HP Aruba Certified Mobility Expert Written - HPE6-A79 Exam Questions [2026]

QUESTION NO: 1
A network administrator has racked up a 7210 Mobility Controller (MC) that will be terminating 200+ Aps on a medium-size branch office. Next, the technician cabled the appliance with 4SPF+ Direct Attached Cables (DACs) distributed between two-member switching stack and powered it up.
What must the administrator do next in the MCs to assure maximum wired bandwidth utilization?

A. Disable spanning tree and allocate unique VLANs to each port. B. Configure the same MSTP region that the switches have. C. Map the four physical ports to port channel 0. D. Manually set 10Gbps speeds on all ports. E. Make all ports trunk interfaces and permit data VLANs.

Correct Answer: D

QUESTION NO: 2
A company plans to build a resort that includes a hotel with 1610 rooms, a casino, and a convention center. The company is interested in a mobility solution that provides scalability and a service-based approach, where they can rent the WLAN infrastructure at the convention center to any customer (tenant) that hosts events at the resort.
The solution should provide:
* Seamless roaming when users move from the hotel to the casino or the convention center
* Simultaneous propagation of the resort and customer-owned SSIDs at the convention center
* Null management access upon resort network infrastructure to the customers (tenants)
* Configuration and monitor rights of rented SSIDs to the customers (tenants) Which deployment meets the requirements?

A. Deploy lAPs with zone based SSIDs and manage them with different central accounts. B. Deploy an MM-MC infrastructure with multizone AP's, with one zone for tenant SSIDs. C. Deploy an MM-MC infrastructure, and create different hierarchy groups for MCs and APs D. Deploy lAPs along with AirWave. and deploy role-based management access control. E. Deploy lAPs. and manage them with different central accounts.

Correct Answer: E

QUESTION NO: 3
Refer to the exhibits.

A network administrator deploys User Based Tunneling (UBT) in a corporate network to unify the security policies enforcement. When users authenticate with 802.1X, ClearPass shows Accept results, and sends the Aruba-User-Role attribute as expected. However, the AOS-CX based switch does not seem to build the tunnel to the Mobility Controller (MC) for this user.
Why does the switch fail to run UBT for the user?

A. The switch is not configured with the gateway-role. B. The switch is not configured with the port-access role. C. The switch has not fully associated to the MC. D. ClearPass is sending the wrong VSA type. E. ClearPass is sending the wrong Vendor ID.

Correct Answer: E

QUESTION NO: 4
Refer to the exhibits.

A user reports slow response time to a network administrator and suggests that there might be a problem with the WLAN. The user's phone supports 802.11ac in the 5 GHz band. The network administrator finds the user in the Mobility Master (MM) and reviews the output shown in the exhibit.
What can the network administrator conclude after analyzing the data?

A. The low SNR forces the client to back off to low MCs. therefore speed is low and retransmits are high. B. High Successful frame count and high Max Speed is an indication of a healthy client. Connection will improve at anytime. C. Since SNR is good, then the high retransmit rate must be due a hidden node scenario or high interference. D. Client health is poor, but SNR is fair. TX power must be increased in both the client and the AP.

Correct Answer: B

QUESTION NO: 5
Refer to the exhibits.

A user reports slow connectivity to a network administrator when connecting to AP-Garden and suggests that there might be a problem with the WLAN. The user's device supports 802.11n in the 2.4 GHz band. The network administrator finds the user in the Mobility Master (MM) and reviews the output shown in the exhibit.
What can the network administrator conclude after analyzing the data?

A. 2.4Ghz band is currently congested, therefore a NIC upgrade to 802.11ac or higher is recommended so the user can move to 5Ghz. B. Channel usage is high and though this device has high speed the overall client rate is low on AP-Garden. there could be a few clients monopolizing the airtime on both bands at low speeds. C. 365s are low cost outdoor APs recommended for coverage design only. AP-Garden currently has more clients than recommended and is getting congested. D. User's SNR value over time is lower than recommended, therefore he should either get closer to the Access Point or increase the transmit power.

Correct Answer: C

QUESTION NO: 6
Refer to the exhibit.

A network administrator has a Mobility Master (MM) Mobility Controller (MC) architecture along with the MC in the DMZ for terminating RAPs. The network firewall has been provisioned to allow access to the MC in the DMZ for both UDP 500 and 4500. Then he proceeds to provision an AP as shown in the exhibit.
Which additional configuration steps must the administrator to assure RAPs successfully contact the MC? (Choose two.)

A. Create an IP local pool and PSK at the /mm/mynode level. B. Add the RAP1 entry in the CPsec whitelist at the MM level. C. Create the RAP1 account in the InternalDB of the MC. D. Create an IP local pool and PSK at the device node level. E. Create the RAP1 account in the InternalDB of the MM.

Correct Answer: A,B
