Oracle MySQL 8.0 Database Administrator 1z0-908 Exam Dumps: Updated Questions & Answers (November 2025)

MySQL TDE uses an appropriate keyring plugin to store the keys in a centralized location.

Both MyISAM and InnoDB tables can be encrypted by setting the keyring_engine = ALL variable in the MySQL configuration file.

Lost tablespace encryption keys can be regenerated only if the master database key is known or present in the Key Vault specification.

TDE can encrypt InnoDB and MyISAM tables only when the tables are stored in the SYSTEM tablespace.

You use the MyISAM storage engine for most common tables.

You use the InnoDB storage engine and statements wait while data is inserted.

The Innodb Buffer pool is full.

Your table accesses wait for the operating system level flush.

The master is most probably too busy to transmit data and the slave needs to wait for more data.

One or more large tables do not have primary keys.

This value shows only I/O latency and is not indicative of the size of the transaction queue.

The master is producing a large volume of events in parallel but the slave is processing them serially.

The parallel slave threads are experiencing lock contention.

ALTER TABLE t1 ADD ENCRYPTED_TABLESPACE = 'Y';

ALTER TABLE t1 ENCRYPTION='Y';

ALTER TABLE t1 WITH ENCRYPTION USING MASTER KEY;

ALTER TABLE t1 SET TDE = 'ON';

Users could overwrite configuration files.

Data files could be deleted.

SQL injections could be used to insert bad data into the database.

MySQL binaries could be damaged, deleted, or altered.

Extra startup time would be required for the MySQL server to reset the privileges.

Replication can use only TCP/IP connections.

Any instance can have multiple slaves, but it can have only one master.

Each instance in a replication topology must have a unique server ID.

Binary logs contain only transactions originating from a single MySQL instance.

Each slave must have its own MySQL user for replication.

Binary logging must be enabled on the master in order to replicate to other instances.

A replication user must have the SELECT privilege for all tables that need to be replicated.

Remove the redo logs. Replace the MySQL binaries with the 5.7.28 binaries. Prepare the tables for upgrade. Upgrade to 8.0.18 again.

Execute: mysqlcheck --check-upgrade mysql columns_priv event proc proxies_priv tables_priv.

Start mysqld again using the --upgrade=FORCE option.

Execute: mysqlcheck --repair mysql columns_priv event proc proxies_priv tables_priv.

Go to the /mysql directory and execute: myisamchk --update-state columns_priv event proc proxies_priv tables_priv.

The lock is at the metadata object level.

The lock is a shared lock.

The lock is an intentional lock.

The lock is at the table object level.

The lock is a row-level lock.

The lock is an exclusive lock.
