefore most specific prefix is preferred. For example, a <\/span>\/24<\/span> route is more specific than a <\/span>\/16<\/span> route when both contain the destination. Administrative distance is used when comparing routing sources, MAC learning is a Layer 2 switching function, and VLAN tagging identifies VLAN membership on tagged links. Understanding longest prefix matching is essential when troubleshooting routing tables and determining why a particular path is selected.<\/span><\/p>\n

                              Question 395<\/b><\/h3>\n

                              Which Aruba CX capability can provide sampled traffic information to an external monitoring system?<\/b><\/p>\n

                                \n
                              1. VRRP<\/span><\/li>\n
                              2. sFlow<\/span><\/li>\n
                              3. OSPF<\/span><\/li>\n
                              4. NTP<\/span><\/li>\n<\/ol>\n

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

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

                                sFlow provides sampled traffic information and interface statistics to an external collector. Instead of capturing every packet, the technology samples traffic and exports information for analysis. This can provide useful visibility into traffic sources, destinations, protocols, and utilization while reducing the overhead associated with full packet capture. VRRP provides gateway redundancy, OSPF provides dynamic routing, and NTP synchronizes device clocks. sFlow is useful for traffic analysis, capacity planning, troubleshooting high-utilization links, and identifying unusual traffic patterns across an enterprise network.<\/span><\/p>\n

                                Question 396<\/b><\/h3>\n

                                Which type of route is normally used when a network administrator manually specifies a destination and next hop?<\/b><\/p>\n

                                  \n
                                1. Connected route<\/span><\/li>\n
                                2. BGP route<\/span><\/li>\n
                                3. Static route<\/span><\/li>\n
                                4. OSPF route<\/span><\/li>\n<\/ol>\n

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

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

                                  A static route is manually configured by a network administrator and specifies a destination network together with a next hop or outgoing interface. Static routes can be useful for simple topologies, default routes, backup paths, and specific destinations where predictable forwarding is required. Connected routes are automatically associated with directly attached networks, while BGP and OSPF routes are learned through routing protocols. Because static routes do not automatically adapt to topology changes, administrators must review them carefully whenever network addressing or connectivity changes.<\/span><\/p>\n

                                  Question 397<\/b><\/h3>\n

                                  Which feature can validate ARP traffic using trusted IP-to-MAC binding information?<\/b><\/p>\n

                                    \n
                                  1. Dynamic ARP Protection<\/span><\/li>\n

                                  4. LACP<\/span><\/li>\n<\/ol>\n

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

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

                                    Dynamic ARP Protection can validate ARP traffic using trusted IP-to-MAC binding information. In a network using DHCP snooping, the switch can learn bindings from legitimate DHCP transactions. Dynamic ARP Protection can then use those bindings to identify ARP messages that do not match expected address mappings. This helps reduce the risk of ARP spoofing and poisoning within a Layer 2 network. NTP provides time synchronization, BGP exchanges routing information, and LACP manages link aggregation. Properly configured ARP protection can strengthen security at the access layer.<\/span><\/p>\n

                                    Question 398<\/b><\/h3>\n

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

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

                                      A trunk interface carries traffic belonging to multiple VLANs across a single physical Ethernet connection. VLAN tagging is used to identify the VLAN associated with frames traveling across the trunk. Trunks are commonly used between switches and can also connect switches to other devices that support VLAN tagging. An access interface normally carries one VLAN, a loopback is a logical interface, and a routed interface provides Layer 3 connectivity. Administrators should ensure that both ends of a trunk have compatible VLAN and tagging configurations.<\/span><\/p>\n

                                      Question 399<\/b><\/h3>\n

                                      Which command is useful for identifying the MAC addresses learned on switch interfaces?<\/b><\/p>\n

                                        \n
                                      1. show ip route<\/span><\/li>\n
                                      2. show vlan<\/span><\/li>\n
                                      3. show mac-address-table<\/span><\/li>\n
                                      4. show lldp neighbors<\/span><\/li>\n<\/ol>\n

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

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

                                        The <\/span>show mac-address-table<\/span> command provides information about MAC addresses learned by the switch. The MAC address table allows the switch to determine which interface should be used when forwarding Layer 2 frames toward a known destination. Administrators can use the command during troubleshooting to verify whether a connected device has been learned on the expected interface and VLAN. <\/span>show ip route<\/span> displays Layer 3 routes, <\/span>show vlan<\/span> provides VLAN information, and <\/span>show lldp neighbors<\/span> displays directly connected devices discovered through LLDP.<\/span><\/p>\n

                                        Question 400<\/b><\/h3>\n

                                        Which Aruba CX management platform provides centralized monitoring and configuration for supported network devices?<\/b><\/p>\n

                                          \n
                                        1. Aruba Central<\/span><\/li>\n
                                        2. OSPF<\/span><\/li>\n
                                        3. VRRP<\/span><\/li>\n
                                        4. ARP<\/span><\/li>\n<\/ol>\n

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

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

                                          Aruba Central provides centralized management, monitoring, configuration, and visibility for supported Aruba networking infrastructure. Administrators can use the platform to monitor device health, review alerts and events, manage configurations, and obtain information about connected network resources. Centralized management can simplify operations when an organization has many switches, access points, and other network devices. OSPF provides dynamic routing, VRRP provides gateway redundancy, and ARP resolves IPv4 addresses to MAC addresses. Aruba Central therefore supports centralized network operations rather than performing a specific packet-forwarding or routing function.<\/span><\/p>\n
