B. Move redo logs to /dev/shm to improve their speed.
C. Lower innodb_max_dirty_pages_pct to flush more often.
D. Reduce the size of redo logs to improve storage efficiency.
Question 2

A. a backup created with mysqldump --all-databases
B. a backup created using FLUSH TABLES ... FOR EXPORT
C. a file system-level snapshot
D. a file system copy created while MySQL was shut down.
E. an up-to-date replication slave
Question 3

The MySQL Server is restarted without error.
What effect will the new configuration have on existing account?
A. They are not affected by this configuration change.
B. They all connect via the secure sha256_password algorithm without any configuration change.
C. They will have to change their password the next time they login to the server.

After 30 minutes, you notice that the rate of restore seems to have slowed down. No other processes or external factors are affecting server performance.
Which is the most likely explanation for this slowdown?
A. The MySQL server has stopped inserting data to check index consistency.
B. InnoDB has filled the redo log and now must flush the pages.
C. The MySQL server is taking a periodical snapshot of data so it can resume the restore if it is interrupted mid-way.
