Oracle MySQL 8.0 Database Administrator Sample Questions:
Which statement is true about MySQL Enterprise Transparent Data Encryption (TDE)?
- A. Lost tablespace encryption keys can be regenerated only if the master database key is known or present in the Key Vault specification.
- B. MySQL TDE uses an appropriate keyring plugin to store the keys in a centralized location.
- C. Both MyISAM and InnoDB tables can be encrypted by setting the keyring_engine = ALL variable in the MySQL configuration file.
- D. TDE can encrypt InnoDB and MyISAM tables only when the tables are stored in the SYSTEM tablespace.
Correct Answer: A 🗳️
You have configured GTID-based asynchronous replication with one master and one slave.
A user accidentally updated some data on the slave.
To fix this, you stopped replication and successfully reverted the accidental changes. Examine the current GTID information:
You must fix GTID sets on the slave to avoid replicating unwanted transactions in case of failover. Which set of actions would allow the slave to continue replicating without erroneous transactions?
- A. SET GLOBAL gtid_purged=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-2312,bbbbbbbb- bbbb-bbbb-bbbb-bbbbbbbbbbbb:1-9; SET GLOBAL gtid_executed=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-10167;
- B. RESET SLAVE;
SET GLOBAL gtid_purged=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-10167; - C. RESET MASTER;
SET GLOBAL gtid_purged=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-10167; - D. RESET MASTER;
SET GLOBAL gtid_purged-aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-2312;
SET GLOBAL gtid_executed=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-10167; - E. RESET SLAVE;
SET GLOBAL gtid_purged=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-3820;
SET GLOBAL gtid_executed=aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:1-10300;

Which two statements are true about using backups of the binary log? (Choose two.)
- A. They allow for point-in-time recovery of the data.
- B. Binary logs are relatively small, and therefore, excellent for long-term storage and disaster recovery.
- C. Binary logs can always be used to unapply unwanted schema changes.
- D. Multiple binary logs can be used to restore data.
- E. Multiple binary logs can be applied in parallel for faster data restoration.
Correct Answer: A,C 🗳️
Which statement is true about InnoDB persistent index statistics?
- A. Index statistics are calculated from pages buffered in the buffer pool for tables with InnoDB storage engine.
- B. Updating index statistics is an I/O expensive operation.
- C. Tables are scanned and index statistics recalculated when an instance is restarted.
- D. Execution plans based on transient index statistics improve precision when innodb_stats_persistent_sample_pages is increased.
- E. Increasing innodb_stats_persistent_sample_pages determines higher pages scanning speed, at the cost of increased memory usage.
- F. Setting innodb_stats_auto_recalc=ON causes statistics to be updated automatically when a new index is created.
Correct Answer: D 🗳️
