NEW QUESTION # 49
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?
- A. Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat.
- B. 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.
- C. Admins have likely misconfigured SSID security settings on some of the company's APs. You should have them check those settings.
- D. 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.
Answer: D
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 # 51
A company is using HPE Aruba Networking Central SD-WAN Orchestrator to establish a hub-spoke VPN between branch gateways (BGWs) at 1164 site and VPNCs at multiple data centers. What is part of the configuration that admins need to complete?
- A. At the global level, create default IPsec policies for the SD-WAN Orchestrator to use.
- B. In BGWs' and VPNCs' groups, create default IKE policies for the SD-WAN Orchestrator to use.
- C. In BGWs' groups, select the VPNCs to which to connect in a DC preference list.
- D. In VPNCs' groups, establish VPN pools to control which branches connect to which VPNCs.
Answer: C
Explanation:
* Hub-Spoke VPN Configuration:
* HPE Aruba Central SD-WAN Orchestrator enables hub-spoke topology where branch gateways (BGWs) connect to VPN concentrators (VPNCs) located at data centers.
* A key step in configuring this is defining which VPNCs the BGWs will prefer for connectivity.
* The DC Preference List is configured in the BGW groups to prioritize the data centers to which BGWs connect.
* Option Analysis:
* Option A: Incorrect. VPN pools control IP allocation, not which branches connect to VPNCs.
* Option B: Incorrect. IKE policies define key exchange mechanisms but are not part of the connection preference process.
* Option C: Correct. Admins configure a DC preference list in BGW groups to determine connectivity priorities with VPNCs.
* Option D: Incorrect. IPsec policies define encryption parameters at a global level, but this is not specific to the hub-spoke connection configuration.
NEW QUESTION # 52
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. Adding 802.1X while continuing to use the existing VLAN and ACL structure in the Ethernet network
- D. Tunneling traffic directly to a third-party firewall in a client data center
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.
