  Explanation

  Wireshark: Follow TCP Stream:

  Wireshark provides an intuitive feature to filter and display a complete TCP conversation.

  By right-clicking any packet within the conversation and selecting "Follow # TCP Stream" , Wireshark isolates and displays the entire conversation.

  This feature allows you to view the communication in a simplified, sequential manner, including requests and responses.

  Option Analysis:

  Option A: Incorrect. Capture filters only apply during packet capturing, not for analyzing already saved packet captures.

  Option B: Incorrect. Sorting packets helps with organizing data but does not isolate a complete conversation.

  Option C: Incorrect. A capture filter for TCP port 5448 would have to be applied before capturing; it does not work for saved data.

  Option D: Correct. Right-clicking a packet and choosing

  "Follow TCP Stream" is the simplest

  way to display the full conversation between 10.1.70.90 and 10.1.79.11 on port 5448.

  Steps in Wireshark to Follow a TCP Stream:

  Locate any packet within the desired conversation (e.g., between 10.1.70.90 and 10.1.79.11 on TCP port 5448).

  Right-click on the packet.

  Choose

  "Follow" # "TCP Stream" .

  Wireshark will display the entire TCP conversation, including both directions of communication.

• Question 2:

  A company has HPE Aruba Networking APs running AOS-10 that connect to AOS-CX switches. The APs will:

  Authenticate as 802.1X supplicants to HPE Aruba Networking ClearPass Policy Manager (CPPM)

  Be assigned to the "APs" role on the switches

  Have their traffic forwarded locally.

  What information do you need to help you determine the VLAN settings for the "APs" role?

  A. Whether the switches are using local user-roles (LURs) or downloadable user-roles (DURs).
  B. Whether the APs bridge or tunnel traffic on their SSIDs.
  C. Whether the switches have established tunnels with an HPE Aruba Networking gateway.
  D. Whether the APs have static or DHCP-assigned IP addresses.
  B. Whether the APs bridge or tunnel traffic on their SSIDs.

  explanation:

  Explanation

  Traffic Forwarding for APs:

  In AOS-10, AP traffic forwarding can happen

  tunnels

  The VLAN settings on the "APs" role depend on whether the APs bridge the SSID traffic locally or forward it through a tunnel.

  Option B: Correct. You need to know whether the traffic is bridged or tunneled to determine the VLAN assignments.

  Option A: Incorrect. LURs/DURs affect role assignment but not VLAN settings for traffic forwarding.

  Option C: Incorrect. Establishing tunnels with gateways is relevant to centralized traffic forwarding, not VLANs for bridged traffic.

  Option D: Incorrect. AP IP addressing (static or DHCP) does not impact the VLAN for forwarded SSID traffic.

• Question 3:

  A company assigns a different block of VLAN IDs to each of its access layer AOS-CX switches. The switches run version 10.07. The IDs are used for standard purposes, such as for employees, VolP phones, and cameras. The company wants to apply 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM) and then steer clients to the correct VLANs for local forwarding.

  What can you do to simplify setting up this solution?

  A. Assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference names.
  B. Use the trunk allowed VLAN setting to assign multiple VLAN IDs to the same role.
  C. Change the VLAN IDs across the AOS-CX switches so that they are consistent.
  D. Avoid configuring the VLAN in the role; use trunk VLANs to assign multiple VLANs to the port instead.
  A. Assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference names.

  ---

  explanation:

  Explanation

  To simplify the setup of 802.1X authentication with HPE Aruba Networking ClearPass Policy Manager (CPPM) and ensure clients are steered to the correct VLANs for local forwarding, you should assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference these names. This approach allows for a more straightforward configuration and management process, as the user roles can apply consistent policies based on VLAN names rather than specific IDs. It also helps in maintaining clarity and reducing errors in VLAN assignments across different switches.

• Question 4:

  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?

  A. Go to the client's AP in HPE Aruba Networking Central. Use the "Security" page to run a packet capture.
  B. Access the CLI for the client's AP. Set up a mirroring session between its radio and a management station running Wireshark.
  C. 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.
  D. Go to that client in HPE Aruba Networking Central. Use the "Live Events" page to run a packet capture.

  explanation:

  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

• Question 5:

  A company issues user certificates to domain computers using its Windows CA and the default user certificate template. You have set up HPE Aruba Networking ClearPass Policy Manager (CPPM) to authenticate 802.1X clients with those certificates. However, during tests, you receive an error that authorization has failed because the usernames do not exist in the authentication source.

  What is one way to fix this issue and enable clients to successfully authenticate with certificates?

  A. Configure rules to strip the domain name from the username.
  B. Change the authentication method list to include both PEAP MSCHAPv2 and EAP-TLS.
  C. Add the ClearPass Onboard local repository to the authentication source list.
  D. Remove EAP-TLS from the authentication method list and add TEAP there instead.
  A. Configure rules to strip the domain name from the username.

  ---

  explanation:

  Explanation

  To fix the issue where authorization fails because the usernames do not exist in the authentication source, you can configure rules in HPE Aruba Networking ClearPass Policy Manager (CPPM) to strip the domain name from the username. When certificates are issued by a Windows CA, the username in the certificate often includes the domain (e.g., user@domain.com). ClearPass might not be able to find this format in the authentication source. By stripping the domain name, you ensure that ClearPass searches for just the username (e.g., user) in the authentication source, allowing successful authentication.

• Question 6:

  What is one use case for implementing user-based tunneling (UBT) on AOS-CX switches?

  A. Centralizing the distribution of wired traffic without requiring HPE Aruba Networking gateways
  B. Tunneling traffic directly to a third-party firewall in a client data center
  C. Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
  D. Applying enhanced security features such as deep packet inspection (DPI) to wired traffic
  D. Applying enhanced security features such as deep packet inspection (DPI) to wired traffic

  ---

  explanation:

  Explanation

  Implementing user-based tunneling (UBT) on AOS-CX switches is beneficial for applying enhanced security features such as deep packet inspection (DPI) to wired traffic. UBT allows the traffic from specific users or devices to be tunneled to a central controller or security appliance where advanced security policies, including DPI, can be applied. This approach ensures that even wired traffic benefits from the same level of security and inspection typically available for wireless traffic, thus enhancing overall network security.

• Question 7:

  HPE Aruba Networking ClearPass Policy Manager (CPPM) uses a service to authenticate clients. You are now adding the Endpoints Repository as an authorization source for the service, and you want to add rules to the service's policies that

  apply different access levels based, in part, on a client's device category.

  You need to ensure that CPPM can apply the new correct access level after discovering new clients' categories.

  What should you enable on the service?

  A. The Posture Compliance option in the Service tab
  B. The Profile Endpoints option in the Service tab
  C. The Use cached Roles and Posture attributes from previous sessions option in the Enforcement tab
  D. The Audit End-host option in the Service tab
  B. The Profile Endpoints option in the Service tab

  ---

  explanation:

  Explanation

  To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) can apply the correct access levels based on a client's device category after discovering new clients, you need to enable the "Profile Endpoints" option in the Service tab. This option allows CPPM to profile and categorize endpoints dynamically, ensuring that the appropriate access levels are applied based on the device's characteristics. Enabling this feature ensures that new devices are accurately profiled and that access policies can be enforced based on the updated device information.

• Question 8:

  A company has a variety of HPE Aruba Networking solutions, including an HPE Aruba Networking infrastructure and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company passes traffic from the corporate LAN destined to the data center through a third-party SRX firewall. The company would like to further protect itself from internal threats.

  What is one solution that you can recommend?

  A. Have the third-party firewall send Syslogs to CPPM, which can work with network devices to lock internal attackers out of the network.
  B. Use tunnel mode SSIDs and user-based tunneling (UBT) on AOS-CX switches to pass all internal traffic directly through the third-party firewall.
  C. Add ClearPass Device Insight (CPDI) to the solution; integrate it with the third-party firewall to develop more complete device profiles.
  D. Configure CPPM to poll the third-party firewall for a broad array of information about internal clients, such as profile and posture.
  A. Have the third-party firewall send Syslogs to CPPM, which can work with network devices to lock internal attackers out of the network.

  ---

  explanation:

  Explanation

  To further protect the company from internal threats, you can recommend having the third-party SRX firewall send Syslogs to HPE Aruba Networking ClearPass Policy Manager (CPPM). ClearPass can analyze these logs to detect potential security incidents and coordinate with network devices to respond to threats. By integrating Syslog data from the firewall, CPPM can identify malicious activities and take actions such as locking internal attackers out of the network or triggering specific security policies. This approach enhances the company's internal threat detection and response capabilities.

• Question 9:

  A company has HPE Aruba Networking infrastructure devices. The devices authenticate clients to HPE Aruba Networking ClearPass Policy Manager (CPPM). You want CPPM to track information about clients, such as their IP addresses and their network bandwidth utilization. What should you set up on the network infrastructure devices to help that happen?

  A. Logging with CPPM configured as a Syslog server.
  B. Dynamic authorization enabled in the RADIUS settings for CPPM.
  C. RADIUS accounting to CPPM, including interim updates.
  D. An IF-MAP interface with CPPM as the destination.
  C. RADIUS accounting to CPPM, including interim updates.

  ---

  explanation:

  Explanation

  RADIUS Accounting:

  RADIUS accounting enables network devices to report client session details (e.g., IP addresses,session duration, bandwidth usage) to CPPM.

  Interim updates ensure CPPM receives ongoing updates about the client's session, enabling accurate tracking.

  Option Analysis:

  Option A: Incorrect. Syslog logging sends general system logs, not client session details.

  Option B: Incorrect. Dynamic authorization (CoA) handles session changes but does not provide usage tracking.

  Option C: Correct. RADIUS accounting with interim updates tracks client IP addresses and bandwidth utilization.

  Option D: Incorrect. IF-MAP interfaces are used for metadata sharing, not for RADIUS-based tracking.

• Question 10:

  Refer to the exhibit:

  

  The exhibit shows the TACACS+ enforcement profile that HPE Aruba Networking ClearPass Policy Manager (CPPM) assigns to a manager. When this manager logs into an AOS-CX switch, what does the switch do?

  A. Assigns the manager operator-level privileges
  B. Assigns the manager administrator-level privileges
  C. Rejects the manager with an error message
  D. Assigns the manager auditor-level privileges
  A. Assigns the manager operator-level privileges

  ---

  explanation:

  Explanation

  TACACS+ Enforcement Profile:

  The profile specifies a Service Attribute under Aruba:Common with:

  Name: Aruba-Admin-Role

  Value: operators

  AOS-CX Role Mapping:

  On Aruba AOS-CX switches, the Aruba-Admin-Role attribute maps the authenticated user to predefined roles:

  operators: Operator-level privileges (read-only access, limited commands).

  administrators: Full administrator privileges.

  Other roles like auditors may exist based on configuration.

  Analysis:

  The value operators explicitly maps the user to operator-level privileges , granting read-only access to the AOS-CX switch.

  Since the Aruba-Admin-Role is correctly set and recognized, the switch assigns the appropriate role without errors.

  Option Breakdown:

  Option A: Correct. The switch assigns operator-level privileges based on the Aruba-Admin- Role value.

  Option B: Incorrect. Administrator-level privileges require the role value to be administrators.

  Option C: Incorrect. The manager is successfully authenticated and authorized; there is no error.

  Option D: Incorrect. There is no reference to an auditor role in the configuration shown.

  Conclusion:

  The operators value in the TACACS+ enforcement profile ensures that the manager is assigned operator- level privileges on the AOS-CX switch.
