A company wants to turn on Wireless IDS/IPS infrastructure and client detection at the high level on HPE Aruba Networking APs. The company does not want to enable any prevention settings.

What should you explain about HPE Aruba Networking recommendations?

  1. HPE Aruba Networking recommends turning on both wired and wireless prevention whenever you enable detection at high.
  2. HPE Aruba Networking recommends using hybrid AP mode, as opposed to Air Monitors (AMs), when implementing detection without prevention.
  3. HPE Aruba Networking recommends disabling client detection when you configure infrastructure detection at high, as infrastructure detection includes all the client checks and more.
  4. HPE Aruba Networking recommends configuring infrastructure and client detection at a custom level and disabling or tuning some of the settings that are likely to produce false positives.

Answer(s): D

Explanation:

When enabling Wireless IDS/IPS infrastructure and client detection at a high level on HPE Aruba Networking APs without enabling prevention settings, HPE Aruba Networking recommends configuring detection at a custom level and adjusting settings to minimize false positives. This approach allows for effective monitoring while reducing the risk of unnecessary alerts and maintaining the accuracy of detections.

1. Custom Level Configuration: By customizing the detection settings, you can tailor the system to your specific environment, ensuring that only relevant threats are detected and reducing false positives.
2. False Positive Reduction: Disabling or tuning settings that are likely to produce false positives helps in maintaining the reliability of the detection system and prevents alert fatigue.
3. Focused Detection: Custom configuration ensures that the IDS/IPS focuses on critical detections, improving overall security posture.


Reference:

Aruba's Wireless IDS/IPS configuration guides and best practices emphasize the importance of customizing detection settings to balance security needs with operational efficiency, particularly when prevention features are not enabled.



Refer to Exhibit.



A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application). In the CPDI interface, you go to the Generic Devices page and see the view shown in the exhibit.

What correctly describes what you see?

  1. Each cluster is a group of unclassified devices that CPDI's machine learning has discovered to have similar attributes.
  2. Each cluster is a group of devices that match one of the tags configured by admins.
  3. Each cluster is all the devices that have been assigned to the same category by one of CPDI's built- in system rules.
  4. Each cluster is a group of devices that have been classified with user rules, but for which CPDI offers different recommendations.

Answer(s): A

Explanation:

In HPE Aruba Networking ClearPass Device Insight (CPDI), the clusters shown in the exhibit represent groups of unclassified devices that CPDI's machine learning algorithms have identified as having similar attributes. These clusters are formed based on observed characteristics and behaviors of the devices, helping administrators to categorize and manage devices more effectively.

1. Machine Learning: CPDI uses machine learning to analyze device attributes and group them into clusters based on similarities.
2. Unclassified Devices: These clusters typically represent devices that have not yet been explicitly classified by admins but share common attributes that suggest they belong to the same category.
3. Management: This clustering helps in simplifying the process of managing and applying policies to groups of similar devices.


Reference:

ClearPass Device Insight documentation on device clustering and machine learning provides detailed information on how devices are grouped into clusters based on observed attributes and behaviors.



A company has AOS-CX switches and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants switches to implement 802.1X
authentication to CPPM and download user roles.

What is one task that you must complete on the switches to support this use case?

  1. Specify CPPM as the RADIUS server with the exact CN in CPPM's HTTPS certificate.
  2. Install the root CA certificate for CPPM's RADIUS certificate in a TA profile on the switches.
  3. Configure empty user-roles with names that match enforcement profile names on CPPM.
  4. Specify a ClearPass username and password that match the name and RADIUS secret in a CPPM network device entry.

Answer(s): B

Explanation:

To support 802.1X authentication and download user roles from HPE Aruba Networking ClearPass Policy Manager (CPPM) on AOS-CX switches, you must install the root CA certificate for CPPM's RADIUS certificate in a Trust Anchor (TA) profile on the switches. This ensures that the switches trust the RADIUS server certificate presented by CPPM during the authentication process.

1. Root CA Certificate: Installing the root CA certificate ensures that the switch can verify the authenticity of the RADIUS server certificate provided by CPPM.
2. Trust Anchor Profile: The TA profile on the switch holds the root CA certificate, establishing a trust relationship between the switch and the CPPM RADIUS server.
3. Secure Authentication: This setup is essential for securing the 802.1X authentication process and enabling the download of user roles.


Reference:

AOS-CX switch configuration guides and ClearPass integration documentation detail the steps for installing root CA certificates and configuring trust anchor profiles to enable secure RADIUS authentication and role-based access control.



What is a benefit of Online Certificate Status Protocol (OCSP)?

  1. It lets a device query whether a single certificate is revoked or not.
  2. It lets a device dynamically renew its certificate before the certificate expires.
  3. It lets a device download all the serial numbers for certificates revoked by a CA at once.
  4. It lets a device determine whether to trust a certificate without needing any root certificates installed.

Answer(s): A

Explanation:

The benefit of the Online Certificate Status Protocol (OCSP) is that it allows a device to query whether a single certificate is revoked or not. OCSP provides a real-time mechanism for checking the revocation status of an individual certificate, enabling devices to verify the validity of certificates quickly and efficiently.

1. Certificate Status Query: OCSP enables devices to send a query to an OCSP responder to check the revocation status of a specific certificate.
2. Real-Time Verification: This protocol offers real-time responses, ensuring that the most up-to-date status of the certificate is obtained.
3. Efficiency: OCSP is more efficient than downloading an entire Certificate Revocation List (CRL), as it only queries the status of one certificate at a time.


Reference:

Documentation on certificate management and OCSP describes how OCSP works and its advantages in providing real-time certificate status checks compared to traditional CRLs.
