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 NI
E . The network is low because of low SN
F . TX power must be increased in both the client and the A

Answer: A

An organization owns a fully functional multi-controller Aruba network with a Virtual Mobility Master (VMM) in VLAN 20. They have asked a network consultant to deploy a redundant MM on a different server. The solution must offer the lowest convergence time and require no human interaction in case of failure.

The servers host other virtual machines and are connected to different switches that implement ACLs to protect them. The organization grants the network consultant access to the servers only, and appoints a network administrator to assist with the deployment.

What must the network administrator do so the network consultant can successfully deploy the solution? (Select three.)
A . Reserve one IP address for the second MM and another IP address for its gateway
B . Configure an ACL entry that permits IP protocol 50, UDP port 500, and multicast IP 224.0.0.18.
C . Allocate VLAN 20 to the second server, and extend it throughout the switches.
D . Reserve one IP address for the second MM and another for the VI
F . Configure an ACL entry that permits UDP 500, UDP 4500, and multicast IP 224.0.0.1.
G . Allocate another VLAN to the second server, and permit routing between them.

Answer: C

Company 1 and Company 2 are medium-sized companies that collaborate in a joint venture. Each company owns a building, and each has their own ArubaOS 8 Mobility Master (MM)-Mobility Controller (MC) deployment. The buildings are located in front of one another. For the initial stage of the project, the companies want to interconnect their networks with fiber, and broadcast each other’s SSIDs.

These are the requirements:

Do not unify the company’s network management responsibilities.

Allow each company to take care of their own SSID setups when broadcasted in the other building.

Terminate Company 1 user traffic on Company 1 MCs when they connect to Company 2 APs.

Terminate Company 2 user traffic on Company 2 MCs when they connect to Company 1 APs.

What is needed to meet the solution requirements?
A . Multizone APs
B . Inter MC S2S Ipsec tunnels
C . Multi MC Clusters
D . Inter MC GRE tunnels

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

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 network administrator adds a Mobility Controller (MC) in the /mm level and notices that the device does not show up in the managed networks hierarchy. The network administrator accesses the CLI, executes the show switches command, and obtains the output shown in the exhibit.

What is the reason that the MC does not appear as a managed device in the hierarchy?
A . The network administrator added the device using the wrong Pre=shared Key (PSK).
B . The digital certificate of the MC is not trusted by the M
D . The IP address of the MC does not match the one that was defined in the M
F . The network administrator has not moved the device into a group yet.

Answer: B

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.
