HPE ARUBA NETWORKING CERTIFIED PROFESSIONAL - SWITCHING Exam HPE7-A08 Questions V11.02 HPE Aruba Networking Certified Professional - Switching Topics - HPE Network Switching Professional Exam HPE7-A08 Exam Questions (2026) - Improve Your Confidence 1.Refer to the partial exhibit from an HPE Aruba Networking CX 8325: A new port 1/1/44 needs to be configured to connect to a 29301, which has the following configuration: Which configuration would be used? A) B) HPE7-A08 Exam Questions (2026) - Improve Your Confidence C) D) A. Option A B. Option B C. Option C D. Option D Answer: A Explanation: The question relates to configuring port 1/1/44 on an Aruba CX 8325 switch to connect to a 2930F switch (Aruba 2930F series). The key factor is interoperability between these two devices, especially regarding link aggregation and port channel settings. The Aruba 2930F typically uses static or LACP link aggregation with standard settings. To connect an Aruba CX 8325 port to a 2930F port, the CX configuration must align with the 2930F settings, particularly regarding: Enabling LACP (Link Aggregation Control Protocol) on the port. Correct VLAN tagging or trunk mode. Matching speed and duplex settings. From the options given, answer A corresponds to enabling LACP with appropriate trunk configuration that matches the 2930F. The other options either have mismatches in aggregation or trunking mode or missing LACP.

HPE7-A08 Exam Questions (2026) - Improve Your Confidence 2.OSPF peering is configured between HPE Aruba Networking CX 6300 switches utilizing BFD. You've made this configuration on switch B, while switch A is in the default configuration: Which BFD Tx/Rx interval values will switch A use for the show bfd session? A. Switch A show BFD sessions using 500ms B. Switch A show BFD sessions using 6000ms C. Switch A show BFD sessions using 2000ms D. Switch A show BFD sessions using 300ms Answer: C Explanation: This question involves OSPF peering configured between CX 6300 switches using BFD (Bidirectional Forwarding Detection). BFD parameters include transmit (Tx) and receive (Rx) intervals. Switch B has custom BFD interval values configured, but switch A is at default configuration. According to Aruba CX default BFD parameters, the Tx and Rx intervals default to 2000ms (2 seconds). This is why switch A’s show BFD session displays intervals of 2000ms even if switch B uses different values. BFD interval negotiation results in the highest Tx/Rx interval being used, or default in case one side is unconfigured.

HPE7-A08 Exam Questions (2026) - Improve Your Confidence What is the reason for this? A. A loopback interface hasn't been configured on Agg-2 B. OSPF interfaces are passive by default C. A different OSPF process ID is used on each switch D. A Layer-3 interface has not been associated with a VRF Answer: D Explanation: The question concerns an OSPF configuration where the interface does not come up as expected. Common reasons for no OSPF adjacency or interface participation include: Interfaces being passive (no adjacency formed) Mismatched OSPF process IDs Missing loopback interfaces (for router ID) Layer-3 interfaces not associated with VRFs when VRFs are configured Option D (a Layer-3 interface has not been associated with a VRF) is the root cause because in Aruba CX switches, when VRF is configured, all Layer-3 interfaces that HPE7-A08 Exam Questions (2026) - Improve Your Confidence participate in OSPF must be associated with the correct VRF instance to establish adjacency and participate correctly. If an interface is not part of the VRF configured for OSPF, it will not appear in the OSPF interface list or form neighbors. Reference: ArubaOS-CX VRF and OSPF configuration guides OSPF troubleshooting guides on Aruba CX switches Aruba Network Design Best Practices documents 4.You need to run a packet capture on a CX switch and be able to view the full output on a remote device in real-time. What is the best way to do this? A. Configure a mirror session using ERSPAN to a computer running Wireshark B. Inspect the summary of the packets in real time on the switch using tcpdump C. Configure a mirror session with another port on the switch as the destination D. Configure a mirror session to the CPU, use tshark to capture it to a PCAP file Answer: A Explanation: To capture packets on an HPE Aruba CX switch and view the output remotely in real- time, the best practice is to use a mirror session that forwards traffic to a remote device running a packet analyzer such as Wireshark. ERSPAN (Encapsulated Remote Switched Port Analyzer) allows the mirror traffic to be encapsulated in GRE and sent over an IP network to a remote monitoring station. This method ensures full packet capture with no local resource constraints and provides full visibility to the analyst. Option B (using tcpdump on the switch) only provides summarized or limited capture locally. Option C (mirroring to another switch port) only allows local monitoring and does not provide remote real-time viewing. Option D (mirror to CPU and then use tshark) is less efficient and may be resource- intensive on the switch. Therefore, configuring ERSPAN to a remote Wireshark host is the recommended and best way. Reference: HPE Aruba CX Switch Documentation C Packet Capture and ERSPAN configuration guide ArubaOS-CX Configuration Guide, Monitoring and Troubleshooting Chapter 5.When configuring a multicast solution on HPE Aruba Networking CX switches, what needs to be configured on the access switch to enable efficient traffic flow? A. PIM on VLAN B. IGMP-snooping on VLAN C. IGMP on VLAN HPE7-A08 Exam Questions (2026) - Improve Your Confidence D. IGMP-snooping on SVI Answer: B Explanation: For multicast to function efficiently on Aruba CX access switches, IGMP snooping needs to be enabled on the VLAN interfaces. IGMP snooping listens to IGMP join and leave messages between multicast clients and routers to allow the switch to forward multicast traffic only to interested ports, reducing unnecessary multicast flooding. PIM is a multicast routing protocol and usually configured on routing devices, not access switches. IGMP (without snooping) enables hosts to signal interest but does not control traffic forwarding at the switch layer. Enabling IGMP snooping on SVI alone may not be sufficient; it should be enabled on VLANs that carry multicast clients. Hence, enabling IGMP snooping on VLAN is necessary for efficient multicast traffic flow.

You would like to configure a common first-hop redundancy protocol as part of your migration strategy. Which of these would be suitable? A. Active Forwarding B. HSRP C. VRRP D. Active Gateway Answer: C Explanation: When deploying HPE Aruba VSX switches parallel to existing HPE Comware switches, choosing a first-hop redundancy protocol compatible with both platforms is essential. VRRP (Virtual Router Redundancy Protocol) is widely supported across multiple vendors and is suitable for multi-vendor environments. HSRP is Cisco proprietary and not supported on Aruba Comware or CX. Active Forwarding and Active Gateway are Aruba VSX internal mechanisms, not standard first-hop redundancy protocols. VRRP provides seamless failover and is supported in Comware and Aruba CX platforms. Thus, VRRP is the suitable choice.

VSX secondary switch is down. B. VSX keepalive has detected that the secondary member is down. C. The multichassis LAG 2 interface is down on both switches. D. The physical interface of LAG 2 on the secondary VSX member is down. Answer: A Explanation: The event message: perl Copy 2024-04-04T08:35:38.312254+00:00 ICX-Core-1 hpe-vaxd[2167]: Event[701|LOG_INFO|AMM1/1|VSX2 state local up, remote down] indicates that the local VSX member is up, but the remote VSX member is down. In a VSX pair, both switches must be operational for full redundancy and synchronization. This log means the secondary VSX switch (remote) is down or unreachable, causing loss of synchronization and possibly traffic failover issues. Option B (keepalive detection) is related but the event specifically shows the state of the remote switch being down. Options C and D refer to LAG or interface state, which are not what this log entry describes.

How can you back up the saved switch configuration to a remote location? A. Use the command copy startup-config scp://user@192.168.1.100/switch_config.cfg vrf default on the switch. B. Use the command scp admin@192.168.1.200:/running-config on the SFTP server. C. Use the command copy startup-config sftp://user@192.168.1.100/switch_config.cfg vrf mgmt on the switch. D. Use the command scp admin@192.168.1.200:/startup-config on the SFTP server. Answer: C Explanation: Backing up the switch configuration to a remote Linux SFTP server requires using the copy command with the correct protocol (SFTP in this case), username, server IP, filename, and optionally the VRF to route management traffic. HPE7-A08 Exam Questions (2026) - Improve Your Confidence Option A uses SCP and vrf default but the question mentions SFTP server, so SFTP protocol should be used. Option B is a server-side command (not the switch). Option C correctly uses copy startup-config sftp://user@192.168.1.100/switch_config.cfg vrf mgmt which backs up the startup- config via SFTP using the management VRF. Option D is also a server-side command. Using vrf mgmt is required because the management IP is in a separate VRF on CX switches.

A. Leave and Report B. Join, Leave, Query and Report C. Query and Report D. Join and Query Answer: B Explanation: HPE7-A08 Exam Questions (2026) - Improve Your Confidence IGMP (Internet Group Management Protocol) supports several message types: Join, Leave, Query, and Report messages to manage multicast group membership. Join messages indicate a host wants to join a multicast group. Leave messages indicate a host is leaving a multicast group. Query messages are sent by routers to discover group members. Report messages are sent by hosts to indicate membership. Therefore, the full set of IGMP message types supported includes Join, Leave, Query, and Report. Options with only Leave and Report or only Join and Query are incomplete.

Which will you need to configure to meet this requirement? A. VRRP B. VNBT C. VSF D. VRF Answer: B Explanation: Colorless ports allow network devices to move or replace endpoints without changing port-level configurations, typically by automatically assigning network policies dynamically to any port. HPE Aruba’s solution for colorless ports is the VNBT (Virtual Network Boundary Tagging) feature. VNBT allows dynamic segmentation of traffic, so ports can automatically take on the policies assigned to devices regardless of physical port location. VRRP is a first-hop redundancy protocol and unrelated to port colorlessness. VSF (Virtual Switching Framework) is for switch stacking. VRF (Virtual Routing and Forwarding) is for traffic segmentation. Thus, VNBT is the correct feature to meet colorless port requirements. Reference: Aruba Dynamic Segmentation and VNBT Whitepapers ArubaOS-CX User Guide for Dynamic Segmentation Aruba Tech Docs on Colorless Ports and VNBT 11.An Aruba CX B100 VSX has the following state for LACP: 2024-06-08T19:48:34.713434+03:00 VSX1 lacpd[837]: Event|1321|LOG_INFO|AMM|1/1|LAG 253 State change for interface 1/1/25:3: Actor state: ALFNCD, Partner state: ASFNCD 2024-06-06T19:48:34.675496+03:00 VSX1 lacpd[837]: HPE7-A08 Exam Questions (2026) - Improve Your Confidence Event|1308|LOG_INFO|AMM|1/1|LACP rate set to slow for LAG 253 What can be observed based on the output? A. The LAG 253 has a mismatching configuration with a peer B. The global LACP rate has been configured for LACP ports C. The LAG 253 has been negotiated automatically with peer timeout values D. The local LAG 253 has a matching LACP configuration with peer Answer: D Explanation: The LACP state event Actor state: ALFNCD, Partner state: ASFNCD indicates that the LACP negotiation between the local (actor) and peer (partner) is successful with all flags matching and no errors. ALFNCD and ASFNCD are standard LACP states indicating Active, Long timeout, Aggregation capable, Not synchronized, Collecting, and Distributing flags set as expected. Also, the log shows the LACP rate is set to slow, which is the default. Thus, the output shows the LAG 253 has a matching LACP configuration with its peer.

What would be the impact of changing the network type to point-to-point? A. It will reduce the number of LSA type-2 advertisements B. A larger number of OSPF routes would be supported C. It will increase the number of LSA type-3 advertisements D. The configuration would remain as the default Answer: A Explanation: When configuring OSPF on a point-to-point network type (typically a direct link between two routers), OSPF treats the link as a broadcast-less point-to-point segment. This reduces unnecessary OSPF overhead by eliminating the need for: DR/BDR elections (which generate LSA Type 2 advertisements for broadcast multi- access networks). Thus, changing network type to point-to-point reduces the number of LSA Type-2 advertisements, which are used to describe the network segment in multi-access environments. No impact on number of routes (LSA Type-3 is about inter-area routes). The default is usually broadcast or point-to-multipoint depending on interface.

What is required when establishing peering with neighboring devices using eBGP that are not directly connected? A. Use of next-hop-self B. Use of ebgp-multihop C. Use of route-reflector D. Use of address-family ipv4 external Answer: B Explanation: When establishing eBGP peering between devices that are not directly connected, the TTL (Time To Live) value of the BGP packets must be increased to allow them to traverse multiple hops. This is achieved by configuring ebgp-multihop, which increases the TTL beyond the default value of 1. next-hop-self changes the BGP next-hop attribute but is not required for multihop eBGP. route-reflector is a BGP design feature unrelated to multihop. address-family ipv4 external is not a standard command on Aruba CX switches. Therefore, to successfully peer eBGP sessions across multiple hops, ebgp-multihop must be configured. Reference: ArubaOS-CX BGP Configuration Guide RFC 4271 (BGP-4) HPE Aruba Networking Best Practices for BGP 14.Your customer's CX switches are managed in HPE Aruba Networking Central. If a VSX primary switch is accidentally powered off, which alert will be triggered? A. Switch Reboot B. Switch Stack Conductor Change C. Switch Disconnected D. Switch STP Root Change Answer: C Explanation: When a VSX primary switch is powered off, it loses connectivity with management systems such as HPE Aruba Central. This causes the management system to trigger a "Switch Disconnected" alert because the switch is no longer reachable. "Switch Reboot" alerts would indicate a restart, not power off. "Switch Stack Conductor Change" refers to stack leadership changes, not VSX primary down. "Switch STP Root Change" relates to Spanning Tree Protocol root bridge changes. HPE7-A08 Exam Questions (2026) - Improve Your Confidence Hence, powering off the VSX primary causes a "Switch Disconnected" alert.

A. XML B. YAML C. JSON D. SOAP Answer: C Explanation: The Aruba CX switches REST API supports the JSON (JavaScript Object Notation) data format for both requests and responses. JSON is widely adopted for REST APIs due to its lightweight and readable format. XML and YAML are not supported for REST API on CX switches. SOAP is a different protocol not used by Aruba CX REST API. Therefore, JSON is the correct and supported data format.

You are concerned that the high CPU could be affecting users. What should you do to restore service as quickly as possible? A. Reboot the switch. B. Revert the change. C. Disable debug logging. D. Pause NAE monitoring. Answer: B Explanation: Comprehensive Detailed Explanation When a recent configuration change causes a spike in CPU utilization that negatively impacts users, the fastest way to restore normal operation is to revert the change. This rollback immediately removes the offending configuration, potentially stabilizing the CPU and restoring service. Rebooting the switch (Option A) is disruptive and takes more time. Disabling debug logging (Option C) may help if debug is causing high CPU, but it doesn't undo config changes. Pausing NAE monitoring (Option D) only suspends monitoring and doesn’t address HPE7-A08 Exam Questions (2026) - Improve Your Confidence the root cause. Hence, reverting the recent config change is the best immediate action.

Which feature would allow you to use a single subnet for the wired guests, allowing them to utilize only default gateway services and communicate with each other in a conference room but not elsewhere? A. By assigning the guest users in the conference room to an isolated VLAN and the gateway to a primary VLAN. B. By assigning the guest users in the conference room to a community VLAN and the gateway to a primary VLAN. C. By assigning the guest users in the conference room to a primary VLAN and the gateway to an isolated VLAN. D. By assigning the guest users in the conference room to an isolated VLAN and the gateway to a community VLAN. Answer: B Explanation: In a hotel environment where a single subnet is used for wired guests, but guest devices in a conference room need to communicate with each other (and with the default gateway), while remaining isolated from other guests elsewhere, Community VLANs are appropriate. Community VLANs allow hosts within the same VLAN community to communicate with each other and the default gateway but are isolated from hosts in other communities. Isolated VLANs block communication between ports and only allow communication to the gateway. Therefore, assigning conference room guests to a community VLAN and the gateway to a primary VLAN allows the desired communication model.

What could cause this? A. The switch is still pending authorization on the organization settings page. B. Only switches with factory default config can be added to a group with existing config. HPE7-A08 Exam Questions (2026) - Improve Your Confidence C. Configuration auto-commit has been disabled for the group in HPE Aruba Networking Central. D. The switch is configured in a VSX pair, which HPE Aruba Networking Central does not support. Answer: B Explanation: When adding a switch with an existing configuration into a group in Aruba Central, the group requires devices to have factory default configurations to allow Central to apply the group config correctly. If the switch has an existing configuration, synchronization and auto-commit may fail because of configuration conflicts. Option A: Pending authorization is unrelated to config synchronization. Option C: Auto-commit can be disabled but does not block syncing existing config. Option D: VSX support limitations are irrelevant here. Therefore, the likely cause is that only switches with factory default config can be added to a group with existing config.

You are implementing the setup in Building A and C. The actual fiber distance between the building locations is 200m / 656ft utilizing OM4 cabling. What needs to be changed in the configuration based on the actual environmental conditions to complete the installation and 7 other CX 6300 VSF stack connections in the future? A. Replace the 25GR optics with 10SR B. Replace the 25GR optics with 25LR C. Replace the 25GR optics with 10LR D. Replace the 25GR optics with 25SR Answer: D Explanation: The configuration involves connecting two buildings over fiber using OM4 cabling with a distance of 200 meters. The current optics in use are 25GR (25 Gigabit Rate) optics. For multimode fiber such as OM4, SR (Short Reach) optics are suitable for distances up to 300 meters. HPE7-A08 Exam Questions (2026) - Improve Your Confidence In contrast, LR (Long Reach) optics are typically designed for single-mode fiber and longer distances. Therefore, to properly support the 200m OM4 fiber link, 25SR optics should be used instead of 25GR (which are often long-reach optics). 10SR and 10LR refer to 10Gbps optics, which do not meet the 25Gbps requirement. 25LR optics are for single-mode fiber and longer distances, not multimode.

Which AOS-CX command allows you to roll back your change if the ACL change is wrongly formed and you can no longer log in to the switch? A. Use the checkpoint commit command after you commit the change. B. Use the checkpoint auto command before you commit the change. C. Use the checkpoint auto command after you commit the change. D. Use the checkpoint commit command before you commit the change. Answer: B Explanation: When making changes remotely to critical configurations such as Control Plane ACLs on a CX switch, to protect against accidental lockout due to misconfiguration, you should enable checkpoint auto before committing the changes. Checkpoint auto creates an automatic rollback timer. If the administrator loses connectivity (e.g., because of the ACL change), the system automatically rolls back the change after the timer expires, preventing lockout. checkpoint commit is used after committing to save the checkpoint explicitly, but it does not provide automatic rollback. Running checkpoint auto before committing is essential to have the rollback safety net.

A. Enable dhcpv4-snooping trust 10.100.100.10 on VLAN 30 B. Enable dhcpv4-snooping authorized-server 10.100.100.10 on VLAN 30 C. Enable snooping globally and on VLAN 30 D. Enable dhcpv4-snooping globally and on interface VLAN 30 Answer: B Explanation: To prevent rogue DHCP servers in a VLAN, DHCP snooping authorized-server commands are used to specify trusted DHCP servers allowed to respond. Option A (dhcpv4-snooping trust 10.100.100.10) configures a trusted port, but it is not VLAN specific and not precise enough for this purpose. Enabling DHCP snooping globally and on VLAN or interface (Options C and D) are prerequisites but do not prevent rogue servers unless authorized servers are defined. HPE7-A08 Exam Questions (2026) - Improve Your Confidence Option B correctly enables an authorized DHCP server IP on VLAN 30, blocking unauthorized DHCP responses.

Which configuration on the switch should you verify? A. SNMP community string B. User-role configuration C. HTTPS client certificate D. Trust Anchor profile Answer: D Explanation: When troubleshooting downloadable user roles (DUR) between Aruba CX switches and ClearPass, it is crucial to verify the Trust Anchor profile on the switch. The Trust Anchor profile contains the certificates and keys that allow secure communication and authentication with ClearPass, ensuring the switch can validate the RADIUS server and downloaded user role information. SNMP community string (Option A) is unrelated to DUR. User-role configuration (Option B) is important but verifying trust anchor ensures secure role downloads. HTTPS client certificate (Option C) is not typically part of DUR authentication. Therefore, the Trust Anchor profile must be verified.

What needs to be done to remove the LACP block state? A. On one of the switches, change the LACP mode to passive B. Change the LACP mode from passive to active on one of the switches C. Change the LACP mode from passive to static on one of the switches D. On both of the switches, change the LACP timeout to short HPE7-A08 Exam Questions (2026) - Improve Your Confidence Answer: B Explanation: LACP (Link Aggregation Control Protocol) modes can be active or passive. When two switches are both configured in passive mode, no LACP packets are initiated, causing the link aggregation to fail or go into a block state. Changing one side from passive to active causes that switch to initiate LACP negotiation, resolving the block state. Changing to static mode disables LACP negotiation, which is not recommended unless both sides are static. Changing timeout does not solve LACP block issues caused by mode mismatches. Therefore, changing one switch’s LACP mode from passive to active is necessary to resolve the block.

A. The ISL traffic is always tagged with EF QoS markings. B. The traffic over the ISL is encapsulated as a GRE tunnel. C. The ISL LAG automatically includes all configured VLANs. D. The ISL LAG must allow all configured VLANs. Answer: D Explanation: In VSX architecture, the Inter-Switch Link (ISL) is implemented as a Link Aggregation Group (LAG). To ensure proper forwarding and VLAN consistency, the ISL LAG must allow all configured VLANs. This allows VSX synchronization and data forwarding across all VLANs that span the two switches. ISL traffic is not specifically tagged with EF QoS markings by default. ISL traffic is not encapsulated in GRE tunnels. The ISL LAG does not automatically include all VLANs; VLANs must be allowed on the LAG explicitly. Hence, the LAG must be configured to allow all VLANs.
