Q141. Which MySQL replication topology is best suited for geographically distributed databases?

Multi-source replication

Primary-replica replication

Group replication

Circular replication

Multi-source replication allows a single replica to receive updates from multiple primary servers, which can be located in different geographic regions. This topology is useful for geographically distributed databases.

Q142. What is the maximum length of a VARCHAR column in MySQL?

255 characters

65,535 characters

32,767 characters

1,000 characters

The VARCHAR datatype can store up to 65,535 characters. This limit depends on the maximum row size and the character set used.

Q143. Which MySQL Enterprise Edition feature allows you to track database activity in order to meet compliance requirements?

MySQL Enterprise Firewall

MySQL Enterprise Monitor

MySQL Enterprise Audit

MySQL Enterprise Backup

MySQL Enterprise Audit helps organizations track database activities and maintain compliance with regulations such as GDPR or HIPAA by logging user access and changes to the database.

Q144. How would you allow a user to connect from any host in MySQL?

Grant privileges with ‘user’@’localhost’

Grant privileges with ‘user’@’%’

Grant privileges with ‘user’@’all_hosts’

Grant privileges with ‘user’@’*.*’

The @’%’ in MySQL user creation allows a user to connect from any host. This is often used when users need to connect from multiple different servers.

Q145. What does the mysqlbackup –backup-dir option specify?

The directory where the logs will be stored

The directory where the binary logs will be stored

The directory where the backup will be stored

The directory where the database will be restored

The –backup-dir option in the mysqlbackup command specifies the directory where the backup files will be stored during the backup process.

Q146. Which MySQL Enterprise Edition feature helps to enforce user privileges?

MySQL Role-Based Access Control

MySQL Enterprise Monitor MySQL

Enterprise Backup MySQL Query

Cache

MySQL Role-Based Access Control (RBAC) allows for fine-grained control over user privileges, making it easier to manage database security and restrict access to specific actions within the database.

Q147. What type of tool is MySQL Enterprise Audit?

Monitoring tool for performance

Security tool for tracking user actions

Backup tool for managing database dumps

Replication tool for master-slave databases

MySQL Enterprise Audit is designed to track and log database activities, making it easier to detect unauthorized actions and comply with regulatory requirements for data access and modifications.

Q148. Which of the following is a key benefit of using MySQL Enterprise Firewall?

Improved query performance

Real-time SQL injection protection

Automatic schema validation

Data replication optimization

One of the key benefits of using MySQL Enterprise Firewall is its ability to provide real-time protection against SQL injection by monitoring and blocking potentially harmful queries based on learned patterns of legitimate activity.

Q149. Which MySQL log should be enabled to monitor failed connection attempts?

Slow Query Log

General Query Log

Error Log

Relay Log

The Error Log captures failed connection attempts, server start-up messages, and other critical errors, providing insights into potential security issues or configuration problems.

Q150. What does the SUPER privilege in MySQL allow a user to do?

Modify table structures

Manage user roles

Perform administrative tasks like shutting down the server

Grant privileges to other users

The SUPER privilege in MySQL allows users to perform advanced administrative tasks such as starting or stopping the MySQL server, killing running queries, and modifying system variables. It is a powerful privilege that is often reserved for database administrators.

Q151. Which two commands can be used to restore a MySQL database from a backup?

mysql –restore

mysql < backup.sql

mysqlbackup –apply-log

mysql –start-replication

The mysql < backup.sql command is used to restore a database from a logical backup created by mysqldump. The mysqlbackup command with the –apply-log option is used to prepare a physical backup for restoration.

Q152. Which replication topology is best suited for consolidating data from multiple sources into a single replica?

Multi-primary replication

Circular replication

Multi-source replication

Group replication

Multi-source replication allows a single replica to receive data from multiple primary servers. This is ideal for consolidating data from various sources into a single, unified replica.

Q153. Which MySQL security tool provides real-time blocking of suspicious SQL queries to protect against attacks?

MySQL Enterprise Backup

MySQL Enterprise Authentication

MySQL Enterprise Audit

MySQL Enterprise Firewall

MySQL Enterprise Firewall provides real-time blocking of suspicious SQL queries by learning allowed query patterns and detecting deviations from those patterns. This capability is crucial for protecting the database against SQL injection and other malicious query-based attacks.

Q154. In MySQL Group Replication, what happens when a primary server fails?

The replica continues serving traffic

The failed primary server is automatically replaced by another server

All transactions are rolled back

Replication stops until the primary is restored

In MySQL Group Replication, if the primary server fails, the group automatically selects a new primary server, ensuring continuous availability without manual intervention.

Q155. What is the role of MySQL Enterprise Firewall in preventing SQL injection attacks?

Encrypts SQL queries before execution

Monitors and blocks queries that do not match a predefined safe pattern

Provides an audit trail of all queries executed in the database

Optimizes query performance to avoid slow queries

MySQL Enterprise Firewall prevents SQL injection attacks by monitoring and blocking any queries that do not match known, legitimate SQL patterns. It learns from allowed queries and builds an allowlist for future query validation.

Q156. What does the UNIQUE constraint ensure when applied to a column in a MySQL table?

The column can contain only one specific value

The column cannot contain NULL values

The column values must be unique across all rows

The column cannot be indexed

The UNIQUE constraint ensures that all values in the column are unique across all rows in the table, preventing duplicate entries.

Q157. Which MySQL configuration option is used to disable binary logging?

disable_log_bin

skip-binlog

log-bin=0

skip-log-bin

The skip-log-bin option can be used in the MySQL configuration file (my.cnf) to disable binary logging. Binary logging is used for replication and data recovery, but in some cases, you might want to disable it to avoid extra disk usage.

Q158. Which MySQL index type is optimized for equality comparisons on columns with highly selective values?

BTREE

HASH

FULLTEXT

SPATIAL

HASH indexes are optimized for equality comparisons, meaning they are fast for exact matches. However, they are not suitable for range queries, which is where BTREE indexes perform better.

Q159. What does the –incremental option in mysqlbackup do?

Backs up only the binary logs

Backs up only the database structure

Backs up only the changes since the last backup

Restores the database from a previous backup

The –incremental option in mysqlbackup backs up only the changes made since the last full or incremental backup, allowing for more efficient backup operations.

Q160. Which of the following storage engines does not support transactions in MySQL?

InnoDB

MyISAM

NDB
