NEW QUESTION # 68
HPE Aruba Networking Central displays an alert about an Infrastructure Attack that was detected.
You go to the Security > RAPIDS events and see that the attack was "Detect adhoc using Valid SSID." What is one possible next step?
- A. Make sure that you have tuned the threshold for that check as false positives are common for it.
- B. Look for the IP address associated with the offender and then check for that IP address among HPE Aruba Networking Central clients.
- C. Make sure that clients have updated drivers, as faulty drivers are a common explanation for this attack type.
- D. Use HPE Aruba Networking Central floorplans or the detecting AP identities to locate the general area for the threat.
Answer: D
Explanation:
* RAPIDS Ad-Hoc Detection:
* The alert "Detect ad-hoc using Valid SSID" indicates that a device is broadcasting an SSID that matches a valid network SSID in ad-hoc mode. This can be an indication of an infrastructure attack or misconfiguration.
* Next Steps:
* Use Aruba Central floorplans or AP location data to identify the physical area where the offending device is detected.
* Locate and investigate the device to determine if it is malicious or simply misconfigured.
* Option Analysis:
* Option A: Incorrect. While tuning thresholds is useful for reducing false positives, this step does not directly address a potential threat.
* Option B: Incorrect. Faulty drivers can cause similar behavior, but this step is not immediately actionable without locating the device first.
* Option C: Correct. Floorplans or AP identities help locate the threat's physical area for further investigation.
* Option D: Incorrect. RAPIDS focuses on detecting devices via SSID and MAC, not IP addresses, making this approach less relevant.
NEW QUESTION # 69
A company has AOS-CX switches, which authenticate clients to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM is set up to receive a variety of information about clients' profile and posture. New information can mean that CPPM should change a client's enforcement profile. What should you set up on the switches to help the solution function correctly?
- A. Enable RADIUS accounting to CPPM, including interim RADIUS accounting.
- B. Re-configure the authentication server on the switch specifying CPPM as a TACACS server.
- C. Enable dynamic authorization, and specify CPPM as a dynamic authorization client.
- D. Configure a RADIUS track that references CPPM's FQDN or IP address.
Answer: C
Explanation:
* Dynamic Authorization for Enforcement Profile Updates:
* When CPPM receives updated client posture or profile data, it can initiate a Change of Authorization (CoA) to update enforcement profiles dynamically.
* To support this:
* Dynamic Authorization must be enabled on the switches.
* CPPM must be configured as a dynamic authorization client to send CoA requests.
* Option C: Correct. Dynamic authorization ensures that the switch can apply updated enforcement profiles based on new information from CPPM.
* Option A: Incorrect. RADIUS accounting provides session updates but does not enable dynamic changes to enforcement profiles.
* Option B: Incorrect. RADIUS track is for monitoring RADIUS server availability, not dynamic enforcement updates.
* Option D: Incorrect. TACACS is not used for dynamic authorization; RADIUS handles this functionality.
NEW QUESTION # 70
A company has a variety of HPE Aruba Networking solutions, including an HPE Aruba Networking infrastructure and HPE Aruba Networking ClearPass Policy Manager (CPPM). The company passes traffic from the corporate LAN destined to the data center through a third-party SRX firewall. The company would like to further protect itself from internal threats.

This service allows you to define and enforce specific command sets and access privileges for users authenticated via TACACS+. Byconfiguring the Shell service in the enforcement profile, you can specify the commands that are permitted or denied for the managers, ensuring controlled and secure access to the switch's command-line interface.
NEW QUESTION # 76
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. Role mapping policy
- B. Authentication methods
- C. Authentication source
- D. Service rules
Answer: D
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
A company has a third-party security appliance deployed in its data center. The company wants to pass all traffic for certain clients through that device before forwarding that traffic toward its ultimate destination.
Which AOS-CX switch technology fulfills this use case?
- A. Device profiles
- B. MC-LAG
- C. Network Analytics Engine (NAE)
- D. Virtual Network Based Tunneling (VNBT)
Answer: D
Explanation:
Comprehensive Detailed Explanation
Virtual Network Based Tunneling (VNBT) is the appropriate technology for this use case because:
* Traffic Steering: VNBT enables traffic from specific clients or devices to be tunneled through a predefined network path. This allows traffic to pass through intermediate devices such as third-party security appliances.
* Policy Enforcement: VNBT can be configured to route traffic based on roles, VLANs, or other policy definitions, ensuring that only specified traffic flows are redirected to the security appliance.
* Scalability: This approach simplifies the redirection of traffic without requiring complex physical rewiring or changes to the underlying network topology.
Other Options:
* MC-LAG: Primarily used for high-availability and redundancy in multi-chassis link aggregation scenarios, not for traffic redirection through appliances.
* Network Analytics Engine (NAE): Used for monitoring and analytics, not traffic steering or forwarding.
* Device Profiles: Helps automate switch port configurations for specific device types but does not handle traffic redirection.

NEW QUESTION # 78
A port-access role for AOS-CX switches has this policy applied to it:
plaintext
Copy code
port-access policy mypolicy
10 class ip zoneC action drop
20 class ip zoneA action drop
100 class ip zoneB
The classes have this configuration:
plaintext
Copy code
class ip zoneC
10 match tcp 10.2.0.0/16 eq https
class ip zoneA
10 match ip any 10.1.0.0/16
class ip zoneB
10 match ip any 10.0.0.0/8
The company wants to permit clients in this role to access 10.2.12.0/24 with HTTPS. What should you do?
- A. Add this rule to zoneA: 5 ignore tcp any 10.2.12.0/24 eq https
- B. Add this rule to zoneB: 5 match tcp any 10.2.12.0/24 eq https
- C. Add this rule to zoneC: 5 ignore tcp any 10.2.12.0/24 eq https
- D. Add this rule to zoneC: 5 match any 10.2.12.0/24 eq https
Answer: D
Explanation:
Comprehensive Detailed Explanation
* The requirement is to permit HTTPS traffic from clients to the 10.2.12.0/24 subnet.
* ZoneC is configured to drop all HTTPS traffic to the 10.2.0.0/16 subnet. Therefore, the first match in the zoneC class (priority 10) will drop the desired traffic.
* To override this behavior, you must add a higher-priority rule (lower rule number) to zoneC that explicitly matches 10.2.12.0/24 and permits the traffic.
Thus, adding the rule 5 match any 10.2.12.0/24 eq https to zoneC ensures the desired traffic is permitted while maintaining the drop behavior for the rest of 10.2.0.0/16.

NEW QUESTION # 80
A company has AOS-CX switches at the access layer, managed by HPE Aruba Networking Central. You have identified suspicious activity on a wired client. You want to analyze the client's traffic with Wireshark, which you have on your management station.
What should you do?
- A. Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture.
- B. Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port.
- C. Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port.
- D. Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination.
Answer: D
Explanation:
Why a Mirror Session Is the Correct Choice
To analyze a wired client's traffic with Wireshark, you need the traffic mirrored to your management station where Wireshark is installed. The most effective way to achieve this is by configuring a mirror session on the AOS-CX switch, specifying the client port as the source and your management station as the destination.
Analysis of Each Option
A: Access the client's switch's CLI from your management station. Access the switch shell and run a TCP dump on the client port:
* Incorrect:
* AOS-CX switches do not natively support packet capture (e.g., tcpdump) directly on the switch CLI.
* This approach is not feasible for capturing and analyzing live client traffic.
B: Go to the client's switch in HPE Aruba Networking Central. Use the "Security" page to run a packet capture:
* Incorrect:
* HPE Aruba Networking Central provides security insights but does not directly support initiating packet captures for detailed analysis.
* Traffic analysis with tools like Wireshark requires local packet capture at the management station.
C: Set up a policy that implements a captive portal redirect to your management station. Apply that policy to the client's port:
* Incorrect:
* Captive portals are designed for user authentication and redirection, not traffic analysis.
* This would disrupt the client's network activity without enabling traffic analysis in Wireshark.
D: Set up a mirror session on the client's switch; set the client port as the source and your station IP address as the tunnel destination:
* Correct:
* Mirroring the client port to your management station is the standard method for analyzing live network traffic with Wireshark.
* Steps include:
* Configure a mirror session on the client's AOS-CX switch.
* Set the client's port as the source.
* Set your management station as the destination using its IP address (via GRE tunnel or physical interface).
* Start capturing traffic with Wireshark on the management station.
Final Recommendation
To analyze the client's traffic, configure a mirror session on the switch, set the client port as the source, and direct the traffic to your management station where Wireshark is running.

NEW QUESTION # 81
An AOS-CX switch has been configured to implement UBT to a cluster of three HPE Aruba Networking gateways.
How does the switch determine to which gateways to tunnel UBT users' traffic?
- A. The switch tunnels each user's traffic to the particular gateway assigned as that user's active user designed gateway.
- B. The switch tunnels all users' traffic to the gateway assigned as the switch's active device designated gateway.
- C. The switch tunnels all users' traffic to the gateway configured as the primary gateway in the UBT zone, unless that gateway fails.
- D. The switch load balances client traffic across the primary and standby gateway configured in the UBT zone.
Answer: A
Explanation:
When an AOS-CX switch implements User-Based Tunneling (UBT) to a cluster of three HPE Aruba Networking gateways, the switch determines to which gateway to tunnel each user's traffic based on the particular gateway assigned as that user's active user designated gateway. This ensures that traffic is efficiently distributed and managed according to the designated gateway for each user.
1.User Designated Gateway: Each user's traffic is tunneled to a specific gateway that has been designated for that user, ensuring efficient handling of traffic.
2.Traffic Distribution: This method allows for balanced distribution of user traffic across multiple gateways, enhancing network performance and reliability.
3.Gateway Assignment: The switch uses the assigned gateway for each user to determine the tunneling path, ensuring that traffic is directed to the appropriate gateway.
