1. 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?

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

Importing clients’ MAC addresses to configure known clients for MAC authentication more quickly

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

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

2. 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

o VLAN 4085 (system IP) = 10.20.4.21

o VLAN 20 (users) = 10.20.20.1

o VLAN 4094 (WAN) = 198.51.100.14

• Gateway 2

o VLAN 4085 (system IP) = 10.20.4.22

o VLAN 20 (users) = 10.20.20.2

o 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.

You are setting up the UBT zone on an AOS-CX switch.

Which IP addresses should you define in the zone?

Primary controller = 10.20.4.21; backup controller = 10.20.4.22

Primary controller = 198.51.100.14; backup controller = 10.20.4.21

Primary controller = 10.20.4.21; backup controller, not defined

Primary controller = 10.20.20.254; backup controller, not defined

3. Refer to the scenario.

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

Permitted to receive IP addresses with DHCP

Permitted access to DNS services from 10.8.9.7 and no other server

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

Denied access to other 10.0.0.0/8 subnets

Permitted access to the Internet

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

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

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 this configuration.

What is one change you must make 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”.)

In the “medical-mobile” policy, move rules 2 and 3 between rules 7 and 8.

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

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

In the “medical-mobile” policy, change the source in rule 8 to “user.”

4. 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?

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

Enable RadSec on the MCs’ RFC 3676 server config.

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

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

5. Refer to the scenario.

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

Permitted to receive IP addresses with DHCP

Permitted access to DNS services from 10.8.9.7 and no other server

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

Denied access to other 10.0.0.0/8 subnets

Permitted access to the Internet

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

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

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.

What setting not shown in the exhibit must you check to ensure that the requirements of the scenario are met?

That denylisting is enabled globally on the MCs’ firewalls

That stateful handling of traffic is enabled globally on the MCs’ firewalls and on the medical-mobile role

That AppRF and WebCC are enabled globally and on the medical-mobile role

That the MCs are assigned RF Protect licenses

6. 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

o VLAN 4085 (system IP) = 10.20.4.21

o VLAN 20 (users) = 10.20.20.1

o VLAN 4094 (WAN) = 198.51.100.14

• Gateway 2

o VLAN 4085 (system IP) = 10.20.4.22

o VLAN 20 (users) = 10.20.20.2

o 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 have configured the correct UBT zone and port-access role settings. However, the solution is not working.

What else should you make sure to do?

Assign VLAN 20 as the access VLAN on any edge ports to which tunneled clients might connect.

Create a new VLAN on the AOS-CX switch and configure that VLAN as the UBT client VLA

Assign sufficient VIA licenses to the gateways based on the number of wired clients that will connect.

Change the port-access auth-mode mode to client-mode on any edge ports to which tunneled clients might connect.

7. A company has Aruba gateways and wants to start implementing gateway IDS/IPS. The customer has selected Block for the Fail Strategy.

What might you recommend to help minimize unexpected outages caused by using this particular fall strategy?

Configuring a relatively high threshold for the gateway threat count alerts

Making sure that the gateways have formed a cluster and operate in default gateway mode

Setting the IDS or IPS policy to the least restrictive option, Lenient

Enabling alerts and email notifications for events related to gateway IPS engine utilization and errors

8. 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?

Report scheduling settings

Alert duration and threshold settings

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

The allowlist settings in the IDS policy

9. Refer to the scenario.

A customer is migrating from on-prem AD to Azure AD as its sole domain solution. The customer also manages both wired and wireless devices with Microsoft Endpoint Manager (Intune).

The customer wants to improve security for the network edge. You are helping the customer design a ClearPass deployment for this purpose. Aruba network devices will authenticate wireless and wired clients to an Aruba ClearPass Policy Manager (CPPM) cluster (which uses version 6.10).

The customer has several requirements for authentication. The clients should only pass EAP-TLS authentication if a query to Azure AD shows that they have accounts in Azure AD. To further refine the clients’ privileges, ClearPass also should use information collected by Intune to make access control decisions.

Assume that the Azure AD deployment has the proper prerequisites established.

You are planning the CPPM authentication source that you will reference as the authentication source in 802.1X services.

How should you set up this authentication source?

As Kerberos type

As Active Directory type

As HTTP type, referencing the Intune extension

AS HTTP type, referencing Azure AD's FQDN

10. Refer to the scenario.

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

Permitted to receive IP addresses with DHCP

Permitted access to DNS services from 10.8.9.7 and no other server

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

Denied access to other 10.0.0.0/8 subnets

Permitted access to the Internet

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

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

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’.)

In the “medical-mobile” policy, change the source in rule 1 to “user.”

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

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

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

11. What is a common characteristic of a beacon between a compromised device and a command and control server?

Use of IPv6 addressing instead of IPv4 addressing

Lack of encryption

Use of less common protocols such as SNAP

Periodic transmission of small, identically sized packets

12. Refer to the scenario.

A hospital has an AOS10 architecture that is managed by Aruba Central. The customer has deployed a pair of Aruba 9000 Series gateways with Security licenses at each clinic. The gateways implement IDS/IPS in IDS mode.

The Security Dashboard shows these several recent events with the same signature, as shown below:

Which step could give you valuable context about the incident?

View firewall sessions on the APs and record the threat sources’ type and O

View the user-table on APs and record the threat sources’ 802.11 settings.

View the RAPIDS Security Dashboard and see if the threat sources are listed as rogues.

Find the Central client profile for the threat sources and note their category and family.

13. 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

o VLAN 4085 (system IP) = 10.20.4.21

o VLAN 20 (users) = 10.20.20.1

o VLAN 4094 (WAN) = 198.51.100.14

• Gateway 2

o VLAN 4085 (system IP) = 10.20.4.22

o VLAN 20 (users) = 10.20.20.2

o 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.

What is one change that you should make to the solution?

Change the ubt-client-vlan to VLAN 13.

Configure edge ports in VLAN trunk mode.

Remove VLAN assignments from role configurations on the gateways.

Configure the UBT solution to use VLAN extend mode.

14. 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:

o VLAN 4094 (WAN) = 198.51.100.14

• Gateway 2

o VLAN 4085 (system IP) = 10.20.4.22

o VLAN 20 (users) = 10.20.20.2

o 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?

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

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

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

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

15. Refer to the scenario.

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

Permitted to receive IP addresses with DHCP

Permitted access to DNS services from 10.8.9.7 and no other server

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

Denied access to other 10.0.0.0/8 subnets

Permitted access to the Internet

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

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

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 line below shows the effective configuration for the role.

Apply the “apprf-medical-mobile-sacl" policy explicitly to the “medical-mobile” user-role under the “medical-mobile” policy.

In the “medical-mobile” policy, change the action for rules 2 and 3 to reject.

In the “medical-mobile” policy, move rule 5 under rule 6.

In the “medical-mobile” policy, change the subnet mask in rule 5 to 255.255.252.0.

16. A customer requires a secure solution for connecting remote users to the corporate main site. You are designing a client-to-site virtual private network (VPN) based on Aruba VIA and Aruba Mobility Controllers acting as VPN Concentrators (VPNCs). Remote users will first use the VIA client to contact the VPNCs and obtain connection settings.

The users should only be allowed to receive the settings if they are the customer's “Remote Employees” AD group. After receiving the settings, the VIA clients will automatically establish VPN connections, authenticating to CPPM with certificates.

What should you do to help ensure that only authorized users obtain VIA connection settings?

Set up the VPNCs' VIA web authentication profile to use CPPM as the authentication server; set up a service on CPPM that uses AD as the authentication source.

Set up the VPNCs' VIA web authentication profile to use an AD domain controller as the LDAP server.

Set up the VPNCs' VIA connection profile to use two authentication profiles, one RADIUS profile to CPPM and one LDAP profile to A

Set up the VPNCs' VIA connection profile to use one authentication profile, which is set to the AD domain controller's hostname.

17. Refer to the scenario.

A customer is migrating from on-prem AD to Azure AD as its sole domain solution. The customer also manages both wired and wireless devices with Microsoft Endpoint Manager (Intune).

The customer wants to improve security for the network edge. You are helping the customer design a ClearPass deployment for this purpose. Aruba network devices will authenticate wireless and wired clients to an Aruba ClearPass Policy Manager (CPPM) cluster (which uses version 6.10).

The customer has several requirements for authentication. The clients should only pass EAP-TLS authentication if a query to Azure AD shows that they have accounts in Azure AD. To further refine the clients’ privileges, ClearPass also should use information collected by Intune to make access control decisions.

The customer wants you to configure CPPM to collect information from Intune on demand during the authentication process.

What should you tell the Intune admins about the certificates issued to clients?

They must be issued by a well-known, trusted C

They must include the Intune ID in the subject name.

They must include the client MAC address in the subject name.

They must be issued by a ClearPass Onboard C

18. Refer to the scenario.
