HP HPE7-A02 Practice Test - Questions Answers

To capture traffic from a particular wireless client for a 15-minute period and then send the traffic in a PCAP file, you should go to the client's AP in HPE Aruba Networking Central and use the 'Security' page to run a packet capture. This method allows you to directly capture the client's traffic from the AP managing the wireless connection, ensuring that you gather the relevant traffic data for analysis.

1. Centralized Management: HPE Aruba Networking Central provides a centralized interface for managing and monitoring APs, making it easy to initiate packet captures.

2. Security Page: The 'Security' page in Aruba Central includes tools for running packet captures, allowing you to specify the duration and other parameters.

3. Ease of Use: This approach simplifies the process by using the built-in features of Aruba Central, avoiding the need for complex CLI commands or additional hardware.

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.

When creating a rule in an HPE Aruba Networking ClearPass Policy Manager (CPPM) role mapping policy that references a ClearPass Device Insight Tag, you should specify the 'Endpoint' Type (namespace) for the rule. This ensures that the policy can properly reference and utilize the tags assigned to endpoints by ClearPass Device Insight for making role mapping decisions.

1. Endpoint Tags: ClearPass Device Insight assigns tags to endpoints based on their characteristics and behaviors. These tags are stored in the 'Endpoint' namespace.

2. Role Mapping: By referencing the 'Endpoint' type, the rule can accurately match endpoints with the specified tags and apply the appropriate role mappings based on the device's profile.

3. Policy Consistency: Ensuring that the correct namespace is used maintains consistency and accuracy in role assignment policies.

When configuring 802.1X authentication on edge ports of an AOS-CX switch and assigning VoIP phones to a 'voice' role, the correct approach is to configure VLAN 12 as the allowed trunk VLAN in the 'voice' role. This setup ensures that traffic tagged for VLAN 12 is appropriately managed by the role applied to the VoIP phones. In AOS-CX switches, the role-based VLAN configuration allows for more granular control and ensures that the VoIP phones' traffic is handled correctly without altering the edge port settings, which typically operate with default settings for authentication.

To set up HPE Aruba Networking ClearPass Policy Manager (CPPM) for certificate-based authentication of 802.1X supplicants, you need to upload the root CA certificate as a Trusted CA with the EAP usage. This configuration allows the ClearPass server to validate the certificates presented by the supplicants during the 802.1X authentication process. By marking the certificate for EAP usage, ClearPass can properly authenticate the supplicant devices using the trusted certificate authority (CA) that issued their certificates.

To support the detection of denial of service (DoS) attacks on AOS-CX switches, deploying an NAE (Network Analytics Engine) agent to monitor control plane policing (CoPP) is the best approach. NAE agents provide real-time analytics and monitoring capabilities, allowing administrators to detect anomalies and potential DoS attacks, such as ping or ARP floods, more quickly and efficiently. Control plane policing helps protect the switch's CPU from unnecessary or malicious traffic, and the NAE agent can alert administrators when thresholds are exceeded, providing a proactive measure to detect and mitigate DoS attacks.

When the Active Endpoint Security Report on HPE Aruba Networking ClearPass indicates that endpoints have MAC addresses but no known IP addresses, one effective step to address this issue is to add CPPM's (ClearPass Policy Manager) IP address to the IP helper list on routing switches. This configuration ensures that DHCP requests are forwarded to the ClearPass server, allowing it to track and report the IP addresses assigned to the endpoints. This helps ClearPass maintain an accurate mapping of MAC addresses to IP addresses, improving endpoint visibility and security management.

To ensure that the AOS-CX switch properly assigns the 'employees' role when using CPPM (ClearPass Policy Manager) as the RADIUS server, you should configure a RADIUS Enforcement profile on CPPM with the Aruba-User-Role VSA (Vendor-Specific Attribute) set to 'employees'. This configuration ensures that when an endpoint authenticates, CPPM sends the appropriate role assignment to the AOS-CX switch, which then applies the corresponding policies and VLAN settings defined for the 'employees' role.

To show the security team information about MAC spoofing attempts detected by HPE Aruba Networking ClearPass Policy Manager (CPPM), you should use ClearPass Insight to run an Active Endpoint Security report. ClearPass Insight provides comprehensive reporting capabilities that include detailed information on security incidents, such as MAC spoofing attempts. By generating this report, you can provide the security team with a clear overview of the detected spoofing activities, including the endpoints involved and the context of the events.
