QUESTION 99
Which index type should be used if you need to perform geospatial searches in MySQL?

BTREE

FULLTEXT

HASH

SPATIAL

SPATIAL indexes are used in MySQL for geospatial data and queries. They support efficient indexing and querying of spatial objects such as points, lines, and polygons.

QUESTION 100
What is the purpose of the binary log in MySQL replication?

To store query results

To store changes made to the database

To cache queries for faster access

To back up data automatically

The binary log records all changes made to the database (such as updates, inserts, and deletes). These logs are used to replicate these changes to the replica servers.

QUESTION 101
Which of the following is a characteristic of MySQL semi-synchronous replication?

The primary server waits for at least one replica to apply the transaction before committing

The primary server waits for at least one replica to acknowledge the receipt of the transaction before committing

The replica server is always in sync with the primary

All replicas must acknowledge the transaction before it is committed

In semi-synchronous replication, the primary server waits for one replica to acknowledge receipt of the transaction before committing, but it does not wait for the replica to apply the transaction.

QUESTION 102
Which of the following features are part of MySQL Enterprise Edition?

MySQL Enterprise Backup

MySQL Shell

MySQL Enterprise Firewall

MySQL Cluster

MySQL Enterprise Backup and MySQL Enterprise Firewall are exclusive to MySQL Enterprise Edition. MySQL Shell and MySQL Cluster are available in both editions. Enterprise Backup provides advanced backup solutions, while the Firewall protects against SQL injection attacks.

QUESTION 103
Which of the following is a valid MySQL replication topology?

Star replication Circular

replication Multi-primary

replication Cross-server

replication

Multi-primary replication (also known as multi-master replication) allows multiple servers to act as both a source and a replica, meaning they can accept updates and replicate changes to each other.

QUESTION 104
What is the default transaction isolation level in MySQL’s InnoDB storage engine?

READ UNCOMMITTED

READ COMMITTED

REPEATABLE READ

SERIALIZABLE

The default transaction isolation level in InnoDB is REPEATABLE READ, which ensures that transactions cannot see changes made by other transactions until they are committed. This level helps to prevent non-repeatable reads and phantom reads.

QUESTION 105
Which MySQL command is used to delete a table from a database?

DROP TABLE

DELETE TABLE

REMOVE TABLE

TRUNCATE TABLE

The DROP TABLE command is used to permanently delete a table and its data from the database.

QUESTION 106
How does MySQL InnoDB Cluster ensure data consistency across all nodes?

By performing asynchronous replication

By using Group Replication with quorum-based voting

By using statement-based replication

By optimizing query execution times

MySQL InnoDB Cluster ensures data consistency through Group Replication with quorum-based voting, where the majority of nodes must agree on a transaction before it is committed. This prevents conflicting data and maintains consistency across the cluster.

QUESTION 107
Which two statements are used to grant privileges to MySQL users?

GRANT

REVOKE

CREATE USER

ALTER USER

The GRANT statement is used to assign privileges to a MySQL user. The ALTER USER statement can also be used to adjust user accounts, but it doesn’t directly grant privileges like GRANT does.

QUESTION 108
What is a logical backup in MySQL?

A backup of the database structure and data as SQL statements

A backup of the binary logs

A backup of the data directory

A backup of the user privileges

A logical backup involves exporting the database structure and data as SQL statements using tools like mysqldump. These backups are portable but can be slower and larger than physical backups.

QUESTION 109
Which MySQL Enterprise Edition feature is useful for online backups of large databases?

MySQL Shell

MySQL Dump

MySQL Enterprise Backup

MySQL Replication

MySQL Enterprise Backup allows for online, non-blocking backups of large databases, making it a valuable tool for enterprises that need to minimize downtime and data loss during backup operations.

QUESTION 110
What is the default replication mode used in MySQL when no specific replication mode is configured?

Synchronous replication

Semi-synchronous replication

Asynchronous replication

Multi-source replication

The default replication mode in MySQL is asynchronous replication, where the primary server commits changes without waiting for confirmation from the replicas.

QUESTION 111
Which of the following actions can MySQL Enterprise Audit log for compliance purposes?

User login attempts

Changes to database schemas

Execution of specific SQL queries

All of the above

MySQL Enterprise Audit logs user activities, including login attempts, schema changes, and SQL query executions, ensuring a detailed audit trail that supports compliance with security standards like GDPR or HIPAA.

QUESTION 112
Which two features are offered by MySQL Enterprise Authentication?

Integration with LDAP for external authentication

Automatic database backups

Support for multi-factor authentication (MFA)

Monitoring database performance

MySQL Enterprise Authentication integrates with external authentication systems such as LDAP and Active Directory and also supports multi-factor authentication (MFA) for enhanced security, ensuring users are authenticated through multiple verification methods.

QUESTION 113
Which MySQL replication mode is most vulnerable to data loss in the event of a primary server crash?

Semi-synchronous replication

Synchronous replication

Asynchronous replication

Multi-source replication

Asynchronous replication is most vulnerable to data loss because the primary server does not wait for the replicas to confirm that they have applied changes. If the primary server crashes, there may be unreplicated transactions.

QUESTION 114
Which of the following SQL commands is blocked by default in MySQL Enterprise Firewall if it detects it as suspicious or unauthorized?

SELECT

INSERT

DROP DATABASE

DESCRIBE

MySQL Enterprise Firewall can block destructive SQL commands, such as DROP DATABASE, if these commands are not part of the normal query patterns learned by the firewall, preventing unauthorized database modification or deletion.
