A company wants to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to profile Linux devices. You have decided to schedule a subnet scan of the devices' subnets. Which additional step should you complete before scheduling the scan?
Subnet Scan Requirements for Profiling:
For ClearPass to scan and profile devices in a subnet, the Data Port must be enabled on the ClearPass server and connected to the network.
This ensures that ClearPass can send and receive the required packets for device discovery and profiling.
Option Analysis:
Option A: Incorrect. SSH accounts are not required for subnet scanning.
Option B: Incorrect. WMI probing is for Windows systems, not Linux devices.
Option C: Correct. The Data Port is essential for subnet scans and must be properly configured and connected.
Option D: Incorrect. SNMP is used for network device monitoring, not Linux device profiling.
A company wants to apply role-based access control lists (ACLs) on AOS-CX switches, which are implementing authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants to centralize configuration as much as possible. Which correctly describes your options?
Centralized Role Configuration on CPPM:
CPPM can assign roles to clients dynamically during authentication.
However, the actual ACL policies (e.g., firewall policies) must already exist and be referenced locally on the switch.
CPPM cannot directly configure ACL details on AOS-CX switches.
Option Analysis:
Option A: Correct. The role is defined on CPPM, but it references a policy pre-configured on the switch.
Option B: Incorrect. This does not align with Aruba's centralized role-based access control design.
Option C: Incorrect. CPPM cannot configure the ACL policies and classes directly; they must exist locally.
Option D: Incorrect. Policies can be referenced centrally but not fully configured on CPPM.
The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?
To follow best security practices for 802.1X authentication settings in Windows domain clients:
Specify at least two server names under 'Connect to these servers':
Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
Select the desired Trusted Root Certificate Authority and 'Don't prompt users':
Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
Enabling 'Don't prompt users' ensures end users are not confused or tricked into accepting certificates from untrusted servers.
Why the other options are incorrect:
Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
Option D: Incorrect. Clearing 'Use simple certificate selection' requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
Server Validation: Specify the exact RADIUS server names in the 'Connect to these servers' field.
Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
User Prompts: Enable 'Don't prompt users' to enforce automatic and secure authentication without user intervention.
A company uses both HPE Aruba Networking ClearPass Policy Manager (CPPM) and HPE Aruba Networking ClearPass Device Insight (CPDI). What is one way integrating the two solutions can help the company implement Zero Trust Security?
Integration of CPDI and CPPM for Zero Trust:
CPDI (ClearPass Device Insight) identifies and profiles devices and applications on the network.
CPDI can tag devices based on their behavior or detected applications.
CPPM uses these tags to enforce policies, such as quarantining clients that violate security rules (e.g., using prohibited applications).
Option Analysis:
Option A: Incorrect. CPPM does not inform CPDI about role assignments; CPDI provides device context to CPPM.
Option B: Correct. CPDI tags clients, and CPPM uses those tags to enforce quarantine or other Zero Trust actions.
Option C: Incorrect. Custom fingerprint definitions are not part of this integration.
Option D: Incorrect. CPDI provides information about devices, not user identities.
An AOS-CX switch has been configured to implement UBT to two HPE Aruba Networking gateways that implement VRRP on the users' VLAN. What correctly describes how the switch tunnels UBT users' traffic to those gateways?
User-Based Tunneling (UBT) with VRRP:
UBT allows traffic from authenticated users to be tunneled to an HPE Aruba Networking gateway.
In the case of VRRP, where two gateways are configured for redundancy, the AOS-CX switch will always send the traffic to the primary gateway defined in the UBT zone configuration.
The VRRP state (master/backup) does not impact the UBT decision; the UBT primary configuration takes precedence.
Option Analysis:
Option A: Incorrect. UBT does not strictly follow the VRRP master; it adheres to the UBT primary gateway configuration.
Option B: Correct. The switch tunnels all traffic to the primary gateway configured in the UBT zone.
Option C: Incorrect. UBT does not load-share traffic between gateways.
Option D: Incorrect. UBT uses the primary gateway configured in the UBT zone, not dynamically determined active devices.
