Rogue AP Containment Methods:

HPE Aruba Networking recommends using wireless deauthentication as the preferred method for rogue AP containment.

Deauthentication sends deauth frames to clients connected to rogue APs, causing them to disconnect. This method is effective without introducing unnecessary disruptions to the wired infrastructure.

Key Points:

Wireless Deauthentication is simple, efficient, and widely supported across client devices.

Tarpit Containment is more aggressive and may cause unintentional disruptions to legitimate clients.

Wired Containment involves blocking traffic at the switch level but is complex and may impact legitimate infrastructure traffic.

Option Analysis:

Option A: Correct. Wireless deauthentication is the recommended method as it targets rogue AP clients without excessive network impact.

Option B: Incorrect. Combining wireless tarpit and wired containment is overkill and not typically recommended.

Option C: Incorrect. Wireless tarpit can be effective but is generally not the first choice due to its aggressive nature.

Option D: Incorrect. Wired containment is more complex and reserved for specific use cases, not general recommendations.

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.

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.

When integrating ClearPass Policy Manager (CPPM) with ClearPass Device Insight (CPDI), it is important to understand how device profiling and classification work between the two solutions:

1. CPPM and CPDI Integration Overview

CPPM is primarily used for access control and policy enforcement, while CPDI specializes in device profiling and classification through advanced analytics and machine learning.

Integration allows CPPM to leverage CPDI's enhanced profiling capabilities for more accurate device identification and policy enforcement.

2. Detailed Analysis of Each Option

A. CPPM no longer supports any Device Profiler features and relies on CPDI for this profile information:

Incorrect: CPPM still supports its own basic device profiling features and can operate independently. However, when integrated with CPDI, CPPM can use CPDI’s advanced profiling capabilities as a supplement.

B. CPDI must be configured as an audit server on CPPM for the integration to be successful:

Incorrect: CPDI is not configured as an audit server on CPPM. Integration is achieved via API integration and communication between the two solutions, not through audit server settings.

C. CPDI must have security analysis disabled on it for the integration to be successful:

Incorrect: Security analysis does not need to be disabled for integration. In fact, CPDI’s security analysis enhances the classification process by identifying anomalous behaviors.

D. CPPM can submit profile information to CPDI, but if CPDI derives a different classification, CPDI takes precedence:

Correct:

CPPM and CPDI exchange profile data, but CPDI has more advanced device classification capabilities due to its machine learning-based engine.

When CPDI derives a different classification than CPPM, CPDI's classification is considered more accurate and takes precedence.

This ensures that policies are based on the most reliable device classification.
