第 94 号 Which MySQL feature helps to analyze real-time query performance and pinpoint bottlenecks?

MySQL Binary Logs

MySQL Enterprise Audit

MySQL Performance Schema

MySQL Replication

MySQL Performance Schema is designed to analyze and monitor real-time query performance, identify bottlenecks, and provide detailed statistics about server operations.

NO.95 What is the main advantage of MySQL InnoDB Cluster over traditional asynchronous replication for high availability?

It offers better performance in query execution

It guarantees that all replicas have the same data before committing transactions

It is more suitable for read-heavy workloads

It reduces the cost of storage

MySQL InnoDB Cluster ensures that all replicas are in sync before committing transactions, offering better data consistency than traditional asynchronous replication, where replicas might lag behind the primary server.

第 96 号 Which of the following is a key feature of the MySQL Community Edition?

MySQL Enterprise Backup

MySQL InnoDB Cluster

MySQL Performance Schema

MySQL Enterprise Audit

MySQL Performance Schema is available in both the Community and Enterprise editions, providing a powerful framework for tracking database performance. Enterprise Backup and Audit are exclusive to the Enterprise Edition.

第 97 号 How can you schedule automated backups of a MySQL database in a Linux environment?

Using the mysqlbackup –schedule command

By configuring the my.cnf file for automated backups

By using cron to schedule backup commands

By running the mysqlbinlog command regularly

Automated backups in a Linux environment are typically scheduled using cron jobs, which allow you to run MySQL backup commands (such as mysqldump or mysqlbackup) at predefined intervals.

NO.98 Which command is used to shut down the MySQL server on a Linux system?

mysql shutdown

systemctl stop mysqld

mysqladmin –stop

service mysql-server shutdown

On most Linux distributions, you can stop the MySQL server using the systemctl stop mysqld command, which sends a shutdown signal to the MySQL service.

NO.99 Which MySQL feature allows an organization to track user activities for regulatory compliance, such as GDPR or HIPAA?

MySQL Query Optimizer

MySQL Enterprise Backup

MySQL Enterprise Audit

MySQL InnoDB Cluster

MySQL Enterprise Audit logs user activities and access to ensure that organizations can track database operations and meet regulatory compliance standards, such as GDPR or HIPAA.

编号 100 What is the primary role of MySQL Enterprise Authentication?

To create backups of MySQL databases

To enforce password policies for users

To integrate MySQL with external authentication systems

To optimize query execution

MySQL Enterprise Authentication allows MySQL to integrate with external authentication systems like LDAP or Active Directory, providing centralized user management and enhancing security.

NO.101 Which command is used to change the definition of a table after it has been created?

MODIFY TABLE

ALTER TABLE

UPDATE TABLE

CHANGE TABLE

The ALTER TABLE command is used to change the structure of an existing table, such as adding or modifying columns or constraints.

编号：102 Which tool can be used to visualize MySQL metrics, such as CPU usage, memory usage, and disk activity?

MySQL Query Optimizer

MySQL Workbench

MySQL Enterprise Monitor

MySQL Replication Dashboard

MySQL Enterprise Monitor provides a graphical interface to visualize MySQL performance metrics, including CPU usage, memory usage, and disk activity, helping administrators proactively manage their database environment.

第 103 号 Which datatype is the best choice for storing binary large objects (BLOBs), such as images or files?

TEXT

ENUM

BLOB

INT

The BLOB datatype is designed to store binary large objects, such as images, audio files, or other multimedia content.

第 104 号 Which column in the mysql.user table defines where a user can connect from?

Host User

密码

Role D.

The Host column in the mysql.user table defines the host or IP address from which the user is allowed to connect to the MySQL server.

第 105 号 Which backup method should you use to capture both the database structure and data for disaster recovery in MySQL?

Binary log backup

Incremental backup

Full backup

Logical backup using mysqldump

A full backup captures both the database structure and all data, providing a complete snapshot of the database at the time of the backup. This is essential for disaster recovery, as it ensures that you can restore the entire database from a single backup.

NO.106 Which type of join returns only the rows where there is a match in both tables?

LEFT JOIN RIGHT

JOIN INNER JOIN

FULL OUTER JOIN D.

An INNER JOIN returns only the rows that have matching values in both tables. If no match is found, the row is excluded from the result set.

第 107 号 Which statement best describes asynchronous replication in MySQL?

The replica is always up to date with the primary

The primary server waits for all replicas to apply changes before committing

The primary server does not wait for the replica to confirm changes before committing

Changes are applied to the replica in real time

In asynchronous replication, the primary server does not wait for the replica to confirm that changes have been applied. This can result in the replica lagging behind the primary in real time.

第 108 号 Which two features are part of MySQL Enterprise Security Tools?

MySQL Enterprise Authentication

MySQL Enterprise Audit

MySQL Performance Schema

MySQL Query Cache

MySQL Enterprise Authentication and MySQL Enterprise Audit are key components of MySQL Enterprise Security Tools. They enhance security by enabling external authentication, logging user activity, and tracking database access.

第 109 号 Which two options are available for configuring backups using MySQL Enterprise Backup?

Full backup

Compressed backup
