Question1: A network manager wants to implement an Aruba wireless solution that accomodates 802.1X with EAP- TLS. All wireless users will utilize Active Directory (AD) accounts to authenticate.
Which device will the authenticator forward the authentication requests to in this type of solution?

Question2: Which authentication server option would the network administrator choose to authenticate a wireless user directly against an Active Directory (AD) domain controller without NPS or IAS?

Question3: A company has an Aruba solution. A network administrator wants to prevent wireless users from accessing shopping web sites with a bad reputation.
What should thee administrator set up to deny such traffic?

Question4: 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?

Question5: 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?

Question6: A customer has a large campus that requires 400 Aruba 335 APs to support a total of 10,000 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?

Question7: An Aruba solution runs ArubaOS 8 and uses a mobility master architecture. Which feature can network administrators use to balance wireless devices across APs on different channels?

What should the administrator do to meet this goal?

Question12: What is the difference between WPA and WPA2 encryption?

Question13: A company has a Mobility Master (MM)-based solution. There is a hardware issue with the MM appliance, and, as result, all connectivity is lost between the appliance and the network. The network manager is concerned about how this will impact licensing.
How will the Mobility Controller (MC) be affected?

Question14: Refer to the exhibits.
Exhibit 1

Exhibit 2

A company has an Aruba solution. Client 1 is assigned to the users1 role, and client 2 is assigned to the users2 role. The exhibits show current firewall rules for those roles. The network1 alias used to be
10.1.1.0/24, but the network administrator now changes the network1 alias to 172.16.1.0/24. Client 1 and Client 2 both send a packet destined to 172.16.1.10.

Question21: 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?

Question22: 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.
What must network administrators configure to permit the solution to forward traffic correctly?

Question23: 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 mathces traffic from these clients to the user any any permitrule, what does it do?

Question24: Which feature is unique to 802.11ac Wave 2 access points?
