What is one use case for implementing user-based tunneling (UBT) on AOS-CX switches?
- A. Applying enhanced security features such as deep packet inspection (DPI) to wired traffic
- B. Centralizing the distribution of wired traffic without requiring HPE Aruba Networking gateways
- C. Tunneling traffic directly to a third-party firewall in a client data center
- D. Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
Answer: A
Explanation:
Implementing user-based tunneling (UBT) on AOS-CX switches is beneficial for applying enhanced security features such as deep packet inspection (DPI) to wired traffic. UBT allows the traffic from specific users or devices to be tunneled to a central controller or security appliance where advanced security policies, including DPI, can be applied. This approach ensures that even wired traffic benefits from the same level of security and inspection typically available for wireless traffic, thus enhancing overall network security.
NEW QUESTION # 68
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. Right-click one of the packets between those addresses and choose to follow the stream.
- B. Apply a capture filter that selects for both the 10.1.70.90 and 10.1.79.11 IP addresses.
- C. Apply a capture filter that selects for TCP port 5448.
- D. Click the Source column and then the Destination column to sort the packets into the desired order.
Answer: A
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 # 71
A company already uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as the RADIUS server for authenticating wireless clients with 802.1X. Now you are setting up 802.1X on AOS-CX switches to authenticate many of those same clients on wired connections. You decide to copy CPPM's wireless 802.1X service and then edit it with a new name and enforcement policy. What else must you change for authentication to work properly?
- A. Authentication source
- B. Service rules
- C. Role mapping policy
- D. Authentication methods
Answer: B
Explanation:
* 802.1X Service Rules:
* Service rules define the criteria for when a specific service applies (e.g., wireless vs. wired authentication).
* For wired 802.1X authentication to work properly, the service rules need to differentiate between wireless and wired connections.
* If you copy the wireless service, the rules likely still match wireless-specific criteria. These must be updated to include wired-specific conditions (e.g., NAS IP or port types).
* Option Analysis:
* Option A (Role mapping policy): Role mapping policies determine user roles based on attributes but are not critical for differentiating wired vs. wireless.
* Option B (Authentication methods): Authentication methods (e.g., EAP) remain the same for both wireless and wired 802.1X.
* Option C (Authentication source): Authentication sources (like AD or internal database) do not need to change.
* Option D (Service rules): Correct. Updating the service rules ensures the new 802.1X service applies specifically to wired connections.

NEW QUESTION # 77
You are using Wireshark to view packets captured from HPE Aruba Networking infrastructure, but you're not sure that the packets are displaying correctly. In which circumstance does it make sense to configure Wireshark to ignore protection bits with the IV for the 802.11 protocol?
- A. When the traffic was captured from an AP with HPE Aruba Networking Central.
- B. When the traffic was mirrored from an AOS-CX switch port connected to an AP.
- C. When the traffic was captured on the control plane of an HPE Aruba Networking MC and sent to a remote IP.
- D. When the traffic was captured on the data plane of an HPE Aruba Networking gateway and sent to a remote IP.
Answer: A
Explanation:
* 802.11 Traffic and Protection Bits:
* In the 802.11 protocol, protection bits and the Initialization Vector (IV) are used in encrypted wireless traffic.
* If the traffic is captured directly from an AP, the frames may include encrypted content.
* Wireshark may misinterpret these protection bits or fail to display the frames correctly unless it is configured to ignore protection bits and correctly parse the IV.
* Key Scenario:
* When traffic is captured directly from an AP managed by HPE Aruba Networking Central, the frames are often captured before decryption occurs.
* In such cases, you must configure Wireshark to ignore the protection bits and handle the IV properly for correct frame interpretation.
* Option Analysis:
* Option A: Incorrect. Data plane traffic sent to a remote IP is usually decrypted, so Wireshark does not require this adjustment.
* Option B: Incorrect. Switch port mirroring captures traffic at Layer 2/3, not raw 802.11 frames.
* Option C: Correct. Traffic captured directly from an AP via HPE Aruba Networking Central often includes encrypted wireless frames, requiring Wireshark adjustments.
* Option D: Incorrect. Control plane traffic is typically management data and not raw wireless frames needing IV interpretation.
