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?

• A. Set up qatewav clusters manually and set VRRP IP addresses for dynamic authorization.
• B. Enable default gateway mode for the gateway clusters.
• C. Chanqe the WLANs to mixed-mode forwardinq so that vou can select multiple qatewav clusters.
• D. Use auto-group clustering instead of auto-site clustering for the gateways.

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 created a role mapping policy as shown in the exhibits below.

What is one change that you need to make to this policy?

• A. Change the rules evaluation mechanism to first applicable.
• B. Change the default role to 'mobile-onboarded*
• C. Move rules 2 and 3 to the top of the list.
• D. In rule 1 change Subject-CN to Issuer-CN.

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. Disabling Telnet
• B. Changing the switch's DNS server to the mgmt VRF
• C. Either disabling DHCPv4-snoopinq or leaving it enabled, but also enabling ARP inspection
• D. Setting the clock manually instead of using NTP

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?

• A. Enabling control plane policing to automatically drop SNMP GET requests
• B. Adding an SNMP community with a long random name
• C. Enabling SNMPv3, which implicitly disables SNMPv1/v2
• D. Setting the snmp-server settings to "snmpv3-only"

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 an Unknown status.
• B. The entry shows a profile conflict of having a new profile of Computer for a profiled Printer.
• C. The entry shows multiple DHCP options under the fingerprints.
• D. The entry lacks a hostname or includes a hostname with long seemingly random characters.
