Free HP HPE6-A86 Practice Exam with Questions & Answers

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 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 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 C. auditors. HPE Aruba Networking AOS-CX documentation for the 6200, 6300, and 6400 switch series identifies three built-in user groups: administrators, operators, and auditors. These built-in groups have fixed privileges. The administrators group has full privileges, including full CLI access, firmware upgrades, configuration viewing, configuration changes, and user account management. The operators group has no switch configuration privileges and is mainly limited to basic display-only access and viewing nonsensitive configuration information. The auditors group is restricted to audit-related functions. Since the question asks which user group exists by default on a CX 6400 Series switch, “auditors” is the only listed option that matches the HPE Aruba Networking AOS-CX built-in groups. The other options—read-only, restricted, and reporting—are not listed as default built-in AOS-CX user groups for the CX 6400 platform. This makes option C the verified answer.

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. Single-mode fiber. A 35 km connection between two sites is a long-distance optical link, and single-mode fiber is the appropriate cable type for long-haul communication. HPE Aruba Networking transceiver documentation describes single-mode fiber as having a small core size and being suitable for long-haul communication because it transmits light in one mode and suffers less intermodal dispersion than multi-mode fiber. Multi-mode fiber is used for shorter-distance links inside buildings or data centers and is not the correct choice for a 35 km site-to-site connection. UTP copper cabling cannot support a 40Gbps Ethernet connection over 35 km. ZTP is Zero Touch Provisioning, not a cable type. HPE Aruba transceiver guidance also lists long-distance optical transceivers, such as 40 km single-mode fiber options, reinforcing that long-distance high-speed links require SMF rather than MMF or copper. Therefore, for a 40Gbps link between sites 35 km apart, the required cabling is single-mode fiber. ( arubanetworking.hpe.com )

The correct answer is B. CX 6200. The feature being described is the HPE Aruba Networking AOS-CX Network Analytics Engine, or NAE. HPE Aruba Networking documentation states that NAE uses Python scripts to define which switch resources to monitor and optionally what actions to take when certain conditions are true. The NAE guide specifically applies to the CX 6200, 6300, 6400, 8xxx, 9300, and 10000 switch series, and the supported maximums page lists the CX 6200 as supporting up to 10 scripts and 10 agents. This makes the CX 6200 the correct choice from the available options. The CX 6000, CX 6100, and CX 4100i are lower access platforms and are not listed in the NAE guide’s supported product set for onboard NAE scripting. Therefore, for a customer with Python skills who wants to use self-made or Aruba-provided onboard analytics scripts, the CX 6200 is the appropriate recommendation.

The correct answer is C. Lowest administrative distance. When a switch learns multiple possible routes to the same destination, it must select the preferred or best route to install and use for forwarding. HPE Aruba Networking documentation explains that administrative distance is one of the main criteria used to determine the preferred route when multiple paths exist to the same destination. The route with the lower administrative distance takes precedence. This is why connected routes, static routes, and dynamically learned routes can be preferred differently depending on their administrative distance values. Option A is incorrect because a default route is used only when no more specific route exists. Option B is incorrect because a static route is not automatically selected merely because it is static; it is preferred only if its administrative distance and route specificity make it the best candidate. Option D is incorrect because the highest administrative distance is less preferred, not more preferred.

The correct answer is B. HPE Aruba Networking Central has been manually disabled on the switch. The key line in the output is Central admin state : disabled. HPE Aruba Networking AOS-CX documentation for the show aruba-central command provides an example of a switch when Aruba Central is disabled, showing Central admin state : disabled, Central connection values as N/A, and Central support mode as disabled. This indicates that the switch’s Central administrative state is disabled, so it is not attempting to connect to HPE Aruba Networking Central. Option A is incorrect because the VRF for connection : N/A value is a result of Central being disabled, not proof that the management VRF does not exist. Option C is incorrect because this command output does not report support-contract validity. Option D is incorrect because the factory-default Central behavior is not what is being shown; the output specifically reflects Central being disabled. Therefore, the correct interpretation is that Central has been manually disabled on the switch. ( arubanetworking.hpe.com )

The correct answer is B. Member 2 becomes Conductor. In the shown VSF stack, member 1 is currently the Conductor, member 2 is the Standby, and member 3 is a regular Member. HPE Aruba Networking VSF documentation explains that the Conductor runs the control plane for the VSF stack, while the Standby keeps a synchronized copy of the Conductor’s configuration database. If the Conductor fails or reboots, the Standby takes over the Conductor role to maintain stack operation. Since the output explicitly shows member 2 as the Standby, member 2 is the member expected to become the new Conductor when member 1 reboots. Option A is incorrect because member 2 is already Standby before the reboot. Option C is incorrect because member 3 is only a normal Member and would not take over while a Standby exists. Option D is not the best answer because the immediate role transition asked by the question is the Standby becoming Conductor.
