What are the correct source and destination aliases for the rule?

source = any and destination = user

source = any and destination = any

Define the Employee and Sales roles as internal roles, and then configure the rules as global rules for internal users.

Apply these rules as a subnet-based policy, and then ensure that only Employee and Sales users are assigned IP addresses in that subnet.

Select either the Employee or Sales role, and then configure these rules within the global policy.

Create a policy with these rules, and then apply that policy to the Employee and Sales roles.

23. An Aruba Mobility Master (MM)-based solution has a WLAN that uses WPA2-Enterprise security. A test login on a wireless client fails.

25. Refer to the exhibit.

The exhibit shows output from a Mobility Master (MM) dashboard.

What does the health status indicate?

It takes the AP about twice as long to send data to the client as expected if all transmissions succeeded.

About half of the heartbeats the client sends reaches the Mobility Manager (MM).

The maximum data rate that 802.11ac supports is about twice as high as the data rate the client uses.

The client device only complies with about half of the rules in the endpoint health policy.

26. 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?

It drops traffic from wireless clients in both the 10.10.0/24 subnet and 10.10.20.0/24 subnet.

It permits traffic from wireless clients in both the 10.10.10.0/24 and 10.10.20.0/24 subnet as long as the packet has a source I

firewall application rules

28. Refer to the exhibits.

Exhibit 1

Exhibit 2

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?

The shared key configured for the ClearPass server is incorrect.

The RADIUS server is not correctly set up to send a user role for the employee account.

MAC authentication is enabled on the WLAN, and the test device does not have an authorized address.

The administrators entered the wrong password for the employee account.

Place APs in different buildings in different AP Groups.

Assign APs in different buildings to different MM nodes.

Configure APs in different buildings to use different frequency bands.

Assign different radio profiles to APs in different buildings.

30. What is one difference between captive portal authentication and 802.1X authentication?

802.1X authentication always authenticates the wireless client, while captive portal authentication always authenticates the wireless user.

802.1X authentication occurs at Layer 2, while captive portal authentication occurs at Layer 3.

802.1X authentication must use an LDAP server, while captive portal authentication can use a RADIUS server or an LDAP server.

802.1X authentication is typically implemented without encryption, while captive authentication is often combined with WPA or WPA2.

33. 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?

In the master-local architecture, all traffic is tunneled to the master controller to handle. In a MM architecture, all traffic is tunneled to the MM to handle.

In both architectures, APs forward corporate user traffic locally and tunnel guest user traffic to a Mobility Controller (MC) to handle.

In both architectures, traffic is tunneled to a Mobility Controller (MC) to handle.

In the master-local architecture, traffic is tunneled to a local Mobility Controller (MC) to handle. In a MM architecture, all traffic is tunneled to the MM to handle.
