HP HPE7-A02 Exam With Confidence Using Practice Dumps

When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA-signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in the cluster and provides a trusted certificate for client connections.

1.HTTPS Security: A CA-signed certificate for HTTPS ensures that all web-based communication to and from the ClearPass server is encrypted and secure.

2.Cluster Communication: Secure communication between ClearPass nodes in the cluster is essential for synchronization and data integrity.

3.Client Trust: Clients accessing the ClearPass server will trust the CA-signed certificate, avoiding security warnings and ensuring smooth operations.

What is Zero Trust Security?

Zero Trust Security is a security model that operates on the principle of "never trust, always verify."

It focuses on securing resources (data, applications, systems) and continuously verifying the identity and trust level of users and devices, regardless of whether they are inside or outside the network.

The primary aim is to reduce reliance on perimeter defenses and implement granular access controls to protect individual resources.

Analysis of Each Option

A. Companies must apply the same access controls to all users, regardless of identity:

Incorrect:

Zero Trust enforces dynamic and identity-based access controls, not the same static controls for everyone.

Users and devices are granted access based on their specific context, role, and trust level.

B. Companies that support remote workers cannot achieve zero trust security and must determine if the benefits outweigh the cost:

Incorrect:

Zero Trust is particularly effective for securing remote work environments by verifying and authenticating remote users and devices before granting access to resources.

The model is adaptable to hybrid and remote work scenarios, making this statement false.

C. Companies should focus on protecting their resources rather than on protecting the boundaries of their internal network:

Correct:

Zero Trust shifts the focus from perimeter security (traditional network boundaries) to protecting specific resources.

This includes implementing measures such as:

Micro-segmentation.

Continuous monitoring of user and device trust levels.

Dynamic access control policies.

The emphasis is on securing sensitive assets rather than assuming an internal network is inherently safe.

D. Companies can achieve zero trust security by strengthening their perimeter security to detect a wider range of threats:

Incorrect:

Zero Trust challenges the traditional reliance on perimeter defenses (firewalls, VPNs) as the sole security mechanism.

Strengthening perimeter security is not sufficient for Zero Trust, as this model assumes threats can already exist inside the network.

Final Explanation

Zero Trust Security emphasizes protecting resources at the granular level rather than relying on the traditional security perimeter, which makes C the most accurate description.

Comprehensive Detailed Explanation

In a user-based tunneling (UBT) setup with reserved VLAN mode, VLAN 64 is used for routing traffic at the gateways. Since the IoT traffic is tunneled to the AOS-10 gateway:

On the gateways:

VLAN 64 must be configured in the iot-wired role for routing purposes.

On the switches:

VLAN 64 does not need to be configured on the access switch physical uplinks because the IoT traffic is tunneled directly to the gateway and does not rely on VLAN configurations at the access layer switches.

Reserved VLAN mode:

Ensures that traffic is encapsulated within the UBT tunnel, and VLANs like 64 are only relevant at the gateway for routing and enforcement.

Therefore, the correct configuration is to define VLAN 64 in the iot-wired role on the AOS-10 gateways and not on any physical interfaces.
