Questions 5

Refer to the scenario.

A customer has an Aruba ClearPass cluster. The customer has AOS-CX switches that implement 802.1X authentication to ClearPass Policy Manager (CPPM).

Switches are using local port-access policies.

The customer wants to start tunneling wired clients that pass user authentication only to an Aruba gateway cluster. The gateway cluster should assign these clients to the "eth- internet" role. The gateway should also handle assigning clients

to their VLAN, which is VLAN 20.

The plan for the enforcement policy and profiles is shown below:

The gateway cluster has two gateways with these IP addresses:

Gateway 1

1.

VLAN 4085 (system IP) = 10.20.4.21

2.

VLAN 20 (users) = 10.20.20.1

3.

VLAN 4094 (WAN) = 198.51.100.14

Gateway 2

1.

VLAN 4085 (system IP) = 10.20.4.22

2.

VLAN 20 (users) = 10.20.20.2

3.

VLAN 4094 (WAN) = 198.51.100.12

VRRP on VLAN 20 = 10.20.20.254

The customer requires high availability for the tunnels between the switches and the gateway cluster. If one gateway falls, the other gateway should take over its tunnels. Also, the switch should be able to discover the gateway cluster regardless of whether one of the gateways is in the cluster.

Assume that you are using the "myzone" name for the UBT zone.

Which is a valid minimal configuration for the AOS-CX port-access roles?

A. port-access role eth-internet gateway-zone zone myzone gateway-role eth-user

B. port-access role internet-only gateway-zone zone myzone gateway-role eth-internet

C. port-access role eth-internet gateway-zone zone myzone gateway-role eth-internet vlan access 20

D. port-access role internet-only gateway-zone zone myzone gateway-role eth-internet vlan access 20

Questions 6

A company has an Aruba ClearPass server at 10.47.47.8, FQDN radius.acnsxtest.local. This exhibit shows ClearPass Policy Manager's (CPPM's) settings for an Aruba Mobility Controller (MC).

The MC is already configured with RADIUS authentication settings for CPPM, and RADIUS requests between the MC and CPPM are working. A network admin enters and commits this command to enable dynamic authorization on the MC:

aaa rfc-3576-server 10.47.47.8

But when CPPM sends CoA requests to the MC, they are not working. This exhibit shows the RFC 3576 server statistics on the MC:

How could you fix this issue?

A. Change the UDP port in the MCs' RFC 3576 server config to 3799.

B. Enable RadSec on the MCs' RFC 3676 server config.

C. Configure the MC to obtain the time from a valid NTP server.

D. Make sure that CPPM is using an ArubaOS Wireless RADIUS CoA enforcement profile.

Questions 7

A company has Aruba gateways that are Implementing gateway IDS/IPS in IDS mode. The customer complains that admins are receiving too frequent of repeat email notifications for the same threat. The threat itself might be one that the admins should investigate, but the customer does not want the email notification to repeat as often.

Which setting should you adjust in Aruba Central?

A. Report scheduling settings

B. Alert duration and threshold settings

C. The IDS policy setting (strict, medium, or lenient)

D. The allowlist settings in the IDS policy

Questions 8

Refer to the scenario.

A customer requires these rights for clients in the "medical-mobile" AOS firewall role on Aruba Mobility Controllers (MCs):

1.

Permitted to receive IP addresses with DHCP

2.

Permitted access to DNS services from 10.8.9.7 and no other server

3.

Permitted access to all subnets in the 10.1.0.0/16 range except denied access to 10.1.12.0/22

4.

Denied access to other 10.0.0.0/8 subnets

5.

Permitted access to the Internet

6.

Denied access to the WLAN for a period of time if they send any SSH traffic

7.

Denied access to the WLAN for a period of time if they send any Telnet traffic

8.

Denied access to all high-risk websites

External devices should not be permitted to initiate sessions with "medical-mobile" clients, only send return traffic.

The exhibits below show the configuration for the role.

There are multiple issues with the configuration.

What is one of the changes that you must make to the policies to meet the scenario requirements? (In the options, rules in a policy are referenced from top to bottom. For example, "medical-mobile" rule 1 is "ipv4 any any svc-dhcp permit," and rule 8 is "ipv4 any any any permit'.)

A. In the "medical-mobile" policy, change the source in rule 1 to "user."

B. In the "medical-mobile" policy, change the subnet mask in rule 3 to 255.255.248.0.

C. In the "medical-mobile" policy, move rules 6 and 7 to the top of the list.

D. Move the rule in the "apprf-medical-mobile-sacl" policy between rules 7 and 8 in the "medical-mobile" policy.

Questions 9

You are working with a developer to design a custom NAE script for a customer. You are helping the developer find the correct REST API resource to monitor.

Refer to the exhibit below.

What should you do before proceeding?

A. Go to the v1 API documentation interface instead of the v10.10 interface.

B. Use your Aruba passport account and collect a token to use when trying out API calls.

C. Enable the switch to listen to REST API calls on the default VRF.

D. Make sure that your browser is set up to store authentication tokens and cookies.

Questions 10

You are designing an Aruba ClearPass Policy Manager (CPPM) solution for a customer. You learn that the customer has a Palo Alto firewall that filters traffic between clients in the campus and the data center.

Which integration can you suggest?

A. Sending Syslogs from the firewall to CPPM to signal CPPM to change the authentication status for misbehaving clients

B. Importing clients' MAC addresses to configure known clients for MAC authentication more quickly

C. Establishing a double layer of authentication at both the campus edge and the data center DMZ

D. Importing the firewall's rules to program downloadable user roles for AOS-CX switches more quickly

Questions 11

A customer needs you to configure Aruba ClearPass Policy Manager (CPPM) to authenticate domain users on domain computers. Domain users, domain computers, and domain controllers receive certificates from a Windows CA. CPPM should validate these certificates and verify that the users and computers have accounts in Windows AD. The customer requires encryption for all communications between CPPM and the domain controllers.

You have imported the root certificate for the Windows CA to the ClearPass CA Trust list.

Which usages should you add to it based on these requirements?

A. Radec and Aruba infrastructure

B. EAP and AD/LDAP Server

C. EAP and Radsec

D. LDAP and Aruba infrastructure
