Answer to Question 1

A synchronous distributed database keeps all data constantly up to date across the network. A user at any site can access data anywhere on the network at any time and get the same result. An asynchronous distributed database keeps replicated copies of databases on local servers. In this way, local servers can access data without reaching out across the network.

Answer to Question 2

B
Explanation: B) If you decide that new hardware or system software is a strong possibility, you may want to issue a request for proposal (RFP) to vendors. The RFP will ask the vendors to propose hardware and system software that will meet the requirements of your new system.
