HP Aruba Certified Network Security Associate Exam Sample Questions (Q97-Q102):

NEW QUESTION # 97
What is one way a noneypot can be used to launch a man-in-the-middle (MITM) attack to wireless clients?

  • A. it examines wireless clients' probes and broadcasts the SSlDs in the probes, so that wireless clients will connect to it automatically.
  • B. it runs an NMap scan on the wireless client to And the clients MAC and IP address. The hacker then connects to another network and spoofs those addresses.
  • C. it uses a combination or software and hardware to jam the RF band and prevent the client from connecting to any wireless networks
  • D. it uses ARP poisoning to disconnect wireless clients from the legitimate wireless network and force clients to connect to the hacker's wireless network instead.

Answer: D


NEW QUESTION # 98

NEW QUESTION # 99
Refer to the exhibit.
A company has an HPE Aruba Networking Instant AP cluster. A Windows 10 client is attempting to connect to a WLAN that enforces WPA3-Enterprise with authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM is configured to require EAP-TLS. The client authentication fails. In the record for this client's authentication attempt on CPPM, you see this alert.
What is one thing that you check to resolve this issue?

  • A. Whether the client has a valid certificate installed on it to let it support EAP-TLS
  • B. Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
  • C. Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster
  • D. Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS

Answer: A

Explanation:
The scenario involves an HPE Aruba Networking Instant AP (IAP) cluster with a WLAN configured for WPA3-Enterprise security, using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the authentication server. CPPM is set to require EAP-TLS for authentication. A Windows 10 client attempts to connect but fails, and the CPPM Access Tracker shows an error: "Client does not support configured EAP methods," with the error code 9015 under the RADIUS protocol category.
EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) is a certificate-based authentication method that requires both the client (supplicant) and the server (CPPM) to present valid certificates during the authentication process. The error message indicates that the client does not support the EAP method configured on CPPM (EAP-TLS), meaning the client is either not configured to use EAP-TLS or lacks the necessary components to perform EAP-TLS authentication.
Option B, "Whether the client has a valid certificate installed on it to let it support EAP-TLS," is correct. EAP-TLS requires the client to have a valid client certificate issued by a trusted Certificate Authority (CA) that CPPM trusts. If the Windows 10 client does not have a client certificate installed, or if the certificate is invalid (e.g., expired, not trusted by CPPM, or missing), the client cannot negotiate EAP-TLS, resulting in the error seen in CPPM. This is a common issue in EAP-TLS deployments, and checking the client's certificate is a critical troubleshooting step.
Option A, "Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster," is incorrect because the error indicates that CPPM received the authentication request and rejected it due to the client's inability to support EAP-TLS. This suggests that the IAP cluster is correctly configured to use EAP-TLS (as the request reached CPPM with EAP-TLS as the method). The AAA profile on the IAP cluster is likely already set to use EAP-TLS, or the error would be different (e.g., a connectivity or configuration mismatch issue).
Option C, "Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster," is incorrect for a similar reason. The SSID profile on the IAP cluster defines the security settings (e.g., WPA3-Enterprise), and the AAA profile specifies the EAP method. Since the authentication request reached CPPM with EAP-TLS, the IAP cluster is correctly configured to use EAP-TLS.
Option D, "Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS," is incorrect because Windows 10 natively supports EAP-TLS. The built-in Windows 10 802.1X supplicant (Windows WLAN AutoConfig service) supports EAP-TLS, provided a valid client certificate is installed. A third-party supplicant is not required.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"EAP-TLS requires both the client and the server to present a valid certificate during the authentication process. If the client does not have a valid certificate installed, or if the certificate is not trusted by ClearPass (e.g., the issuing CA is not in the ClearPass trust list), the authentication will fail with an error such as 'Client does not support configured EAP methods' (Error Code 9015). To resolve this, ensure that the client has a valid certificate installed and that the certificate's issuing CA is trusted by ClearPass." (Page 295, EAP-TLS Troubleshooting Section) Additionally, the HPE Aruba Networking Instant 8.11 User Guide notes:
"For WPA3-Enterprise with EAP-TLS, the client must have a valid client certificate installed to authenticate successfully. If the client lacks a certificate or the certificate is invalid, the authentication will fail, and ClearPass will log an error indicating that the client does not support the configured EAP method."

NEW QUESTION # 100
An ArubaOS-CX switch enforces 802.1X on a port. No fan-through options or port-access roles are configured on the port The 802 1X supplicant on a connected client has not yet completed authentication Which type of traffic does the authenticator accept from the client?

  • A. EAP only
  • B. DHCP, DNS and RADIUS only
  • C. RADIUS only
  • D. DHCP, DNS, and EAP only

Answer: A

Explanation:
For an ArubaOS-CX switch enforcing 802.1X on a port without any fallback options or port-access roles configured, and where the supplicant on the connected client has not completed authentication, the only type of traffic the authenticator accepts from the client is EAP (Extensible Authentication Protocol). EAP is a universal authentication framework used in 802.1X for message exchange during the authentication process.
The switch allows EAP packets because they are necessary for the client and the authentication server to perform the authentication process. This is standard behavior for 802.1X authenticators, which is to permit EAP traffic to pass through even before authentication is successful to facilitate the authentication exchange.
This information is supported by the IEEE 802.1X standard and ArubaOS-CX security configuration guides.


NEW QUESTION # 101
Your Aruba Mobility Master-based solution has detected a rogue AP Among other information the ArubaOS Detected Radios page lists this Information for the AP SSID = PubllcWiFI BSSID = a8M27 12 34:56 Match method = Exact match Match type = Eth-GW-wired-Mac-Table The security team asks you to explain why this AP is classified as a rogue. What should you explain?

  • A. The AP Is connected to your LAN because It is transmitting wireless traffic with your network's default gateway's MAC address as a source MAC Because it does not belong to the company, it is a rogue
  • B. The AP has been detected as launching a DoS attack against your company's default gateway. This qualities it as a rogue which needs to be contained with wireless association frames immediately
  • C. The ap has a BSSID mat matches authorized client MAC addresses. This indicates that the AP is spoofing the MAC address to gam unauthorized access to your company's wireless services, so It is a rogue
  • D. The AP is spoofing a routers MAC address as its BSSID. This indicates mat, even though WIP cannot determine whether the AP is connected to your LAN. it is a rogue.

Answer: A

Explanation:
The AP is classified as a rogue because it is connected to your LAN and is transmitting wireless traffic with your network's default gateway's MAC address as a source MAC. In this scenario, the 'Match method = Exact match' and 'Match type = Eth-GW-wired-Mac-Table' indicates that the rogue AP has been detected by matching the Ethernet gateway's MAC address, which is on the wired network, implying that the rogue AP is connected to the corporate LAN. Since the AP does not belong to the company, its presence on the network is unauthorized and is thus classified as a rogue AP.

Wireless security best practices that explain how the presence of unauthorized APs on the LAN constitutes a security threat.
