HPE6-A91 Sample Questions

  1. Question 1

    Intermediate

    Recall the fundamentals concepts of AOS-10 · AOS-10 architecture and operation

    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?

    Answer and explanation

    Correct answer: A

    In AOS-10, the architecture is controllerless from a control plane perspective. HPE Aruba Networking Central handles the management and orchestration. Access points communicate directly with Central for configuration and control plane functions (like roaming coordination). Data can be bridged locally by the AP or tunneled to a Gateway cluster, entirely eliminating the legacy AOS-8 requirement for local Mobility Controllers.

  2. Question 2

    Beginner

    Recall the fundamentals concepts of AOS-10 · AOS-10 device roles and management model

    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.

    Answer and explanation

    Correct answer: B

    False. In AOS-10, Gateways do not manage Access Points or push configurations to them. Both APs and Gateways are managed directly by HPE Aruba Networking Central. Gateways serve primarily as data plane aggregation points, VPN concentrators, and policy enforcement points.

  3. Question 3

    IntermediateMultiple answers

    Recall the fundamentals concepts of AOS-10 · AOS-10 device roles and management model

    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)

    Answer and explanation

    Correct answers: B, C, D

    A Branch Gateway role is supported in AOS-10 to provide WAN routing, firewalling, and SD-WAN capabilities at branch locations.

    A WLAN Gateway is a valid role in AOS-10, responsible for terminating User-Based Tunneling (UBT) and AP tunnels in a campus environment without SD-WAN functions.

    In AOS-10, a Gateway can operate as a VPNC to terminate SD-WAN tunnels from Branch Gateways or Microbranch APs. It can also act as a Branch Gateway (BG) or a WLAN Gateway (WG) to aggregate AP tunnels.

  4. Question 4

    Advanced

    Recall the fundamentals concepts of AOS-10 · AOS-10 architecture and operation

    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?

    Answer and explanation

    Correct answer: B

    In AOS-10, the AirMatch service is entirely cloud-native and hosted within HPE Aruba Networking Central. It collects telemetry from all managed APs, utilizes cloud computing power to calculate optimized channel, channel width, and transmit power plans, and deploys these updates to the network. This provides superior RF management compared to on-premises solutions without requiring a local Mobility Master.

  5. Question 5

    Intermediate

    Implement RF design and network deployment features · RF planning, WLAN and AP deployment

    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?

    Answer and explanation

    Correct answer: D

    AirMatch controls channel and power assignments in AOS-10. By adjusting the AirMatch radio profile for the specific AP group (auditorium), the engineer can set a lower maximum Equivalent Isotropically Radiated Power (EIRP) limit. This prevents AirMatch from assigning excessively high transmit power on 2.4 GHz, thereby reducing co-channel interference while maintaining dynamic optimization.

  6. Question 6

    Advanced

    Implement RF design and network deployment features · RF planning, WLAN and AP deployment

    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?

    Answer and explanation

    Correct answer: A

    The Wi-Fi 6E (6 GHz) standard mandates the use of highly secure protocols. Open networks and WPA2 are not permitted on the 6 GHz band. Administrators must use WPA3 (Personal/Enterprise) or Enhanced Open (OWE). Additionally, 6 GHz clients often use in-band discovery mechanisms like Reduced Neighbor Report (RNR) from 2.4/5 GHz bands to find 6 GHz networks.
