HP HPE Network Switching Associate Exam HPE6-A86 Exam Dumps: Updated Questions & Answers (June 2026)

The correct answer is B. PoE is disabled on the interface. If there are no lights on the access point, the first issue to investigate is whether the AP is receiving power. HPE Aruba Networking 550 Series installation documentation identifies Power over Ethernet as a supported power source for the AP, including IEEE 802.3bt or 802.3at PoE. HPE Aruba Networking AOS-CX documentation for the CX 6000/6100 PoE command shows that per-interface power distribution can be enabled with power-over-ethernet and disabled with no power-over-ethernet. If PoE is disabled on the switch interface, the AP will not receive power from the Ethernet cable and therefore may show no LEDs. Option A is incorrect because a missing STP configuration would not prevent the AP from powering on. Option C is incorrect because failure to reach HPE Aruba Networking Central would occur after the AP is powered and network-connected. Option D is also incorrect because a wrong VLAN can prevent management or provisioning, but it would not normally stop the AP LEDs from turning on.

The correct answer is D. A DHCP server needs to be configured with the required options. HPE Aruba Networking AOS-CX documentation for the 4100i, 6000, and 6100 switch series states that ZTP supports standards-based Zero Touch Provisioning and that the DHCP server must be configured to provide the required ZTP server information. The documentation lists supported DHCP options, including vendor-specific option 43, and explains that the switch contacts a DHCP server when it boots from a factory-default configuration. HPE Aruba documentation also explains that a trusted-network ZTP setup uses a TFTP server for configuration and image files, with the DHCP server providing the required information for the switch to find those files. Therefore, DHCP options are the required foundation for ZTP. Option A is misleading because ZTP is tied to a factory-default boot state, not simply being enabled on the management interface. Option B is incorrect because SCP is not the documented ZTP download method here. Option C is incorrect because the guide describes TFTP, not SFTP, for this ZTP workflow.

The correct answer is D. QoS. Poor call quality during network congestion is commonly caused by delay, jitter, or packet loss affecting real-time voice and video traffic. HPE Aruba Networking AOS-CX Quality of Service documentation explains that QoS allows administrators to customize how different traffic types are serviced based on their characteristics and importance. QoS helps keep important traffic moving at an acceptable speed regardless of current bandwidth usage. HPE Aruba documentation also states that VoIP traffic is delay and jitter sensitive and should receive priority service for optimum transmission. Microsoft Teams voice and video traffic is latency-sensitive, so configuring QoS is the correct approach to prioritize this traffic when the network is busy. Option A, CoS, is a specific Layer 2 priority marking method that can be part of a QoS design, but the broader feature to configure is QoS. Option B, ZIP, is not relevant. Option C, IGMP, is used for multicast group management and does not solve general Teams call-quality issues.

The correct answer is A. API. HPE Aruba Networking Fabric Composer is an orchestration and management platform for supported AOS-CX switches. HPE Aruba Networking Fabric Composer documentation describes Fabric Composer as managing and orchestrating HPE Aruba Networking AOS-CX switch fabrics and includes an API Explorer containing Fabric Composer API documentation. The Fabric Composer guide also describes system settings for switch polling, switch events through a web socket connection, and enhanced logging of API calls. This aligns with Fabric Composer using API-based communication and orchestration rather than traditional CLI-only management. SSH can be used for direct administrator access to a switch, but it is not the best answer for Fabric Composer’s switch-management communication method. Telnet is insecure and not appropriate. SNMPv3 is useful for secure monitoring, but it is not the protocol used by Fabric Composer for configuration orchestration of CX switches. Therefore, the correct option is API.

The correct answer is C. No, SSH and HTTPS are enabled by default. HPE Aruba Networking AOS-CX hardening documentation states that, in the factory-default state, AOS-CX switches have SSH enabled on TCP port 22 and Web UI/read-write REST API enabled on TCP port 443. For the CX 6200 switch series, these services are enabled on both the default and management VRFs. These are secure management protocols because SSH encrypts CLI sessions and HTTPS encrypts web-management sessions. The same HPE Aruba guidance also notes that connections to TCP port 80 are automatically redirected to TCP port 443, which means HTTP is not used as the insecure management method. Option A is incorrect because Telnet is insecure and is not the correct default secure management protocol. Option B is incorrect because Telnet is not the default management method. Option D is incorrect because HTTP connections are redirected to HTTPS. ( arubanetworking.hpe.com )

The correct answer is C. The existing 5406R configuration uses an LACP trunk, with VLANs 100, 200, and 300 tagged and VLAN 50 untagged. The equivalent HPE Aruba Networking AOS-CX configuration is to create a LAG, enable LACP using lacp mode active, allow the tagged VLANs on the trunk, and configure VLAN 50 as the native VLAN. In AOS-CX, the vlan trunk native < VLAN-ID > command assigns the native VLAN to the trunk or LAG interface. Native VLAN traffic is untagged unless native VLAN tagging is specifically configured. HPE Aruba documentation also shows the command syntax for assigning native VLANs to LAG interfaces and the use of vlan trunk allowed for the VLANs carried on the trunk. Option A and option B are incorrect because lacp mode enable and the shown native VLAN syntax are not the correct CX syntax. Option D is less correct because VLAN 50 is the native untagged VLAN and does not need to be included with the tagged VLAN list. The correct CX equivalent is therefore LACP active, allowed VLANs 100, 200, and 300, and native VLAN 50.

The correct answer is D. CX 8400. The requirement asks for a chassis solution, 100G speeds to the aggregation layer, and a maximum size of 10U. HPE Aruba Networking describes the CX 8400 as a core and aggregation switch with line-rate 10GbE, 25GbE, 40GbE, and 100GbE connectivity in a compact 8-slot chassis. The installation guide also identifies the CX 8400 as an eight-slot chassis platform for core and aggregation switching. This satisfies both the 100G requirement and the physical-size requirement because 8U is below the 10U maximum. The CX 10000, CX 9300, and CX 8360 are fixed-form-factor platforms rather than chassis solutions, so they do not match the customer’s chassis requirement. Therefore, the best initial proposal from the listed options is the HPE Aruba Networking CX 8400.

The correct answer is B. The SNMP service on the Conductor switch will respond to all SNMP queries for the stack. A CX 6200F VSF stack operates as a single logical switch. HPE Aruba Networking VSF documentation explains that one switch in the stack is the Conductor, and the Conductor runs the control-plane software and manages the ASICs of all stack members. The Standby member maintains a synchronized copy of the Conductor’s configuration database and can assume the Conductor role after a failure. HPE Aruba Networking documentation also states that configuration changes are applied on the Conductor switch and then synchronized to the Standby. Since the VSF stack is managed as one logical system, SNMP monitoring is performed against the stack through the active Conductor role, not by independently polling each member as a separate switch. Option A is incorrect because SNMP is not separately enabled per VSF member. Option C is incorrect because SNMP is not enabled by default on each OOBM port for member-specific queries. Option D is incorrect because both Conductor and Standby do not independently answer as separate stacked SNMP endpoints.

The correct answers are C and D. TCP uses sequence numbers and requires an established connection. HPE Aruba Networking documentation references TCP sequence-number enforcement as a firewall/security function, which confirms that TCP traffic uses sequence numbers that can be tracked and validated. HPE Aruba documentation also describes TCP traffic with an “established” option for controlling TCP connection traffic in access control entries, which indicates that TCP is connection-oriented and maintains connection state. Option A is incorrect because TCP does support retransmission; HPE Aruba EdgeConnect documentation discusses features that avoid the need for TCP retransmission, which only makes sense because retransmission is a normal TCP behavior. Option B is incorrect because connectionless behavior describes UDP, not TCP. Option E is also incorrect because latency-sensitive traffic, such as real-time voice or video, commonly favors UDP because retransmission and connection-state handling can add delay. TCP is better suited for applications that need reliable, ordered delivery, such as web, file-transfer, or management traffic, rather than real-time latency-sensitive flows.

The correct answer is B. Switch port. The Physical Layer of the OSI model is concerned with the physical transmission of signals across network media, including electrical or optical signaling, cabling, connectors, transceivers, and physical interfaces. HPE Aruba Networking hardware and transceiver documentation describes switch ports, transceiver slots, copper cabling, fiber-optic cabling, and link LEDs as physical connection components. A switch port is therefore the only option listed that belongs directly to the Physical Layer. Option A, URL, is associated with application-level access to web resources and is not a Physical Layer item. Option C, IP address, belongs to Layer 3 because it is used for logical addressing and routing. Option D, TCP port, belongs to Layer 4 because TCP ports identify transport-layer application sessions. Although a switch port may participate in Layer 2 switching after a link is established, the physical connector/interface itself is part of the Layer 1 network infrastructure. This makes “switch port” the correct answer from the listed options.
