55. Frage
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?
Antwort: C
Begründung:
* 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.
56. Frage
A company assigns a different block of VLAN IDs to each of its access layer AOS-CX switches. The switches run version 10.07. The IDs are used for standard purposes, such as for employees, VolP phones, and cameras. The company wants to apply 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM) and then steer clients to the correct VLANs for local forwarding.
What can you do to simplify setting up this solution?
Antwort: D
Begründung:
To simplify the setup of 802.1X authentication with HPE Aruba Networking ClearPass Policy Manager (CPPM) and ensure clients are steered to the correct VLANs for local forwarding, you should assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference these names. This approach allows for a more straightforward configuration and management process, as the user roles can apply consistent policies based on VLAN names rather than specific IDs. It also helps in maintaining clarity and reducing errors in VLAN assignments across different switches.
57. Frage
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?
Antwort: C
Begründung:
Integrating HPE Aruba Networking ClearPass Policy Manager (CPPM) and HPE Aruba Networking ClearPass Device Insight (CPDI) can help a company implement Zero Trust Security by allowing CPDI to use tags to inform CPPM that clients are using prohibited applications.
CPPM can then take action, such as telling the network infrastructure to quarantine those clients, ensuring that only compliant and trusted devices have network access.
1. Device Insight Tags: CPDI can monitor client behavior and tag devices that are using prohibited applications.
2. Policy Enforcement: CPPM can use these tags to apply specific enforcement actions, such as quarantining non-compliant devices.
3. Zero Trust Implementation: This integration supports Zero Trust Security by ensuring that all devices are continuously monitored and controlled based on their behavior and compliance with security policies.
58. Frage
A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server to authenticate managers on its AOS-CX switches. The company wants CPPM to control which commands managers are allowed to enter.
Which service must you add to the managers' TACACS+ enforcement profile?
Antwort: A
Begründung:
To control which commands managers are allowed to execute on AOS-CX switches using ClearPass Policy Manager (CPPM) as a TACACS+ server, you must configure the Shell service in the TACACS+ enforcement profile. The Shell service provides the ability to define granular access controls for commands. It supports policy-driven command authorization, which is essential in controlling administrative tasks based on roles.

* Official HPE Aruba ClearPass documentation on TACACS+ integration and command authorization.
* Industry best practices for AAA (Authentication, Authorization, and Accounting) configuration in network security architectures.
59. Frage
A company has HPE Aruba Networking APs (AOS-10), which authenticate clients to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM is set up to receive a variety of information about clients' profile and posture. New information can mean that CPPM should change a client's enforcement profile.
What should you set up on the APs to help the solution function correctly?
Antwort: C
Begründung:
To ensure that HPE Aruba Networking APs (AOS-10) properly interact with HPE Aruba Networking ClearPass Policy Manager (CPPM) and dynamically update a client's enforcement profile based on new profile and posture information, you should enable Dynamic Authorization in the RADIUS server settings for CPPM. This allows ClearPass to send Change of Authorization (CoA) requests to the APs, prompting them to reapply the appropriate enforcement profiles based on updated information.
1.Dynamic Authorization: Enabling this feature allows ClearPass to dynamically push changes to the APs whenever there is new relevant information about a client's profile or posture.
2.Change of Authorization (CoA): This mechanism ensures that clients are assigned the correct enforcement profiles in real-time, based on the latest data.
3.Enhanced Policy Enforcement: This setup helps in maintaining accurate and up-to-date policy enforcement for clients on the network.
Reference: ClearPass and AOS-10 documentation on RADIUS server settings and dynamic authorization explain the process and benefits of enabling Dynamic Authorization for real-time policy updates.
