Pregunta 1

Examine this statement, which executes successfully: You want to improve the performance of this query: Which change enables the query to succeed while accessing fewer rows?

Pregunta 2

Which three are characteristics of a newly created role? (Choose three.)

Pregunta 3

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?

Pregunta 4

Total system memory is 32G. After profiling the system, you highlight these MySQL status and global variables: The OS metrics indicate that disk is a bottleneck.
