HP Aruba Certified Network Security Professional Exam Sample Questions (Q17-Q22):NEW QUESTION # 17
You want to examine the applications that a device is using and look for any changes in application usage over several different ranges. In which HPE Aruba Networking solution can you view this information in an easy-to-view format?
A. HPE Aruba Networking ClearPass Insight using an Active Endpoint Security report
B. HPE Aruba Networking ClearPass OnGuard agent installed on the device
C. HPE Aruba Networking Central within a device's Live Monitoring page
D. HPE Aruba Networking ClearPass Device Insight (CPDI) in the device's network activity
Answer: C
Explanation:
* HPE Aruba Central Live Monitoring:
* Aruba Central provides real-time Live Monitoring of network devices, including:
* Application usage statistics.
* Trends and changes over time for specific devices.
* This information is presented in a clear and easy-to-read format, making it ideal for examining changes in application usage over different time ranges.
* Option Analysis:
* Option A: Incorrect. ClearPass OnGuard monitors endpoint compliance (e.g., antivirus, OS version) but does not analyze application usage.
* Option B: Correct. Aruba Central's Live Monitoring page is specifically designed for this type of analysis.
* Option C: Incorrect. ClearPass Insight generates endpoint security reports but does not track application usage.
* Option D: Incorrect. ClearPass Device Insight (CPDI) focuses on device profiling and identification, not continuous application monitoring.
NEW QUESTION # 18
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 DHCP snooping on VLANs 10-19 on Switch-2.
B. Configure Switch-1 uplinks as trusted ARP inspection ports.
C. Create a static IP-to-MAC binding on Switch-1 for the DHCP server.
D. Configure ARP inspection on VLANs 10-19 on Switch-2.
Answer: B
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 # 19
You are setting up HPE Aruba Networking SSE to prohibit users from uploading and downloading files from Dropbox. What is part of the process?
A. Adding a web category that includes Dropbox
B. Deploying a connector that can reach Dropbox
C. Installing the HPE Aruba Networking SSE root certificate on clients
D. Deploying a connector that can reach the remote users
Answer: A
Explanation:
Comprehensive Detailed Explanation
To prohibit users from uploading and downloading files from Dropbox using HPE Aruba Networking SSE (Secure Service Edge), you need to configure web access policies. This typically involves:
* Adding a web category to the SSE configuration that includes Dropbox.
* The SSE solution uses category-based filtering to block access to specific applications or services, such as Dropbox, based on their classification.
Other Options:
* B. Installing the SSE root certificate is required for enabling SSL inspection, but this does not directly control access to Dropbox.
* C and D. Deploying a connector is not necessary for this purpose as the enforcement is done via SSE policies, not by directly interfacing with Dropbox or remote users.
References
* Aruba Networking SSE documentation on web filtering policies.
* HPE Aruba SSE Application Control Best Practices Guide.
NEW QUESTION # 20
You have configured an AOS-CX switch to implement 802.1X on edge ports. Assume ports operate in the default auth-mode. VoIP phones are assigned to the "voice" role and need to send traffic that is tagged for VLAN 12. Where should you configure VLAN 12?
A. As the trunk native VLAN on edge ports and the trunk native VLAN on the "voice" role.
B. As the trunk native VLAN in the "voice" role (and not in the edge port settings).
C. As the allowed trunk VLAN in the "voice" role (and not in the edge port settings).
D. As a trunk allowed VLAN on edge ports and the trunk native VLAN in the "voice" role.
Answer: C
Explanation:
* Voice Role VLAN Configuration:
* When VoIP phones are authenticated and assigned to the "voice" role, VLAN 12 should be explicitly defined as an allowed trunk VLAN within the role configuration.
* The VLAN configuration should be role-specific rather than on the edge port, as this ensures dynamic VLAN assignment based on authentication results.
* Option Analysis:
* Option A: Incorrect. Native VLANs are for untagged traffic, but VoIP traffic is tagged.
* Option B: Correct. VLAN 12 must be configured as the allowed trunk VLAN in the "voice" role to tag VoIP traffic correctly.
* Option C: Incorrect. Configuring VLAN 12 in both edge port and role settings is redundant and unnecessary.
* Option D: Incorrect. Native VLANs do not handle tagged traffic like VLAN 12 for VoIP phones.
NEW QUESTION # 21
You have downloaded a packet capture that you generated on HPE Aruba Networking Central. When you open the capture in Wireshark, you see the output shown in the exhibit.
What should you do in Wireshark so that you can better interpret the packets?
A. Apply the following display filter: wlan.fc.type == 1.
B. Edit the Enabled Protocols and make sure that 802.11, GRE, and Aruba_ERM are enabled.
C. Choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0.
D. Edit preferences for IEEE 802.11 and chose to ignore the Protection bit with IV.
Answer: C
Explanation:
To better interpret the packets shown in the Wireshark capture, you should choose to decode UDP port 5555 packets as ARUBA_ERM and set the Aruba ERM Type to 0. This configuration will allow Wireshark to properly decode and display the Aruba-specific encapsulated remote mirroring (ERM) packets, providing a clearer understanding of the traffic.
1.Decoding Protocols: Selecting the correct protocol decoding in Wireshark ensures that the captured packets are interpreted correctly, displaying the relevant information.
2.Aruba ERM: The packets in the capture are likely encapsulated remote mirroring (ERM) packets specific to Aruba, which require proper decoding settings in Wireshark.
3.Clear Interpretation: By setting the Aruba ERM Type to 0 and decoding the packets as ARUBA_ERM, you can view the encapsulated data accurately.
