HP Aruba Certified Network Security Professional Exam Sample Questions (Q112-Q117):

NEW QUESTION # 112
You need to set up an HPE Aruba Networking VIA solution for a customer who needs to support 2100 remote employees. The customer wants employees to download their VIA connection profile from the VPNC. Only employees who authenticate with their domain credentials to HPE Aruba Networking ClearPass Policy Manager (CPPM) should be able to download the profile. (A RADIUS server group for CPPM is already set up on the VPNC.) How do you configure the VPNC to enforce that requirement?

  • A. Reference CPPM's server group in an AAA profile; then, apply that profile to the VPNC's Internet-facing ports.
  • B. Set up a VIA Authentication Profile that uses CPPM's server group; reference that profile in the VIA Connection Profile.
  • C. Set up a VIA Authentication Profile that uses CPPM's server group; reference that profile in the VIA Web Authentication Profile.
  • D. Create a new VPN Authentication Profile and then reference CPPM's default server group in that profile.

Answer: C

Explanation:
To configure the HPE Aruba Networking VIA solution for remote employees who need to download their VIA connection profile from the VPN Concentrator (VPNC) and ensure that only those who authenticate with their domain credentials through ClearPass Policy Manager (CPPM) can do so, you need to set up a VIA Authentication Profile. This profile should use the CPPM's RADIUS server group. Once the VIA Authentication Profile is created, you need to reference this profile in the VIA Web Authentication Profile.
This configuration ensures that the authentication process requires employees to validate their credentials via CPPM before they can download the VIA connection profile.


NEW QUESTION # 113
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. 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.
  • B. Clients are failing to authenticate to corporate SSIDs. You should first check for misconfigured authentication settings and then investigate a possible threat.
  • C. Admins have likely misconfigured SSID security settings on some of the company's APs. You should have them check those settings.
  • 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.

Answer: A

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 # 114
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. In BGWs' and VPNCs' groups, create default IKE policies for the SD-WAN Orchestrator to use.
  • B. In VPNCs' groups, establish VPN pools to control which branches connect to which VPNCs.
  • C. At the global level, create default IPsec policies for the SD-WAN Orchestrator to use.
  • D. In BGWs' groups, select the VPNCs to which to connect in a DC preference list.

Answer: D

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 # 115
Refer to the exhibit.

You have verified that AOS-CX Switch-1 has constructed an IP-to-MAC binding table in VLANs 10-19.
Now you need to enable ARP inspection for the endpoint connected to Switch-1. What must you do first to prevent traffic disruption?

  • A. Configure Switch-1 uplinks as trusted ARP inspection ports.
  • B. Configure ARP inspection on VLANs 10-19 on Switch-2.
  • C. Create a static IP-to-MAC binding on Switch-1 for the DHCP server.
  • D. Configure DHCP snooping on VLANs 10-19 on Switch-2.

Answer: A

Explanation:
Dynamic ARP Inspection (DAI):
* ARP inspection verifies ARP packets against a trusted IP-to-MAC binding table to prevent ARP spoofing attacks.
* DHCP snooping is required to construct the IP-to-MAC binding table dynamically.
* To avoid traffic disruption, uplink ports that connect to trusted switches, DHCP servers, or routers must be explicitly configured as trusted ports for ARP inspection.
Steps to Prevent Traffic Disruption:
* Trust the Uplinks: ARP inspection must treat uplink ports as trusted to allow ARP traffic from legitimate DHCP servers and upstream switches.
* Enable DHCP Snooping: DHCP snooping must be enabled on Switch-2 to ensure consistent IP-to- MAC bindings upstream.
Why the Answer is Correct:
* Option A: Incorrect. ARP inspection on Switch-2 is important but not required first to prevent disruption on Switch-1.
* Option B: Incorrect. DHCP snooping must be enabled upstream eventually, but this alone will not stop immediate traffic disruption on Switch-1.
* Option C: Correct. Switch-1 uplinks must be trusted ARP inspection ports first to allow legitimate upstream traffic and prevent ARP disruption.
* Option D: Incorrect. Static bindings are not required if DHCP snooping is enabled, and they are manual, limiting scalability.
Conclusion:
To avoid traffic disruption, configure Switch-1 uplinks as trusted ARP inspection ports to ensure valid ARP traffic can pass upstream and downstream.


NEW QUESTION # 116
A company has an HPE Aruba Networking ClearPass cluster with several servers. ClearPass Policy Manager (CPPM) is set up to:
. Update client attributes based on Syslog messages from third-party appliances
. Have the clients reauthenticate and apply new profiles to the clients based on the updates To ensure that the correct profiles apply, what is one step you should take?

  • A. Configure a CoA action for all tag updates in the ClearPass Device Insight integration settings.
  • B. Configure the cluster to periodically clean up (delete) unknown endpoints.
  • C. Tune the CoA delay on the ClearPass servers to a value of 5 seconds or greater.
  • D. Set the cluster's Endpoint Context Servers polling interval to a value of 5 seconds or less.

Answer: C

Explanation:
To ensure that the correct profiles apply after client attributes are updated based on Syslog messages, you should tune the Change of Authorization (CoA) delay on the ClearPass servers to a value of 5 seconds or greater. This delay allows sufficient time for the attribute updates to be processed and for the reauthentication to occur correctly, ensuring that the updated profiles are accurately applied to the clients.
1.CoA Delay: Adjusting the CoA delay ensures that the system has enough time to update client attributes and reauthenticate them properly before applying new profiles.
2.Profile Accuracy: This delay helps in preventing premature reauthentication and ensures that the most recent attribute updates are considered when applying profiles.
3.System Synchronization: Ensures synchronization between the attribute update and the reauthentication process.
