HP Updated HPE6-A86 Exam Questions and Answers by callan

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 D. It is available as a cloud solution. HPE Aruba Networking Central is described in official Aruba documentation as a cloud-based management platform for managing AOS-CX infrastructure. It provides centralized functions for provisioning, configuring, monitoring, and troubleshooting AOS-CX switches. This means it is not limited to on-premises deployment. Option A is incorrect because AOS-CX support in Aruba Central is not limited only to templates; Central also supports monitoring, troubleshooting, and UI-based workflows depending on the software version, group type, and deployment model. Option B is also incorrect because monitoring-only mode is one supported option, but it is not the only supported mode. HPE Aruba documentation specifically notes that AOS-CX switches can be added in monitoring-only mode, but also separately documents configuration using templates and UI groups. Therefore, the broad and correct description for a customer conversation is that HPE Aruba Networking Central is available as a cloud management solution for AOS-CX switches.

The correct answer is B. Push-to-talk radio. Half-duplex communication allows transmission in both directions, but not at the same time. A push-to-talk radio is a common example because one person presses the talk button and transmits while the other side listens; then the first person stops transmitting so the other person can reply. This differs from a telephone system, which is normally full-duplex because both parties can speak and hear at the same time. FM radio broadcast is simplex, because communication normally flows in only one direction from the broadcaster to receivers. A fibre-optic pair is commonly used for full-duplex communication because separate fibers or transmit/receive paths can support simultaneous sending and receiving. In HPE Aruba Networking switch documentation, duplex is discussed as a Layer 1/Layer 2 port characteristic, with half-duplex supported for some Ethernet speeds and full-duplex used for modern switched links. Therefore, the option that best represents half-duplex behavior is push-to-talk radio.

The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options—helpdesk, servicedesk, and support—are not listed as built-in default user groups for the CX 8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.
