NEW QUESTION # 134
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 # 135
A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application).
You have identified a device, which is currently
classified as one type, but you want to classify it as a custom type. You also want to classify all devices with similar attributes as this type, both already-discovered devices and new devices discovered later.
What should you do?
Answer: B
Explanation:
When using HPE Aruba Networking ClearPass Device Insight (CPDI) and you need to reclassify a device to a custom type and apply this classification to all devices with similar attributes, both already discovered and newly discovered, you should follow these steps:
1.Navigate to the device details in CPDI.
2.Select the option to reclassify the device.
3.Create a user rule based on the desired attributes of the device.
4.Choose the "Save & Reclassify" option.
This process ensures that the device is reclassified according to the new custom type and that the rule is applied to all existing and future devices with matching attributes, maintaining consistent classification across the network.
Reference: The ClearPass Device Insight user guide includes detailed instructions on device classification, rule creation, and managing device attributes to maintain accurate network visibility and security.
NEW QUESTION # 136
Refer to the exhibit.
You are reviewing packets in Wireshark. The capture shows traffic from source IP address
10.1.14.10 to several destinations in the 10.1.15.0/24 network. The packets use TCP flags FIN, PSH, and URG together.
What can you interpret from the packets that you see here?
Answer: C
Explanation:
The packets show TCP traffic with the FIN, PSH, and URG flags set together. This combination is commonly associated with an Xmas scan, a TCP port scanning technique used to probe target systems and identify open, closed, or filtered ports. A normal TCP session establishment uses a SYN packet first, not FIN/PSH/URG. Because the source host 10.1.14.10 is sending this unusual TCP flag combination to multiple destinations and ports, the behavior strongly indicates reconnaissance or scanning activity rather than legitimate application traffic. It is not best classified as a DoS attack because the exhibit shows probing traffic, not traffic volume or exhaustion behavior. The strongest interpretation is that 10.1.14.10 is almost certainly running a TCP port scan.
NEW QUESTION # 137
Refer to Exhibit:
All of the switches in the exhibit are AOS-CX switches.
What is the preferred configuration on Switch-2 for preventing rogue OSPF routers in this network?
Answer: D
Explanation:
Why MD5 Authentication on Lag 1 is Preferred:
Lag 1 is the primary link between Switch-2 and Switch-1, both of which are Layer 3 switches running OSPF.
By enabling MD5 authentication, OSPF routers exchange authenticated packets, preventing unauthorized or rogue OSPF routers from forming adjacencies or injecting routes.
MD5 is a secure authentication method and ensures the integrity and authenticity of OSPF communications.
Other Options Analysis:
A). Configure OSPF authentication on VLANs 10-19 in password mode: While configuring authentication on VLAN interfaces could secure VLAN-specific OSPF traffic, it is less effective because the main threat of rogue OSPF comes from unauthorized L3 devices connected via the backbone (Lag 1).
C). Disable OSPF entirely on VLANs 10-19: Disabling OSPF on these VLANs is not a preferred solution because OSPF is needed to route traffic in this design.
D). Configure passive-interface as the OSPF default and disable OSPF passive on Lag 1: While passive interfaces prevent OSPF from forming adjacencies, it does not directly prevent rogue routers. Passive mode only limits OSPF advertisements on specific interfaces.
NEW QUESTION # 138
A company uses HPE Aruba Networking ClearPass Policy Manager (CPPM) and HPE Aruba Networking ClearPass Device Insight (CPDI) and has integrated the two. CPDI admins have created a tag. CPPM admins have created rules that use that tag in the wired 802.1X and wireless 802.1X services' enforcement policies.
The company requires CPPM to apply the tag-based rules to a client directly after it learns that the client has that tag.
What is one of the settings that you should verify on CPPM?
Answer: C
Explanation:
To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) applies tag-based rules to a client immediately after learning the client has that tag, verify that both 802.1X services have the "Profile Endpoints" option enabled and an appropriate Change of Authorization (CoA) profile selected in the Profiler tab. This setup ensures that when a device is profiled and tagged, CPPM can immediately enforce the updated policies through CoA.
1.Profile Endpoints: Enabling this option ensures that endpoint profiling is active, allowing CPPM to gather and use device information dynamically.
2.CoA Profile: Selecting an appropriate CoA profile ensures that CPPM can push policy changes immediately to the network devices, applying the new rules without delay.
3.Real-Time Enforcement: This configuration allows for the immediate application of new tags and associated policies, ensuring compliance with security requirements.
