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.

Question # 2

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 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

Deny other clients access

# Other requirements

Communications between ClearPass servers and on-prem AD domain controllers must be encrypted.

# Network topology

# 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

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 # 4

Several AOS-CX switches are responding to SNMPv2 GET requests for the public community. The customer only permits SNMPv3. You have asked a network admin to fix this problem. The admin says, “I tried to remove the community, but the CLI output an error.”

What should you recommend to remediate the vulnerability and meet the customer’s requirements?

Enabling control plane policing to automatically drop SNMP GET requests

Setting the snmp-server settings to “snmpv3-only”

Adding an SNMP community with a long random name

Enabling SNMPv3, which implicitly disables SNMPv1/v2

Explanation:

This is because SNMPv3 is a secure version of SNMP that provides authentication, encryption, and access control for network management. SNMPv3-only is a configuration option on AOS-CX switches that disables SNMPv1 and SNMPv2c, which are insecure versions of SNMP that use plain text community strings for authentication. By setting the snmp-server settings to “snmpv3-only”, the switch will only respond to SNMPv3 requests and reject any SNMPv1 or SNMPv2c requests, thus remedying the vulnerability and meeting the customer’s requirements.

A. Enabling control plane policing to automatically drop SNMP GET requests. This is not a valid recommendation because control plane policing is a feature that protects the switch from denial-of-service (DoS) attacks by limiting the rate of traffic sent to the CPU. Control plane policing does not disable SNMPv1 or SNMPv2c, but rather applies a rate limit to all SNMP requests, regardless of the version. Moreover, control plane policing might also drop legitimate SNMP requests if they exceed the rate limit, which could affect the network management.

C. Adding an SNMP community with a long random name. This is not a valid recommendation because an SNMP community is a shared secret that acts as a password for accessing network devices using SNMPv1 or SNMPv2c. Adding an SNMP community with a long random name does not disable SNMPv1 or SNMPv2c, but rather creates another community string that can be used for authentication. Moreover, adding an SNMP community with a long random name does not improve the security of SNMPv1 or SNMPv2c, as the community string is still transmitted in plain text and can be intercepted by an attacker.

D. Enabling SNMPv3, which implicitly disables SNMPv1/v2. This is not a valid recommendation because enabling SNMPv3 does not implicitly disable SNMPv1 or SNMPv2c on AOS-CX switches. Enabling SNMPv3 only adds support for the secure version of SNMP, but does not remove support for the insecure versions. Therefore, enabling SNMPv3 alone does not remedy the vulnerability or meet the customer’s requirements.

Question # 5

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 # 6

Refer to the scenario.

A customer has an AOS10 architecture that is managed by Aruba Central. Aruba infrastructure devices authenticate clients to an Aruba ClearPass cluster.

In Aruba Central, you are examining network traffic flows on a wireless IoT device that is categorized as “Raspberry Pi” clients. You see SSH traffic. You then check several more wireless IoT clients and see that they are sending SSH also.

You want a relatively easy way to communicate the information that an IoT client has used SSH to Aruba CPPM.

What is one prerequisite?

Enable event processing on subscribers in the ClearPass cluster.

In CPPM's CA trust list, add the Aruba Infrastructure usage to the DigiCert certificate.

Obtain a data collector token from Central's platform integration settings.

Create an API application and token within the REST API settings.

Question # 7

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.

Question # 8

You are reviewing an endpoint entry in ClearPass Policy Manager (CPPM) Endpoints Repository.

What is a good sign that someone has been trying to gain unauthorized access to the network?

The entry shows multiple DHCP options under the fingerprints.

The entry shows an Unknown status.

The entry shows a profile conflict of having a new profile of Computer for a profiled Printer.

The entry lacks a hostname or includes a hostname with long seemingly random characters.

Question # 9

A customer has an AOS 10 architecture, which includes Aruba APs. Admins have recently enabled WIDS at the high level. They also enabled alerts and email notifications for several events, as shown in the exhibit.

Admins are complaining that they are getting so many emails that they have to ignore them, so they are going to turn off all notifications.

What is one step you could recommend trying first?

Send the email notifications directly to a specific folder, and only check the folder once a week.

Disable email notifications for Roque AP, but leave the Infrastructure Attack Detected and Client Attack Detected notifications on.

Change the WIDS level to custom, and enable only the checks most likely to indicate real threats.

Disable just the Rogue AP and Client Attack Detected alerts, as they overlap with the Infrastructure Attack Detected alert.

Explanation:

According to the AOS 10 documentation1, WIDS is a feature that monitors the radio spectrum for the presence of unauthorized, rogue access points and the use of wireless attack tools. WIDS can be configured at different levels, such as low, medium, high, or custom. The higher the level, the more checks are enabled and the more alerts are generated. However, not all checks are equally relevant or indicative of real threats. Some checks may generate false positives or unnecessary alerts that can overwhelm the administrators and reduce the effectiveness of WIDS.

Therefore, one step that could be recommended to reduce the number of email notifications is to change the WIDS level to custom, and enable only the checks most likely to indicate real threats. This way, the administrators can fine-tune the WIDS settings to suit their network environment and security needs, and avoid getting flooded with irrelevant or redundant alerts. Option C is the correct answer.

Option A is incorrect because sending the email notifications directly to a specific folder and only checking the folder once a week is not a good practice for security management. This could lead to missing or ignoring important alerts that require immediate attention or action. Moreover, this does not solve the problem of getting too many emails in the first place.

Option B is incorrect because disabling email notifications for Rogue AP, but leaving the Infrastructure Attack Detected and Client Attack Detected notifications on, is not a sufficient solution. Rogue APs are unauthorized access points that can pose a serious security risk to the network, as they can be used to intercept or steal sensitive data, launch attacks, or compromise network performance. Therefore, disabling email notifications for Rogue APs could result in missing critical alerts that need to be addressed.

Option D is incorrect because disabling just the Rogue AP and Client Attack Detected alerts, as they overlap with the Infrastructure Attack Detected alert, is not a valid assumption. The Infrastructure Attack Detected alert covers a broad range of attacks that target the network infrastructure, such as deauthentication attacks, spoofing attacks, denial-of-service attacks, etc. The Rogue AP and Client Attack Detected alerts are more specific and focus on detecting and classifying rogue devices and clients that may be involved in such attacks. Therefore, disabling these alerts could result in losing valuable information about the source and nature of the attacks.

Question # 10

A customer has an AOS 10-based solution, including Aruba APs. The customer wants to use Cloud Auth to authenticate non-802.1X capable IoT devices.

What is a prerequisite for setting up the device role mappings?

Configuring a NetConductor-based fabric

Configuring Device Insight (client profile) tags in Central

Integrating Aruba ClearPass Policy Manager (CPPM) and Device Insight

Creating global role-to-role firewall policies in Central
