NEW QUESTION # 107
A company has Aruba APs that are controlled by Central and that implement WIDS. When you check WIDS events, you see a " detect valid SSID misuse " event. What can you interpret from this event, and what steps should you take?
Answer: C
Explanation:
The " Detect Valid SSID Misuse " event in Aruba ' s Wireless Intrusion Detection System (WIDS) indicates that a valid SSID, associated with your network, is being broadcast from an unauthorized source. This scenario often signals a potential rogue access point attempting to deceive clients into connecting to it (e.g., for credential harvesting or man-in-the-middle attacks).
1. Explanation of Each Option
A). Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat:
Incorrect:
This event is not related to authentication failures by legitimate clients.
Misconfigured authentication settings would lead to events like " authentication failures " or " radius issues, " not " valid SSID misuse. " B). Admins have likely misconfigured SSID security settings on some of the company ' s APs. You should have them check those settings:
Incorrect:
This event refers to an external device broadcasting your SSID, not misconfiguration on the company's authorized APs.
WIDS differentiates between valid corporate APs and rogue APs.
C). Hackers are likely trying to pose as authorized APs. You should use the detecting radio information and immediately track down the device that triggered the event:
Correct:
This is the most likely cause of the " detect valid SSID misuse " event. A rogue AP broadcasting a corporate SSID could lure clients into connecting to it, exposing sensitive credentials or traffic.
Immediate action includes:
Using the radio information from the event logs to identify the rogue AP ' s location.
Physically locating and removing the rogue device.
Strengthening WIPS/WIDS policies to prevent further misuse.
D). This event might be a threat but is almost always a false positive. You should wait to see the event over several days before following up on it:
Incorrect:
While false positives are possible, " valid SSID misuse " is a critical security event that should not be ignored.
Delaying action increases the risk of successful attacks against your network.
2. Recommended Steps to Address the Event
Review Event Logs:
Gather details about the rogue AP, such as SSID, MAC address, channel, and signal strength.
Locate the Rogue Device:
Use the detecting AP ' s radio information and signal strength to triangulate the rogue AP ' s physical location.
Respond to the Threat:
Remove or disable the rogue device.
Notify the security team for further investigation.
Prevent Future Misuse:
Strengthen security policies, such as enabling client whitelists or enhancing WIPS protection.

NEW QUESTION # 108
You manage AOS-10 APs with HPE Aruba Networking Central. A role is configured on these APs with the following rules:
* Allow UDP on port 67 to any destination
* Allow any to network 10.1.6.0/23
* Deny any to network 10.1.0.0/16 + log
* Deny any to network 10.0.0.0/8
* Allow any to any destination
You add this new rule immediately before rule 2:
Deny SSH to network 10.1.4.0/23 + denylist
What happens when a client assigned to this role sends SSH traffic to 10.1.11.42?
Answer: B
Explanation:
Comprehensive Detailed Explanation
* Traffic Match Evaluation Order:
* The rules are processed in sequential order, and the first rule that matches is applied.
* The added rule only denies SSH traffic to 10.1.4.0/23. Since 10.1.11.42 is not within the 10.1.4.0
/23 subnet, this rule does not apply.
* Next Matching Rule:
* Rule 2 permits traffic to the 10.1.6.0/23 network, but this does not include 10.1.11.42.
* Rule 3 denies traffic to the broader 10.1.0.0/16 network and logs it. Since 10.1.11.42 falls under this range, this rule applies, and the traffic would be logged and dropped.
* Logging and Denylist Actions:
* The denylist action in the new rule only applies to SSH traffic to 10.1.4.0/23. Since the destination is outside that range, the denylist is not triggered.

NEW QUESTION # 109
HPE Aruba Networking ClearPass Device Insight (CPDI) could not classify some endpoints using system and user rules. Using machine learning, it did assign those endpoints to a cluster and discover a recommendation. In which of these circumstances does CPDI automatically classify the endpoints based on that recommendation?
Answer: C
Explanation:
HPE Aruba Networking ClearPass Device Insight (CPDI) uses machine learning to assign endpoints to clusters and provide classification recommendations. For CPDI to automatically classify endpoints, specific thresholds of confidence and supporting classified devices must be met.
The generally required thresholds are:
Minimum Confidence Level: Typically, CPDI requires a recommendation confidence level of at least 95%.
Minimum Supporting Devices: CPDI needs a cluster to include at least 10 classified devices to ensure the recommendation is statistically meaningful.
NEW QUESTION # 110
A security administrator at a company detects unauthorized devices attempting to connect to the network. The company uses Aruba ClearPass for authentication.
Which solution should the administrator implement to automatically detect and block unauthorized devices?
Answer: C
NEW QUESTION # 111
You have run an Active Endpoint Security Report on HPE Aruba Networking ClearPass. The report indicates that hundreds of endpoints have MAC addresses but no known IP addresses.
What is one step for addressing this issue?
Answer: C
Explanation:
When the Active Endpoint Security Report on HPE Aruba Networking ClearPass indicates that endpoints have MAC addresses but no known IP addresses, one effective step to address this issue is to add CPPM's (ClearPass Policy Manager) IP address to the IP helper list on routing switches. This configuration ensures that DHCP requests are forwarded to the ClearPass server, allowing it to track and report the IP addresses assigned to the endpoints. This helps ClearPass maintain an accurate mapping of MAC addresses to IP addresses, improving endpoint visibility and security management.
Reference: ClearPass configuration guides and best practices documentation outline the importance of integrating ClearPass with network infrastructure using IP helper addresses to ensure comprehensive endpoint visibility and management.
