Answer: A

Explanation:

Understanding ACLs:

Access Control Lists (ACLs): A set of rules used to control network traffic and restrict access to network resources by filtering packets based on IP addresses, protocols, or ports.

Implementing Security Zones:

Defining Zones: ACLs can be used to create security zones by applying specific rules to different departments, ensuring that only authorized traffic is allowed between these zones.

Control Traffic: ACLs control inbound and outbound traffic at network boundaries, enforcing security

policies and preventing unauthorized access.

Comparison with Other Options:

Port Security: Limits the number of devices that can connect to a switch port, preventing MAC address flooding attacks, but not used for defining security zones.

Content Filtering: Blocks or allows access to specific content based on predefined policies, typically used for web filtering rather than network segmentation.

NAC (Network Access Control): Controls access to the network based on the security posture of

devices but does not define security zones.

Implementation Steps:

Define ACL rules based on the requirements of each department.

Apply these rules to the appropriate network interfaces or firewall policies to segment the network

into security zones.
