HP Aruba Certified Network Security Associate Exam Sample Questions (Q154-Q159):

NEW QUESTION # 154
What is a benefit of Opportunistic Wireless Encryption (OWE)?

  • A. It offers more control over who can connect to the wireless network when compared with WPA2-Personal
  • B. It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MUM) attacks
  • C. It allows both WPA2-capabie and WPA3-capable clients to authenticate to the same WPA-Personal WLAN
  • D. It allows anyone lo connect, but provides better protection against eavesdropping than a traditional open network

Answer: D

Explanation:
The benefit of Opportunistic Wireless Encryption (OWE) is that it allows anyone to connect, but it provides better protection against eavesdropping than a traditional open network. OWE is a type of wireless security specified in the WPA3 standard that offers encrypted communication without the complexity of a full authentication process, thereby securing data on networks that would otherwise be open and unencrypted.
:
Wi-Fi Alliance specifications for WPA3 and Opportunistic Wireless Encryption (OWE).
Security whitepapers and industry articles discussing the advantages of WPA3, including OWE.


NEW QUESTION # 155
You have been authorized to use containment to respond to rogue APs detected by ArubaOS Wireless Intrusion Prevention (WIP). What is a consideration for using tarpit containment versus traditional wireless containment?

  • A. Tarpit containment forms associations with clients to enable more effective containment with fewer disassociation frames than traditional wireless containment.
  • B. Rather than target all clients connected to rogue APs, tarpit containment targets only authorized clients that are connected to a rogue AP, reducing the chance of negative effects on neighbors.
  • C. Rather than function wirelessly, tarpit containment sends ARP frames over the wired network to poison rogue APs ARP tables and prevent them from transmitting on the wired network.
  • D. Tarpit containment does not require an RF Protect license to function, while traditional wireless containment does.

Answer: A

Explanation:
Tarpit containment is a method used in ArubaOS Wireless Intrusion Prevention (WIP) to contain rogue APs. It differs from traditional wireless containment in several ways, particularly in how it interacts with clients and manages network resources.
Tarpit containment works by spoofing frames from an AP to confuse a client about its association. It forces the client to associate with a fake channel or BSSID, which is more efficient than rogue containment via repeated de-authorization requests. This method is designed to be less disruptive and more resource-efficient1.
Here's why the other options are not correct:
Option A is incorrect because tarpit containment does not involve sending ARP frames over the wired network. It operates wirelessly by creating a fake channel or BSSID.
Option B is incorrect because tarpit containment does not selectively target authorized clients; it affects all clients connected to the rogue AP.
Option C is incorrect because tarpit containment does require an RF Protect license to function2.
Therefore, Option D is the correct answer. Tarpit containment is more effective at keeping clients off the network with fewer disassociation frames than traditional wireless containment. It achieves this by forming associations with clients, which leads to a more efficient use of airtime and reduces the chance of negative effects on legitimate network users12.


NEW QUESTION # 156
A company has an Aruba solution with a Mobility Master (MM) Mobility Controllers (MCs) and campus Aps. What is one benefit of adding Aruba Airwave from the perspective of forensics?

  • A. AirWave enables low level debugging on the devices across the ArubaOS solution
  • B. Airwave is required to activate Wireless Intrusion Prevention (WIP) services on the ArubaOS solution
  • C. Airwave retains information about the network for much longer periods than ArubaOS solution
  • D. Airwave can provide more advanced authentication and access control services for the AmbaOS solution

Answer: C

Explanation:
Adding Aruba Airwave to an Aruba solution that includes a Mobility Master (MM), Mobility Controllers (MCs), and campus APs offers several benefits, notably in the realm of network forensics. One of the significant advantages is that Airwave can retain detailed information about the network for much longer periods than what is typically possible with just ArubaOS solutions. This extensive data retention is crucial for forensic analysis, allowing network administrators and security professionals to conduct thorough investigations of past incidents. With access to historical data, professionals can identify trends, pinpoint security breaches, and understand the impact of specific changes or events within the network over time.
References:
Aruba's official product documentation and user guides for Airwave and ArubaOS, which outline features, benefits, and use cases related to network management and forensic capabilities.

NEW QUESTION # 157
How should admins deal with vulnerabilities that they find in their systems?

  • A. They should apply fixes, such as patches, to close the vulnerability before a hacker exploits it.
  • B. They should classify the vulnerability as malware. a DoS attack or a phishing attack.
  • C. They should notify the security team as soon as possible that the network has already been breached.
  • D. They should add the vulnerability to their Common Vulnerabilities and Exposures (CVE).

Answer: A

Explanation:
When vulnerabilities are identified in systems, it is crucial for administrators to act immediately to mitigate the risk of exploitation by attackers. The appropriate response involves applying fixes, such as software patches or configuration changes, to close the vulnerability. This proactive approach is necessary to protect the integrity, confidentiality, and availability of the system resources and data. It's important to prioritize these actions based on the severity and exploitability of the vulnerability to ensure that the most critical issues are addressed first.References:

NEW QUESTION # 158
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 EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
  • B. Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster
  • C. Whether the client has a valid certificate installed on it to let it support EAP-TLS
  • D. Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS

Answer: C

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."
