Question 1

A company has implemented NAC to prevent unauthorized access to their network. An employee tries to connect a personal device to the network but fails. What could be the most likely reason?

The employee forgot their password. The personal device does not meet the security requirements. There is a lack of available IP addresses. The network cable is broken.

Correct Answer: The personal device does not meet the security requirements.

Network Access Control checks for compliance with security policies on every device before granting access. In this case, the employee's personal device likely fails to meet the established security requirements and is thus denied access.

Question 2

A coffee shop's wireless network has been frequently attacked by hackers. The owner wants to prevent unauthorized access. What should the security team implement?

Apply WPA2-Enterprise Use Hidden Networks Enable WPS Disable DHCP

Correct Answer: Apply WPA2-Enterprise

Applying WPA2-Enterprise provides strong encryption and authentication, preventing unauthorized access. Enabling WPS is less secure, disabling DHCP and implementing static IP addresses might complicate the connection process for customers, while using hidden networks and enabling MAC address filtering can still be bypassed by skilled hackers.

Question 3

A business is experiencing a series of vicious malware outbreaks. Most of the infections started within the email system. What Endpoint Security solution should be implemented to mitigate this risk?

Mobile Device Management (MDM) Email Security Gateway Endpoint Encryption Intrusion Detection System (IDS)

Correct Answer: Email Security Gateway

Email Security Gateway is a solution that scans incoming emails for malicious content and prevents them from reaching the recipients' mailboxes, thus reducing the risk of malware outbreaks initiated via email.
