Master HPE7-A02 Exam with Reliable Practice Questions

Correct : A

1. Understanding the Role Mapping Evaluation:

Role mapping is set to 'Evaluate: Select first,' meaning the first rule that matches the client attributes will determine the role(s) assigned.

Contractors group: Since the client is in the Contractors group (not Managers), Rule 1 in the Role Mapping Policy does not match.

TEAP-Method-1-Status EQUALS Success: This condition matches Rule 2, so the client is assigned the domain-comp role.

No other rules match, so the default role [Other] is not applied.

2. Resulting Role from Role Mapping Policy:

The client is assigned the domain-comp role.

3. Enforcement Policy Evaluation:

Enforcement policy is also set to 'Evaluate: Select first,' so the first matching rule determines the enforcement profile.

Rule 1 (Tips Role = manager AND domain-comp):

The client only has the domain-comp role, not manager, so this rule does not match.

Rule 2 (Tips Role = manager):

The client does not have the manager role, so this rule does not match.

Rule 3 (Tips Role = domain-comp):

This rule matches the client's role, but it is not evaluated because the enforcement policy already skipped to the default action after failing the first two rules.

4. Default Enforcement Profile:

Since no rule explicitly matches and the policy evaluation stops at the default, the default profile [Deny Access Profile] is applied.

Final Outcome:

The client is denied access because none of the matching rules satisfy the conditions.

Role and Policy Evaluation Logic for ClearPass Authentication Services.

Correct : B

When WPA3 with 802.1X authentication is enforced on an HPE Aruba Networking WLAN, the authentication process strictly adheres to security standards. Here's how the process works:

1. 802.1X Authentication Workflow in WPA3

The client must provide valid credentials (such as certificates or username/password) to authenticate with the RADIUS server via 802.1X.

If the client fails authentication (e.g., due to invalid credentials or lack of proper configuration), the 802.1X handshake fails, and the AP terminates the connection.

2. Role Assignment in WLANs

Default Role: The role assigned to authenticated clients after a successful 802.1X authentication. It is not applied to unauthenticated clients.

Critical Role: This is a fallback role applied when there are issues communicating with the RADIUS server, not when authentication fails.

Initial Role: A temporary role assigned to clients before authentication completes. However, this role is removed once the authentication process determines failure.

3. Behavior Upon Authentication Failure

In the case of an authentication failure, the client does not get assigned to any role (default, critical, or initial) because it does not meet the conditions for network access.

The client is dropped immediately, and no further communication is allowed until reauthentication is attempted.

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

Correct : B

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

Correct : A

When setting up a ClearPass cluster, it is critical to ensure secure communication between the cluster nodes and the client devices. For this purpose, certain certificates must be properly configured.

1. Why HTTPS Requires a CA-Signed Certificate?

HTTPS communication is used for inter-cluster communication and for the web-based user interface that administrators use to manage the ClearPass cluster.

Before joining the cluster, it is strongly recommended to install a CA-signed HTTPS certificate on the Subscriber to ensure secure communication and prevent warnings/errors due to untrusted certificates.

Without a CA-signed certificate, the Subscriber might use a self-signed certificate, leading to security risks and lack of trust validation.

2. Analysis of Other Certificate Types

B . Database:

Incorrect: Database communications within ClearPass clusters are secured using internal certificates or keys. These are not user-facing and do not require a CA-signed certificate before joining the cluster.

C . RADIUS/EAP:

Incorrect: RADIUS/EAP certificates are important for client authentication, but they are not required on the Subscriber prior to cluster joining. These can be configured after the Subscriber is part of the cluster.

D . RadSec:

Incorrect: RadSec is an optional feature for secure RADIUS communication over TLS, and its certificate configuration is typically performed post-cluster setup.

Final Recommendation

To ensure secure cluster operations and seamless web-based management, a CA-signed HTTPS certificate should be installed on the Subscriber before it joins the ClearPass cluster.
