HP Aruba Certified Network Security Associate Exam Sample Questions (Q111-Q116):

NEW QUESTION # 111
Which endpoint classification capabilities do Aruba network infrastructure devices have on their own without ClearPass solutions?

  • A. ArubaOS-CX switches can use a combination of active and passive methods to assign roles to clients.
  • B. ArubaOS devices (controllers and lAPs) can use DHCP fingerprints to assign roles to clients.
  • C. ArubaOS devices can use a combination of DHCP fingerprints, HTTP User-Agent strings, and Nmap to construct endpoint profiles.
  • D. ArubaOS-Switches can use DHCP fingerprints to construct detailed endpoint profiles.

Answer: B

Explanation:
Without the integration of Aruba ClearPass or other advanced network access control solutions, ArubaOS devices (controllers and Instant APs) are able to use DHCP fingerprinting to assign roles to clients. This method allows the devices to identify the type of client devices connecting to the network based on the DHCP requests they send. While this is a more basic form of endpoint classification compared to the capabilities provided by ClearPass, it still enables some level of access control based on device type. This functionality and its limitations are described in Aruba's product documentation for ArubaOS devices, highlighting the benefits of integrating a full-featured solution like ClearPass for more granular and powerful endpoint classification capabilities.


NEW QUESTION # 112
A company has an AOS controller-based solution with a WPA3-Enterprise WLAN, which authenticates wireless clients to HPE Aruba Networking ClearPass Policy Manager (CPPM). The company has decided to use digital certificates for authentication. A user's Windows domain computer has had certificates installed on it. However, the Networks and Connections window shows that authentication has failed for the user. The Mobility Controller's (MC's) RADIUS events show that it is receiving Access-Rejects for the authentication attempt.
What is one place that you can look for deeper insight into why this authentication attempt is failing?

  • A. The RADIUS events within the CPPM Event Viewer
  • B. The Alerts tab in the authentication record in CPPM Access Tracker
  • C. The reports generated by HPE Aruba Networking ClearPass Insight
  • D. The packets captured on the MC control plane destined to UDP 1812

Answer: B

Explanation:
The scenario involves an AOS-8 controller-based solution with a WPA3-Enterprise WLAN using HPE Aruba Networking ClearPass Policy Manager (CPPM) for authentication. The company is using digital certificates for authentication (likely EAP-TLS, as it's the most common certificate-based method for WPA3-Enterprise). A user's Windows domain computer has certificates installed, but authentication fails. The Mobility Controller (MC) logs show Access-Rejects from CPPM, indicating that CPPM rejected the authentication attempt.
Access-Reject: An Access-Reject message from CPPM means that the authentication failed due to a policy violation, certificate issue, or other configuration mismatch. To troubleshoot, we need to find detailed information about why CPPM rejected the request.
Option C, "The Alerts tab in the authentication record in CPPM Access Tracker," is correct. Access Tracker in CPPM logs all authentication attempts, including successful and failed ones. For a failed attempt (Access-Reject), the authentication record in Access Tracker will include an Alerts tab that provides detailed reasons for the failure. For example, if the client's certificate is invalid (e.g., expired, not trusted, or missing a required attribute), or if the user does not match a policy in CPPM, the Alerts tab will specify the exact issue (e.g., "Certificate not trusted," "User not found in directory").
Option A, "The reports generated by HPE Aruba Networking ClearPass Insight," is incorrect. ClearPass Insight is used for generating reports and analytics (e.g., trends, usage patterns), not for real-time troubleshooting of specific authentication failures.
Option B, "The RADIUS events within the CPPM Event Viewer," is incorrect. The Event Viewer logs system-level events (e.g., service crashes, NAD mismatches), not detailed authentication failure reasons. While it might log that an Access-Reject was sent, it won't provide the specific reason for the rejection.
Option D, "The packets captured on the MC control plane destined to UDP 1812," is incorrect. Capturing packets on the MC control plane for UDP 1812 (RADIUS authentication port) can show the RADIUS exchange, but it won't provide the detailed reason for the Access-Reject. The MC logs already show the Access-Reject, so the issue lies on the CPPM side, and Access Tracker provides more insight.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"Access Tracker (Monitoring > Live Monitoring > Access Tracker) logs all authentication attempts, including failed ones. For an Access-Reject, the authentication record in Access Tracker includes an Alerts tab that provides detailed reasons for the failure. For example, in a certificate-based authentication (e.g., EAP-TLS), the Alerts tab might show 'Certificate not trusted' if the client's certificate is not trusted by ClearPass, or 'User not found' if the user does not match a policy. This is the primary place to look for deeper insight into authentication failures." (Page 299, Access Tracker Troubleshooting Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
"If the Mobility Controller logs show an Access-Reject from the RADIUS server (e.g., ClearPass), check the RADIUS server's authentication logs for details. In ClearPass, the Access Tracker provides detailed failure reasons in the Alerts tab of the authentication record, such as certificate issues or policy mismatches."

NEW QUESTION # 113
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?

  • A. WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses
    802.1X authentication.
  • B. WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.
  • C. WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.
  • D. WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.

Answer: B

Explanation:
WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.


NEW QUESTION # 114
A company has a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise security, supported by an Aruba Mobility Controller (MC) and campus APs (CAPs). You have been asked to capture packets from a wireless client connected to this WLAN and submit the packets to the security team.
What is a guideline for this capture?

  • A. You should capture the traffic on the AP, so that the capture is as close to the source as possible.
  • B. You should mirror traffic from the switch port that connects to the AP out on a port connected to a packet analyzer.
  • C. You should capture the traffic on the MC dataplane to obtain unencrypted traffic.
  • D. You should use an Air Monitor (AM) to capture the packets in the air.

Answer: D

Explanation:
The correct approach for capturing packets from a wireless client in a WLAN that uses Tunnel forwarding mode and WPA3-Enterprise, managed by an Aruba Mobility Controller and Campus APs, is to use an Air Monitor (AM). An AM is specifically designed to capture wireless traffic "in the air," which means it listens to the wireless signals transmitted between devices and the access points. This method ensures that the capture includes all the necessary details while maintaining the integrity and security of the data as it is transmitted over the air. Using an Air Monitor helps in analyzing the raw wireless traffic before it gets encrypted or tunneled to the Mobility Controller, providing a clear view of the wireless client's activity and interactions. The information regarding the use of Air Monitors for packet capture in such environments can be found in the Aruba Network's official documentation and configuration guides for WLAN setups and security analysis.


NEW QUESTION # 115
You need to deploy an Aruba instant AP where users can physically reach It. What are two recommended options for enhancing security for management access to the AP? (Select two )

  • A. Place a Tamper Evident Label (TELS) over its console port
  • B. Disable the Web Ul.
  • C. install a CA-signed certificate
  • D. Configure WPA3-Enterpnse security on the AP
  • E. Disable Its console ports

Answer: B,C

Explanation:
When deploying an Aruba Instant AP in a location where users can physically access it, enhancing security for management access could involve several measures: C. Disabling the Web UI will prevent unauthorized access via the browser-based management interface, which could be a security risk if the AP is within physical reach of untrusted parties. E. Installing a CA-signed certificate helps ensure that any communication with the AP's management interface is encrypted and authenticated, preventing man-in-the-middle attacks and eavesdropping.
