You are setting up an HPE Aruba Networking VIA solution for a company. You need to configure access control policies for applications and resources that remote clients can access when connected to the VPN.

Where on the VPNC should you configure these policies?

  1. In the tunneled network settings within the VIA Connection Profile
  2. In the cloud security settings using IPsec maps
  3. In the roles to which VIA clients are assigned after IKE authentication
  4. In the roles to which VIA clients are assigned after VIA Web authentication

Answer(s): C

Explanation:

To configure access control policies for applications and resources that remote clients can access when connected to the VPN, you should configure these policies in the roles to which VIA clients are assigned after IKE (Internet Key Exchange) authentication on the VPNC. These roles define the permissions and access controls for the clients once they are authenticated, ensuring that they can only access the applications and resources allowed by their assigned roles.

1. IKE Authentication: After IKE authentication, clients are assigned specific roles that determine their access privileges.

2. Role-Based Access Control: By configuring access control policies within these roles, you can granularly control what resources and applications the remote clients can access over the VPN.
3. Security: This method ensures that access is managed securely and dynamically based on the role assigned to each client after successful authentication.


Reference:

Aruba's VPN and VIA deployment guides provide detailed instructions on configuring roles and access control policies for remote VPN clients.



A company has HPE Aruba Networking APs running AOS-10 and managed by HPE Aruba Networking

Central. The company also has AOS-CX switches. The security team wants you to capture traffic from a particular wireless client. You should capture this client's traffic over a 15 minute time period and then send the traffic to them in a PCAP file.

What should you do?

  1. Go to the client's AP in HPE Aruba Networking Central. Use the "Security" page to run a packet capture.
  2. Access the CLI for the client's AP. Set up a mirroring session between its radio and a management station running Wireshark.
  3. Access the CLI for the client's AP's switch. Set up a mirroring session between the AP's port and a management station running Wireshark.
  4. Go to that client in HPE Aruba Networking Central. Use the "Live Events" page to run a packet capture.

Answer(s): A

Explanation:

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.


Reference:

Aruba Central's documentation and user guides detail the steps for performing packet captures through the Central interface, including capturing traffic from specific clients and generating PCAP files for analysis.



Assume that an AOS-CX switch is already implementing DHCP snooping and ARP inspection successfully on several VLANs.

What should you do to help minimize disruption time if the switch reboots?

  1. Configure the switch to act as an ARP proxy.
  2. Create static IP-to-MAC bindings for the DHCP and DNS servers.
  3. Save the IP-to-MAC bindings to external storage.
  4. Configure the IP helper address on this switch, rather than a core routing switch.

Answer(s): C

Explanation:

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.


Reference:

Aruba's AOS-CX configuration guides and best practices for DHCP snooping and ARP inspection detail the importance of saving IP-to-MAC bindings for maintaining network security across reboots.



You need to create a rule in an HPE Aruba Networking ClearPass Policy Manager (CPPM) role mapping policy that references a ClearPass Device Insight Tag.

Which Type (namespace) should you specify for the rule?

  1. Application
  2. Tips
  3. Device
  4. Endpoint

Answer(s): D

Explanation:

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.


Reference:

ClearPass documentation and role mapping policy guides provide details on using Device Insight tags and the appropriate namespaces for creating effective policy rules.
