Question 1

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

Accepted Answer

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.

Question 2

You are establishing a cluster of HPE Aruba Networking ClearPass servers. (Assume that they are
running version 6.9.).
For which type of certificate is it recommended to install a CA-signed certificate on the Subscriber
before it joins the cluster?

Accepted Answer

A

Explanation: When setting up a ClearPass cluster, it is critical to ensure secure communication between the cluster nodes and the client devices. For this purpose, certain certificates must be properly configured. 1. Why HTTPS Requires a CA-Signed Certificate? HTTPS communication is used for inter-cluster communication and for the web-based user interface that administrators use to manage the ClearPass cluster. Before joining the cluster, it is strongly recommended to install a CA-signed HTTPS certificate on the Subscriber to ensure secure communication and prevent warnings/errors due to untrusted certificates. Without a CA-signed certificate, the Subscriber might use a self-signed certificate, leading to security risks and lack of trust validation. 2. Analysis of Other Certificate Types B . Database: Incorrect: Database communications within ClearPass clusters are secured using internal certificates or keys. These are not user-facing and do not require a CA-signed certificate before joining the cluster. C . RADIUS/EAP: Incorrect: RADIUS/EAP certificates are important for client authentication, but they are not required on the Subscriber prior to cluster joining. These can be configured after the Subscriber is part of the cluster. D . RadSec: Incorrect: RadSec is an optional feature for secure RADIUS communication over TLS, and its certificate configuration is typically performed post-cluster setup. Final Recommendation To ensure secure cluster operations and seamless web-based management, a CA-signed HTTPS certificate should be installed on the Subscriber before it joins the ClearPass cluster.
