HP HPE6-A78 Exam With Confidence Using Practice Dumps

The image indicates that there is an issue with the user role assignment, which is key to network access in ArubaOS. If the user role name sent by CPPM doesn't match any of the roles defined in the ArubaOS, then the user will be assigned a default or incorrect role that does not have the necessary permissions, thus leading to the connection errors and lack of Internet access. Ensuring that the role names are consistent between CPPM and ArubaOS can resolve this issue.

The thumbprint (also known as a fingerprint) of a certificate or SSH key is a hash that uniquely represents the public key contained within. When you first connect to the switch with SSH from a management station, you should ensure that the thumbprint matches what you expect. This is a security measure to confirm the identity of the device you are connecting to and to ensure that a man-in-the-middle (MITM) attack is not occurring. If the thumbprint matches the known good thumbprint of the switch, it is safe to proceed with the connection.

To enable managers to use certificates to log into the Web UI of an Aruba Mobility Controller (MC), where Aruba ClearPass Policy Manager (CPPM) acts as the external server for authentication, it is essential to ensure that the MC trusts the HTTPS certificate used by CPPM. This involves uploading a trusted CA certificate to the MC that matches the one used by CPPM. Additionally, configuring a username and password for CPPM on the MC might be necessary to secure and facilitate communication between the MC and CPPM. This setup ensures that certificate-based authentication is securely validated, maintaining secure access control for the Web UI.
