HPE6-A91 sample questions

Question 1

A network architect is designing a greenfield wireless deployment for a large enterprise campus. The organization has chosen HPE Aruba Networking AOS-10 to simplify management and scale seamlessly without relying on physical on-premises mobility controllers. Which of the following best describes the fundamental architectural shift in the AOS-10 control plane compared to legacy AOS-8 environments?

Accepted Answer

Management and control plane operations are centralized in HPE Aruba Networking Central, allowing APs to function autonomously for data forwarding or tunnel to a Gateway without requiring local controllers.

Answer

Access points establish an IPsec tunnel to a local virtual mobility controller for control plane traffic, while data plane traffic is bridged locally.

Answer

All control, management, and data plane intelligence is shifted entirely to the individual access points, removing the need for any centralized management platform.

Answer

AOS-10 Gateways manage the control plane for all connected APs, acting identically to an AOS-8 Mobility Master but hosted in the cloud.

Question 2

True or False: In an AOS-10 deployment, HPE Aruba Networking Gateways operate primarily as management controllers that push configurations to Access Points in a localized branch.

Accepted Answer

False

Answer

True

Question 3

A financial services organization is planning their AOS-10 topology. They intend to deploy HPE Aruba Networking Gateways in their data center to handle various networking functions. Which THREE of the following are valid roles that a Gateway can be assigned to perform in an AOS-10 environment? (Select THREE)

Accepted Answer

Virtual Private Network Concentrator (VPNC)

Accepted Answer

WLAN Gateway (WG)

Accepted Answer

Branch Gateway (BG)

Answer

Mobility Master (MM)

Answer

AirMatch Cloud Controller (ACC)

Question 4

A multinational corporation is evaluating a transition from a legacy AOS-8 Mobility Master deployment to AOS-10. The CIO is concerned about losing the localized RF intelligence and dynamic channel optimization that the on-premises Mobility Master provided.

As the lead architect, how should you explain the handling of RF optimization in AOS-10 to alleviate the CIO's concerns?

Accepted Answer

The AirMatch service runs natively within HPE Aruba Networking Central, leveraging cloud computing to analyze daily telemetry and push optimized channel and power plans to the APs.

Answer

AOS-10 utilizes legacy Adaptive Radio Management (ARM) on each individual AP to make localized decisions independently, removing the need for a central orchestrator.

Answer

RF optimization is now executed by the AOS-10 Gateway clusters running a virtual instance of AirMatch, ensuring on-premises data processing is maintained.

Answer

AOS-10 requires a third-party RF management server to be integrated via API, as native RF intelligence was deprecated in favor of a simplified AP architecture.

Question 5

A network engineer is troubleshooting poor roaming performance in a high-density auditorium. They notice that the APs are operating at maximum transmit power on the 2.4 GHz band, causing significant co-channel interference. In HPE Aruba Networking Central (AOS-10), what is the most appropriate method to resolve this specific issue globally for the auditorium?

Accepted Answer

Adjust the AirMatch radio profile for the auditorium's AP group to lower the maximum EIRP limit for the 2.4 GHz band.

Answer

Disable the 2.4 GHz radio on all APs in the auditorium using a device-specific configuration override.

Answer

Enable ClientMatch strict-mode to force all clients to 5 GHz, inherently reducing the 2.4 GHz transmit power.

Answer

Log into the Gateway cluster CLI and execute the 'rf dot11g-radio-profile reduce-power' command.

Question 6

A university is deploying Wi-Fi 6E (AOS-10 APs) in their new engineering building. The design requires maximizing capacity using the 6 GHz band. However, during initial testing, legacy clients are unable to discover the 6 GHz BSSIDs. Which configuration requirement is MANDATORY when deploying the 6 GHz band to ensure proper operation and discovery by 6 GHz capable clients?

Accepted Answer

The 6 GHz SSID must utilize WPA3 (Personal or Enterprise) or OWE; legacy security protocols like WPA2 and Open are strictly prohibited by the standard.

Answer

The WLAN must be configured with WPA2/WPA3 transition mode to allow legacy clients to view the 6 GHz beacons.

Answer

Multiple BSSID (MBSSID) must be disabled on the APs to prevent beacon collision in the 6 GHz spectrum.

Answer

The APs must be connected to an AOS-10 Gateway using an IPsec tunnel to encrypt 6 GHz management frames.
