Question

A(n) shared lock prevents other users from obtaining another shared lock on the same table.

A) True
B) False

Answer 1

The statement is False. A shared lock allows multiple users to concurrently read from the same table and does not prevent others from obtaining another shared lock.

Step-by-step explanation:

The statement that a shared lock prevents other users from obtaining another shared lock on the same table is False. In database systems, a shared lock allows multiple users to read from the same table simultaneously without any issues. The purpose of a shared lock is to ensure that no other transactions can modify the locked data while it's being read, thus maintaining data consistency. However, it does not prevent other users from obtaining another shared lock. These other users can also read from the table concurrently. The lock that prevents others from reading or writing is known as an exclusive lock, not a shared lock.
