Loss of the database management system (DBMS) can result from

• A. Failure of any computers serving the system or damage to the building housing the data management system.
• B. Interruption of communication links
• C. End office to Tandem Router broken
• D. PSAP destruction

Answer: (A)

The key idea is that the database management system depends on the underlying hardware and the environment that hosts it. If the computers that run the DBMS fail or if the building or data center housing those systems is damaged, the DBMS cannot operate at all. This is a direct, fundamental cause of the system going down because the software needs functioning servers and a usable facility to run, access data, and serve requests. Interruption of communication links can prevent users from reaching the DBMS or degrade access, but the DBMS itself may still be running somewhere and reachable once connectivity is restored. The same logic applies to a broken network path between the end office and a router—it's a connectivity issue, not necessarily the failure of the DBMS itself. Destruction of the PSAP is an extreme scenario that would halt operations in that location, but the direct, root cause of DBMS loss is hardware or hosting-facility damage.
