Aruba Associate Network Security & Access Control

Question 1

What is the primary purpose of a firewall in a network?

Accepted Answer

Filter network traffic

Answer

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its primary purpose is to establish a barrier between a trusted internal network and untrusted external networks, like the internet, preventing unauthorized access and malicious activity. It acts as a filter to protect network resources.

Question 2

Which protocol is commonly used to secure remote network access?

Accepted Answer

IPSec

Answer

IPSec (Internet Protocol Security) is a suite of protocols used to secure IP communications by authenticating and encrypting each IP packet of a communication session. It is commonly used to create Virtual Private Networks (VPNs), providing secure remote access to corporate networks over untrusted networks like the internet. This ensures data confidentiality and integrity.

Question 3

What does Role-Based Access Control (RBAC) do?

Accepted Answer

Manages access based on user roles

Answer

Role-Based Access Control (RBAC) is a method of restricting network access based on the roles of individual users within an organization. Instead of assigning permissions directly to users, permissions are assigned to specific roles, and users are then assigned to those roles. This simplifies management and ensures users only have access to the resources necessary for their job functions.

Question 4

Which Aruba solution helps enforce network access policies?

Accepted Answer

ClearPass

Answer

Aruba ClearPass is a comprehensive Network Access Control (NAC) solution that plays a critical role in enforcing network access policies. It authenticates users and devices, assesses their security posture, and then applies granular policies to determine what network resources they can access. This ensures compliance and security across wired and wireless networks.

Question 5

Which method improves wireless network security?

Accepted Answer

WPA3

Answer

WPA3 (Wi-Fi Protected Access 3) is the latest and most secure encryption standard for wireless networks, offering significant improvements over its predecessors like WPA and WPA2. It provides stronger encryption, enhanced protection against brute-force attacks, and individualized data encryption in public Wi-Fi networks. This makes it the best choice for improving wireless network security.
