Question1: A WLAN in an Aruba Mobility Master (MM)-based solution uses WPA2-Enterprise security. This WLAN currently authenticates users to Active Directory (AD), and users log in with their Windows domain credentials. Network administrators now want to authenticate the Windows clients as well, based on the client Computer Names.
What should the administrators do on MM to achieve this goal?

Question2: What is the minimum space between channels in the 2.4GHz range to prevent overlap?

Question3: For which use case should network administrators set up Aruba access points (APs) as multi-zone APs?

Question4: A network administrator creates the role employees and adds the rule to it:
user any any permit
The first several wireless clients assigned to the employees role are assigned IP addresses in the 10.10.10.0/24 subnet. Several other wireless clients with the employees role are then assigned IP addresses in the
10.10.20.0/24.
When the Aruba firewall matches traffic from these clients to the user any any permit rule, what does it do?

Question5: Refer to the exhibit.

The exhibit shows output from a Mobility Master (MM) dashboard. What is a valid reason for the administrator to click the akamai square under applications?

Question6: What is one reason for a network administrator to visit the Dashboard > Usage window on an Aruba Mobility Master (MM)?

Question7: A network administrator monitors an Aruba Mobility Controller with Aruba AirWave and sees the configuration status is Error. What should the administrator conclude?

Question8: Refer to the exhibit.

A network administrator needs to specify a RADIUS server for an employee WLAN on an Aruba solution.
What must the administrator enter in the Shared key field?

Question9: Which class of controller is more appropriate in a branch installation with up to 64 APs?

Question10: A company has an Aruba solution that supports an employee WLAN. How can network administrators control in which subnets users receive IP addresses?

Question11: Refer to the exhibits.
Exhibit 1

Exhibit 2

A company has an Aruba Mobility Master (MM)-based solution and needs a new WLAN for the corporate campus. A network administrator completes the creation of this WLAN, as shown in Exhibit 1. When the administrator tries to test a connection to the WLAN in various locations, the WLAN sometimes shows up in the list of WLANs on the client but sometimes does not. The administrator can see the WLAN in the list, as shown in Exhibit 2.
What is the error?

Question12: An Aruba Mobility Master (MM)-based solution has a WLAN that uses WPA2-Enterprise security. A test login on a wireless client fails.
How can a network administrator determine whether the RADIUS server rejected the credentials or another issue occurred?

Question13: What is one setting that a network administrator can configure for user roles in an Aruba solution?

Question14: A network administrator wants to implement MAC filtering for the wireless network of a local financial firm to ensure that only employees can access the wireless network. What is a potential weakness of this solution?

Question15: A company has a Mobility Master (MM)-based solution with an employee WLAN Several users report that they can connect to the WLAN, but they cannot access all of the resources that they should.
Where should the network administrator look in the MM interface to find the roles to which these users are actually assigned?

Question16: Refer to the exhibit.

The exhibit shows output from a Mobility Master (MM) dashboard. What is a valid reason for the administrator to click the akamai square under applications?

Question17: Refer to the exhibits.
Exhibit 1

Exhibit 2

A company has a Mobility Master (MM)-based solution with a guest WLAN. Users can connect to the WLAN, but they receive the error shown browser rather than see login page. Exhibit 2 shows the status for one of the guest clients.
What is one issue that could cause the errors described?

Question18: A network administrator needs to create an Aruba firewall rule that permits wireless users to receive DHCP settings when they first connect to the Aruba solution. What are the correct source and destination aliases for the rule?

Question19: Which Mobility Master (MM) dashboard should an administrator access to view a list of rogue and interfering APs?

Question20: What is a role fulfilled by an Aruba Mobility Master (MM)?

Question21: What does an Aruba Mobility Master (MM) do before it deploys a configuration to a Mobility Controller (MC)?

Question22: A network administrator examines a list of 2.4GHz clients with low performance in the Mobility Master (MM) dashboard. Which property for a client should pose a concern as a potential performance issue?

Question23: A network administrator examines a list of 2.4GHz clients with low performance in the Mobility Master (MM) dashboard. Which property for a client should pose a concern as a potential performance issue?

Question24: What is a requirement for the Dashboard > Traffic Analysis window on the Aruba Mobility Master (MM) to show data?

Question25: What is a key difference between an Aruba Air Monitor (AM) and an Aruba Spectrum Analyzer (SA)?

Question26: Refer to the exhibit.

A network administrator creates a guest WLAN on an Aruba Mobility Master (MM). The exhibit shows some of the settings for the WLAN.
How should the network administrator handle the Auth server settings?

Question27: Which APs operate in an autonomous or standalone mode?

Question28: Refer to the exhibit.

What describes the behavior for this WLAN?

Question29: Which type of authentication server should administrators select to authenticate users to a ClearPass server?

Question30: A network administrator reduces an AP radio transmit power from 18 dBm to 15 dBm. This is a loss of 3 dBms.
What is the current power as a percentage of the original power?

Question31: An Aruba solution has a WLAN that uses WPA2-Enterprise security. How are encryption keys dynamically managed for the wireless users?

Question32: A company has an Aruba solution that is monitored by AirWave. Several users have recurring connectivity and performance issues with their wireless clients.
How can network administrators use AirWave to minitor these clients more easily?

Question33: A company has a Mobility Master (MM)-based solution. How does a Mobility Controller (MC) behave if it loses contact with all MM nodes?

Question34: What is one difference between how a network administrator can monitor clients in the Mobility (MM) interface and in the AirWave Management Platform?

Question35: A customer has a large campus that requires 400 Aruba 335 APs to support a total of 20,000 wireless users and
12Gbps of traffic. Although the customer wants two controllers for redundancy, each controller must be able to support all of the APs and users on its own.
Which Aruba Mobility Controller models meet the customer requirements and DO NOT unnecessarily exceed them?

Question36: Which IEEE standard provides the highest transmission rates in the 5.0GHz frequency band?

Question37: Which settings can a Mobility Master (MM) deploy to Mobility Controllers (MCs) but master controllers CANNOT deploy to local controllers?

Question38: A company has an Aruba solution with a guest WLAN named exam_guest. A network administrator creates the guest WLAN with the wizard and does not change any of the default roles. The authentication server does not send particular role assignments for authorized users. The company wants to deny guest access to specific IP rnages after the guests authenticate.
For which role should the administrator create the rule to deny this traffic?

Question39: A company has an Aruba Mobility Master (MM)-based solution with a WLAN that assigns users to VLANs
10-19. The company wants the Aruba solution to act at Layer 3 to route wireless user traffic.
