Ensuring bisynchronous capabilities on all transmission lines
Suggested answer: B

Explanation:

The best way to ensure that a proper cutoff has been established to reinstate transactions and records to their condition just prior to a computer system failure is to use a database management system (DBMS) to dynamically back-out partially processed transactions. A DBMS is a software system that manages the creation, manipulation, retrieval, and security of data stored in a database. A DBMS can provide features such as transaction management, concurrency control, recovery management, and integrity management. A DBMS can dynamically back-out partially processed transactions by using mechanisms such as rollback segments, undo logs, or write-ahead logs. These mechanisms allow the DBMS to restore the database to a consistent state before the failure occurred.Reference:
