Show answer and explanation
Correct answers: A, C
Explanation
The router is responsible for forwarding traffic between different networks, while the firewall is used to secure network boundaries. Switches, access points, and hubs have their own specialized roles but do not fulfill these specific functions.
- A. Correct.
Routers are responsible for forwarding traffic between different networks, making them essential for inter-network communication.
- B. Incorrect.
Switches operate at Layer 2 (Data Link Layer) and are primarily used to forward traffic within the same network, not between different networks.
- C. Correct.
Firewalls are network security devices designed to secure network boundaries by controlling incoming and outgoing traffic based on predefined rules.
- D. Incorrect.
Wireless Access Points allow wireless devices to connect to the network but do not handle inter-network traffic or secure network boundaries.
- E. Incorrect.
Hubs are outdated devices that simply repeat traffic to all connected devices and do not handle inter-network communication or security.
