Free HP HPE6-A86 Practice Exam with Questions & Answers | Set: 2

The correct matches are 802.3af for 15.4W, 802.3at for 30W, 802.3bt Type 3 for 60W, and 802.3bt Type 4 for 90W. HPE Aruba Networking AOS-CX PoE documentation explains that PoE powered devices are divided into different types and classes according to their power requirements. It identifies Type 1 as supplying a maximum of 15.4W from the power sourcing equipment, which corresponds to IEEE 802.3af. Type 2 supplies a maximum of 30W, which corresponds to IEEE 802.3at. Type 3 supplies a maximum of 60W and Type 4 supplies a maximum of 90W, both under IEEE 802.3bt. These values are important when selecting switch PoE capability for devices such as access points, cameras, sensors, phones, and other powered devices. The switch must have both the per-port PoE capability and enough total PoE power budget to support the connected devices.

The correct answer is D. If the ZTP operation detects that the switch configuration is different from the factory-default configuration, the ZTP operation ends. HPE Aruba Networking AOS-CX documentation explains that the ZTP process starts when the switch boots with the factory-default configuration. During the ZTP process, if the switch detects that its configuration is different from the factory-default configuration, the ZTP operation ends and the switch must be configured at the installation site. This directly addresses the customer’s concern: ZTP is intended for new or factory-default switches, and it should not overwrite or change switches that have already been manually configured or deployed. Option A is incorrect because the end condition is not based on a TFTP server detecting a serial-number configuration file. Option B is incorrect because being added to Central is not the stated stopping condition. Option C describes force provisioning, which can intentionally start provisioning behavior, but it does not address the concern about protecting already configured switches.

The correct answer is D. SNMPv3. HPE Aruba Networking AOS-CX hardening documentation recommends using SNMPv3 instead of older SNMP versions because older SNMP versions are unauthenticated and unencrypted, with the community string transmitted in plaintext. The same guide states that SNMPv3 supports different users, authentication, and strong encryption. This makes SNMPv3 the secure protocol among the options. HTTP is not the best answer because standard HTTP does not encrypt management or web traffic; HTTPS would be the secure alternative. TFTP is not secure because it does not provide encryption or strong authentication for file transfers. Telnet is also not secure because it sends session traffic, including login information, in clear text; SSH is the secure alternative for CLI management. Therefore, from the listed protocols, only SNMPv3 provides security mechanisms appropriate for secure network management, including authenticated and encrypted communication.

The correct answer is D. CX 6300M in VSF. The requirement includes stacked switches, PoE+ ports, near-zero downtime, continuous packet forwarding, and highly available hardware. HPE Aruba Networking CX 6300M switches support PoE models and are part of the CX 6300 stackable switch family. HPE’s CX 6300 QuickSpecs describe high availability by design using VSF in-service software upgrades, with no downtime or restart when upgrading within the same major release, provided there is at least a two-member VSF stack. The CX 6300 family also supports modular and fixed models in a single stack and includes PoE-capable models. Option A is incorrect because the CX 8100 uses VSX rather than VSF stacking and is not the appropriate PoE+ access stack answer. Option B is less correct because the CX 6200F is stackable with VSF but does not provide the same high-availability feature set as CX 6300M. Option C is incorrect because the CX 8320 is a VSX-capable data center/core platform, not the best PoE+ stacked access solution.

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 D. UDP 161. SNMP uses different UDP ports depending on the monitoring function. When a Network Monitoring System collects or polls monitoring data from a CX switch, it communicates with the SNMP agent on the switch. HPE Aruba Networking AOS-CX SNMP documentation shows the SNMP agent port as UDP 161. This is the port used for SNMP polling and monitoring responses. This differs from SNMP traps or alerts, which are sent by the switch to a monitoring system on UDP 162. The question specifically asks about the Network Monitoring System collecting monitoring data from CX switches, so the required firewall allowance is UDP 161 from the monitoring system to the switch. Option A is incorrect because TCP 162 is not the standard SNMP polling port. Option B and option C are incorrect because UDP 1157 and TCP 1156 are not the SNMP polling ports used for this purpose.

The correct answers are A and F. Valid RADIUS authentication responses include Access-Accept and Access-Reject. HPE Aruba Networking documentation explains that a RADIUS server responds to an authentication request with an Access-Accept response when authentication succeeds, or an Access-Reject response when the user is not authorized. In the answer choices, these are represented as ACCEPT and REJECT. The other options are not valid RADIUS response names in this context. “ALLOW” and “PERMIT” may describe an access-control result in plain language, but they are not the RADIUS authentication response messages used by the protocol. “DENY” and “BLOCK” are also not the listed RADIUS response types in HPE Aruba Networking documentation. In an HPE Aruba Networking environment, RADIUS is commonly used for authentication, authorization, and accounting workflows, including administrative login and network access authentication. The important exam distinction is that the RADIUS server returns Access-Accept for successful authentication and Access-Reject for failed or unauthorized authentication.

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. 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.
