QUESTION 33
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

QUESTION 34
You are setting up Aruba ClearPass Policy Manager (CPPM) to enforce EAP-TLS authentication with Active Directory as the authentication source. The company wants to prevent users with disabled accounts from connecting even if those users still have valid certificates.
As the first part of meeting these criteria, what should you do to enable CPPM to determine where accounts are enabled in AD or not?

Add an Endpoint Context Server to the domain controller with actions for querying the domain controller for account status.

Enable OCSP in the EAP-TLS authentication method settings and configure an OCSP override to the domain controller FQDN.

Add a custom attribute for userAccountControl to the filters in the AD authentication source.

Install a Microsoft Active Directory extension in Aruba ClearPass Guest and set up an HTTP authentication source that points to that extension.

QUESTION 35
Refer to the scenario.
# Introduction to the customer
You are helping a company add Aruba ClearPass to their network, which uses Aruba network infrastructure devices.
The company currently has a Windows domain and Windows CA. The Window CA issues certificates to domain computers, domain users, and servers such as domain controllers. An example of a certificate issued by the Windows CA is shown here.

The company is in the process of adding Microsoft Endpoint Manager (Intune) to manage its mobile clients.
The customer is maintaining the on-prem AD for now and uses Azure AD Connect to sync with Azure AD.
# Requirements for issuing certificates to mobile clients
The company wants to use ClearPass Onboard to deploy certificates automatically to mobile clients enrolled in Intune. During this process, Onboard should communicate with Azure AD to validate the clients. High availability should also be provided for this scenario; in other words, clients should be able to get certificates from Subscriber 2 if Subscriber 1 is down.
The Intune admins intend to create certificate profiles that include a UPN SAN with the UPN of the user who enrolled the device.
# Requirements for authenticating clients
The customer requires all types of clients to connect and authenticate on the same corporate SSID.
The company wants CPPM to use these authentication methods:
* EAP-TLS to authenticate users on mobile clients registered in Intune
* TEAR, with EAP-TLS as the inner method to authenticate Windows domain computers and the users on them To succeed, EAP-TLS (standalone or as a TEAP method) clients must meet these requirements:
Their certificate is valid and is not revoked, as validated by OCSP
The client’s username matches an account in AD
# Requirements for assigning clients to roles
After authentication, the customer wants the CPPM to assign clients to ClearPass roles based on the following rules:
* Clients with certificates issued by Onboard are assigned the “mobile-onboarded” role
* Clients that have passed TEAP Method 1 are assigned the “domain-computer” role Clients in the AD group “Medical” are assigned the “medical-staff” role Clients in the AD group “Reception” are assigned to the “reception-staff” role The customer requires CPPM to assign authenticated clients to AOS firewall roles as follows:
* Assign medical staff on mobile-onboarded clients to the “medical-mobile” firewall role
* Assign other mobile-onboarded clients to the “mobile-other” firewall role
* Assign medical staff on domain computers to the “medical-domain” firewall role
* All reception staff on domain computers to the “reception-domain” firewall role
* All domain computers with no valid user logged in to the “computer-only” firewall role
* Deny other clients access
# Other requirements
Communications between ClearPass servers and on-prem AD domain controllers must be encrypted.
# Network topology
For the network infrastructure, this customer has Aruba APs and Aruba gateways, which are managed by Central. APs use tunneled WLANs, which tunnel traffic to the gateway cluster. The customer also has AOS-CX switches that are not managed by Central at this point.

# ClearPass cluster IP addressing and hostnames
A customer’s ClearPass cluster has these IP addresses:
* Publisher = 10.47.47.5
* Subscriber 1 = 10.47.47.6
* Subscriber 2 = 10.47.47.7
* Virtual IP with Subscriber 1 and Subscriber 2 = 10.47.47.8
The customer’s DNS server has these entries
* cp.acnsxtest.com = 10.47.47.5
* cps1.acnsxtest.com = 10.47.47.6
* cps2.acnsxtest.com = 10.47.47.7
* radius.acnsxtest.com = 10.47.47.8
* onboard.acnsxtest.com = 10.47.47.8
You cannot see flow attributes for wireless clients.
What should you check?

Deep packet inspection is enabled on the role to which the Aruba APs assign the wireless clients.

Firewall application visibility is enabled on the Aruba gateways, and the gateways have been rebooted.

Gateway IDS/IPS is enabled on the Aruba gateways, and the gateways have been rebooted.

Deep packet inspection is enabled on the Aruba Aps, and the APs have been rebooted.

QUESTION 36
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 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

QUESTION 37
Refer to the scenario.
An organization wants the AOS-CX switch to trigger an alert if its RADIUS server (cp.acnsxtest.local) rejects an unusual number of client authentication requests per hour. After some discussions with other Aruba admins, you are still not sure how many rejections are usual or unusual. You expect that the value could be different on each switch.
You are helping the developer understand how to develop an NAE script for this use case.
You are helping the developer find the right URI for the monitor.
Refer to the exhibit.

You have used the REST API reference interface to submit a test call. The results are shown in the exhibit.
Which URI should you give to the developer?

/rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics

/rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics?attributes=a

/rest/v1/system/vrfs/mgmt/radius/_servers/cp.acnsxtest.local/2083/tcp

/rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics.access_rejec

QUESTION 38
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

Explanation
The correct answer is D. Enabling alerts and email notifications for events related to gateway IPS engine utilization and errors.
Gateway IDS/IPS is a feature that allows the Aruba gateways to monitor and block malicious or unwanted traffic based on predefined or custom rules 1. The Fail Strategy is a setting that determines how the gateways handle traffic when the IPS engine fails or crashes 2. The Block option means that the gateways will stop forwarding traffic until the IPS engine recovers, while the Bypass option means that the gateways will continue forwarding traffic without inspection 2.
The Block option provides more security, but it also increases the risk of network outages if the IPS engine fails frequently or for a long time 2. To minimize this risk, it is recommended to enable alerts and email notifications for events related to gateway IPS engine utilization and errors 3. This way, the network administrators can be informed of any issues with the IPS engine and take appropriate actions to restore or troubleshoot it 3.
The other options are not correct or relevant for this issue:
Option A is not correct because configuring a relatively high threshold for the gateway threat count alerts would not help minimize unexpected outages caused by using the Block option. The gateway threat count alerts are used to notify the network administrators of the number of threats detected by the IPS engine, but they do not affect how the gateways handle traffic when the IPS engine fails 4.
Option B is not correct because making sure that the gateways have formed a cluster and operate in default gateway mode would not help minimize unexpected outages caused by using the Block option.
The gateway cluster mode is used to provide high availability and load balancing for the gateways, but it does not affect how the gateways handle traffic when the IPS engine fails . The default gateway mode is used to enable routing and NAT functions on the gateways, but it does not affect how the gateways handle traffic when the IPS engine fails .
Option C is not correct because setting the IDS or IPS policy to the least restrictive option, Lenient, would not help minimize unexpected outages caused by using the Block option. The IDS or IPS policy is used to define what rules are applied by the IPS engine to inspect and block traffic, but it does not affect how the gateways handle traffic when the IPS engine fails 2. The Lenient option contains fewer and older rules than the Moderate or Strict options, which means that it provides less security and more false negatives .

radius.acnsxtest.com = 10.47.47.8
onboard.acnsxtest.com = 10.47.47.8
The customer needs a secure way for users to enroll their new wireless clients in Intune. You are recommending a new WLAN that will provide the users with limited access for the enrollment.
You have set up captive portal for clients on this WLAN to a web page with instructions for enrolling devices.
You will need to add several hostnames to the captive portal allowlist manually.
What is one of those hostnames?

The hostname used by ClearPass Policy ManaGer’s RADIUS services

The ClearPass Onboard hostname referenced in an Onboard provisioninG profile

The ClearPass Onboard hostname referenced in Intune SCEP profiles

The hostname used by the on-prem domain controllers

QUESTION 40
You are working with a developer to design a custom NAE script for a customer. The NAE agent should trigger an alert when ARP inspection drops packets on a VLAN. The customer wants the admins to be able to select the correct VLAN ID for the agent to monitor when they create the agent.
What should you tell the developer to do?

Use this variable, %{vlan-id} when defining the monitor URI in the NAE agent script.

Define a VLAN ID parameter; reference that parameter when defining the monitor URI.

Create multiple monitors within the script from which admins can select when they create the agent.

Use a callback action to collect the ID of the VLAN on which admins have enabled NAE monitoring.

QUESTION 41
Refer to the scenario.
A customer is using an AOS 10 architecture with Aruba APs and Aruba gateways (two per site). Admins have implemented auto-site clustering for gateways with the default gateway mode disabled. WLANs use tunneled mode to the gateways.
The WLAN security is WPA3-Enterprise with authentication to an Aruba ClearPass Policy Manager (CPPM) cluster VIP. RADIUS communications use RADIUS, not RadSec.
CPPM is using the service shown in the exhibits.

Which step can you take to improve operations during a possible gateway failover event?

Chanqe the WLANs to mixed-mode forwardinq so that vou can select multiple qatewav clusters.

Set up qatewav clusters manually and set VRRP IP addresses for dynamic authorization.

Use auto-group clustering instead of auto-site clustering for the gateways.

Enable default gateway mode for the gateway clusters.

QUESTION 42
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 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.

QUESTION 43
You need to install a certificate on a standalone Aruba Mobility Controller (MC). The MC will need to use the certificate for the Web UI and for implementing RadSec with Aruba ClearPass Policy Manager. You have been given a certificate with these settings:
Subject: CN=mc41.site94.example.com
* No SANs
* Issuer: CN=ca41.example.com
EKUs: Server Authentication, Client Authentication
What issue does this certificate have for the purposes for which the certificate is intended?

It has conflicting EKUs.

It is issued by a private CA.

It specifies domain info in the CN field instead of the DC field.

It lacks a DNS SAN.

QUESTION 44
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?

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 the scenario requirements?

EAP and AD/LDAP Server

LDAP and Aruba infrastructure

Radsec and Aruba infrastructure

EAP and Radsec

QUESTION 47
Refer to the scenario.
This customer is enforcing 802.1X on AOS-CX switches to Aruba ClearPass Policy Manager (CPPM). The customer wants switches to download role settings from CPPM. The “reception-domain” role must have these settings:
– Assigns clients to VLAN 14 on switch 1, VLAN 24 on switch 2, and so on.
– Filters client traffic as follows:
– Clients are permitted full access to 10.1.5.0/24 and the Internet
– Clients are denied access to 10.1.0.0/16
The switch topology is shown here:

How should you configure the VLAN setting for the reception role?

Assign a consistent name to VLAN 14, 24, or 34 on each access layer switch and reference that name in the enforcement profile VLAN settings.

Configure the enforcement profile as a downloadable role, but specify only the role name and leave the VLAN undefined. Then define a ‘reception’ role with the correct VLAN setting on each individual access layer switch.

Assign a number-based ID to the access layer switches. Then use this variable in the enforcement profile VLAN settings: %(NAS-ID]4.

Create a separate enforcement profile with a different VLAN ID for each switch. Add all profiles to the profile list in the appropriate enforcement policy rule.

QUESTION 48
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.

QUESTION 49
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.
You are planning to use Azure AD as the authentication source in 802.1X services.
What should you make sure that the customer understands is required?

An app registration on Azure AD that references the CPPM’s FQDN

Windows 365 subscriptions

CPPM’s RADIUS certificate was imported as trusted in the Azure AD directory

Azure AD Domain Services

QUESTION 50
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.

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 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

QUESTION 51
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

QUESTION 52
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.

QUESTION 53
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 OS.

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.
