HPE6-A48 Online Practice Questions and Answers

A bank deploys an Aruba Mobility Master (MM)-Mobility Controller (MC) solution to provide wireless access for users that run different applications on their laptops, including SIP-based IP telephony. When users only run the IP telephony software, call quality is high. However, if users also run email, web, or mission critical applications, then voice quality drops.

Which feature would help improve the quality of voice calls over the air when users run different applications?

A. DSCP for IPv4 traffic

B. WiFi Multi Media

C. Type of Service

D. High/Low Queue

A point venture between two companies results in a fully functional WLAN Aruba solution. The network administrator uses the following script to integrate the WLAN solution with two radius servers, radius1 and radius2.

While all users authenticate with [email protected] type of credentials, radius1 has user accounts without the domain name portion.

Which additional configuration is required to authenticate corp1.com users with radius1 and corp2 users with radius2?

A. aaa authentication-server radius radius1 trim-fqdn ! aaa server-group-corp auth-server radius1 match-authstring corp1.com auth-server radius1 match-authstring corp2.com

B. aaa server-group-corp auth-server radius1 match-fqdn corp1.com auth-server radius1 trim-fqdn auth-server radius2 match-fqdn corp2.com

C. aaa authentication-server tadius radius1 ! aaa server-group-corp auth-server radius1 match-string corp1.com trim-fqdn auth-server radius1 match-string corp2.com

D. aaa authentication-server radius radius1 trim-fqdn ! aaa server-group-corp auth-server radius1 match-domain corp1.com auth-server radius1 match-domain corp2.com

Refer to the exhibit.

A user reports show response time to a network administrator and suggests that there might be a problem with the WLAN. The user's laptop supports 802.11n in the 2.4 GHz band only. The network administrator finds the user on the Mobility Master (MM) and reviews the output shown in the exhibit.

What can the network administrator conclude after analyzing the data?

A. Client health is low, and retried frames are high. It is possible there is high channel utilization.

B. Client health is low, but SNR is high. It is possible data in the dashboard is not accurate and needs to be updated.

C. The speed is good. Client health seems to be related to a problem with the client NIC.

D. The network is low because of low SNR. TX power must be increased in both the client and the AP.

Refer to the exhibits. Exhibit 1

Exhibit 2 Exhibit 3

A network administrator deploys a Mobility Master (MM) pair with the VRRP VIP equal to 10.254.10.214, and attempts to associate MC1 to it. At first, the integration appears to be successful. However after a few minutes the network administrator issues the show switches command and sees that the MC1 is down, even though the device is up and running.

Every time the network administrator reboots the Mobility Controller (MC), the MC shows as being up and then it shows as being down. The network administrator gathers the information shown in the exhibits.

What should the network administrator do to resolve this problem?

A. Change the localip ipsec key to Aruba123 in the mynode device level from the MM, save, and reboot.

B. Enable disaster recovery mode in MC1 and change the masterip ipsec key to Aruba 123, save, and reboot.

C. Change the masterip ipsec key to Aruba123 in the device level from the MM, save, then reboot MC1.

D. Wipe out the configuration in MC1 and reboot, then run the full-setup configuration dialog all over again.

Refer to the exhibit.

A network administrator deploys a multizone AP in the campus network in order to provide service for 11 SSIDs. After a few hours, the network administrator realizes that the AP is only broadcasting 5 out of the 11 SSIDs. The missing SSIDs belong to MC1 at IP address 10.254.10.114, and MC4 with IP address

10.2.100.25.

Based on the exhibit, what should the network administrator do next to fix this problem?

A. Confirm that AP12 is certified by the whitelist on MC1 and MC4, and confirm MC1 and MC4 are reachable by AP12.

B. Increase the number of nodes in zones 1 and 4, and confirm MC1 and MC4 are reachable by AP12.

C. Confirm that AP12 is certified by the whitelist on MC1 and MC4, and increase the number of nodes in zones 1 and 4.

D. Reduce the number of nodes in zones 0 and 4, and disband the cluster in zone 0.

Refer to the exhibit.

A network administrator is validating client connectivity and executes the show command shown in the exhibit. Which authentication method was used by the wireless station?

A. 802.1X user authentication

B. EAP authentication

C. 802.1X machine authentication

D. MAC authentication

A network administrator wants to receive a major alarm every time a controller or an Aruba switch goes down for either a local or an upstream device failure. Which alarm definition must the network administrator create to accomplish this?

A. Option A

B. Option B

C. Option C

Refer to the exhibit.

A user's laptop only operates in the 2.4 GHz band and supports 802.11n. This user reports that the network is slow at the cafeteria that is serviced by three APs, and suggests that there might be a problem with the WLAN. The network administrator finds the user in the MM, and obrains the output shown in the exhibit.

What should the network administrator do to optimize the client connection?

A. Disable lower transmit rates in the SSID profile.

B. Change the channel being used in the radio profile.

C. Reduce Min/Max channel bandwidth in the radio profile.

D. Reduce Min/Max EIRP in the ARM profile.

Refer to the exhibit.

Help desk staff receive reports from users that there is inefficient wireless service in a location serviced by AP20, AP21, and AP22, and open a ticket. A few hours later, the users report that there is a drastic improvement in service. The staff still wants to determine the cause of the problem so the next day thay start monitoring the tasks.

They access the Mobility Master (MM), and obtain the output shown in the exhibit.

What could be the cause of the problem that the users reported?

A. AirMatch was running an initial incremental optimization.

B. An operator used AirMatch to manually freeze AP channel and power.

C. An operator manually assigned settings in the radio profile.

D. AirMatch was running a full on-demand optimization.

A network administrator assists with the migration of a WLAN from a third-party vendor to Aruba in different locations throughout the country. In order to manage the solution from a central point, the network administrator decides to deploy redundant Mobility Masters (MMs) in a datacenter that are reachable through the Internet.

Since not all locations own public IP addresses, the security team is not able to configure strict firewall policies at the datacenter without disrupting some MM to Mobility Controller (MC) communications. They are also concerned about exposing the MMs to unauthorized inbound connection attempts.

What should the network administrator do to ensure the solution is functional and secure?

A. Deploy an MC at the datacenter as a VPN concentrator.

B. Block all ports to the MMs except UDP 500 and 4500.

C. Install a PEFV license, and configure firewall policies that protect the MM.

D. Block all inbound connections, and instruct the MM to initiate the connection to the MCs.
