NEW QUESTION # 129
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: B
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 # 130
A company has HPE Aruba Networking APs managed by HPE Aruba Networking Central. You have set up a WLAN to enforce WPA3 with 802.1X authentication.
What happens if the client fails authentication?
Answer: D
Explanation:
When WPA3 with 802.1X authentication is enforced on an HPE Aruba Networking WLAN, the authentication process strictly adheres to security standards. Here's how the process works:
1. 802.1X Authentication Workflow in WPA3
The client must provide valid credentials (such as certificates or username/password) to authenticate with the RADIUS server via 802.1X.
If the client fails authentication (e.g., due to invalid credentials or lack of proper configuration), the 802.1X handshake fails, and the AP terminates the connection.
2. Role Assignment in WLANs
Default Role: The role assigned to authenticated clients after a successful 802.1X authentication. It is not applied to unauthenticated clients.
Critical Role: This is a fallback role applied when there are issues communicating with the RADIUS server, not when authentication fails.
Initial Role: A temporary role assigned to clients before authentication completes. However, this role is removed once the authentication process determines failure.
3. Behavior Upon Authentication Failure
In the case of an authentication failure, the client does not get assigned to any role (default, critical, or initial) because it does not meet the conditions for network access.
The client is dropped immediately, and no further communication is allowed until reauthentication is attempted.
Explanation of Each Option
A). The AP assigns the client to the WLAN ' s default role:
Incorrect: The default role applies only after successful authentication, not in case of authentication failure.
B). The AP drops the client because authentication aborts:
Correct: If the client fails authentication, the AP terminates the connection without assigning any roles.
C). The AP assigns the client to the WLAN ' s critical role:
Incorrect: The critical role is used when the AP cannot reach the RADIUS server, not when authentication fails.
D). The AP assigns the client to the WLAN ' s initial role:
Incorrect: The initial role is applied during the authentication process, but it is not retained after a failed authentication.

NEW QUESTION # 131
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: A
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.
NEW QUESTION # 132
A company has HPE Aruba Networking APs running AOS-10 and managed by HPE Aruba Networking Central. The company also has AOS-CX switches. The security team wants you to capture traffic from a particular wireless client. You should capture this client's traffic over a 15 minute time period and then send the traffic to them in a PCAP file.
What should you do?
Answer: D
Explanation:
To capture traffic from a particular wireless client for a 15-minute period and then send the traffic in a PCAP file, you should go to the client's AP in HPE Aruba Networking Central and use the "Security" page to run a packet capture. This method allows you to directly capture the client's traffic from the AP managing the wireless connection, ensuring that you gather the relevant traffic data for analysis.
1.Centralized Management: HPE Aruba Networking Central provides a centralized interface for managing and monitoring APs, making it easy to initiate packet captures.
2.Security Page: The "Security" page in Aruba Central includes tools for running packet captures, allowing you to specify the duration and other parameters.
3.Ease of Use: This approach simplifies the process by using the built-in features of Aruba Central, avoiding the need for complex CLI commands or additional hardware.
Reference: Aruba Central's documentation and user guides detail the steps for performing packet captures through the Central interface, including capturing traffic from specific clients and generating PCAP files for analysis.
NEW QUESTION # 133
A company has been running Gateway IDS/IPS on its gateways in IDS mode for several weeks. The company wants to transition to IPS mode.
What is one step you should recommend?
Answer: B
Explanation:
When transitioning from Intrusion Detection System (IDS) mode to Intrusion Prevention System (IPS) mode, it's critical to review and refine configurations to ensure legitimate traffic is not blocked. Here's the reasoning behind each option:
A: Disable traffic inspection and reboot before re-enabling traffic inspection with the new mode.
* Incorrect:
* Transitioning to IPS mode does not require a full reboot or disabling traffic inspection.
* This step is unnecessary and could lead to downtime that impacts network operations.
B: Change the mode on one gateway at a time to establish a smoother transition period.
* Incorrect:
* While a phased approach might help in some large deployments, it does not directly address the potential for legitimate traffic to be blocked by IPS mode.
* IPS operates in real-time, so misconfigured rules or policies need to be addressed before enabling IPS on any gateway.
C: Consider applying a stricter IPS policy to minimize issues during the transition period.
* Incorrect:
* A stricter IPS policy increases the likelihood of false positives, which could disrupt legitimate business-critical traffic.
* During the transition, the focus should be on minimizing disruptions by fine-tuning policies, not making them stricter.
D: Check for legitimate traffic that has been flagged as a threat and allow list the associated rules.
* Correct:
* In IDS mode, the system only detects and logs suspicious traffic but does not block it. Reviewing these logs for false positives allows the organization to fine-tune policies and allow list legitimate traffic before transitioning to IPS mode.
* By doing this, the company ensures that IPS mode will block actual threats while permitting legitimate traffic.
* This is a proactive step to prevent unnecessary disruptions to normal operations when IPS mode is enabled.
