Free Practice Questions for HP HPE6-A86 Exam

A new firewall rule has been added = Cause

My email is not working = Symptom

My device says “No Internet” = Symptom

One of the DNS servers is offline = Cause

The switch firmware was upgraded = Cause

Websites are not loading = Symptom

The correct classification separates observed user impact from likely reasons for that impact. A symptom is what users or administrators observe, such as “email is not working,” “No Internet,” or “websites are not loading.” These describe the effect of the problem but do not identify why it is happening. A cause is a condition, change, or failure that could explain the symptom. A newly added firewall rule could block traffic, an offline DNS server could prevent name resolution, and a firmware upgrade could introduce a configuration, compatibility, or service-change issue. HPE Aruba Networking troubleshooting documentation commonly separates symptoms from causes and corrective actions; for example, AOS-CX troubleshooting sections describe a visible symptom, then identify the cause and action needed to resolve it. This method helps avoid guessing and keeps troubleshooting structured: first collect symptoms, then identify recent changes and infrastructure failures that could be possible causes. In this question, the user-facing service failures are symptoms, while the firewall, DNS, and firmware items are possible causes.

The correct matches are based on the high-availability technologies supported by each CX switch family in the answer list. HPE Aruba Networking AOS-CX VSF documentation states that VSF supports up to 8-member stacks for CX 6200F devices and up to 10-member stacks for CX 6300 devices. That makes CX 6200 match “VSF - 8 members” and CX 6300 match “VSF - 10 members.” HPE Aruba Networking documentation for VSX support lists the CX 8100 as a VSX-supported switch series, so CX 8100 matches “VSX.” The CX 6100 and CX 4100i do not match the listed VSF 8-member, VSF 10-member, or VSX choices. Although AOS-CX VSF documentation lists other VSF limits for some platforms, the choices provided only include VSF-8, VSF-10, VSX, and None; therefore, CX 6100 and CX 4100i map to “None” in this drag-and-drop question.

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 D. VSF stacking is supported within the same switch family members. HPE Aruba Networking AOS-CX VSF documentation states that a VSF stack supports combinations of models only within a supported switch family. For example, supported 6200 family models can stack with other supported 6200 family models, and supported 6300 family models can stack with other supported 6300 family models. The documentation also states that stacking is not supported across switch families. This means a VSF stack cannot mix unrelated platforms, such as chassis and fixed switches, or combine older AOS-S/Provision switches with AOS-CX switches in the same VSF stack. Option A is incorrect because VSF does not use proprietary backplane cabling; it uses supported Ethernet links, and the supported speeds depend on the switch family. Option B is incorrect because chassis and fixed platforms are not mixed in one VSF stack. Option C is incorrect because existing Provision/AOS-S switches cannot simply add CX switches as members in the same VSF stack.

The correct answer is D. As a response to the broadcast DHCP query. DHCP clients initially do not have an IP address, so they commonly use broadcast DHCP discovery/request traffic to locate a DHCP server on the local network. HPE Aruba Networking documentation for DHCP relay explains that when a DHCP client broadcasts a request, the DHCP relay agent on the switch receives the packets and forwards them to the DHCP server as unicast requests. In this scenario, the access points are in VLAN 50, and VLAN 50 also contains DHCP servers. Because the DHCP server is on the same local management VLAN as the APs, the APs can obtain addresses through the normal DHCP broadcast process within that VLAN. Anycast and multicast are not used for the basic DHCP address request in this scenario. A unicast DHCP relay message can occur between a relay agent and a DHCP server when the server is on another subnet, but the client-side DHCP discovery begins as broadcast traffic.

The correct answer is B. The switch control plane is shared. HPE Aruba Networking documentation explains that Virtual Switching Framework, or VSF, stacks multiple individual switches into a single logical device using standard Ethernet links. Once the VSF stack is formed, the interconnected switches operate as one virtual switch with a single control plane. HPE Aruba documentation also describes VSF as providing a single point of management access with a shared control plane across all stack members. Option A is incorrect because member IDs are part of the VSF configuration and may be assigned or changed during stack setup. Option C is incorrect because VSF is not universally limited to two members; supported stack size depends on the switch family and software support. Option D is incorrect because an independent management plane describes VSX more than VSF. HPE’s VSF-versus-VSX comparison identifies VSF as having a single management plane, while VSX has dual management planes.

The correct answer is D. Role-based Access Control. The configuration creates a user-defined local user group named external-auditors and then permits only specific CLI commands for that group. HPE Aruba Networking AOS-CX hardening documentation explains that user-defined local groups are used for local authorization and that local authorization uses role-based access control, or RBAC, to provide role-based privilege levels and optional command execution rules. The CLI command documentation also states that permit or deny cli command rules define which CLI commands can be executed by members of a user-defined group, with an implicit deny rule at the end. This matches RBAC because access is granted according to the user’s assigned role or group. Option A is incorrect because authentication verifies identity, such as username and password. Option B is incorrect because accounting records user activity. Option C is broader security architecture terminology, but the specific configuration shown is command authorization through RBAC.

The correct answer is B. Light. Multi-mode cable refers to multi-mode fiber-optic cabling. In fiber-optic transmission, data is carried using light through the fiber core. HPE Aruba Networking’s transceiver documentation explains that multimode fibers have thicker fiber cores and can transport light in multiple modes. The same HPE Aruba Networking transceiver guidance discusses optical transceivers transmitting light pulses and managing light loss across fiber-optic cabling. Therefore, in the context of multi-mode fiber, the signal being modulated to represent data is light. Option A is incorrect because radio is used in wireless transmission, not fiber-optic cabling. Option C is incorrect because voltage is associated with electrical copper cabling, such as twisted-pair Ethernet, rather than optical fiber. Option D is incorrect because pressure is not used as the signaling method for standard Ethernet fiber links. This question is focused on Layer 1 media behavior, and multi-mode fiber is a Physical Layer medium that transports optical signals between network transceivers.

The correct answer is D. Dynamic Segmentation. HPE Aruba Networking describes Dynamic Segmentation as an identity-based access control solution for Zero Trust and SASE security from edge to cloud. Dynamic Segmentation applies policy based on the identity and role of users and devices, rather than relying only on physical network location, VLAN placement, or static port configuration. This is important in Zero Trust because no user, device, or network segment should be automatically trusted. Access should be continuously controlled and limited to only the resources required. HPE Aruba Networking documentation also explains that Dynamic Segmentation establishes least-privilege access by segmenting traffic based on identity and associating consistent role-based access policies across wired, wireless, and WAN networks. The other options are not the best answer. Virtual Switching Framework and Virtual Switching Extension are resiliency or virtualization technologies, not the core Zero Trust/SASE policy feature. Network Analytics Engine is useful for monitoring, automation, and troubleshooting, but Dynamic Segmentation is the security framework feature directly tied to Zero Trust and SASE.
