HPE7-A02 Dumps with Practice Exam Questions Answers

1. The Need for Faster Threat Notifications

Admins need immediate alerts when threats are detected by the gateway's IDS/IPS functionality. Regularly checking the Security Dashboard is inefficient, so an automated notification system is essential for faster response times.

2. Explanation of Each Option

A. Set up Webhooks that are attached to the HPE Aruba Networking Central Threat Dashboard:

Incorrect:

Webhooks are useful for integrating alerts with third-party tools or custom workflows. However, setting up email notifications through global alert settings is faster and simpler for this purpose.

B. Use Syslog to integrate the gateways with HPE Aruba Networking ClearPass Policy Manager (CPPM) event processing:

Incorrect:

Syslog integration with CPPM is typically used for logging and correlating events, not for real-time notifications about threats.

CPPM is better suited for policy enforcement, not instant threat alerts.

C. Set up email notifications using HPE Aruba Networking Central's global alert settings:

Correct:

HPE Aruba Networking Central has global alert settings that allow admins to configure email notifications for specific events, such as threat detection.

This is the simplest and most effective way to ensure admins receive immediate notifications when threats are detected by the gateways.

D. Integrate HPE Aruba Networking ClearPass Device Insight (CPDI) with Central and schedule hourly reports:

Incorrect:

While CPDI integration provides enhanced device profiling, it is not directly tied to gateway IDS/IPS threat detection.

Hourly reports are not real-time notifications and would not meet the requirement for faster threat alerts.

Final Recommendation

Setting up email notifications through HPE Aruba Networking Central's global alert settings provides the most direct and efficient solution for immediate threat detection alerts.

For a company that lacks visibility into various types of user and IoT devices on its internal network, HPE Aruba Networking ClearPass Device Insight (CPDI) is the recommended solution. CPDI provides comprehensive visibility and profiling of all devices connected to the network. It uses machine learning and AI to identify and classify devices, offering detailed insights into their behavior and characteristics. This enhanced visibility enables the security team to effectively monitor and manage network devices, improving overall network security and compliance.

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.

For a faster way to discover if a gateway starts detecting threats in traffic, admins should set up email notifications using HPE Aruba Networking Central's global alert settings. This setup ensures that the security team is promptly informed via email whenever the IDS/IPS on the gateways detects any threats, allowing for immediate investigation and response.

1.Email Notifications: By configuring email notifications, admins can receive real-time alerts directly to their inbox, reducing the time to discover and react to security incidents.

2.Global Alert Settings: HPE Aruba Networking Central's global alert settings allow for customization of alerts based on specific security events and thresholds, providing flexibility in monitoring and response.

3.Proactive Monitoring: This proactive approach ensures that the security team is always aware of potential threats without the need to constantly check the Security Dashboard manually.

To control which commands managers are allowed to enter on AOS-CX switches using HPE Aruba Networking ClearPass Policy Manager (CPPM) as a TACACS+ server, you need to add the Shell service to the TACACS+ enforcement profiles for the managers. This service allows you to define and enforce specific command sets and access privileges for users authenticated via TACACS+. By configuring the Shell service in the enforcement profile, you can specify the commands that are permitted or denied for the managers, ensuring controlled and secure access to the switch's command-line interface.
