Answers provide in-depth explanations - and show why the incorrect choices are wrong,as shown below: Your have a TCP/IP network that uses a single network ID. There are 45 users on this network,and about eight of the users spend most of the day sending files with an average size of 145MB to each other over the network. This is significantly slowing down overall network performance for all users on the network. What would be the most cost-effective solution for solving network performance problems?

A. Install an active hub

B. Install a bridge

C. Enable the scope on the DHCP server

D. implement distance vector routing protocols B. Installing a bridge will allow you topartition the collision domain for users transferring large files. In this way,traffic between users who transfer large files to each other will remain on one side of the bridge. The other users of the network will be located on the opposite side of the bridge,and will not be affected by the file transfers.

A. An Active hub will not partition the collision domain. C and D are incorrect,since the implementation of routing protocols will not improve performance; no routing is taking place within the single subnet.
