QUESTION 14
You have semi-synchronous replication configured and working with one slave.
rpl_semi_sync_master_timeout has never been reached.
You find that the disk system on the master has failed and as a result, the data on the master is completely unrecoverable.
Which two statements are true? (Choose two.)

No committed transactions are lost.

The slave automatically identifies that the master is unreachable and performs any required actions so that applications can start using the slave as the new master.

As soon as the incident happens, application can read data from the slave and rely on it to return a full and current set of data.

Reads from the slave can return outdated data until the value of the rpi_semi_sync_master_timeout variable is reached.

Reads from the slave can return outdated data for some time, until it applies all transactions from its relay log.

A small amount of committed transactions may be lost in case they were committed just before the disk failure.

QUESTION 15

The cluster has built-in high availability and updates group_replication_ip_whitelistto remove the unreachable nodes.

The group replication will buffer the transactions on the online nodes until the unreachable nodes return online.

A manual intervention to force group members to be only the working two instances is required.

QUESTION 19
