To address frequent locks and slow query performance after a security patch, which processes should the administrator implement? (Select the two best options.)

• A. Implement alternative locking mechanisms
• B. Increase the database size
• C. Implement rolling back problematic patches
• D. Enhance physical security measures

Answer: (A)

Implementing alternative locking mechanisms is a viable approach to address frequent locks and slow query performance. Locking mechanisms play a crucial role in database management by ensuring that multiple transactions can occur without interference. If the current locking system leads to frequent locks, exploring different mechanisms can help improve concurrency and reduce wait times for transactions. For example, using optimistic locking allows transactions to proceed without locking resources until they are ready to commit, which can enhance performance if conflicts are rare.

The correct selection of another option focuses on directly addressing the issue of slow query performance. This could involve optimizing queries, indexing strategies, or altering the locking behavior, rather than merely increasing database size or implementing security patches that may introduce complexity. Enhancing physical security measures, while important, does not address the performance issue at hand, making it a less effective choice in this scenario.
