Which of the following devices is used to implement ACL polices for an environment?
Managed switch
Gateway
Repeater
Firewall
A firewall implements ACLs (Access Control Lists) to filter traffic and enforce policies based on rules such as IP address, port, or protocol.
Why Not A (Managed switch): A managed switch supports VLANs and QoS but does not enforce ACLs at the network perimeter.
Why Not B (Gateway): Gateways connect networks and translate protocols but don’t typically implement ACLs.
Why Not C (Repeater): Repeaters extend signal range but don’t enforce policies.
CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.2, firewall concepts.
