NEW QUESTION # 85
A company has HPE Aruba Networking gateways that implement gateway IDS/IPS. Admins sometimes check the Security Dashboard, but they want a faster way to discover if a gateway starts detecting threats in traffic.
What should they do?
Answer: D
Explanation:
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.

NEW QUESTION # 86
A company has HPE Aruba Networking APs, which authenticate users to HPE Aruba Networking ClearPass Policy Manager (CPPM).
What does HPE Aruba Networking recommend as the preferred method for assigning clients to a role on the AOS firewall?
Answer: B
Explanation:
The preferred method for assigning clients to a role on the AOS firewall is to configure HPE Aruba Networking ClearPass Policy Manager (CPPM) to assign the role using a RADIUS enforcement profile with an Aruba-User-Role VSA (Vendor-Specific Attribute). This method allows ClearPass to dynamically assign the appropriate user roles to clients during the authentication process, ensuring that role-based access policies are consistently enforced across the network.
Reference: Aruba ClearPass documentation and RADIUS configuration guides provide detailed instructions on setting up RADIUS enforcement profiles and using the Aruba-User-Role VSA for role assignment.
NEW QUESTION # 87
A company already uses HPE Aruba Networking ClearPass Policy Manager (CPPM) as the RADIUS server for authenticating wireless clients with 802.1X. Now you are setting up 802.1X on AOS-CX switches to authenticate many of those same clients on wired connections. You decide to copy CPPM's wireless 802.1X service and then edit it with a new name and enforcement policy. What else must you change for authentication to work properly?
Answer: A
Explanation:
* 802.1X Service Rules:
* Service rules define the criteria for when a specific service applies (e.g., wireless vs. wired authentication).
* For wired 802.1X authentication to work properly, the service rules need to differentiate between wireless and wired connections.
* If you copy the wireless service, the rules likely still match wireless-specific criteria. These must be updated to include wired-specific conditions (e.g., NAS IP or port types).
* Option Analysis:
* Option A (Role mapping policy): Role mapping policies determine user roles based on attributes but are not critical for differentiating wired vs. wireless.
* Option B (Authentication methods): Authentication methods (e.g., EAP) remain the same for both wireless and wired 802.1X.
* Option C (Authentication source): Authentication sources (like AD or internal database) do not need to change.
* Option D (Service rules): Correct. Updating the service rules ensures the new 802.1X service applies specifically to wired connections.
NEW QUESTION # 88
You are proposing HPE Aruba Networking ZTNA to an organization that currently uses a third- party, IPsec-based client-to-site VPN.
What is one advantage of ZTNA that you should emphasize?
Answer: A
Explanation:
HPE Aruba Networking ZTNA (delivered as part of Aruba SSE) replaces traditional network-level VPN access with application-level access. Key security advantages highlighted in Aruba ZTNA/SSE collateral include:
Applications are no longer exposed directly to the internet; instead, they are fronted by the ZTNA service.
Inbound connectivity to private apps is outbound-only via connectors, eliminating open listening ports and shrinking the external attack surface. www6.h3c.com Users are granted access only to specific applications, not entire subnets, thereby limiting lateral movement and the blast radius of a compromise.
Aruba documentation explicitly notes that ZTNA "reduces the overall attack surface" and avoids the broad network exposure inherent in classic client-to-site VPNs.
NEW QUESTION # 89
Which use case is fulfilled by applying a time range to a firewall rule on an AOS device?
Answer: C
Explanation:
Applying a time range to a firewall rule on an AOS device fulfills the use case of enforcing the rule only during the specified time range. This allows administrators to control when specific firewall rules are active, which can be useful for implementing policies that only need to be in effect during certain hours, such as blocking or allowing access to specific resources outside of business hours.
1.Time-Based Enforcement: The firewall rule will be active only during the specified time range, ensuring that the rule's policies are enforced only when needed.
2.Use Case: This feature is useful for scenarios like limiting access to certain applications or websites during working hours, or enabling enhanced security measures during off-hours.
3.Flexibility: Provides flexibility in security policy management by allowing dynamic adjustment of rules based on time schedules.
