NEW QUESTION # 97
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?
Answer: B
Explanation:
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.
NEW QUESTION # 98
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?
Answer: A
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 # 99
A company has HPE Aruba Networking APs managed by HPE Aruba Networking Central. You have set up a WLAN to enforce WPA3 with 802.1X authentication.
What happens if the client fails authentication?
Answer: A
Explanation:
When WPA3 with 802.1X authentication is enforced on an HPE Aruba Networking WLAN, the authentication process strictly adheres to security standards. Here's how the process works:
1. 802.1X Authentication Workflow in WPA3
* The client must provide valid credentials (such as certificates or username/password) to authenticate with the RADIUS server via 802.1X.
* If the client fails authentication (e.g., due to invalid credentials or lack of proper configuration), the
802.1X handshake fails, and the AP terminates the connection.
2. Role Assignment in WLANs
* Default Role: The role assigned to authenticated clients after a successful 802.1X authentication. It is not applied to unauthenticated clients.
* Critical Role: This is a fallback role applied when there are issues communicating with the RADIUS server, not when authentication fails.
* Initial Role: A temporary role assigned to clients before authentication completes. However, this role is removed once the authentication process determines failure.
3. Behavior Upon Authentication Failure
* In the case of an authentication failure, the client does not get assigned to any role (default, critical, or initial) because it does not meet the conditions for network access.
* The client is dropped immediately, and no further communication is allowed until reauthentication is attempted.
Explanation of Each Option
* A. The AP assigns the client to the WLAN's default role:
* Incorrect: The default role applies only after successful authentication, not in case of authentication failure.
* B. The AP drops the client because authentication aborts:
* Correct: If the client fails authentication, the AP terminates the connection without assigning any roles.
* C. The AP assigns the client to the WLAN's critical role:
* Incorrect: The critical role is used when the AP cannot reach the RADIUS server, not when authentication fails.
* D. The AP assigns the client to the WLAN's initial role:
* Incorrect: The initial role is applied during the authentication process, but it is not retained after a failed authentication.

NEW QUESTION # 100
A company has HPE Aruba Networking APs and AOS-CX switches, as well as HPE Aruba Networking ClearPass. The company wants CPPM to have HTTP User- Agent strings to use in profiling devices.
What can you do to support these requirements?
Answer: A
Explanation:
To support the requirement for HPE Aruba Networking ClearPass Policy Manager (CPPM) to have HTTP User-Agent strings for profiling devices, you should add the CPPM server's IP address to the IP helper list in all client VLANs on routing switches. This configuration ensures that DHCP requests and other relevant client traffic are forwarded to CPPM, allowing it to capture HTTP User-Agent strings and use them for device profiling.
1.IP Helper Configuration: Adding CPPM to the IP helper list ensures that the switch forwards DHCP and other client traffic to CPPM, enabling it to gather necessary information for profiling.
2.User-Agent Strings: By receiving client traffic, CPPM can analyze HTTP headers and capture User-Agent strings, which provide valuable information about the client's device and browser.
3.Profiling Support: This approach supports the comprehensive profiling of devices, allowing CPPM to apply appropriate policies based on detailed device information.
NEW QUESTION # 101
A company is using HPE Aruba Networking ClearPass Device Insight (CPDI) (the standalone application).
In the CPDI security settings, Security Analysis is On,
the Data Source is ClearPass Devices Insight, and Enable Posture Assessment is On. You see that device has a Risk Score of 90.
What can you know from this information?
Answer: C
Explanation:
In HPE Aruba Networking ClearPass Device Insight (CPDI), a device with a Risk Score of 90 indicates that the posture is unhealthy, and CPDI has detected at least one vulnerability on the device. The risk score is a reflection of the device's security posture and detected vulnerabilities. A high risk score, such as 90, typically signifies significant security concerns, including the presenceof vulnerabilities that could be exploited, thereby categorizing the device as a high-risk asset within the network.
