HP Aruba Certified Network Security Professional Exam Sample Questions (Q60-Q65):

NEW QUESTION # 60
Admins have recently turned on Wireless IDS/IPS infrastructure detection at the high level on HPE Aruba Networking APs. When you check WIDS events, you see several RTS rate and CTS rate anomalies, which were triggered by neighboring APs.
What can you interpret from this event?

A. These neighboring APs might be hackers trying to launch a DoS, but are more likely operating normally; you should start by tuning the event thresholds.
B. These neighboring APs are likely to be wireless clients that are inappropriately bridging their wired and wireless NICs; you should track down and remove them.
C. These neighboring APs are actually rogue APs, and you should enable wireless tarpit containment on them.
D. These neighboring APs are actually rogue APs, and you should enable wireless de-authentication containment on them.

Answer: A

Explanation:
When Wireless IDS/IPS infrastructure detection reports RTS (Request to Send) and CTS (Clear to Send) rate anomalies triggered by neighboring APs, it is often an indication of unusual, but not necessarily malicious, behavior. These anomalies can be caused by neighboring APs operating normally but under specific conditions that trigger the alerts. Before assuming a security threat, it is recommended to tune the event thresholds to better match the environment and reduce false positives. This approach helps to distinguish between normal operations and potential DoS attacks.
Reference: Aruba's Wireless IDS/IPS configuration guides provide information on interpreting events, adjusting thresholds, and distinguishing between legitimate and malicious activities in a wireless network environment.

NEW QUESTION # 61

The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?

A. Clear the check box for using simple certificate selection and select the desired certificate manually.
B. Specify at least two server names under the " Connect to these servers " field.
C. Select the desired Trusted Root Certificate Authority and select the check box next to " Don ' t prompt users. "
D. Under the " Connect to these servers " field, use a wildcard in the server name.

Answer: B

Explanation:
To follow best security practices for 802.1X authentication settings in Windows domain clients:
Specify at least two server names under " Connect to these servers " :
Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
Select the desired Trusted Root Certificate Authority and " Don ' t prompt users " :
Select the Trusted Root CA that issued the RADIUS server ' s certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
Enabling " Don ' t prompt users " ensures end users are not confused or tricked into accepting certificates from untrusted servers.
Why the other options are incorrect:
Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
Option D: Incorrect. Clearing " Use simple certificate selection " requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
Server Validation: Specify the exact RADIUS server names in the " Connect to these servers " field.
Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
User Prompts: Enable " Don ' t prompt users " to enforce automatic and secure authentication without user intervention.

NEW QUESTION # 62
Refer to the exhibit.

The exhibit shows a saved packet capture, which you have opened in Wireshark. You want to focus on the complete conversation between 10.1.70.90 and 10.1.79.11 that uses source port 5448.
What is a simple way to do this in Wireshark?

A. Apply a capture filter that selects for both the 10.1.70.90 and 10.1.79.11 IP addresses.
B. Click the Source column and then the Destination column to sort the packets into the desired order.
C. Apply a capture filter that selects for TCP port 5448.
D. Right-click one of the packets between those addresses and choose to follow the stream.

Answer: D

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.
This feature is especially useful when troubleshooting or analyzing detailed interactions between hosts.

NEW QUESTION # 63
What can help justify the extra cost of air monitors (AMs) to a company?

A. AMs support additional IDS/IPS features, such as malware and Trojan detection, to enhance overall security.
B. AMs support tarpit containment, which introduces fewer legal issues than deauthentication containment.
C. AMs can support wireless clients when they are not actively containing a device, so companies benefit from better security and connectivity.
D. AMs can detect wireless threats much faster than hybrid APs, reducing the company's vulnerability surface.

Answer: D

Explanation:
Dedicated air monitors are justified when a company wants faster and more complete wireless threat detection. Hybrid APs must divide radio time between serving clients and scanning the RF environment.
Dedicated AMs focus on monitoring, which allows them to detect rogue APs, evil-twin behavior, unauthorized SSID use, ad hoc networks, and other wireless threats more quickly. Faster detection reduces the time an attacker can operate unnoticed and lowers wireless exposure. AMs do not provide endpoint malware or Trojan detection in the same way an endpoint or gateway security engine does. They also do not serve wireless clients while operating as dedicated monitors. The clearest security justification is faster wireless threat detection compared with hybrid scanning.

NEW QUESTION # 64
Refer to Exhibit.

A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application). In the CPDI interface, you go to the Generic Devices page and see the view shown in the exhibit.
What correctly describes what you see?

A. Each cluster is a group of unclassified devices that CPDI ' s machine learning has discovered to have similar attributes.
B. Each cluster is a group of devices that match one of the tags configured by admins.
C. Each cluster is a group of devices that have been classified with user rules, but for which CPDI offers different recommendations.
D. Each cluster is all the devices that have been assigned to the same category by one of CPDI ' s built-in system rules.

Answer: A

Explanation:
In HPE Aruba Networking ClearPass Device Insight (CPDI), the clusters shown in the exhibit represent groups of unclassified devices that CPDI ' s machine learning algorithms have identified as having similar attributes. These clusters are formed based on observed characteristics and behaviors of the devices, helping administrators to categorize and manage devices more effectively.
1.Machine Learning: CPDI uses machine learning to analyze device attributes and group them into clusters based on similarities.
2.Unclassified Devices: These clusters typically represent devices that have not yet been explicitly classified by admins but share common attributes that suggest they belong to the same category.
3.Management: This clustering helps in simplifying the process of managing and applying policies to groups of similar devices.
Reference: ClearPass Device Insight documentation on device clustering and machine learning provides detailed information on how devices are grouped into clusters based on observed attributes and behaviors.
