- Two Phase lock protocol
- Timestamp based protocol
- Validation based protocol
- Time lock protocol
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Lock-based concurrency control uses locks to manage access to the database.
Two-Phase Locking (2PL) protocol ensures serializability by dividing the transaction into two phases: growing (acquiring locks) and shrinking (releasing locks).
