Question 121<\/b><\/h3>\n

An administrator needs to allow only authorized management stations to establish SSH sessions with an Aruba switch. Which approach provides an additional access restriction?<\/b><\/p>\n

    \n
  1. Configure an access control policy for the management source addresses<\/span><\/li>\n
  2. Disable VLAN tagging<\/span><\/li>\n
  3. Increase wireless transmit power<\/span><\/li>\n
  4. Change the NTP polling interval<\/span><\/li>\n<\/ol>\n

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

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

    Restricting SSH access to approved management source addresses provides an additional layer of protection for administrative access. An access control policy can limit which IP addresses or management networks are permitted to establish SSH sessions with the switch. This reduces the exposure of the management interface to unauthorized hosts. VLAN tagging controls Layer 2 traffic, wireless transmit power affects radio coverage, and NTP polling controls time synchronization behavior. Secure authentication should still be used along with source restrictions. Therefore, controlling the permitted management source addresses is an appropriate method for limiting SSH access.<\/span><\/p>\n

    Question 122<\/b><\/h3>\n

    Which Aruba Central object can be used to apply common configuration settings to a collection of similar devices?<\/b><\/p>\n

      \n
    1. MAC address table<\/span><\/li>\n
    2. Group<\/span><\/li>\n
    3. ARP cache<\/span><\/li>\n
    4. Routing table<\/span><\/li>\n<\/ol>\n

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

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

      An Aruba Central group can be used to organize devices and apply common configuration settings to them. This simplifies management when multiple devices require similar policies or operational parameters. Instead of configuring every device individually, administrators can manage shared settings through the appropriate group structure. A MAC address table records learned Layer 2 addresses, an ARP cache stores IP-to-MAC mappings, and a routing table contains Layer 3 forwarding information. These tables do not provide centralized configuration organization. Therefore, a group is the appropriate Aruba Central object for managing common configurations across similar devices.<\/span><\/p>\n

      Question 123<\/b><\/h3>\n

      An administrator wants to identify the physical device connected to a specific switch interface without manually tracing the cable. Which feature should be checked first?<\/b><\/p>\n

        \n
      1. DHCP lease<\/span><\/li>\n
      2. LLDP neighbor information<\/span><\/li>\n
      3. DNS cache<\/span><\/li>\n
      4. NTP status<\/span><\/li>\n<\/ol>\n

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

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

        LLDP neighbor information can identify directly connected network devices and provide useful information about the neighboring device and its connected interface. This makes LLDP particularly useful for documenting physical topology and troubleshooting cabling or port assignments. DHCP leases provide IP address assignment information, DNS caches contain name-resolution records, and NTP status indicates time synchronization. Although LLDP is primarily intended for network device discovery rather than general endpoint identification, it can be highly useful when the connected endpoint supports LLDP. Therefore, LLDP neighbor information should be checked first.<\/span><\/p>\n

        Question 124<\/b><\/h3>\n

        A switch administrator wants two Ethernet links between switches to operate as a single logical connection. Which configuration is required on supported Aruba switches?<\/b><\/p>\n

          \n
        1. LACP link aggregation<\/span><\/li>\n
        2. DHCP snooping<\/span><\/li>\n
        3. Port mirroring<\/span><\/li>\n
        4. Dynamic ARP Inspection<\/span><\/li>\n<\/ol>\n

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

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

          LACP link aggregation combines multiple physical Ethernet interfaces into a logical aggregated connection. This can provide increased aggregate bandwidth and redundancy because traffic can use multiple physical links while the network treats them as one logical interface. Both sides of the connection must have compatible aggregation settings. DHCP snooping protects against unauthorized DHCP servers, port mirroring copies traffic for analysis, and Dynamic ARP Inspection validates ARP traffic. Therefore, LACP link aggregation is the appropriate configuration when multiple Ethernet links need to function as one logical connection.<\/span><\/p>\n

          Question 125<\/b><\/h3>\n

          An administrator wants to prevent an access-layer port from becoming a path for unexpected spanning-tree topology changes when an unauthorized switch is connected. Which feature is appropriate?<\/b><\/p>\n

            \n
          1. SNMP<\/span><\/li>\n
          2. BPDU Guard<\/span><\/li>\n
          3. DHCP relay<\/span><\/li>\n
          4. RADIUS<\/span><\/li>\n<\/ol>\n

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

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

            BPDU Guard is designed to protect edge ports from unexpected Bridge Protocol Data Units. If a BPDU is received on a protected edge port, the configured protective action can be triggered, helping prevent an unauthorized switch from influencing the spanning-tree topology. SNMP is used for monitoring, DHCP relay forwards DHCP messages between networks, and RADIUS provides centralized authentication. BPDU Guard is normally applied where BPDUs are not expected, such as ports connected to end devices. Therefore, BPDU Guard is the appropriate feature for protecting an access-layer edge port.<\/span><\/p>\n

            Question 126<\/b><\/h3>\n

            Which feature helps prevent a Layer 2 network from forwarding frames indefinitely around a physical loop?<\/b><\/p>\n

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

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

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

              Spanning Tree Protocol prevents Layer 2 switching loops by logically blocking redundant paths while keeping them available as alternatives. Ethernet networks can experience broadcast storms, duplicate frames, and MAC-table instability when physical loops exist without an appropriate loop-prevention mechanism. STP calculates a loop-free forwarding topology and can change the active path when network conditions change. RADIUS handles authentication, DHCP provides IP configuration, and SNMP provides monitoring information. Therefore, STP is the technology used to protect a Layer 2 Ethernet network from forwarding loops.<\/span><\/p>\n

              Question 127<\/b><\/h3>\n

              An administrator wants to prevent an endpoint from connecting more devices than permitted through a particular access port. Which feature can enforce a MAC address limit?<\/b><\/p>\n

                \n
              1. Port security<\/span><\/li>\n
              2. NTP<\/span><\/li>\n
              3. OSPF<\/span><\/li>\n
              4. DNS<\/span><\/li>\n<\/ol>\n

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

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

                Port security can be used to control the number or identity of MAC addresses permitted on a switch interface. This is useful on access ports where administrators expect a specific number of authorized devices. Depending on the switch platform and configuration, an administrator can define a maximum MAC address count and specify an action when the limit is exceeded. NTP handles time synchronization, OSPF performs dynamic routing, and DNS provides name resolution. Therefore, port security is the appropriate feature for enforcing MAC address limits on an access interface.<\/span><\/p>\n

                Question 128<\/b><\/h3>\n

                An Aruba access point needs electrical power through its Ethernet connection instead of a separate local power adapter. Which technology provides this capability?<\/b><\/p>\n

                  \n
                1. OSPF<\/span><\/li>\n
                2. LLDP<\/span><\/li>\n
                3. PoE<\/span><\/li>\n
                4. Syslog<\/span><\/li>\n<\/ol>\n

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

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

                  Power over Ethernet, or PoE, allows compatible devices such as wireless access points to receive electrical power through Ethernet cabling. The same cable can carry both network traffic and electrical power, simplifying installation where electrical outlets are not conveniently located. The switch must support the required PoE standard and provide sufficient power for the connected device. OSPF is a routing protocol, LLDP provides neighbor information, and Syslog is used for centralized event logging. Therefore, PoE is the appropriate technology when an access point needs to receive power through its Ethernet connection.<\/span><\/p>\n

                  Question 129<\/b><\/h3>\n

                  An administrator needs dynamic routing between Layer 3 Aruba switches and wants the devices to exchange link-state information. Which protocol should be considered?<\/b><\/p>\n

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

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

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

                    OSPF is a link-state routing protocol that enables Layer 3 devices to dynamically exchange routing information. OSPF routers establish neighbor relationships and exchange link-state information, allowing each router to build a topology database and calculate appropriate routes. This reduces the need for manually configured static routes in larger networks. FTP handles file transfers, DHCP provides IP configuration, and SNMP provides monitoring and management information. Therefore, OSPF should be considered when Aruba Layer 3 switches need to dynamically exchange link-state routing information.<\/span><\/p>\n

                    Question 130<\/b><\/h3>\n

                    A network uses redundant Layer 2 links, and the administrator wants to ensure that only one logical forwarding path is active while another remains available as a backup. Which technology provides this behavior?<\/b><\/p>\n

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

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

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

                      STP is designed to create a loop-free logical topology when redundant Layer 2 paths exist. It can place selected interfaces into a non-forwarding state while keeping redundant paths available for recovery. If the active path fails, STP can recalculate the topology and allow an alternate path to forward traffic. RADIUS provides authentication, SNMP provides network monitoring, and DHCP supplies IP configuration. Therefore, STP provides the required behavior when redundant Layer 2 links must exist without creating an active forwarding loop.<\/span><\/p>\n

                      Question 131<\/b><\/h3>\n

                      An administrator wants to use an Aruba Central environment to monitor the operational status of managed switches and access points from a centralized interface. Which capability supports this requirement?<\/b><\/p>\n

                        \n
                      1. Centralized cloud management<\/span><\/li>\n
                      2. Local ARP resolution<\/span><\/li>\n
                      3. Static MAC learning<\/span><\/li>\n
                      4. Console-only administration<\/span><\/li>\n<\/ol>\n

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

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

                        Centralized cloud management allows administrators to monitor and manage supported network infrastructure through a centralized management platform. Aruba Central can provide visibility into managed devices, configuration status, alerts, and operational information depending on the device type and licensed capabilities. Local ARP resolution is used for IP-to-MAC mapping, static MAC learning concerns Layer 2 forwarding behavior, and console-only administration requires direct device access. Therefore, centralized cloud management is the appropriate capability when administrators need centralized operational visibility across managed Aruba devices.<\/span><\/p>\n

                        Question 132<\/b><\/h3>\n

                        An administrator needs to copy a switch configuration or operational information to a remote system using a simple file-transfer protocol. Which protocol may be used for basic file transfers?<\/b><\/p>\n

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

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

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

                          TFTP, or Trivial File Transfer Protocol, provides a simple file-transfer mechanism commonly used in network environments for certain configuration or firmware-related tasks where supported. It has fewer features and less security than protocols such as SFTP or SCP, so its use should be appropriate for the specific environment and platform capabilities. OSPF handles dynamic routing, RADIUS provides centralized authentication, and LLDP provides neighbor discovery. Therefore, TFTP is the protocol among these options designed for basic file transfers in supported network-management scenarios.<\/span><\/p>\n

                          Question 133<\/b><\/h3>\n

                          A network administrator wants to monitor traffic statistics on interfaces without capturing the complete packet contents. Which technology can provide sampled traffic information?<\/b><\/p>\n

                            \n
                          1. sFlow<\/span><\/li>\n
                          2. DHCP<\/span><\/li>\n
                          3. STP<\/span><\/li>\n
                          4. RADIUS<\/span><\/li>\n<\/ol>\n

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

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

                            sFlow provides sampled traffic information that can be used to analyze network traffic patterns without requiring every packet to be captured and processed in full. It can help administrators understand bandwidth utilization, traffic sources, destinations, and application-related patterns depending on the available monitoring system. DHCP manages IP address configuration, STP prevents Layer 2 loops, and RADIUS provides centralized authentication. sFlow is therefore useful for traffic visibility and capacity analysis when full packet capture is unnecessary or impractical.<\/span><\/p>\n

                            Question 134<\/b><\/h3>\n

                            An administrator wants to prevent broadcast or unknown traffic from consuming excessive network resources on a switch. Which feature can help control excessive traffic levels?<\/b><\/p>\n

                              \n
                            1. NTP<\/span><\/li>\n
                            2. Storm control<\/span><\/li>\n
                            3. DNS<\/span><\/li>\n
                            4. RADIUS<\/span><\/li>\n<\/ol>\n

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

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

                              Storm control can help limit excessive broadcast, multicast, or unknown-unicast traffic on supported switch interfaces. This can reduce the impact of abnormal traffic conditions that might otherwise consume significant bandwidth and network resources. Administrators can configure appropriate thresholds based on the network design and platform capabilities. NTP synchronizes time, DNS provides name resolution, and RADIUS provides centralized authentication and authorization. Therefore, storm control is the appropriate feature when the objective is to limit excessive Layer 2 traffic and reduce the potential impact of a traffic storm.<\/span><\/p>\n

                              Question 135<\/b><\/h3>\n

                              An administrator wants to protect an access port by ensuring that an unexpected spanning-tree root device cannot influence the network through that port. Which feature can help protect the intended STP hierarchy?<\/b><\/p>\n

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

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

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

                                Root Guard can help protect the intended spanning-tree hierarchy by preventing a port from becoming an alternate path toward an unexpected root bridge. It is useful on interfaces where administrators do not expect a connected device to influence root bridge selection. If superior BPDUs are received on a protected interface, the configured protection mechanism can place the port into an appropriate state rather than allowing the unexpected device to become part of the intended root topology. DHCP provides IP configuration, SNMP supports monitoring, and FTP transfers files. Therefore, Root Guard is the appropriate STP protection feature.<\/span><\/p>\n

                                Question 136<\/b><\/h3>\n

                                An administrator needs a secure protocol for transferring files between a management workstation and an Aruba network device. Which option provides encrypted file transfer when supported?<\/b><\/p>\n

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

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

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

                                  SCP, or Secure Copy Protocol, provides encrypted file transfer over an SSH-based secure session. It can be used when supported by the network platform for transferring configuration files or other supported files securely. TFTP does not provide encryption, FTP by itself does not provide equivalent encryption, and Telnet is an interactive management protocol rather than a secure file-transfer mechanism. Secure file transfer is particularly important when configuration files or other sensitive management information are involved. Therefore, SCP is the appropriate option when encrypted file transfer is required and supported.<\/span><\/p>\n

                                  Question 137<\/b><\/h3>\n

                                  Which protocol is commonly used to resolve a domain name into an IP address?<\/b><\/p>\n

                                    \n
                                  1. DNS<\/span><\/li>\n
                                  2. STP<\/span><\/li>\n
                                  3. LACP<\/span><\/li>\n
                                  4. LLDP<\/span><\/li>\n<\/ol>\n

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

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

                                    The Domain Name System, or DNS, translates human-readable domain names into IP addresses and can also provide other name-related information. When a client needs to communicate with a service using a domain name, it can query a DNS server to determine the corresponding address. STP prevents Layer 2 loops, LACP manages link aggregation, and LLDP provides information about directly connected network devices. Therefore, DNS is the appropriate protocol for resolving domain names into IP addresses.<\/span><\/p>\n

                                    Question 138<\/b><\/h3>\n

                                    An administrator wants to make configuration changes through a centralized Aruba management platform while maintaining consistent policies across multiple sites. Which approach is appropriate?<\/b><\/p>\n

                                      \n
                                    1. Configure every interface independently<\/span><\/li>\n

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

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

                                      Centralized configuration management allows administrators to maintain consistent settings across multiple managed devices and sites. It can reduce repetitive manual changes and improve configuration consistency when similar policies must be applied to many devices. Aruba Central provides centralized management capabilities for supported devices, allowing administrators to organize infrastructure and apply appropriate configuration settings. Configuring every interface independently increases administrative effort, while disabling synchronization or removing device groups reduces centralized management capabilities. Therefore, centralized configuration management is the appropriate approach for maintaining consistent policies across multiple sites.<\/span><\/p>\n

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

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

                                        NTP configuration should be reviewed when network devices show inconsistent system times. NTP allows devices to synchronize their clocks with a reliable time source, making logs and event timestamps easier to correlate across the infrastructure. Accurate time is especially important for troubleshooting, monitoring, authentication systems, and security investigations. DHCP scopes control IP address allocation, VLAN tagging identifies traffic belonging to VLANs, and MAC address limits control permitted Layer 2 addresses. Therefore, NTP configuration is the relevant area to investigate when device clocks are not synchronized.<\/span><\/p>\n

                                        Question 140<\/b><\/h3>\n

                                        An administrator needs to provide different traffic treatment for voice and ordinary data applications based on their service requirements. Which network capability should be used?<\/b><\/p>\n

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

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

                                          Quality of Service, or QoS, allows network traffic to be classified and handled according to defined priorities or service requirements. Voice traffic is often sensitive to delay, jitter, and packet loss, so QoS policies can help provide appropriate treatment when network resources become congested. QoS may use mechanisms such as classification, marking, queuing, and scheduling. ARP resolves IPv4 addresses to MAC addresses, DHCP provides IP configuration, and DNS provides name resolution. Therefore, QoS is the appropriate capability when different applications require different traffic treatment.<\/span><\/p>\n
