HPE6-A85 Exam Questions and Answers

QUESTION: 6

What happens when the signal from an AP weakens by being absorbed as it moves through an object?

APs will use bonded channels to decrease latency to clients
Signal to Noise Ratio (SNR) increases
Signal to Noise Ratio (SNR) decreases
Aruba Central dynamically moves clients to neighboring APs

Answer(s): C

Explanation:

Signal to noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels (dB). A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover.
When the signal from an AP Access Point. AP is a device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. weakens by being absorbed as it moves through an object, such as a wall or a furniture, the signal power decreases. This reduces the SNR and affects the quality of the wireless connection. The noise power may also increase due to interference from other sources, such as other APs or devices operating in the same frequency band. Therefore, the correct answer is that SNR decreases when the signal from an AP weakens by being absorbed as it moves through an object.

See Explanation section for answer.

Answer(s): A

Explanation:

Features: 1) Clustered Instant Access Points Aruba OS version: a) Aruba OS 8
Features: 2) Dynamic Radius Proxy Aruba OS version: a) Aruba OS 8
Features: 3) Scales to more than 10,000 devices Aruba OS version: b) Aruba OS 10
Features: 4) Unifies wired and wireless management Aruba OS version: a) Aruba OS 8
Features: 5) Wireless controllers Aruba OS version: a) Aruba OS 8 ArubaOS is the operating system for all Aruba Mobility Controllers (MCs) and controller-managed wireless access points (APs). ArubaOS 8 delivers unified wired and wireless access, seamless roaming, enterprise grade security, and a highly available network with the required reliability to support high density environments. Some of the features of ArubaOS 8 are:
Clustered Instant Access Points: This feature allows multiple Instant APs to form a cluster and share configuration and state information. This enables seamless roaming, load balancing, and fast failover for clients.
Dynamic Radius Proxy: This feature allows an MC to act as a proxy for RADIUS authentication requests from clients or APs. This simplifies the configuration and management of RADIUS servers and reduces the network traffic between MCs and RADIUS servers. Wireless controllers: Aruba wireless controllers are devices that centrally manage and control the wireless network. They provide functions such as AP provisioning, configuration, security, policy enforcement, and network optimization.
ArubaOS 10 is the next-generation operating system that works with Aruba Central, a cloud-based network management platform. ArubaOS 10 delivers greater scalability, security, and AI-powered optimization across large campuses, branches, and remote work environments. Some of the features of ArubaOS 10 are:
Scales to more than 10,000 devices: ArubaOS 10 can support up to 10,000 devices per cluster, which is ten times more than ArubaOS 8. This enables customers to scale their networks without compromising performance or reliability.
Unifies wired and wireless management: ArubaOS 10 provides a single platform for managing both wired and wireless devices across the network. Customers can use Aruba Central to configure, monitor, troubleshoot, and update their devices from anywhere. Both ArubaOS 8 and ArubaOS 10 share some common features, such as:
Unifies wired and wireless management: Both operating systems provide unified wired and wireless access for customers who use Aruba switches and APs. Customers can use a single interface to manage their entire network infrastructure1 .

QUESTION: 8

Which Aruba technology will allow for device-specific passphrases to securely add headless devices to the WLAN?

Wired Equivalent Privacy (WEP)
Multiple Pre-Shared Key (MPSK)
Opportunistic Wireless Encryption (OWE)
Temporal Key Integrity Protocol (TKIP)

Answer(s): B

Explanation:

Multiple Pre-Shared Key (MPSK) is a feature that allows device-specific or group-specific passphrases to securely add headless devices to the WLAN Wireless Local Area Network. WLAN is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. . MPSK enhances the WPA2 PSK Wi-Fi Protected Access 2 Pre-Shared Key. WPA2 PSK is a method of securing your network using WPA2 with the use of the optional Pre-Shared Key (PSK) authentication, which was designed for home users without an enterprise authentication server. mode by allowing different PSKs for different devices on the same SSID Service Set Identifier. SSID is a case-sensitive, 32 alphanumeric character unique identifier attached to the header of packets sent over a wireless local-area network (WLAN). The SSID acts as a password when a mobile device tries to connect to the basic service set (BSS) -- a component of the IEEE 802.11 WLAN architecture. . MPSK passwords can be generated or user-created and are managed by ClearPass Policy Manager.

QUESTION: 9

Refer to the exhibit.

In the given topology, a pair of Aruba CX 8325 switches are in a VSX stack using the active gateway What is the nature and behavior of the Virtual IP for the VSX pair if clients are connected to the access switch using VSX as the default gateway?

Virtual IP is active on the primary VSX switch
Virtual floating IP will failover in case of a failure
Virtual IP is active on both CX switches
Virtual IP uses SVI IP address synced with VSX

Answer(s): B

Explanation:

In a Virtual Switching Extension (VSX) stack, the Virtual IP (VIP) provides a single default gateway IP address for clients connected to the access switch. This VIP is a floating IP that is active on the primary VSX switch. In the event of a failure of the primary switch, the VIP will failover to the secondary switch, ensuring that client traffic can continue to be routed without disruption.

QUESTION: 10

When performing live firmware upgrades on Aruba APs. which technology partitions all the APs based on RF neighborhood data minimizing the impact on clients?

Aruba ClientMatch
Aruba Ai insights
Aruba AirMatch
Aruba ESP

Answer(s): C

Explanation:

Aruba AirMatch is a feature that optimizes RF Radio Frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation.
When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. performance and user experience by using machine learning algorithms and historical data to dynamically adjust AP power levels, channel assignments, and channel width. AirMatch performs live firmware upgrades on Aruba APs by partitioning all the APs based on RF neighborhood data and minimizing the impact on clients. AirMatch uses a rolling upgrade process that upgrades one partition at a time while ensuring that adjacent partitions are not upgraded simultaneously.
