Authentic HP Certification Exam HPE6-A88 Questions Answers

Certificate trust is hierarchical. For a client device to trust a server certificate, it must trust the Root CA that signed it. If an internal CA is used, its root certificate is not present in the default trust stores of consumer devices. Therefore, the administrator must deploy that root certificate to every client (typically via GPO, MDM, or Onboard) so they can successfully verify the identity of the ClearPass server during the EAP handshake.

Unlike agent-based solutions where the client initiates contact, Agentless OnGuard requires ClearPass to "reach out" to the Windows endpoint using WMI and SMB. For ClearPass to have the necessary permissions to perform these remote administrative tasks on domain-joined machines, the ClearPass Policy Manager server must itself be joined to the Active Directory domain . This allows the server to use domain administrator or service account credentials to authenticate against the target endpoints.

In a ClearPass cluster, the Publisher is the central "Source of Truth" for all configuration and licensing data. While Subscriber nodes handle the actual authentication traffic, they receive their policy and license updates via replication from the Publisher. Therefore, all license management —including adding new license keys or re-allocating capacity—must be performed on the Publisher's web interface.
