- Question 1Advanced
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?
Show answer & 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.

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?
Show answer & 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.

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?
Show answer & 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.

Implement RF design and network deployment features · RF planning, WLAN and AP deployment
When planning an RF deployment in a highly dense warehouse environment using HPE Aruba Networking AOS-10 APs, which TWO of the following configurations are considered best practices to minimize co-channel interference and optimize airtime? (Select TWO)
Show answer & explanation
Correct answers: D, E
Disabling lower basic rates is a standard best practice in high-density deployments. It forces management frames (like Beacons) to be transmitted at higher speeds, conserving valuable airtime, and encourages sticky clients to roam more efficiently.
In high-density environments like warehouses, using narrower channel widths (20 MHz or 40 MHz) on 5 GHz increases the number of available non-overlapping channels. This significantly reduces Co-Channel Interference (CCI) and optimizes overall network capacity.
- Question 5Beginner
Implement RF design and network deployment features · RF planning, WLAN and AP deployment
In an AOS-10 environment, an Access Point can be configured to broadcast a WLAN while simultaneously performing full-time security scanning and intrusion detection. If an administrator wants an AP to ONLY monitor the RF environment without serving any client traffic, which AP operating mode should be selected?
Show answer & explanation
Correct answer: D
Air Monitor (AM) mode dedicates the AP's radios entirely to RF monitoring, rogue AP detection, and intrusion detection (WIDS/WIPS). An AP in AM mode will not broadcast SSIDs or serve wireless clients.
- Question 6Intermediate
Configure the uplink and manage the migration · Uplink setup and migration workflow
A hospital is preparing to migrate its existing AOS-8 controller-based network to an AOS-10 cloud-managed architecture. The IT team is reviewing the firmware upgrade prerequisites. How is the firmware upgrade process managed during the migration from AOS-8 to AOS-10?
Show answer & explanation
Correct answer: A
During an AOS-8 to AOS-10 migration, HPE Aruba Networking Central handles the firmware orchestration. Administrators set a firmware compliance policy at the Group level in Central. When devices are provisioned into that group, Central automatically upgrades them to the specified AOS-10 firmware version.
