Refer to the scenario.
A customer has asked you to review their AOS-CX switches for potential vulnerabilities. The configuration for these switches is shown below:
What is one immediate remediation that you should recommend?
A. Changing the switch's DNS server to the mgmt VRF
B. Setting the clock manually instead of using NTP
C. Either disabling DHCPv4-snoopinq or leaving it enabled, but also enabling ARP inspection
D. Disabling Telnet
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?
A. The entry shows multiple DHCP options under the fingerprints.
B. The entry shows an Unknown status.
C. The entry shows a profile conflict of having a new profile of Computer for a profiled Printer.
D. The entry lacks a hostname or includes a hostname with long seemingly random characters.
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?
A. An app registration on Azure AD that references the CPPM's FQDN
B. Windows 365 subscriptions
C. CPPM's RADIUS certificate was imported as trusted in the Azure AD directory
D. Azure AD Domain Services
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.
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
On CPPM, you are creating the authentication method shown in the exhibit below:
You will use the method for standalone EAP-TLS and for inner methods in TEAP. What should you do?
A. Configure OCSP override and set the OCSP URL to localhost/onboard/mdps ocspphp/2
B. Enable certificate comparison.
C. Enable authorization.
D. Configure OCSP override and leave the OCSP URL blank.
Refer to the exhibit.
You have been given this certificate to install on a ClearPass server for the RADIUS/EAP and RadSec usages.
What is one issue?
A. The certificate has a wildcard in the subject common name.
B. The certificate uses a fully qualified the '.local" domain name.
C. The certificate does not have a URI subject alternative name
D. The certificate does not have an IP subject alternative name
Refer to the scenario.

You have created a role mapping policy as shown in the exhibits below.
What is one change that you need to make to this policy?
A. In rule 1 change Subject-CN to Issuer-CN.
B. Move rules 2 and 3 to the top of the list.
C. Change the rules evaluation mechanism to first applicable.
D. Change the default role to 'mobile-onboarded*
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?
A. Configuring a relatively high threshold for the gateway threat count alerts
B. Making sure that the gateways have formed a cluster and operate in default gateway mode
C. Setting the IDS or IPS policy to the least restrictive option, Lenient
D. Enabling alerts and email notifications for events related to gateway IPS engine utilization and errors
The customer needs a way for users to enroll new wired clients in Intune. The clients should have limited access that only lets them enroll and receive certificates. You plan to set up these rights in an AOS-CX role named "provision."
The customer's security team dictates that you must limit these clients' Internet access to only the necessary sites. Your switch software supports IPv4 and IPv6 addresses for the rules applied in the "provision" role.
What should you recommend?
A. Configuring the rules for the "provision" role with IPv6 addresses, which tend to be more stable
B. Enabling tunneling to the MCs on the "provision" role and then setting up the privileges on the MCs
C. Configuring the "provision" role as a downloadable user role (DUR) in CPPM
D. Assigning the "provision" role to a VLAN and then setting up the rules within a Layer 2 access control list (ACL)
