Show answer and explanation
Correct answers: A, B, C
Explanation
To set up a functional and secure office network, a switch is needed to connect devices within the local network, a router is required to enable communication with external networks, and a firewall is necessary to protect the network from potential threats. While other components like DNS servers and load balancers have specific roles, they are not critical for the basic functionality described in the scenario.
- A. Correct.
A switch is used to connect devices within the same local network, allowing them to communicate efficiently.
- B. Correct.
A router is essential to route traffic between the local office network and external networks, such as the internet.
- C. Correct.
A firewall is important to secure the network by controlling and monitoring incoming and outgoing traffic based on security rules.
- D. Incorrect.
A DNS server does not allocate IP addresses; this is typically the role of a DHCP server. DNS servers resolve domain names to IP addresses.
- E. Incorrect.
A load balancer is used to distribute traffic across multiple servers, which is not typically required for basic office network functionality.
