HPE7-A02 Exam Dumps - HP ACNSP Questions and Answers

To capture traffic from a particular wireless client for a 15-minute period and then send the traffic in a PCAP file, you should go to the client's AP in HPE Aruba Networking Central and use the "Security" page to run a packet capture. This method allows you to directly capture the client's traffic from the AP managing the wireless connection, ensuring that you gather the relevant traffic data for analysis.

1.Centralized Management: HPE Aruba Networking Central provides a centralized interface for managing and monitoring APs, making it easy to initiate packet captures.

2.Security Page: The "Security" page in Aruba Central includes tools for running packet captures, allowing you to specify the duration and other parameters.

3.Ease of Use: This approach simplifies the process by using the built-in features of Aruba Central, avoiding the need for complex CLI commands or additional hardware.

HPE Aruba Networking ClearPass Device Insight (CPDI) can show detailed information about a device's communication patterns, including how many destinations the device is accessing. CPDI provides comprehensive visibility into the behavior and activity of devices on the network, allowing the security team to track and analyze communication patterns at a glance. This information is critical for identifying anomalies and potential security threats.

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.

To simplify the setup of 802.1X authentication with HPE Aruba Networking ClearPass Policy Manager (CPPM) and ensure clients are steered to the correct VLANs for local forwarding, you should assign consistent names to VLANs of the same type across the AOS-CX switches and have user-roles reference these names. This approach allows for a more straightforward configuration and management process, as the user roles can apply consistent policies based on VLAN names rather than specific IDs. It also helps in maintaining clarity and reducing errors in VLAN assignments across different switches.

After installing an HPE Aruba Networking Network Analytic Engine (NAE) script on an AOS-CX switch, the additional step required to start the monitoring is to create an agent from the script. The agent is responsible for executing the script and collecting the monitoring data as defined by the script parameters.

1.Script Installation: Installing the script provides the logic and parameters for monitoring.

2.Agent Creation: Creating an agent from the script activates the monitoring process, allowing the NAE to begin tracking the specified function.

3.Operational Step: This step ensures that the monitoring logic is applied and the data collection starts as per the script’s configuration.

To show the security team information about MAC spoofing attempts detected by HPE Aruba Networking ClearPass Policy Manager (CPPM), you should use ClearPass Insight to run an Active Endpoint Security report. ClearPass Insight provides comprehensive reporting capabilities that include detailed information on security incidents, such as MAC spoofing attempts. By generating this report, you can provide the security team with a clear overview of the detected spoofing activities, including the endpoints involved and the context of the events.

To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) responds correctly to Syslog messages from a Check Point firewall, you need to check that the Ingress Event Dictionaries for Check Point messages are enabled. These dictionaries are necessary for CPPM to properly interpret and respond to the Syslog messages received from the firewall.

1.Event Dictionaries: Ingress Event Dictionaries allow CPPM to understand the specific format and content of Syslog messages from various sources, such as Check Point firewalls.

2.Message Interpretation: Without these dictionaries enabled, CPPM may not correctly interpret the Syslog messages, leading to a failure in triggering the expected actions.

3.Configuration Check: Ensuring that the dictionaries are enabled is crucial for the proper functioning of the event service and accurate response to security events.

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.

Dynamic Authorization for Enforcement Profile Updates:

When CPPM receives updated client posture or profile data, it can initiate a Change of Authorization (CoA) to update enforcement profiles dynamically.

To support this:

Dynamic Authorization must be enabled on the switches.

CPPM must be configured as a dynamic authorization client to send CoA requests.

Option C: Correct. Dynamic authorization ensures that the switch can apply updated enforcement profiles based on new information from CPPM.

Option A: Incorrect. RADIUS accounting provides session updates but does not enable dynamic changes to enforcement profiles.

Option B: Incorrect. RADIUS track is for monitoring RADIUS server availability, not dynamic enforcement updates.

Option D: Incorrect. TACACS is not used for dynamic authorization; RADIUS handles this functionality.

In HPE Aruba Networking ClearPass Device Insight (CPDI), the clusters shown in the exhibit represent groups of unclassified devices that CPDI's machine learning algorithms have identified as having similar attributes. These clusters are formed based on observed characteristics and behaviors of the devices, helping administrators to categorize and manage devices more effectively.

1.Machine Learning: CPDI uses machine learning to analyze device attributes and group them into clusters based on similarities.

2.Unclassified Devices: These clusters typically represent devices that have not yet been explicitly classified by admins but share common attributes that suggest they belong to the same category.

3.Management: This clustering helps in simplifying the process of managing and applying policies to groups of similar devices.
