Question1: A company deploys a wireless network in a typical office environment with many surfaces where the signal can bounce. Which 802.11 technology uses the characteristics of this environment to increase wireless speeds?

Question2: Assume that administrators accept the default forwarding mode for WLANs. How does wireless user traffic flow in a master-local architecture, and how does it flow in a Mobility Master (MM) architecture?

Question3: A network administrator creates an employee WLAN on an Aruba solution that uses WLAN WPA2- Enterprise security and an external RADIUS server. When the administrator tests the WLAN, the test client receives limited connectivity and cannot access any resources, but the RADIUS server shows that the user authenticated successfully.
What should the administrator check as a possible source of this issue?

Question4: Network administrators use the wizard to create a WLAN that uses WPA2-Enterprise security to a RADIUS server at 10.21.98.55. They do not manually change any settings.
Which device determines the EAP type that the wireless clients must support?

Question5: A network administrator has installed PEF licenses in the global pool of a Mobility Master (MM) solution.
When the administrator tries to configure roles and policies, an error indicates that the PEF licnese must be installed.
What should the administrator do to correct this issue?

Question6: A company has an Aruba solution and wants to provide guests with wireless access. The company wants to assign guests IP addresses in subnets that exist only within the Aruba solution.
Which feature should network administrators set up so guests can send traffic on the Internet without changes to the company routing solution?

Question7: Which settings can a Mobility Master (MM) deploy to Mobility Controllers (MCs) but master controllers CANNOT deploy to local controllers?

Question8: What is one difference between captive portal authentication and 802.1X authentication?

Question9: 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?

Question10: 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?

Question11: 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?

Question12: A company has an Aruba Mobility Master (MM)-based solution. Where can network administrators look to monitor the health status of all controllers, APs, and clients?

Question13: Refer to the exhibits.
Exhibit 1

Exhibit 2

An Aruba solution supports a WLAN that uses WPA2-Enterprise security. Exhibit 1 shows the AAA policy for the WLAN. Users are supposed to be assigned to different roles after authentication. Network administrators test a connection with the employee user account. Exhibit 2 shows the status for the client after this test.
What is a possible reason for the issue shown in Exhibit 2?

Question14: Which Mobility Master (MM) dashboard should an administrator access to view a list of rogue and interfering APs?

Question15: 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?

Question16: Refer to the exhibit.

The exhibit shows output from a Mobility Master (MM) dashboard. What does the health status indicate?

Question17: A network administrator wants to use unique digital certificates installed on user devices to authenticate wireless users. Which EAP method should the RADIUS server and clients support?

Question18: How does a high-gain omni-directional antenna compare to a typical omni-directional antenna?

Question19: Wich type of authentication server should administrators select to authenticate useres to a ClearPass server?

Question20: What is a key difference between an Aruba Air Monitor (AM) and an Aruba Spectrum Analyzer (SA)?

Question21: What is one difference between how administrators can use the Mobility Master (MM) Interface as compared to the AirWave Management Platform?

Question22: A company has an Aruba solution. The company wants to host a guest login portal with this solution, and the login portal must gie guests the option to create their own login accounts.
How can a network administrator help meet these criteria?

Question23: A company has a Mobility Master (MM)-based solution. How does a Mobility Controller (MC) behave if it loses conatct with all MM nodes?

Question24: 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?

Question25: 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?

Question26: 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?

Question27: 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?

Question28: What does an Aruba Mobility Master (MM) do before it deploys a configuration to a Mobility Controller (MC)?

Question29: Refer to the exhibit.

A network administrator sets up the Exam_Employees WLAN on an Aruba solution with a default role of guest, as shown in the exhibit. To which users does the guest role apply?

Question30: A company has a single Aruba Mobility Master (MM)-based solution with two Mobility Controllers (MCs).
Network administrators want APs in building 1 to support a WLAN but do not want APs in building 2 to support the WLAN.
How can administrator ensure that they can enforce this rule as they set up the WLAN in the Mobility Master (MM) Interface?

Question31: Refer to the exhibit.

What describes the behavior for this WLAN?
