Exhibit 1

Exhibit 2

Exhibit 3

A network administrator creates a guest WLAN on an Aruba Mobility Manager (MM). The exhibits show some of the settings for the WLAN. The administrator does not change the policies for those roles.
How does the firewall control guest clients when they first connect to the WLAN?

Question8: Refer to the exhibits.
Exhibit 1

Exhibit 2

Network administrators use the Aruba Mobility Master (MM) wizard to create a WLAN and do not manually alter any of the profiles for that WLAN. The exhibits show some of the settings for the WLAN. Some wireless users cannot successfully connect to the WLAN. Network administrators attempt to connect on their own machines with a test account, and the connection is successful. They attempt to connect with the same account on user clients, and the connection fails.
Which issue could prevent authentication from completing correctly?

Question9: Refer to the exhibit.

What is a valid way to help the APs discover devices that can control them?

Question10: Which task can an Aruba Spectrum Monitor (SM) perform?

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 matches traffic from these clients to the user any any permit rule, what does it do?

Question12: 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?

Question13: How can network administrators upgrade AirMatch on an Aruba Mobility Master (MM)?

Question14: What is the minimum space between channels in the 2.4GHz range to prevent overlap?

Question15: An Aruba solution runs ArubaOS 8 and uses a standalone controller architecture. Which feature can administrators use to optimize the channel and power plan for the APs?

Question16: 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?

Question17: A network administrator monitors an Aruba Mobility Controller with Aruba AirWave and sees the configuration status is Error. What should the administrator conclude?

Question18: Which pre-defined role allows DHCP, DNS, and internal captive portal redirection for a guest WLAN?

What is the current power as a percentage of the original power?

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

Which settings must the administrator configure on each Mobility Controller (MC) at the device level for this configuration to function properly?

Question25: A company deploys an Aruba wireless solution for the first time. In which deployment is clustering supported?

Question26: What is an example of a Layer2 wireless threat that a wireless intrusion detection system (WIDS) should detect?

Question27: Which IEEE standard provides the highest transmission rates in the 5.0GHz frequency band?

Question28: An Aruba Remote AP (RAP) operates in split-tunnel mode. How does the AP forward traffic?

Question29: Refer to the exhibit.

An Aruba solution uses AirMatch with the default AirMatch profile settings. A network administrator sees that a scheduled optimization was completed, but a plan was not deployed.
Based on the exhibit, why did this occur?

Question30: A company plans to deploy a Mobility Master (MM). The MM will manage 50 Mobility Controller (MC) appliances that will control a total of 680 APs, and 10 Virtual Mobility Controllers (VMCs) that will control a total of 160 APs.
How many MM licenses does the company require?

Question31: A network administrator configures this policy:

Users to which this policy applies are unable to receive IP addresses with DHCP. How should the administrator fix the issue?

Question32: How does WPA2 protect wireless user traffic in the air?

Question33: A company currently uses 802.11ac Wave 1 as a wireless solution. They want to upgrade to 802.11ac Wave2.
Which new feature will now be available with this upgrade?

Question34: Which Mobility Master (MM) dashboard should an administrator access to view a list of rogue and interfering APs?

Question35: Refer to the exhibit.

Which role must AP 1 play?

For which role should the administrator create the rule to deny this traffic?

Question46: Refer to the exhibit.

The alias in the rule shown in the exhibit is network 10.1.1.0/24.
A wireless client is assigned IP address 10.1.2.10/24 and the "admins" role. The wireless client at 10.1.2.10 attempts to initiate a Web session with a server at 10.1.1.2. A wired client at 10.1.1.3 attempts to initiate an SSH session with the wireless client at 10.1.2.10.
How does the Aruba firewall handle these attempts?

Question48: Refer to the exhibit.

The exhibit shows the AAA profile for a WLAN on an Aruba solution. This WLAN uses 802.1X to authenticate users to a RADIUS server. A user successfully authenticates with 802.1X, but the RADIUS server does not send a role assignment.
How does the Aruba firewall handle the role assignment for this user?

Question49: 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.
