Which of the following is a benefit of using MySQL Enterprise Backup compared to mysqldump?
A. Ability to perform backups with the database running
B. Automatic replication setup
C. Built-in database schema validation
D. Increased query execution speed

What is the main limitation of asynchronous replication in MySQL?
A. It requires all replicas to acknowledge each transaction
B. It has a higher latency than synchronous replication
C. It only works with InnoDB tables
D. It can result in data loss if the primary server crashes before the replicas receive the changes
正解：D
解説：
The primary limitation of asynchronous replication is the potential for data loss. If the primary server crashes before the replicas have received the changes, those changes may be lost.

Which option allows MySQL Enterprise Backup to encrypt backup data for security purposes?
A. --apply-log
B. --backup-encryption
C. --encrypt

Which MySQL datatype would you use to store a fixed-point decimal number, such as currency amounts?
A. DOUBLE
B. FLOAT
C. DECIMAL
D. INT
正解：C
解説：
DECIMAL is the best choice for storing exact fixed-point numbers, such as currency, because it does not lose precision, unlike floating-point datatypes like FLOAT and DOUBLE.
質問 # 227
Which replication configuration would you use for disaster recovery by keeping a real-time copy of the primary server at a remote location?
A. Multi-source replication
B. Multi-primary replication
C. Primary-replica replication
D. Circular replication
正解：C
解説：
Primary-replica replication is commonly used for disaster recovery, where a replica server at a remote location maintains a real-time copy of the primary server's data. This allows the replica to take over in case the primary server fails.
