HPE7-A02 Exam Dumps - Aruba Certified Network Security Professional Exam

Integration of CPDI and CPPM for Zero Trust:

CPDI (ClearPass Device Insight) identifies and profiles devices and applications on the network.

CPDI can tag devices based on their behavior or detected applications.

CPPM uses these tags to enforce policies, such as quarantining clients that violate security rules (e.g., using prohibited applications).

Option Analysis:

Option A: Incorrect. CPPM does not inform CPDI about role assignments; CPDI provides device context to CPPM.

Option B: Correct. CPDI tags clients, and CPPM uses those tags to enforce quarantine or other Zero Trust actions.

Option C: Incorrect. Custom fingerprint definitions are not part of this integration.

Option D: Incorrect. CPDI provides information about devices, not user identities.

HPE Aruba Central Live Monitoring:

Aruba Central provides real-time Live Monitoring of network devices, including:

Application usage statistics.

Trends and changes over time for specific devices.

This information is presented in a clear and easy-to-read format, making it ideal for examining changes in application usage over different time ranges.

Option Analysis:

Option A: Incorrect. ClearPass OnGuard monitors endpoint compliance (e.g., antivirus, OS version) but does not analyze application usage.

Option B: Correct. Aruba Central's Live Monitoring page is specifically designed for this type of analysis.

Option C: Incorrect. ClearPass Insight generates endpoint security reports but does not track application usage.

Option D: Incorrect. ClearPass Device Insight (CPDI) focuses on device profiling and identification, not continuous application monitoring.

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.

Comprehensive Detailed Explanation

To prohibit users from uploading and downloading files from Dropbox using HPE Aruba Networking SSE (Secure Service Edge), you need to configure web access policies. This typically involves:

Adding a web category to the SSE configuration that includes Dropbox.

The SSE solution uses category-based filtering to block access to specific applications or services, such as Dropbox, based on their classification.

Other Options:

B. Installing the SSE root certificate is required for enabling SSL inspection, but this does not directly control access to Dropbox.

C and D. Deploying a connector is not necessary for this purpose as the enforcement is done via SSE policies, not by directly interfacing with Dropbox or remote users.

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.

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.

The benefit of the Online Certificate Status Protocol (OCSP) is that it allows a device to query whether a single certificate is revoked or not. OCSP provides a real-time mechanism for checking the revocation status of an individual certificate, enabling devices to verify the validity of certificates quickly and efficiently.

1.Certificate Status Query: OCSP enables devices to send a query to an OCSP responder to check the revocation status of a specific certificate.

2.Real-Time Verification: This protocol offers real-time responses, ensuring that the most up-to-date status of the certificate is obtained.

3.Efficiency: OCSP is more efficient than downloading an entire Certificate Revocation List (CRL), as it only queries the status of one certificate at a time.

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.
