A company has AOS-CX switches and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants switches to implement 802.1Xauthentication to CPPM and download user roles.What is one task that you must complete on the switches to support this use case?
Answer(s): B
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.
AOS-CX switch configuration guides and ClearPass integration documentation detail the steps for installing root CA certificates and configuring trust anchor profiles to enable secure RADIUSauthentication and role-based access control.
What is a benefit of Online Certificate Status Protocol (OCSP)?
Answer(s): A
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.
Documentation on certificate management and OCSP describes how OCSP works and its advantages in providing real-time certificate status checks compared to traditional CRLs.
Refer to the exhibit.(Note that the HPE Aruba Networking Central interface shown here might look slightly different from what you see in your HPE Aruba Networking Central interface as versions change; however, similar concepts continue to apply.)An HPE Aruba Networking 9x00 gateway is part of an HPE Aruba Networking Central group that has the settings shown in the exhibit. What would cause the gateway to drop traffic as part of its IDPS settings?
In the exhibit, the HPE Aruba Networking Central settings for the 9x00 gateway show that traffic inspection is enabled, and the gateway is set to operate in IDS (Intrusion Detection System) mode with the fail strategy set to "Block". This configuration means that the gateway will drop traffic if it matches a rule in the active ruleset.1.Active Ruleset: The ruleset version 9861 is active, and the gateway is configured to automatically update the ruleset daily.2.Traffic Matching Rules: When traffic matches a rule in the active ruleset, it is flagged as suspicious or malicious.3.Block Mode: Since the fail strategy is set to "Block", any traffic that matches a rule in the active ruleset will be dropped to prevent potential threats.
The documentation for HPE Aruba Networking Central and gateway IDS/IPS configuration provides detailed information on how traffic is inspected and the implications of different fail strategies, including blocking traffic that matches the active ruleset.
A company has wired VolP phones, which transmit tagged traffic and connect to AOS-CX switches. The company wants to tunnel the phones' traffic to an HPEAruba Networking gateway for applying security policies.What is part of the correct configuration on the AOS-CX switches?
Answer(s): D
To tunnel VoIP phone traffic from AOS-CX switches to an HPE Aruba Networking gateway, you need to configure a User-Based Tunneling (UBT) reserved VLAN on the switches. This VLAN is dedicated for tunneling purposes and ensures that the VoIP traffic is correctly identified and tunneled to the gateway where security policies can be applied.1.UBT Configuration: Setting a UBT reserved VLAN ensures that the switch knows which VLAN to use for tunneling traffic to the gateway.2.Traffic Tunneling: The reserved VLAN helps in segregating the VoIP traffic, ensuring it is handled securely and according to the configured policies at the gateway.3.Policy Application: By tunneling the traffic, the gateway can apply advanced security policies to the VoIP traffic.
Aruba's AOS-CX and UBT configuration guides detail the steps for setting up reserved VLANs for tunneling traffic to gateways.
You are establishing a cluster of HPE Aruba Networking ClearPass servers. (Assume that they are running version 6.9.).For which type of certificate it is recommended to install a CA-signed certificate on the Subscriber before it joins the cluster?
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.
ClearPass documentation and best practices for clustering and certificate management recommend installing CA-signed certificates for secure HTTPS communication.
