Question 36

Refer to Exhibit:

All of the switches in the exhibit are AOS-CX switches.
What is the preferred configuration on Switch-2 for preventing rogue OSPF routers in this network?

Correct Answer: B
Why MD5 Authentication on Lag 1 is Preferred:
* Lag 1 is the primary link between Switch-2 and Switch-1, both of which are Layer 3 switches running OSPF.
* By enabling MD5 authentication, OSPF routers exchange authenticated packets, preventing unauthorized or rogue OSPF routers from forming adjacencies or injecting routes.
* MD5 is a secure authentication method and ensures the integrity and authenticity of OSPF communications.
Other Options Analysis:
* A. Configure OSPF authentication on VLANs 10-19 in password mode: While configuring authentication on VLAN interfaces could secure VLAN-specific OSPF traffic, it is less effective because the main threat of rogue OSPF comes from unauthorized L3 devices connected via the backbone (Lag 1).
* C. Disable OSPF entirely on VLANs 10-19: Disabling OSPF on these VLANs is not a preferred solution because OSPF is needed to route traffic in this design.
* D. Configure passive-interface as the OSPF default and disable OSPF passive on Lag 1: While passive interfaces prevent OSPF from forming adjacencies, it does not directly prevent rogue routers.
Passive mode only limits OSPF advertisements on specific interfaces.

Question 37

You have configured an AOS-CX switch to implement 802.1X on edge ports. Assume ports operate in the default auth-mode. VolP phones are assigned to the
"voice" role and need to send traffic that is tagged for VLAN 12.
Where should you configure VLAN 12?

Correct Answer: D
When configuring 802.1X authentication on edge ports of an AOS-CX switch and assigning VoIP phones to a "voice" role, the correct approach is to configure VLAN 12 as the allowed trunk VLAN in the "voice" role.
This setup ensures that traffic tagged for VLAN 12 is appropriately managed by the role applied to the VoIP phones. In AOS-CX switches, the role-based VLAN configuration allows for more granular control and ensures that the VoIP phones' traffic is handled correctly without altering the edge port settings, which typically operate with default settings for authentication.

Question 38

A company is implementing a client-to-site VPN based on tunnel-mode IPsec.
Which devices are responsible for the IPsec encapsulation?

Correct Answer: C
In a client-to-site VPN based on tunnel-mode IPsec, the remote clients and a gateway at the main site are responsible for the IPsec encapsulation. The remote clients initiate the VPN connection and encapsulate their traffic in IPsec, which is then decapsulated by the gateway at the main site.
1.IPsec Encapsulation: The remote clients encapsulate their traffic using IPsec protocols before sending it over the internet to the main site.
2.Gateway Role: The gateway at the main site receives the encapsulated traffic, decapsulates it, and forwards it to the internal network. Similarly, traffic from the main site to the remote clients is encapsulated by the gateway and decapsulated by the clients.
3.Security: This setup ensures that data is securely transmitted between the remote clients and the main site, protecting it from eavesdropping and tampering.

Question 39

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?

Correct Answer: A
When HPE Aruba Networking Central detects an Infrastructure Attack, such as "Detect adhoc using Valid SSID," the next step is to locate the general area of the threat. You can use HPE ArubaNetworking Central floorplans or the identities of the detecting APs to pinpoint the approximate location of the adhoc network.
This allows you to physically investigate and address the source of the threat, ensuring that unauthorized or rogue networks are quickly identified and mitigated.

Question 40

You are setting up HPE Aruba Networking SSE. Which use case requires you to apply a non-default device posture in a rule?

Correct Answer: B
Comprehensive Detailed Explanation
A non-default device posture is applied in scenarios where specific checks on a device's compliance or security state (posture) are required to grant or deny access. The correct answer is:
* B. Checking whether a client has antivirus software as a condition for receiving access to resources.
* This use case explicitly requires device posture assessment, which involves evaluating the device for attributes like antivirus software, patch levels, or other compliance criteria.
* Non-default device posture rules are configured to assess these conditions and enforce the appropriate policy based on the device's state.
Other Options:
* A. Applying threat inspection: Threat inspection rules operate independently of device posture and apply based on traffic content, not device compliance.
* C. Redirecting compromised clients: This action is typically triggered based on a security event or threat detection, not directly related to device posture evaluation.
* D. Integrating with ClearPass OnGuard: While OnGuard can contribute to posture assessment, it does not require a non-default device posture in the SSE rule directly.

* Aruba ClearPass and SSE Integration Deployment Guide.
