Discussion
With SQL Server pessimistic locking, no lock is obtained until the user updates the data.
Answer: B
Correct answer: False
That describes optimistic concurrency. Pessimistic locking is the opposite assumption: a lock is taken when the row is read and held while the application works on it, so no one else can change it in the meantime. The two names describe the assumption made about how likely conflict is.
