  A. Add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches.

  ---

  Explanation

  To support the requirement for HPE Aruba Networking ClearPass Policy Manager (CPPM) to have HTTP User-Agent strings for profiling devices, you should add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches. This configuration ensures that DHCP requests and other relevant client traffic are forwarded to CPPM, allowing it to capture HTTP User-Agent strings and use them for device profiling.

  1.IP Helper Configuration: Adding CPPM to the IP helper list ensures that the switch forwards DHCP and other client traffic to CPPM, enabling it to gather necessary information for profiling. 2.User-Agent Strings: By receiving client traffic, CPPM can analyze HTTP headers and capture User-Agent strings, which provide valuable information about the client's device and browser. 3.Profiling Support: This approach supports the comprehensive profiling of devices, allowing CPPM to apply appropriate policies based on detailed device information.

• Question 3:

  You are setting up an HPE Aruba Networking VIA solution for a company. You have already created a VPN pool with IP addresses for the remote clients. During tests, however, the clients do not receive IP addresses from that pool. What is one setting to check?

  A. That the pool uses valid, public IP addresses that are assigned to the company
  B. That the pool is associated with the role to which the VIA clients are being assigned That
  C. the pool uses an IP subnet that is different from any subnet configured on the VPNC That
  D. the pool is referenced in the clients' VIA Connection Profile
  B. That the pool is associated with the role to which the VIA clients are being assigned That

  ---

  Explanation

  If VIA clients are not receiving IP addresses from the configured VPN pool, one setting to check is whether the pool is associated with the role to which the VIA clients are being assigned. The association between the IP pool and the role

  ensures that clients assigned to that role receive IP addresses from the correct pool.

  1.Role Association: Each role can be associated with a specific IP pool, ensuring that clients assigned to the role receive addresses from the intended pool.

  2.IP Allocation: Proper configuration of the IP pool and its association with the role is crucial for correct IP address allocation.

  3.VIA Configuration: Ensuring that all settings, including IP pool associations, are correctly configured, facilitates seamless client connectivity.

  C. Identifying issues with authenticating and authorizing clients
  D. Using WMI to collect additional information about Windows domain clients
  A. Using DHCP fingerprints to determine a client's device category and OS

  ---

  Explanation

  Running periodic subnet scans on devices from HPE Aruba Networking ClearPass Policy Manager (CPPM) can be used to gather DHCP fingerprints, which help determine a client's device category and operating system. DHCP fingerprints

  are unique patterns in DHCP request packets that provide valuable information about the device type and OS, assisting in device profiling and policy enforcement.

  1.DHCP Fingerprinting: This technique captures specific details from DHCP packets to identify the type and operating system of a device.

  2.Device Profiling: By running subnet scans, CPPM can continuously update its device database with accurate profiles, ensuring that policies are applied correctly based on the device type.

  3.Network Visibility: Regular scanning helps maintain up-to-date visibility of all devices on the network, improving security and management.

• Question 5:

  A company wants to apply role-based access control lists (ACLs) on AOS-CX switches, which are implementing authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants to centralize configuration as much as possible. Which correctly describes your options?

  A. You can configure the role on CPPM; however, the CPPM role must reference a policy name that is configured on the switch.
  B. You can configure the role name on CPPM; however, the role settings, including policy and classes, must be configured locally on the switch.
  C. You can configure the role, its policy, and the classes referenced in the policy all on CPPM.
  D. You can configure the role and its policy on CPPM; however, the classes referenced in the policy must
  A. You can configure the role on CPPM; however, the CPPM role must reference a policy name that is configured on the switch.

  ---

  Explanation

  Centralized Role Configuration on CPPM:

  CPPM can assign roles to clients dynamically during authentication.

  However, the actual ACL policies (e.g., firewall policies) must already exist and be referenced locally on the switch .

  CPPM cannot directly configure ACL details on AOS-CX switches.

  Option Analysis:

  Option A: Correct. The role is defined on CPPM, but it

  References: a policy pre-configured on the switch.

  Option B: Incorrect. This does not align with Aruba's centralized role-based access control design.

  Option C: Incorrect. CPPM cannot configure the ACL policies and classes directly; they must exist locally.

  Option D: Incorrect. Policies can be referenced centrally but not fully configured on CPPM.

• Question 6:

  A company has Aruba APs that are controlled by Central and that implement WIDS. When you check WIDS events, you see a "detect valid SSID misuse" event. What can you interpret from this event, and what steps should you take?

  A. Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat.
  B. Admins have likely misconfigured SSID security settings on some of the company's APs. You should have them check those settings.
  C. Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event.
  D. This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it.
  C. Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event.

  ---

  Explanation

  The "Detect Valid SSID Misuse" event in Aruba's Wireless Intrusion Detection System (WIDS) indicates that a valid SSID, associated with your network, is being broadcast from an unauthorized source. This scenario often signals a potential rogue access point attempting to deceive clients into connecting to it (e.g., for credential harvesting or man-in-the-middle attacks).

  1.

  Explanation of Each Option

  A. Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat:

  Incorrect:

  This event is not related to authentication failures by legitimate clients.

  Misconfigured authentication settings would lead to events like "authentication failures" or "radius issues," not "valid SSID misuse."

  B. Admins have likely misconfigured SSID security settings on some of the company's APs. You should have them check those settings:

  Incorrect:

  This event refers to an external device broadcasting your SSID, not misconfiguration on the company's authorized APs.

  WIDS differentiates between valid corporate APs and rogue APs.

  C. Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event:

  Correct:

  This is the most likely cause of the "detect valid SSID misuse" event. A rogue AP broadcasting a corporate SSID could lure clients into connecting to it, exposing sensitive credentials or traffic.

  Immediate action includes:

  Using the radio information from the event logs to identify the rogue AP's location.

  Physically locating and removing the rogue device.

  Strengthening WIPS/WIDS policies to prevent further misuse.

  D. This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it:

  Incorrect:

  While false positives are possible, "valid SSID misuse" is a critical security event that should not be ignored.

  Delaying action increases the risk of successful attacks against your network.

  2. Recommended Steps to Address the Event

  Review Event Logs:

  Gather details about the rogue AP, such as SSID, MAC address, channel, and signal strength.

  Locate the Rogue Device:

  Use the detecting AP's radio information and signal strength to triangulate the rogue AP's physical location.

  Respond to the Threat:

  Remove or disable the rogue device.

  Notify the security team for further investigation.

  Prevent Future Misuse:

  Strengthen security policies, such as enabling client whitelists or enhancing WIPS protection.

• Question 7:

  A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server to authenticate managers on its AOS-CX switches. The company wants CPPM to control which commands managers are allowed to enter.

  Which service must you add to the managers' TACACS+ enforcement profile?

  A. Cpass:HTTP
  B. Shell
  C. ARAP
  D. Aruba:Common
  B. Shell

  ---

  Explanation

  To control which commands managers are allowed to execute on AOS-CX switches using ClearPass Policy Manager (CPPM) as a TACACS+ server, you must configure the Shell service in the TACACS+ enforcement profile. The Shell

  service provides the ability to define granular access controls for commands. It supports policy-driven command authorization, which is essential in controlling administrative tasks based on roles.

• Question 8:

  A company has AOS-CX switches and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company wants switches to implement 802.1X authentication to CPPM and download user roles. What is one task that you must complete on CPPM to support this use case?

  A. Export roles on CPPM to a file that uses XML format.
  B. Create an admin account for the switch on CPPM with the HPE Aruba Networking User Role Download privilege level.
  C. Configure RADIUS enforcement profiles that specify the HPE-User-Role VSA.
  D. Upload the switch TPM certificate as a trusted CA certificate with the Others usage.
  C. Configure RADIUS enforcement profiles that specify the HPE-User-Role VSA.

  ---

  Explanation

  802.1X and User Role Download:

  AOS-CX switches use RADIUS attributes to dynamically download user roles from CPPM.

  The HPE-User-Role VSA (Vendor-Specific Attribute) must be configured in the RADIUS enforcement profiles to specify which role the switch should apply.

  Option Analysis:

  Option A: Incorrect. Exporting roles in XML is not needed for dynamic role download.

  Option B: Incorrect. Switches authenticate via RADIUS, not admin accounts with specific privileges.

  Option C: Correct. RADIUS enforcement profiles must include the HPE-User-Role VSA to implement user role download.

  Option D: Incorrect. TPM certificates are unrelated to RADIUS-based user role downloads.

• Question 9:

  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?

  A. Application
  B. Tips
  C. Device
  D. Endpoint
  D. Endpoint

  ---

  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.

• Question 10:

  Refer to Exhibit.

  

  A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application). In the CPDI interface, you go to the Generic Devices page and see the view shown in the exhibit. What correctly describes what you see?

  A. Each cluster is a group of unclassified devices that CPDI's machine learning has discovered to have similar attributes.
  B. Each cluster is a group of devices that match one of the tags configured by admins.
  C. Each cluster is all the devices that have been assigned to the same category by one of CPDI's built-in system rules.
  D. Each cluster is a group of devices that have been classified with user rules, but for which CPDI offers different recommendations.
  A. Each cluster is a group of unclassified devices that CPDI's machine learning has discovered to have similar attributes.

  ---

  Explanation

  In HPE Aruba Networking ClearPass Device Insight (CPDI), the clusters shown in the exhibit represent groups of unclassified devices that CPDI's machine learning algorithms have identified as having similar attributes. These clusters are

  formed based on observed characteristics and behaviors of the devices, helping administrators to categorize and manage devices more effectively.

  1.Machine Learning: CPDI uses machine learning to analyze device attributes and group them into clusters based on similarities.

  2.Unclassified Devices: These clusters typically represent devices that have not yet been explicitly classified by admins but share common attributes that suggest they belong to the same category.

  3.Management: This clustering helps in simplifying the process of managing and applying policies to groups of similar devices.
