Free Practice Questions for HP HPE6-A86 Exam

The correct answer is B. Suitable for basic Layer 3 networks. HPE Aruba Networking AOS-CX IP Routing documentation describes static routing as a method that can be used when the network topology is simple enough. Static routes are manually configured routes that tell the switch how to reach specific destination networks or where to send default traffic. This makes static routing useful for smaller, stable, or basic Layer 3 environments where the number of routes is limited and the topology does not change frequently. Option A is incorrect because static routing is normally predictable; the administrator explicitly defines the path. Option C is incorrect because static routing does not scale well to large or complex networks, since every required route must be manually maintained. Option D is incorrect because static routing does not automatically adapt to network failures across the whole network like a dynamic routing protocol can. Therefore, static routing is best described as suitable for basic Layer 3 networks.

The correct answer is C. Application Layer. HTTP, or Hypertext Transfer Protocol, is identified in HPE Aruba Networking documentation as an application protocol used to transfer data over the web. The same HPE Aruba Central documentation explains that HTTP defines how messages are formatted and transmitted and how web servers and browsers respond to commands. This places HTTP at the application layer because it directly supports user-facing web communication rather than packet forwarding, addressing, framing, or physical transmission. HPE Aruba documentation also describes Deep Packet Inspection and AppRF as Layer 7 or Application Layer features that classify applications and web traffic, further supporting that HTTP is treated as application-layer traffic. Option A is incorrect because the Session Layer manages sessions between systems, but HTTP itself is not categorized there in this context. Option B is incorrect because the Network Layer handles IP addressing and routing. Option D is incorrect because the Data Link Layer handles local network framing, MAC addressing, and switching behavior.

The correct answers are A and E. HPE Aruba Networking AOS-CX switches support RADIUS and TACACS+ for controlling administrative access. HPE Aruba Networking security documentation describes remote AAA authentication and authorization using RADIUS or TACACS+ servers. These protocols allow administrative logins and command authorization to be managed centrally instead of relying only on local switch users. RADIUS is commonly used for authentication, authorization, and accounting services, while TACACS+ is especially useful for administrative access control because it can provide command authorization and accounting. LDAP, Diameter, and SAML are not the correct answers for the AOS-CX administrative access control protocols listed in this question. LDAP is a directory protocol, Diameter is an AAA protocol used in other service-provider contexts, and SAML is commonly used for web-based single sign-on, but they are not the two AOS-CX switch administrative access protocols being tested here.

The correct answer is D. administrators. HPE Aruba Networking AOS-CX documentation for the 4100i, 6000, and 6100 switch series states that, in addition to user-defined local groups, there are three built-in user groups: administrators, operators, and auditors. The documentation also states that the default admin account belongs to the administrators group. This makes administrators the only valid default group among the answer choices. Option A, root, is not listed as a built-in AOS-CX user group. Option B, managers, is not one of the default AOS-CX groups. Option C, super-users, is also not listed as a built-in group. These names may appear in other systems or older platforms, but on HPE Aruba Networking CX 6100 switches, the built-in local user groups are administrators, operators, and auditors. Therefore, the correct default user group from the listed options is administrators.

The correct answer is D. Create VSF on the CX 6200 switches and a LAG between the CX 6200 and 2530 switches. HPE Aruba Networking documentation explains that VSF allows multiple individual switches to operate as a single logical device using standard Ethernet links. The CX 6200 supports VSF stacking, so two CX 6200 aggregation switches can be combined into a single logical aggregation switch. HPE Aruba Networking Layer 2 documentation also describes link aggregation as grouping individual physical interfaces into a single logical link, increasing bandwidth and providing resiliency when links fail. In this design, the 2530 access switch can use two uplink ports in a trunk/LAG toward the aggregation layer, while the CX 6200 side operates as one logical switch because of VSF. Option A is incorrect because a CX 6200 and a 2530 cannot be placed into one common VSF stack. Option B is incorrect for the same reason: the 2530 is not stacked with the CX 6200. Option C is incomplete because a LAG from one access switch to two separate aggregation switches requires the aggregation side to act as one logical switch, which is provided by VSF in option D.

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 C. Input errors have occurred. The interface output shows CRC/FCS errors with a value of 1254 under the RX column. CRC/FCS errors are receive-side frame check errors, so they indicate that the switch has received corrupted frames on this interface. HPE Aruba Networking AOS-CX show interface documentation lists interface statistics including packets, bytes, dropped frames, pause frames, errors, CRC/FCS, collisions, runts, and giants, which confirms that CRC/FCS is part of the interface error statistics. Option A is incorrect because the output says VLAN Mode: access and Access VLAN: 90; an access VLAN is untagged toward the endpoint, not an 802.1Q tagged trunk VLAN. Option B is incorrect because the MTU is shown as 1500, and the Jumbos counter is 0, so the output does not indicate jumbo-frame use. Option D is incorrect because the shown output does not state that PoE is disabled. The key troubleshooting clue is the nonzero receive CRC/FCS counter. ( arubanetworking.hpe.com )

The correct answer is C. Automates root cause analytics. HPE Aruba Networking AOS-CX documentation describes the Network Analytics Engine, or NAE, as a framework within AOS-CX switches that automates the detection of issues and automates root cause analysis. NAE agents monitor switch resources, events, configuration, protocol states, and other operational data to help identify issues faster. This helps administrators move from manual troubleshooting to analytics-driven troubleshooting directly on the switch. Option A is not the best answer because NAE is not simply a feature that automatically creates tech-support diagnostic files. Option B is incorrect because automated configuration backups are not the main purpose of NAE. Option D is incorrect because NAE does not primarily create support events in the HPE Aruba Networking Support Portal. Its purpose is local switch analytics, issue detection, and root cause analysis. Therefore, the best description is that NAE automates root cause analytics.

The correct answer is D. The VSF stack remains fully operational. The output shows the VSF topology is a ring. In a ring topology, each member has an alternate VSF path through another member. If only the VSF link between members 1 and 2 is disconnected, members 1 and 2 can still communicate through member 3: member 1 connects to member 3, and member 3 connects to member 2. This changes the physical topology from a ring to a chain, but it does not split the stack. HPE Aruba Networking VSF documentation states that a ring topology provides resiliency against link and member hardware failures because any single failure does not isolate the remaining stack members from each other, and Aruba strongly recommends ring topology where possible. Options A, B, and C are incorrect because a single link failure in this three-member ring does not isolate the conductor, standby, or member. Split detection using the management interface would become relevant only if the stack actually split into separate fragments.
