Answer 1

1. Layout 1

2. The most suitable place / building to house the server of this organization would be building Research Lab, as this building contains the maximum number of computers.

3. Since the cabling distance between Accounts to Store is quite large, so a repeater would ideally be needed along their path to avoid loss of signals during the course of data flow in this route.

4. Firewall.

5.
