200-301 Question 2
Select 3A network engineer is designing a small office network. The network needs to connect multiple devices, ensure data can be forwarded between different subnets, and provide access to external websites. Which combination of network components is required to achieve this functionality?
- A
Switch
- B
Router
- C
Firewall
- D
Access Point
- E
Hub
Show answer and explanation
Correct answers: A, B, C
Explanation
To achieve the stated requirements, a switch is needed to connect multiple devices within the local network, a router is required to handle inter-network communication and provide internet access, and a firewall ensures secure access to the internet. An access point would only be necessary if wireless connectivity is required, and a hub is not suitable for modern network scenarios.
- A. Correct.
Switches are essential to connect multiple devices within the same network and forward traffic based on MAC addresses.
- B. Correct.
Routers are required to forward data between different networks or subnets and provide connectivity to external networks such as the internet.
- C. Correct.
Firewalls provide security by controlling incoming and outgoing network traffic based on predefined rules, ensuring secure access to external websites.
- D. Incorrect.
Access points are used to provide wireless connectivity, but they are not essential for the described scenario unless wireless devices need to connect.
- E. Incorrect.
Hubs are outdated devices that simply broadcast data to all connected devices, making them inefficient for modern network designs.
