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.

A customer with a multi-controller network upgrades the ArubaOS from 6.4 to 8. The customer's clients must be able to move between different locations of the campus without disconnecting their applications, when roaming or if there are Mobility Controller (MC) failures. The customer also wants to have full control of the users, and be able to change their session properties from a RADIUS server.

Which steps must the network consultant include in the implementation plan to meet these requirements?

A. 1. Create a controller cluster profile that contains the management and VRRP IP addresses of each member.

2.

Apply the profile to all MCs in the cluster.

3.

Confirm that the cluster is L2 connected.

B. 1. Configure a VRRP instance for all MCs

2.

Create a controller cluster profile that contains the management IP and VIP addresses of each MC.

3.

Apply the profile to all MCs in the cluster.

4.

Confirm that the cluster is L2 connected.

C. 1. Configure a VRRP instance for each MC.

2.

Create a controller cluster profile that contains the management IP of each member.

3.

Apply the profile to all MCs in the cluster.

4.

Confirm that the cluster is L3 connected.

D. 1. Create a controller cluster profile that contains the management and VRRP IP addresses of each member.

2.

Apply the profile to the cluster leader.

3.

Confirm that the cluster is L2 connected.

A company has headquarters based in the US and rents internation office space in Mexico City so that 10 employees can work remotely. The company must implement a remote access technology so branch office employees can access all servers at the headquareters.

The office has both wired and wireless internet connectivity, with no restrictions on what device connects to the network. However, ports UDP 4500, 5060, and 5061 are blocked by the primeter firewall.

Which remote access technology is required to allow employees to access the servers at the headquarters?

A. BOC with CAPs

B. IAP VPN

C. RAP

D. VIA

A software development company has 700 employees who work from home. The company also has small offices located in different cities throughout the world. During working hours, they use RAPs to connect to a datacenter to upload software code as well as interact with databases.

In the past two months, brief failures have occurred in the 7240XM Mobility Controller (MC) that runs ArubaOS 8.3 and terminates the RAPs. These RAPs disconnect, affecting the users connected to the RAPs. This also causes problems with code uploads and database synchronizations. Therefore, the company decides to add a second 7240XM controller for redundancy.

How should the network administrator deploy both controllers in order to provide redundancy while preventing failover events from disconnecting users?

A. Connect both controllers with common VLANs, and create an L2-connected cluster using public addresses in the internet VLAN.

B. Connect both controllers with common VLANs, and create an HA fast failover group with public addresses in the internet VLAN.

C. Connect both controllers with different VLANs, and create an L2-connected cluster using private addresses in the internet VLAN.

D. Connect both controllers with common VLANs, and configure LMS/BLMS values equal to public addresses in the internet VLAN.

A network administrator is in charge of a wired and wireless Aruba network where access control is needed for both connection methods. For the wired solution, the network administrator wants the users authentication to be performed at the switches, while tunneling their traffic to MC1 whenever possible for firewall policy enforcement. The network administrator configures and tests ClearPass as the RADIUS server in the switches.

Which switch configuration scripts should the network administrator use next to achieve this goal?

A. tunneled-node-server controller-ip 10.19.10.100 backup-controller-ip 10.20.10.100 mode role-based aaa authentication port-access eap-radius aaa port-access authenticator 1-22 aaa port-access authenticator active

B. tunneled-node-server controller-ip 10.20.10.100 backup-controller-ip 10.19.10.100 mode port-based aaa authentication port-access eap-radius aaa port-access authenticator 1-22 aaa port-access authenticator active

C. tunneled-node-server controller-ip 10.20.10.100 backup-controller-ip 10.19.10.100 aaa authentication port-access eap-radius aaa port-access authenticator 1-22 aaa port-access authenticator active

D. tunneled-node-server controller-ip 10.19.10.100 backup-controller-ip 10.20.10.100 aaa authentication port-access eap-radius aaa port-access authenticator 1-22 aaa port-access authenticator active

Based on the output shown in the exhibit, which channel offers the highest quality?

A. Channel 1

B. Channel 6

C. Channel 11

D. Channel 14

Refer to the exhibits. Exhibit 1

Exhibit 2

A network administrator deploys role-based tunneled node in a corporate network to unify the security policies enforcement. When users authenticate with 802.1X, ClearPass shows Accept results, and sends the HPE-User-Role attribute as expected. However, the switch always applies the denyall role.

Why does the switch fail to allocate the tunnel-employee role?

A. Denyall is a secondary role contained within tunnel-employee.

B. The switch is not configured with primary tunneled-node user role.

C. The switch is not configured with secondary tunneled-node user role.

D. RADIUS Access Accept messages time out in the switch.

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.

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 deploys APs with radios in Air Monitor mode and detects several APs and SSIDs that belong to stores next door. The Mobility Master (MM) classifies the APs and SSIDs as potential rogues. The network administrator wants to prevent the Air Monitor from applying countermeasures against these APs.

How can the network administrator accomplish this?

A. Select the BSSID and click reclassify, then select neighbor.

B. Run the Define WIP Policy task, and define the BSSIDs of the neighboring APs as interfering.

C. Select the BSSID and click reclassify, then select interfering.

D. Run the Define WIP Policy task, and define the BSSIDs of the neighboring APs as Authorized.
