Question 161<\/b><\/h3>\n

Which Aruba CX feature allows two switches to operate as a redundant pair while maintaining independent control planes?<\/b><\/p>\n

    \n
  1. LACP<\/span><\/li>\n
  2. STP<\/span><\/li>\n
  3. VRRP<\/span><\/li>\n
  4. VSX<\/span><\/li>\n<\/ol>\n

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

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

    VSX allows two Aruba CX switches to operate as a redundant switching pair while maintaining separate control planes. The switches synchronize selected operational information and can provide resilient forwarding for connected devices. VSX is commonly used in campus aggregation and data-center designs where high availability is required. Unlike traditional chassis-based redundancy, each VSX member maintains its own control functions. LACP can be used with VSX to create multi-chassis link aggregation, while VRRP provides gateway redundancy and STP provides loop prevention. Proper VSX configuration helps eliminate single-switch dependencies in resilient network architectures.<\/span><\/p>\n

    Question 162<\/b><\/h3>\n

    Which routing protocol uses a link-state database to calculate paths within an autonomous system?<\/b><\/p>\n

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

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

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

      OSPF is a link-state interior gateway routing protocol. It builds a link-state database representing the topology of an OSPF area and uses the Shortest Path First algorithm to calculate routes. OSPF can support hierarchical network designs through multiple areas and can dynamically adapt when topology changes occur. BGP is primarily used for inter-domain routing, RADIUS provides centralized authentication, and LLDP discovers directly connected neighbors. OSPF is commonly deployed in enterprise networks where dynamic routing, fast convergence, and scalable topology management are required.<\/span><\/p>\n

      Question 163<\/b><\/h3>\n

      Which feature can prevent unauthorized DHCP server messages from being accepted on untrusted switch interfaces?<\/b><\/p>\n

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

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

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

        DHCP snooping helps protect a network from rogue DHCP servers by distinguishing trusted and untrusted switch interfaces. DHCP server responses are expected to arrive through trusted interfaces. If a DHCP server message is received through an untrusted interface, the switch can block it according to the configured policy. DHCP snooping can also create a binding database containing information about clients, addresses, MAC addresses, and ports. This database can support additional security mechanisms such as Dynamic ARP Protection. VRRP provides gateway redundancy, NTP synchronizes time, and BGP exchanges routing information.<\/span><\/p>\n

        Question 164<\/b><\/h3>\n

        Which protocol provides first-hop gateway redundancy using a virtual IP address?<\/b><\/p>\n

          \n
        1. OSPF<\/span><\/li>\n
        2. LACP<\/span><\/li>\n
        3. VRRP<\/span><\/li>\n
        4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

          VRRP provides first-hop redundancy by allowing multiple Layer 3 devices to participate in a virtual router configuration. Hosts can use the virtual IP address as their default gateway instead of depending on a single physical router address. One participating device normally performs the active forwarding role, while another can take over if the active device fails. OSPF provides dynamic routing, LACP provides link aggregation, and LLDP provides neighbor discovery. VRRP is useful in enterprise networks because a gateway failure does not necessarily require changes to endpoint configurations.<\/span><\/p>\n

          Question 165<\/b><\/h3>\n

          Which protocol dynamically negotiates link aggregation between compatible network devices?<\/b><\/p>\n

            \n
          1. LACP<\/span><\/li>\n
          2. STP<\/span><\/li>\n
          3. DHCP<\/span><\/li>\n
          4. ARP<\/span><\/li>\n<\/ol>\n

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

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

            LACP dynamically negotiates and manages link aggregation between compatible network devices. Multiple physical interfaces can be combined into a logical Link Aggregation Group, providing redundancy and potentially increased aggregate bandwidth. LACP also helps ensure that participating interfaces are correctly associated with the same aggregation group. STP prevents Layer 2 loops, DHCP provides IP configuration, and ARP resolves IPv4 addresses to MAC addresses. LACP is commonly used for switch-to-switch uplinks and server connections where multiple physical links are needed for improved availability and capacity.<\/span><\/p>\n

            Question 166<\/b><\/h3>\n

            Which protocol provides encrypted command-line management access to an Aruba CX switch?<\/b><\/p>\n

              \n
            1. Telnet<\/span><\/li>\n
            2. SSH<\/span><\/li>\n
            3. TFTP<\/span><\/li>\n
            4. FTP<\/span><\/li>\n<\/ol>\n

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

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

              SSH provides secure, encrypted command-line access to network devices. It protects management sessions by encrypting information exchanged between the administrator and the switch, including credentials and commands. This makes SSH preferable to Telnet, which does not provide comparable encryption for interactive management traffic. TFTP and FTP are file-transfer protocols rather than interactive secure management protocols. Network administrators should also restrict SSH access to authorized management networks and use appropriate authentication controls. Secure remote management is an important part of protecting network infrastructure from unauthorized administrative access.<\/span><\/p>\n

              Question 167<\/b><\/h3>\n

              Which protocol allows a switch to discover information about directly connected neighboring devices?<\/b><\/p>\n

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

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

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

                LLDP allows network devices to advertise information about themselves to directly connected neighbors. Administrators can use LLDP information to identify neighboring device names, interfaces, capabilities, and other details. This is particularly useful when validating physical topology or troubleshooting an unexpected connection. NTP synchronizes clocks, RADIUS provides authentication and accounting, and BGP exchanges routing information. Because LLDP operates at Layer 2, it can provide useful neighbor information without depending on normal IP routing between the devices. It is commonly used during network deployment and troubleshooting.<\/span><\/p>\n

                Question 168<\/b><\/h3>\n

                Which authentication service is commonly integrated with 802.1X for centralized user or device authentication?<\/b><\/p>\n

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

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

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

                  RADIUS is commonly used with 802.1X to provide centralized authentication and authorization. In a typical deployment, the endpoint acts as the supplicant, the switch acts as the authenticator, and the RADIUS server validates the authentication request. The resulting authorization can determine what network access the endpoint receives. OSPF handles dynamic routing, STP prevents Layer 2 loops, and LACP provides link aggregation. Using RADIUS with 802.1X allows organizations to centrally manage network access policies rather than maintaining separate authentication information on every individual switch.<\/span><\/p>\n

                  Question 169<\/b><\/h3>\n

                  Which protocol resolves an IPv4 address to a MAC address on an Ethernet network?<\/b><\/p>\n

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

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

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

                    Address Resolution Protocol, or ARP, maps an IPv4 address to the corresponding MAC address on a local Ethernet network. When a device needs to send traffic to a local IPv4 destination and does not know its MAC address, it can send an ARP request. The device associated with the requested IPv4 address responds with its MAC address, allowing Ethernet communication to proceed. NTP provides time synchronization, BGP handles routing information exchange, and RADIUS provides authentication services. ARP is therefore an essential component of IPv4 communication on Ethernet networks.<\/span><\/p>\n

                    Question 170<\/b><\/h3>\n

                    Which protocol prevents Layer 2 loops by placing redundant switch paths into a non-forwarding state?<\/b><\/p>\n

                      \n
                    1. STP<\/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

                      Spanning Tree Protocol prevents Layer 2 switching loops by logically blocking selected redundant paths while maintaining them as potential alternatives. Without loop prevention, redundant Ethernet connections can create broadcast storms and unstable MAC-address learning. STP evaluates the topology and determines which interfaces should forward traffic and which should remain in a non-forwarding state. If the active path fails, an alternate path can become available according to the spanning-tree operation. BGP handles routing between autonomous systems, DHCP provides IP configuration, and RADIUS provides centralized authentication.<\/span><\/p>\n

                      Question 171<\/b><\/h3>\n

                      Which Aruba CX capability can monitor operational conditions and provide automated analytics?<\/b><\/p>\n

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

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

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

                        The Network Analytics Engine, or NAE, provides monitoring and analytics capabilities on Aruba CX switches. It can observe selected operational information and identify conditions that may require administrator attention. NAE can help with proactive monitoring by analyzing device behavior instead of requiring administrators to manually inspect every statistic or log entry. VRRP provides gateway redundancy, LACP manages aggregated links, and ARP resolves IPv4 addresses. NAE can therefore support troubleshooting and operational visibility by helping administrators identify unusual conditions and investigate network events more efficiently.<\/span><\/p>\n

                        Question 172<\/b><\/h3>\n

                        Which protocol is used to synchronize the clocks of network devices with a reliable time source?<\/b><\/p>\n

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

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

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

                          Network Time Protocol synchronizes device clocks with configured time sources. Accurate time is important for logging, troubleshooting, monitoring, authentication, and security investigations. When switches and other network devices use consistent timestamps, administrators can correlate events across multiple systems more accurately. OSPF is used for routing, VRRP provides gateway redundancy, and LLDP discovers neighboring devices. NTP configuration should include appropriate and reliable time sources, and administrators should verify synchronization status rather than assuming that simply configuring an NTP server guarantees accurate time.<\/span><\/p>\n

                          Question 173<\/b><\/h3>\n

                          Which security mechanism can use DHCP snooping bindings to validate ARP messages?<\/b><\/p>\n

                            \n
                          1. Dynamic ARP Protection<\/span><\/li>\n
                          2. LACP<\/span><\/li>\n
                          3. NTP<\/span><\/li>\n
                          4. BGP<\/span><\/li>\n<\/ol>\n

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

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

                            Dynamic ARP Protection can validate ARP traffic against trusted IP-to-MAC binding information. DHCP snooping can create a binding database that identifies relationships between client IP addresses, MAC addresses, and switch ports. Dynamic ARP Protection can use this information to identify suspicious ARP messages that do not match expected bindings. LACP provides link aggregation, NTP synchronizes clocks, and BGP exchanges routing information. Combining DHCP snooping with Dynamic ARP Protection provides an additional layer of protection against ARP spoofing and other malicious manipulation of Layer 2 address-resolution information.<\/span><\/p>\n

                            Question 174<\/b><\/h3>\n

                            Which protocol is designed primarily for exchanging routing information between autonomous systems?<\/b><\/p>\n

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

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

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

                              Border Gateway Protocol is designed to exchange routing information between autonomous systems. BGP is the primary routing protocol used for Internet-scale inter-domain routing and can also support organizations with multiple external routing relationships. It uses path attributes and routing policies to control route advertisements and route selection. OSPF is commonly used for internal routing, STP prevents Layer 2 loops, and LLDP discovers directly connected devices. Because BGP can influence large-scale traffic flows, administrators need to carefully configure policies and verify route advertisements.<\/span><\/p>\n

                              Question 175<\/b><\/h3>\n

                              Which feature provides sampled traffic information for monitoring network flows and interface utilization?<\/b><\/p>\n

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

                              3. sFlow<\/span><\/li>\n
                              4. DHCP relay<\/span><\/li>\n<\/ol>\n

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

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

                                sFlow provides sampled traffic information that can be collected by a monitoring system for analysis. It can help administrators understand traffic patterns, identify high-utilization interfaces, and determine major traffic sources and destinations. Sampling provides network visibility without requiring every packet to be processed or stored. VRRP provides gateway redundancy, 802.1X controls network access, and DHCP relay forwards DHCP messages across Layer 3 boundaries. sFlow is useful for troubleshooting, performance monitoring, capacity planning, and identifying unusual traffic patterns across an enterprise network.<\/span><\/p>\n

                                Question 176<\/b><\/h3>\n

                                Which interface type is normally assigned to a single VLAN for an end-user device?<\/b><\/p>\n

                                  \n

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

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

                                  An access interface is normally associated with a single VLAN and is commonly used to connect end-user devices. Traffic arriving from the endpoint is typically treated as belonging to the configured access VLAN. Trunk interfaces are designed to carry traffic for multiple VLANs, routed interfaces provide Layer 3 connectivity, and loopback interfaces are logical interfaces used for specific networking purposes. Correctly assigning an access VLAN is important because a mismatch can prevent a connected device from reaching the intended gateway and network services.<\/span><\/p>\n

                                  Question 177<\/b><\/h3>\n

                                  Which IPv6 feature allows hosts to configure addresses using information received from IPv6 routers?<\/b><\/p>\n

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

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

                                    Stateless Address Autoconfiguration, or SLAAC, allows IPv6 hosts to configure addresses using network prefix information received through IPv6 Router Advertisements. This reduces the need for manually configuring every host with an address. The host combines the advertised prefix with an interface identifier according to the applicable IPv6 configuration behavior. ARP is associated with IPv4, DHCPv4 provides IPv4 configuration, and FTP is a file-transfer protocol. SLAAC is widely used in IPv6 networks and can operate alongside other IPv6 configuration mechanisms when additional information is required.<\/span><\/p>\n

                                      Longest prefix match determines which matching route is most specific to the destination. A route with a longer network prefix represents a smaller address range and therefore provides more specific forwarding information than a broader route. For example, a specific subnet route can be selected instead of a larger summarized network route when both match the destination address. The default route is a fallback when no more specific route exists. Understanding longest prefix matching is essential for troubleshooting situations where several entries in a routing table appear capable of reaching the same destination.<\/span><\/p>\n

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

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

                                        802.1X provides port-based network access control and can require an endpoint to authenticate before receiving normal network access. It commonly works with a RADIUS server, which performs authentication and authorization. This architecture allows organizations to control which users or devices can access network resources through specific switch ports. NTP synchronizes device clocks, LACP provides link aggregation, and OSPF provides dynamic routing. 802.1X is particularly useful at the network edge where administrators want to prevent unauthorized devices from gaining unrestricted connectivity simply by connecting to an Ethernet port.<\/span><\/p>\n

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

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

                                          Multi-chassis Link Aggregation allows a downstream device to form a logical aggregated connection using physical links connected to both switches in a VSX pair. This provides redundancy because the downstream device does not rely on a single physical switch for connectivity. LACP can dynamically manage the aggregated links when configured appropriately. A static route controls Layer 3 forwarding, DHCP relay forwards DHCP messages across routed boundaries, and NTP synchronizes device clocks. Multi-chassis LAG is an important high-availability design technique for Aruba CX environments requiring resilient Layer 2 connectivity.<\/span><\/p>\n
