Question 1

A medium-sized company is planning to open a new office that requires a stable and high-speed network connection. What type of cable would you recommend?

Correct Answer: Cat 6a Ethernet Cable

For a medium-sized company opening a new office that requires a stable and high-speed network connection, Cat 6a Ethernet cable is the best choice. Cat 6a offers faster data transfer speeds (up to 10 Gbps) and can support longer cable runs compared to older categories like Cat 5 and Cat 5e. It also provides better crosstalk resistance and noise reduction, ensuring a more stable connection. Coaxial cable is not suitable for modern Ethernet networks and is typically used for cable television or internet service provider connections.

Question 2

Your client's network experiences intermittent connectivity issues. All cables and network devices appear to be working correctly. What could be causing the problem?

Correct Answer: Electromagnetic interference

Electromagnetic interference (EMI) is the most likely cause of intermittent connectivity issues when all cables and network devices appear to be working correctly. EMI can disrupt network signals, leading to temporary loss of connectivity or reduced performance. Low bandwidth would result in consistently slow speeds rather than intermittent issues. A faulty switch or too many network devices would typically cause more persistent problems, not intermittent ones, if all devices appear to be functioning properly.

Question 3

A small business is experiencing slow network speeds and frequent disconnections. What should you do to improve the network?

Correct Answer: Replace the hub with a switch

Hubs can lead to slow network speeds and disconnections, as they transmit data packets to all devices. Replacing a hub with a switch minimizes collisions and improves the network's efficiency, reducing the chances of the stated issues.
