Oracle 1Z0-908 Sample Questions:

01. Your organization uses MySQL Enterprise Monitor, and you are explaining the purpose of its Advisors to a new team member.
Which description is accurate?
a) Advisors enforce row-level and column-level access control on the monitored schemas.
b) Advisors automatically rewrite or re-hint poorly performing SQL statements before they execute.
c) Advisors evaluate collected metrics against best-practice rules and raise alerts or recommendations.
d) Advisors replace the binary log as the mechanism used for point-in-time recovery and backup.
 
02. A single InnoDB table must be recovered from last night's backup and reloaded into an otherwise-healthy running server, without disturbing the rest of the database.
Which two considerations are correct for this partial, single-table restore?
(Choose two.)
a) MySQL Enterprise Backup recovers a file-per-table table through transportable-tablespace import of its .ibd.
b) The table must use innodb_file_per_table so it occupies its own tablespace.
c) Recovering one table from a full physical backup requires overwriting the entire data directory.
d) A single table can never be restored from a mysqldump logical backup.
e) Restoring one table always requires shutting the whole server down first.
 
03. You are estimating how much disk a table occupies, including its secondary indexes, for capacity planning.
Which two columns of information_schema.TABLES should you add together?
a) MAX_DATA_LENGTH + INDEX_LENGTH
b) TABLE_ROWS + AVG_ROW_LENGTH
c) DATA_LENGTH + DATA_FREE
d) DATA_LENGTH + INDEX_LENGTH
 
04. MySQL 8.0 introduced dynamic privileges alongside the traditional static ones.
Which two statements about dynamic privileges are correct?
(Choose two.)
a) They can be granted only at the column level within a single database.
b) A privilege like BACKUP_ADMIN grants one narrow capability rather than the broad SUPER privilege.
c) They are registered at runtime by the server or a loadable component.
d) They are recorded in mysql.tables_priv or mysql.columns_priv rather than mysql.global_grants.
 
05. After creating an InnoDB Cluster, an administrator runs mysqlrouter --bootstrap against a cluster member. The application connects through the Router and the team expects writes to reach the primary and reads to be distributed to secondaries.
Which statement correctly describes how MySQL Router provides this behavior?
a) Bootstrapping writes a configuration with separate read/write and read-only ports, and the application picks the port for each connection.
b) Router requires the application to issue SET ROLE before each query so it knows which member to use.
c) Router promotes a secondary to primary during bootstrap so the read/write port has a dedicated server.
d) Bootstrapping merges reads and writes onto one port, and Router inspects each SQL statement to classify it as a read or a write.
 
06. A DBA backs up an InnoDB-only database with mysqldump --single-transaction while application traffic continues.
Which two statements accurately describe what this option guarantees and where it falls short?
(Choose two.)
a) It locks every table with FLUSH TABLES WITH READ LOCK for the whole dump.
b) It gives InnoDB tables a transaction-consistent snapshot without blocking writes.
c) It extends the same transaction-consistent snapshot to MyISAM tables too.
d) Concurrent DDL during the dump can still compromise the backup's consistency.
e) It works only when the affected tables use the MEMORY storage engine.
 
07. At 14:07 today a developer ran an unqualified DELETE that wiped a critical table.
The most recent full physical backup completed at 02:00, and binary logging has run continuously since. The team knows the approximate time of the bad statement.
Which approach restores the data to the state just before the destructive DELETE?
a) Replay every binary log from position 4 directly onto the live production server without restoring the 02:00 backup first.
b) Restore the 02:00 full backup, then replay all binary logs through to the current time, including the one holding the DELETE.
c) Issue FLUSH BINARY LOGS and PURGE BINARY LOGS to discard the statement while leaving the current data in place.
d) Restore the 02:00 full backup, then replay the binary logs with mysqlbinlog using --stop-datetime to stop just before 14:07.
 
08. A production server hosts a large InnoDB dataset that must remain available for writes at all times.
The DBA needs a full physical backup taken while the server keeps running.
Which tool performs a hot physical backup for this workload?
a) MySQL Enterprise Backup (mysqlbackup)
b) A cold file copy of the data directory
c) mysqlpump
d) mysqldump
 
09. Which statement best describes how a MySQL 8.0 server process is typically started and stopped?
a) Stopping the server requires manually deleting its socket file or PID file.
b) The server can only be started by launching the mysql client and issuing a START SERVER statement.
c) The mysqld server is normally managed through a service manager or startup wrapper.
d) The mysqld process starts automatically when a client connects and stops when the last client disconnects.
 
10. Before performing an in-place upgrade of a MySQL 8.0 server, a DBA wants to identify configuration and schema issues that could cause the upgrade to fail.
Which action best accomplishes this pre-upgrade check?
a) Execute SET PERSIST validate_upgrade=ON so the server checks itself on the next restart.
b) Restore a full backup onto the new server version and observe whether it starts.
c) Enable super_read_only so the server validates schema compatibility automatically.
d) Run the MySQL Shell upgrade checker (util.checkForServerUpgrade()) against the server.
