HP HPE7-A02 Dumps Questions Answers

To minimize disruption time if an AOS-CX switch reboots while implementing DHCP snooping and ARP inspection, you should save the IP-to-MAC bindings to external storage. This ensures that the DHCP snooping and ARP inspection tables, which are crucial for preventing spoofing attacks, are preserved across reboots. When the switch restarts, it can reload these bindings from the external storage, thereby maintaining network security and reducing the downtime associated with rebuilding these tables.

1.Preserving Bindings: Saving IP-to-MAC bindings to external storage ensures that these critical security tables are not lost during a reboot, maintaining network integrity.

2.Security Continuity: This practice helps to quickly restore security features like DHCP snooping and ARP inspection, minimizing the window of vulnerability.

3.Operational Efficiency: By preserving these bindings, the switch can resume normal operations faster, reducing disruption to network services.

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.

When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA-signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in the cluster and provides a trusted certificate for client connections.

1.HTTPS Security: A CA-signed certificate for HTTPS ensures that all web-based communication to and from the ClearPass server is encrypted and secure.

2.Cluster Communication: Secure communication between ClearPass nodes in the cluster is essential for synchronization and data integrity.

3.Client Trust: Clients accessing the ClearPass server will trust the CA-signed certificate, avoiding security warnings and ensuring smooth operations.
