Question 141<\/b><\/h3>\n

An administrator wants to provide network access to a device only after its identity has been successfully authenticated. Which security approach is appropriate?<\/b><\/p>\n

    \n
  1. Broadcast forwarding<\/span><\/li>\n
  2. Static routing<\/span><\/li>\n
  3. Open access<\/span><\/li>\n
  4. Authentication-based access control<\/span><\/li>\n<\/ol>\n

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

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

    Authentication-based access control requires a user or device to successfully authenticate before receiving the intended network access. This approach allows the network to make access decisions based on verified identity or associated authorization information. It can be integrated with centralized authentication services and role-based policies. Open access does not provide equivalent identity verification, while static routing concerns packet forwarding and broadcast forwarding concerns Layer 2 traffic behavior. Therefore, authentication-based access control is the appropriate approach when network access should depend on successful identity verification.<\/span><\/p>\n

    Question 142<\/b><\/h3>\n

    An Aruba administrator needs to divide a physical switch into multiple logical broadcast domains. Which technology should be configured?<\/b><\/p>\n

      \n
    1. VLANs<\/span><\/li>\n
    2. OSPF<\/span><\/li>\n
    3. SNMP<\/span><\/li>\n
    4. NTP<\/span><\/li>\n<\/ol>\n

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

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

      VLANs divide a physical switching infrastructure into separate logical Layer 2 broadcast domains. Devices in different VLANs are logically separated even when they use the same physical switch. Communication between VLANs requires Layer 3 routing or another appropriate gateway mechanism. OSPF is a dynamic routing protocol, SNMP is used for network monitoring, and NTP synchronizes device clocks. VLAN segmentation is commonly used to separate departments, users, voice devices, management traffic, and guest networks. Therefore, VLANs are the correct technology for creating multiple logical broadcast domains.<\/span><\/p>\n

      Question 143<\/b><\/h3>\n

      A network administrator needs to determine whether a switch interface is operating at the expected Ethernet speed and duplex settings. Which interface information should be checked?<\/b><\/p>\n

        \n
      1. DNS status<\/span><\/li>\n
      2. RADIUS logs<\/span><\/li>\n
      3. Link speed and duplex<\/span><\/li>\n
      4. NTP server address<\/span><\/li>\n<\/ol>\n

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

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

        Link speed and duplex information shows how an Ethernet interface is currently operating. Checking these values can help identify mismatches or unexpected negotiation results that may affect network performance. A duplex mismatch can cause errors, retransmissions, and degraded throughput in environments where it occurs. DNS status concerns name resolution, RADIUS logs concern authentication activity, and NTP server addresses identify time synchronization sources. Therefore, interface link speed and duplex settings should be reviewed when verifying that an Ethernet connection is operating according to expectations.<\/span><\/p>\n

        Question 144<\/b><\/h3>\n

        Which VLAN configuration allows a switch port to carry traffic belonging to multiple tagged VLANs?<\/b><\/p>\n

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

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

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

          Trunk mode allows a switch interface to carry traffic for multiple VLANs, normally using VLAN tags to identify the VLAN associated with each frame. Trunks are commonly used between switches, between switches and routers, or between switches and other network devices that need access to multiple VLANs. An access port normally carries traffic for a single VLAN, while a routed interface performs Layer 3 forwarding rather than traditional VLAN trunking. A loopback is a logical interface. Therefore, trunk mode is the appropriate configuration for carrying multiple tagged VLANs over one physical link.<\/span><\/p>\n

          Question 145<\/b><\/h3>\n

          An administrator wants to identify the MAC address associated with a learned device on a particular switch interface. Which table should be examined?<\/b><\/p>\n

            \n
          1. Routing table<\/span><\/li>\n
          2. MAC address table<\/span><\/li>\n
          3. DNS table<\/span><\/li>\n
          4. NTP table<\/span><\/li>\n<\/ol>\n

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

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

            A switch MAC address table records dynamically or statically learned MAC addresses and associates them with switch interfaces and VLAN information. Administrators can use this table to determine where a particular Layer 2 device has been learned and troubleshoot switching behavior. A routing table contains Layer 3 routes, DNS information is related to name resolution, and NTP configuration identifies time synchronization settings. Therefore, the MAC address table is the appropriate source when an administrator needs to determine which switch interface has learned a specific MAC address.<\/span><\/p>\n

            Question 146<\/b><\/h3>\n

            An administrator needs to assign a VLAN to a user-facing Ethernet port where only one VLAN should normally be carried. Which port type is appropriate?<\/b><\/p>\n

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

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

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

              An access port is normally configured to carry traffic for one VLAN and is commonly used for end-user devices such as computers, printers, and other Ethernet endpoints. The switch associates untagged traffic arriving on the port with the configured access VLAN. A trunk port is designed to carry multiple VLANs, while a routed port operates at Layer 3. A mirror destination is used for copied traffic analysis rather than normal endpoint connectivity. Therefore, an access port is appropriate when a user-facing interface should belong to a single VLAN.<\/span><\/p>\n

              Question 147<\/b><\/h3>\n

              Which protocol can provide centralized authentication for administrators accessing network infrastructure devices?<\/b><\/p>\n

                \n
              1. DHCP<\/span><\/li>\n
              2. DNS<\/span><\/li>\n
              3. TACACS+<\/span><\/li>\n
              4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

                TACACS+ is commonly used to provide centralized authentication, authorization, and accounting for administrative access to network devices. It allows organizations to manage administrator credentials and permissions through a centralized service instead of maintaining separate local accounts on every device. DHCP provides IP configuration, DNS provides name resolution, and LLDP provides information about directly connected devices. TACACS+ can also support more granular authorization of administrative actions depending on the platform and configuration. Therefore, TACACS+ is the appropriate protocol for centralized administrative authentication.<\/span><\/p>\n

                Question 148<\/b><\/h3>\n

                An administrator wants to identify whether a switch has learned a device’s MAC address through a specific interface. Which command output is most useful?<\/b><\/p>\n

                  \n
                1. NTP status<\/span><\/li>\n
                2. Routing protocol neighbors<\/span><\/li>\n
                3. MAC address table<\/span><\/li>\n
                4. DNS records<\/span><\/li>\n<\/ol>\n

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

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

                  The MAC address table provides the relationship between learned Layer 2 addresses, VLANs, and switch interfaces. Reviewing this information can help an administrator determine where a device is connected or whether its traffic is being learned correctly. Routing protocol neighbor information is used for Layer 3 routing relationships, NTP status concerns clock synchronization, and DNS records provide name-resolution information. Therefore, the MAC address table is the most useful source when identifying the interface through which a particular MAC address has been learned.<\/span><\/p>\n

                  Question 149<\/b><\/h3>\n

                  An Aruba switch needs to send network management information to a monitoring system using a standardized management protocol. Which protocol is appropriate?<\/b><\/p>\n

                    \n
                  1. SNMP<\/span><\/li>\n
                  2. FTP<\/span><\/li>\n
                  3. DHCP<\/span><\/li>\n
                  4. STP<\/span><\/li>\n<\/ol>\n

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

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

                    SNMP is a standard protocol used for monitoring and managing network devices. A network management system can use SNMP to retrieve supported information such as interface statistics, device status, CPU utilization, memory information, and other operational data. SNMP can also support notifications such as traps depending on the implementation. FTP is primarily used for file transfers, DHCP provides IP configuration, and STP prevents Layer 2 loops. Therefore, SNMP is the appropriate protocol when an Aruba switch needs to provide standardized management information to a monitoring platform.<\/span><\/p>\n

                    Question 150<\/b><\/h3>\n

                    A wireless administrator wants to provide a separate wireless network for visitors without allowing normal access to internal corporate resources. Which design is appropriate?<\/b><\/p>\n

                      \n
                    1. Put guests in the employee VLAN<\/span><\/li>\n
                    2. Use a dedicated guest SSID and VLAN<\/span><\/li>\n
                    3. Disable all network segmentation<\/span><\/li>\n
                    4. Assign guests management addresses<\/span><\/li>\n<\/ol>\n

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

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

                      A dedicated guest SSID mapped to a guest VLAN provides logical separation between visitor traffic and corporate users. Security policies can then restrict guest access to internal networks while permitting approved Internet connectivity. Placing guests in the employee VLAN would reduce separation and could expose internal resources unnecessarily. Disabling segmentation removes an important security boundary, and assigning management addresses to guests would not provide the required isolation. Therefore, a dedicated guest SSID and VLAN is an appropriate design for securely providing visitor wireless access.<\/span><\/p>\n

                      Question 151<\/b><\/h3>\n

                      An administrator wants to verify that a Layer 3 device can reach a remote IP address using a basic connectivity test. Which utility should be used?<\/b><\/p>\n

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

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

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

                        Ping uses ICMP echo requests and replies to test basic IP connectivity between network devices. It can help determine whether a destination is reachable and can provide information about response time and packet loss. Ping does not confirm that every application service is functioning, but it is a useful first troubleshooting step. Syslog is used for event logging, SNMP supports monitoring, and LLDP provides neighbor discovery information. Therefore, ping is the appropriate utility for performing a basic Layer 3 reachability test to a remote IP address.<\/span><\/p>\n

                        Question 152<\/b><\/h3>\n

                        An administrator wants to protect a network from a rogue device responding to DHCP requests as an unauthorized server. Which switch feature is designed for this purpose?<\/b><\/p>\n

                          \n
                        1. DHCP snooping<\/span><\/li>\n
                        2. LACP<\/span><\/li>\n
                        3. LLDP<\/span><\/li>\n
                        4. QoS<\/span><\/li>\n<\/ol>\n

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

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

                          DHCP snooping helps protect switched networks against unauthorized DHCP servers by identifying trusted and untrusted interfaces for DHCP traffic. DHCP server responses can be restricted to trusted ports, preventing an unauthorized endpoint from providing incorrect gateway, DNS, or IP configuration information to clients. LACP is used for link aggregation, LLDP provides neighbor information, and QoS controls traffic treatment. DHCP snooping can also create useful binding information for other security mechanisms on supported platforms. Therefore, DHCP snooping is the appropriate feature for reducing the risk of rogue DHCP servers.<\/span><\/p>\n

                          Question 153<\/b><\/h3>\n

                          Which feature can help a network administrator identify the device type and management information of a directly connected neighboring switch?<\/b><\/p>\n

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

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

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

                            LLDP allows compatible network devices to advertise information about themselves to directly connected neighbors. The information can include device identification, interface information, system capabilities, and other supported details. Administrators can use LLDP to help document topology and troubleshoot physical connections between network devices. DHCP is used for IP configuration, RADIUS provides authentication and authorization, and OSPF exchanges routing information between Layer 3 devices. Therefore, LLDP is the appropriate feature for discovering information about a directly connected neighboring switch.<\/span><\/p>\n

                            Question 154<\/b><\/h3>\n

                            An administrator needs to aggregate multiple physical switch interfaces while using a protocol that dynamically negotiates the link aggregation relationship. Which protocol should be used?<\/b><\/p>\n

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

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

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

                              LACP, or Link Aggregation Control Protocol, dynamically negotiates and maintains link aggregation between compatible network devices. Multiple physical interfaces can be combined into a logical link, providing aggregate bandwidth and redundancy. LACP also helps ensure that both ends of the connection agree on the members participating in the aggregation. SNMP provides monitoring, NTP synchronizes clocks, and DNS provides name resolution. Therefore, LACP is the appropriate protocol when an administrator needs dynamically negotiated link aggregation across multiple physical switch interfaces.<\/span><\/p>\n

                              Question 155<\/b><\/h3>\n

                              An administrator wants to apply different network permissions depending on whether a connected user is an employee, contractor, or guest. Which capability is most appropriate?<\/b><\/p>\n

                                \n
                              1. Role-based access control<\/span><\/li>\n
                              2. Port mirroring<\/span><\/li>\n
                              3. NTP<\/span><\/li>\n
                              4. Link aggregation<\/span><\/li>\n<\/ol>\n

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

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

                                Role-based access control allows administrators to assign different network permissions according to a user’s or device’s assigned role. For example, employees may receive access to internal resources, contractors may receive limited access, and guests may be restricted to Internet services. This approach allows security policies to be associated with identities or roles rather than treating every user identically. Port mirroring is used for traffic analysis, NTP synchronizes system clocks, and link aggregation combines physical interfaces. Therefore, role-based access control is the appropriate capability for applying different permissions to different user categories.<\/span><\/p>\n

                                Question 156<\/b><\/h3>\n

                                An administrator wants to reduce the amount of unnecessary multicast traffic delivered to switch ports that do not have interested receivers. Which feature should be enabled?<\/b><\/p>\n

                                  \n
                                1. STP<\/span><\/li>\n
                                2. IGMP snooping<\/span><\/li>\n
                                3. DHCP relay<\/span><\/li>\n
                                4. TACACS+<\/span><\/li>\n<\/ol>\n

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

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

                                  IGMP snooping allows a Layer 2 switch to monitor IGMP membership information and determine which ports have devices interested in specific multicast groups. The switch can then forward multicast traffic selectively instead of sending it unnecessarily to every port in the VLAN. This can improve network efficiency, especially when multicast applications generate significant traffic. STP prevents Layer 2 loops, DHCP relay forwards DHCP messages between networks, and TACACS+ supports centralized administrative authentication. Therefore, IGMP snooping is the appropriate feature for controlling multicast forwarding based on receiver membership.<\/span><\/p>\n

                                  Question 157<\/b><\/h3>\n

                                  An administrator needs to provide reliable power to multiple wireless access points from Ethernet switches. Which consideration is most important when selecting the switch?<\/b><\/p>\n

                                    \n

                                  4. NTP polling interval<\/span><\/li>\n<\/ol>\n

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

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

                                    The PoE power budget determines how much electrical power a switch can provide to connected PoE devices. When deploying multiple wireless access points, the administrator should ensure that the switch has sufficient total PoE capacity and supports the required PoE standards for the access points. DNS cache size does not determine electrical power availability, OSPF area numbers concern routing design, and NTP polling intervals concern time synchronization. Therefore, the PoE power budget is an important consideration when selecting a switch intended to power multiple wireless access points.<\/span><\/p>\n

                                    Question 158<\/b><\/h3>\n

                                    An administrator wants to verify the IP-to-MAC address mapping used by a Layer 3 device for local IPv4 communication. Which information should be examined?<\/b><\/p>\n

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

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

                                      The ARP table contains mappings between IPv4 addresses and corresponding MAC addresses learned or configured by a network device. These mappings allow the device to deliver IPv4 packets to the correct local Ethernet destination. Examining the ARP table can help troubleshoot situations where a device cannot communicate with a local IPv4 neighbor. STP information describes Layer 2 topology, RADIUS data relates to authentication, and Syslog severity controls or describes event logging levels. Therefore, the ARP table is the appropriate information to examine when verifying IPv4-to-MAC address mappings.<\/span><\/p>\n

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

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

                                        NTP allows network devices to synchronize their system clocks with a reliable time source. Accurate time synchronization is important because logs from different devices can then be correlated more effectively. It also supports consistent timestamps for monitoring, troubleshooting, authentication systems, and security investigations. FTP is used for file transfers, DHCP provides IP configuration, and LACP manages link aggregation. Administrators should configure an appropriate NTP server and verify synchronization status. Therefore, NTP is the correct protocol for maintaining accurate device time using an external time source.<\/span><\/p>\n

                                        Question 160<\/b><\/h3>\n

                                        An administrator wants to separate management traffic from ordinary user traffic on a switching infrastructure. Which approach provides logical Layer 2 separation?<\/b><\/p>\n

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

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

                                          A separate management VLAN provides logical Layer 2 separation for network-management traffic. Administrators can place switch management interfaces or other infrastructure management endpoints in a dedicated VLAN and apply access policies that restrict who can reach that network. This separation helps reduce exposure of management services to ordinary user networks. Increasing interface speed does not provide segmentation, disabling STP can introduce Layer 2 loops, and DNS records do not create network separation. Therefore, a separate management VLAN is an appropriate approach for logically isolating management traffic from normal user traffic.<\/span><\/p>\n
