HP Updated HPE6-A78 Exam Questions and Answers by dominik

In the context of ArubaOS-Switches, enabling Enhanced Secure mode has several benefits, one of which includes disabling insecure algorithms for protocols such as SSH. This is in line with security best practices, as older, less secure algorithms are known to be vulnerable to various types of cryptographic attacks. When Enhanced Secure mode is enabled, the switch automatically restricts the use of such algorithms, thereby enhancing the security of management access.

To configure the infrastructure to support network scans as part of the ClearPass Policy Manager (CPPM) solution, creating SNMPv3 users on ArubaOS-CX switches is necessary. Ensuring that the credentials for these SNMPv3 users match those configured on CPPM is crucial for enabling CPPM to perform network scans effectively. SNMPv3 provides a secure method for network management by offering authentication and encryption, which are essential for safely conducting scans that classify endpoints by type. This configuration allows CPPM to communicate securely with the switches and gather necessary data without compromising network security.

In the context of WPA3-Enterprise with EAP-TLS authentication, the error message "Client doesn’t support configured EAP methods" suggests that the client is not able to complete the EAP-TLS authentication process. EAP-TLS requires that both the server (in this case, CPPM) and the client have a valid certificate for mutual authentication. Windows 10 does support EAP-TLS natively, so options A, C, and D can be ruled out.

The most likely reason for the authentication failure is that the client device does not have the correct client certificate installed, which is required to establish a TLS session with the server. Therefore, ensuring that the client has a valid certificate installed that matches the server's requirements is the correct step to resolve this issue.

The Aruba ClearPass Device Insight Analyzer plays a crucial role within the Device Insight architecture by residing in the cloud and applying machine learning and supervised crowdsourcing to the metadata sent by Collectors. This component of the architecture is responsible for analyzing vast amounts of data collected from the network to identify and classify devices accurately. By utilizing machine learning algorithms and crowdsourced input, the Device Insight Analyzer enhances the accuracy of device detection and classification, thereby improving the overall security and management of the network.
