HPE6-A84 Online Practice Questions and Answers

You want to use Device Insight tags as conditions within CPPM role mapping or enforcement policy rules.

What guidelines should you follow?

A. Create an HTTP authentication source to the Central API that queries for the tags. To use that source as the type for rule conditions, add it an authorization source for the service in question.

B. Use the Application type for the rule conditions; no extra authorization source is required for services that use policies with these rules.

C. Use the Endpoints Repository type for the rule conditions; Add Endpoints Repository as a secondary authentication source for services that use policies with these rules.

D. Use the Endpoint type for the rule conditions; no extra authorization source is required for services that use policies with these rules.

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 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".)

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

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

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

D. In the "medical-mobile" policy, change the source in rule 8 to "user."

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?

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

B. /rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatisti cs?attributes=access_rejects

When would you implement BPDU protection on an AOS-CX switch port versus BPDU filtering?

A. Use BPDU protection on edge ports to protect against rogue devices when the switch implements MSTP; use BPDU filtering to protect against rogue devices when the switch implements PVSTP+.

B. Use BPDU protection on edge ports to prevent rogue devices from connecting; use BPDU filtering on inter-switch ports for specialized use cases.

C. Use BPDU protection on inter-switch ports to ensure that they are selected as root; use BPDU filtering on edge ports to prevent rogue devices from connecting.

D. Use BPDU protection on edge ports to permanently lock out rogue devices; use BPDU filtering on edge ports to temporarily lock out rogue devices.

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?

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

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

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

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

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?

A. Enable event processing on subscribers in the ClearPass cluster.

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

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

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

Refer to the exhibit.

Which IP address should you record as a possibly compromised client?

A. 10.1.26.151

B. 10.1J.100

C. 10.1.26.1

D. 10.254.1.21

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:

1.

EAP-TLS to authenticate users on mobile clients registered in Intune

2.

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:

1.

Their certificate is valid and is not revoked, as validated by OCSP

2.

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:

1.

Clients with certificates issued by Onboard are assigned the "mobile-onboarded" role

2.

Clients that have passed TEAP Method 1 are assigned the "domain-computer" role

3.

Clients in the AD group "Medical" are assigned the "medical-staff" role

4.

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:

1.

Assign medical staff on mobile-onboarded clients to the "medical-mobile" firewall role

2.

Assign other mobile-onboarded clients to the "mobile-other" firewall role

3.

Assign medical staff on domain computers to the "medical-domain" firewall role

4.

All reception staff on domain computers to the "reception-domain" firewall role

5.

All domain computers with no valid user logged in to the "computer-only" firewall role

6.

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:

1.

Publisher = 10.47.47.5

2.

Subscriber 1 = 10.47.47.6

3.

Subscriber 2 = 10.47.47.7

4.

Virtual IP with Subscriber 1 and Subscriber 2 = 10.47.47.8

The customer's DNS server has these entries

1.

cp.acnsxtest.com = 10.47.47.5

2.

cps1.acnsxtest.com = 10.47.47.6

3.

cps2.acnsxtest.com = 10.47.47.7

4.

radius.acnsxtest.com = 10.47.47.8

5.

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?

A. EAP and AD/LDAP Server

B. LDAP and Aruba infrastructure

C. Radsec and Aruba infrastructure

D. EAP and Radsec

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
