HP Updated HPE6-A86 Exam Questions and Answers by libby

The correct answer is D. QoS. Poor call quality during network congestion is commonly caused by delay, jitter, or packet loss affecting real-time voice and video traffic. HPE Aruba Networking AOS-CX Quality of Service documentation explains that QoS allows administrators to customize how different traffic types are serviced based on their characteristics and importance. QoS helps keep important traffic moving at an acceptable speed regardless of current bandwidth usage. HPE Aruba documentation also states that VoIP traffic is delay and jitter sensitive and should receive priority service for optimum transmission. Microsoft Teams voice and video traffic is latency-sensitive, so configuring QoS is the correct approach to prioritize this traffic when the network is busy. Option A, CoS, is a specific Layer 2 priority marking method that can be part of a QoS design, but the broader feature to configure is QoS. Option B, ZIP, is not relevant. Option C, IGMP, is used for multicast group management and does not solve general Teams call-quality issues.

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 D. To configure a physical interface as a Layer 3 routed port on an HPE Aruba Networking CX 6300 switch, the interface must be placed in routing mode and assigned an IP address directly. This creates a routed interface rather than a bridged Layer 2 port. HPE Aruba Networking AOS-CX examples show routed physical interfaces configured with routing, followed by an ip address, and then no shutdown. The same examples contrast this with Layer 2 ports, which use no routing and VLAN commands such as vlan access or vlan trunk. Option A is incorrect because no routing makes the interface a Layer 2 interface, so assigning an IP address directly is not the correct routed-port configuration. Options B and C are incorrect because vlan access 1 configures the port as a bridged access port. The requirement specifically says the switch should be configured without a bridged port, so the correct CX configuration is a routed physical interface using routing with the IP address configured directly on the port.

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.
