HP Aruba Certified Network Security Associate Exam Sample Questions (Q71-Q76):NEW QUESTION # 71
What is the purpose of an Enrollment over Secure Transport (EST) server?
  • A. It provides a more secure alternative to private CAs at less cost than a public CA.
  • B. It helps admins to avoid expired certificates with less management effort.
  • C. It acts as an intermediate Certification Authority (CA) that signs end-entity certificates.
  • D. It provides a secure central repository for private keys associated with devices' digital certif-icates.
Answer: B

NEW QUESTION # 72
You have detected a Rogue AP using the Security Dashboard Which two actions should you take in responding to this event? (Select two)
  • A. There is no need to locate the AP If the Aruba solution is properly configured to automatically contain it.
  • B. For forensic purposes, you should copy out logs with relevant information, such as the time mat the AP was detected and the AP's MAC address.
  • C. This is a serious security event, so you should always contain the AP immediately regardless of your company's specific policies.
  • D. You should receive permission before containing an AP. as this action could have legal Implications.
  • E. There is no need to locale the AP If you manually contain It.
Answer: B,D
Explanation:
When responding to the detection of a Rogue AP, it's important to consider legal implications and to gather forensic evidence:
You should receive permission before containing an AP (Option C), as containing it could disrupt service and may have legal implications, especially if the AP is on a network that the organization does not own.
For forensic purposes, it is essential to document the event by copying out logs with relevant information, such as the time the AP was detected and the AP's MAC address (Option D). This information could be crucial if legal action is taken or if a detailed analysis of the security breach is required.
Automatically containing an AP without consideration for the context (Options A and E) can be problematic, as it might inadvertently interfere with neighboring networks and cause legal issues. Immediate containment without consideration of company policy (Option B) could also violate established incident response procedures.

Industry guidelines on responsible handling of rogue access point detections, including legal considerations and incident documentation.

NEW QUESTION # 73
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?
  • A. WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.
  • B. WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.
  • C. WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.
  • D. WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses 802.1X authentication.
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 # 74
What is a benefit of Opportunistic Wireless Encryption (OWE)?
  • A. It provides protection for wireless clients against both honeypot APs and man-in-the-middle (MUM) attacks
  • B. It allows anyone lo connect, but provides better protection against eavesdropping than a traditional open network
  • C. It allows both WPA2-capabie and WPA3-capable clients to authenticate to the same WPA-Personal WLAN
  • D. It offers more control over who can connect to the wireless network when compared with WPA2-Personal
Answer: B
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.

NEW QUESTION # 75
Which correctly describes one of HPE Aruba Networking ClearPass Policy Manager's (CPPM's) device profiling methods?
  • A. CPPM can use Wireshark to actively probe devices, analyze their traffic patterns, and construct an endpoint profile.
  • B. CPPM can analyze settings such as TCP/UDP ports used for HTTP, DHCP, and DNS in endpoints' traffic to fingerprint the OS.
  • C. CPPM can analyze settings such as TTL and time window size in endpoints' TCP traffic in order to fingerprint the OS.
  • D. CPPM can use SNMP to configure Aruba switches and mobility devices to mirror client traffic to CPPM for analysis.
Answer: C
Explanation:
HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to identify and classify endpoints on the network, enabling granular access control based on device type, OS, or other attributes. CPPM supports both passive and active profiling methods.
Option C, "CPPM can analyze settings such as TTL and time window size in endpoints' TCP traffic in order to fingerprint the OS," is correct. TCP fingerprinting is a passive profiling method used by CPPM. It involves analyzing TCP packet headers, such as the Time To Live (TTL) value and TCP window size, which vary between operating systems (e.g., Windows, Linux, macOS). CPPM captures this traffic (e.g., via mirrored traffic from a switch or controller) and matches the TCP attributes against its fingerprint database to identify the OS of the endpoint.
Option A, "CPPM can use Wireshark to actively probe devices, analyze their traffic patterns, and construct an endpoint profile," is incorrect. CPPM does not use Wireshark for profiling; Wireshark is a third-party packet analysis tool. CPPM has its own built-in profiling engine and does not rely on external tools like Wireshark for active probing.
Option B, "CPPM can use SNMP to configure Aruba switches and mobility devices to mirror client traffic to CPPM for analysis," is incorrect. While CPPM can receive mirrored traffic for profiling (e.g., via SPAN or mirror ports), it does not use SNMP to configure the mirroring. The configuration of traffic mirroring is typically done manually on the switch or controller (e.g., using a datapath mirror on an MC), not via SNMP by CPPM.
Option D, "CPPM can analyze settings such as TCP/UDP ports used for HTTP, DHCP, and DNS in endpoints' traffic to fingerprint the OS," is incorrect. While CPPM does analyze HTTP, DHCP, and DNS traffic for profiling, it does not fingerprint the OS based on TCP/UDP ports. Instead, it uses attributes like DHCP Option 55 (for DHCP fingerprinting) or HTTP User-Agent strings (for HTTP fingerprinting) to identify devices, not the ports themselves.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"ClearPass supports TCP fingerprinting as a passive profiling method to identify the operating system of endpoints. By analyzing TCP packet headers, such as the Time To Live (TTL) value and TCP window size, ClearPass can fingerprint the OS of a device. For example, Windows devices typically have a TTL of 128, while Linux devices often have a TTL of 64. These attributes are matched against ClearPass's fingerprint database to classify the device." (Page 248, TCP Fingerprinting Section) Additionally, the ClearPass Device Insight Data Sheet notes:
"ClearPass uses passive profiling techniques like TCP fingerprinting to identify device operating systems. By examining TCP attributes such as TTL and window size, ClearPass can accurately determine whether a device is running Windows, Linux, macOS, or another OS, enabling precise policy enforcement." (Page 3, Profiling Methods Section)
