NEW QUESTION # 70
A company is using HPE Aruba Networking Central SD-WAN Orchestrator to establish a hub-spoke VPN between branch gateways (BGWs) at 1164 site and VPNCs at multiple data centers. What is part of the configuration that admins need to complete?
Answer: C
Explanation:
* Hub-Spoke VPN Configuration:
* HPE Aruba Central SD-WAN Orchestrator enables hub-spoke topology where branch gateways (BGWs) connect to VPN concentrators (VPNCs) located at data centers.
* A key step in configuring this is defining which VPNCs the BGWs will prefer for connectivity.
* The DC Preference List is configured in the BGW groups to prioritize the data centers to which BGWs connect.
* Option Analysis:
* Option A: Incorrect. VPN pools control IP allocation, not which branches connect to VPNCs.
* Option B: Incorrect. IKE policies define key exchange mechanisms but are not part of the connection preference process.
* Option C: Correct. Admins configure a DC preference list in BGW groups to determine connectivity priorities with VPNCs.
* Option D: Incorrect. IPsec policies define encryption parameters at a global level, but this is not specific to the hub-spoke connection configuration.
NEW QUESTION # 71
You have run an Active Endpoint Security Report on HPE Aruba Networking ClearPass. The report indicates that hundreds of endpoints have MAC addresses but no known IP addresses.
What is one step for addressing this issue?
Answer: B
Explanation:
When the Active Endpoint Security Report on HPE Aruba Networking ClearPass indicates that endpoints have MAC addresses but no known IP addresses, one effective step to address this issue is to add CPPM's (ClearPass Policy Manager) IP address to the IP helper list on routing switches. This configuration ensures that DHCP requests are forwarded to the ClearPass server, allowing it to track and report the IP addresses assigned to the endpoints. This helps ClearPass maintain an accurate mapping of MAC addresses to IP addresses, improving endpoint visibility and security management.
Reference: ClearPass configuration guides and best practices documentation outline the importance of integrating ClearPass with network infrastructure using IP helper addresses to ensure comprehensive endpoint visibility and management.
NEW QUESTION # 72
You are setting up HPE Aruba Networking SSE. Which use case requires you to apply a non-default device posture in a rule?
Answer: D
Explanation:
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.

NEW QUESTION # 73
Refer to Exhibit:
An HPE Aruba Networking 9x00 gateway is part of an HPE Aruba Networking Central group that has the settings shown in the exhibit. What would cause the gateway to drop traffic as part of its IDPS settings?
Answer: D
Explanation:
1. IDPS Mode Configuration Overview
The exhibit shows the HPE Aruba Networking Central settings for the Gateway IDS/IPS configuration:
Mode: Configured for Intrusion Prevention System (IPS), meaning that the gateway actively blocks traffic identified as threats.
Fail Strategy: Configured to Block, meaning that if the gateway cannot determine the traffic ' s nature due to a system issue, it will block the traffic.
Ruleset: The gateway uses a predefined set of intrusion detection/prevention rules (ruleset version 9861), which is updated automatically every day.
2. Traffic Evaluation in IPS Mode
In IPS mode, the gateway analyzes traffic against the active ruleset:
If traffic matches a rule in the ruleset and is deemed malicious, the gateway will drop the traffic as part of its prevention mechanism.
The ruleset defines specific conditions (e.g., signatures of known attacks, protocol anomalies) under which traffic should be blocked.
3. Explanation of Each Option
A). Its site-to-site VPN connections failing:
Incorrect:
Site-to-site VPN connection issues do not directly trigger traffic drops under IDPS settings.
IDPS is focused on detecting and preventing malicious activity, not general connectivity issues.
B). Traffic matching a rule in the active ruleset:
Correct:
In IPS mode, the gateway drops traffic that matches any predefined rules in the active ruleset.
For example, if traffic matches the signature of a known exploit or attack, it is immediately blocked.
C). Its IDPS engine failing:
Incorrect:
The fail strategy determines how the gateway behaves in the event of an IDPS engine failure.
In this case, the fail strategy is set to Block, but this applies only if the engine itself fails, not as a proactive traffic drop mechanism.
D). Traffic showing anomalous behavior:
Incorrect:
While anomalous behavior may be logged or flagged, it does not necessarily lead to traffic drops unless it matches a specific rule in the active ruleset.
Anomaly detection alone is not sufficient for IPS action without explicit rule matches.
Final Outcome:
Traffic is dropped only when it matches a rule in the active ruleset, ensuring targeted prevention of malicious activity.

NEW QUESTION # 74
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: A
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.
