It terminates

Q63. Which three statements are true about dropping and unused columns in an Oracle database? (Choose three.)

A primary key column referenced by another column as a foreign key can be dropped if using the CASCADE option.

An UNUSED column’s space is reclaimed automatically when the block containing that column is next queried.

An UNUSED column’s space is reclaimed automatically when the row containing that column is next queried.

Partition key columns cannot be dropped.

A DROP COLUMN command can be rolled back

A column that is set to UNUSED still counts towards the limit of 1000 columns per table

Q64. Which three statements are true about undo segments and the use of undo by transactions in an Oracle database instance? (Choose three.)

An undo segment may be used by multiple transactions simultaneously

Undo segments can wrap around to the first extent when a transaction fills the last extend of the undo segment

Undo segments have a minimum of three extents

Undo segments can extend when a transaction fills the last extent of the undo segment

A single transaction may use multiple undo segments simultaneously

Undo segments must be stored in a BIGFILE tablespace

Undo segments must be stored in a SMALLFILE tablespace

Q65. Which two functions are performed by a listener?

creating a user session in the System Global Area (SGA)

verifying the service name in an incoming user request

verifying a user’s authentication credentials
