Which 2 things should you investigate?

B. Check the rate of change in the statis value Qcache_hits and compare that to the rate of change of
Qcache_not_cached.
C. Check the difference between the InnoDB status values "Log Sequence number" and "Last
Checkpoint" positions then compare that to the total size of the redo log.
D. Check the difference between the InooDB status values "Trx id counter" and "Purge done for" and compare to the state substatus of the main "Main thread"

QUESTION NO: 4
Consider the CHECK TABLE command.
In which two situations should this command be used? (Choose two.)
A. to repair table structure problem
B. to make sure a table has no structural problems
C. to find out why a query takes a long time to execute on a given table
D. to improve performance by updating index distributing statistics on InnoDB tables
E. to make sure that no table indexes are corrupted
Answer: B,E
Explanation
The CHECK TABLE statement performs an integrity check on table structure and contents. It works for
MyISAM and InnoDB tables. For MyISAM tables, it also updates the index statistics. If the table is a view, CHECK TABLE verifies the view definition. If the output from CHECK TABLE indicates that a table has problems, the table should be repaired.
