Ensurepass 2018 PDF and VCE

View the Exhibit exhibit2 to examine the plans available in the SQL plan baseline. The baseline in the first row of the Exhibit is created when OPTIMIZER_MODE was set to FIRST_ROWS.

  1. The optimizer uses a new plan because none of the plans in the exhibit2 are fixed plans.

  2. The optimizer uses the plan in the second row of the exhibit2 because it is an accepted plan.

  3. The optimizer uses the plan in the first row of the exhibit2 because it is the latest generated plan.

  4. The optimizer uses the plan in the first row of the exhibit2 because OPTIMIZER_MODE was set to FIRST_ROW during its creation.

Answer: B

  3. It must be a nondefault temporary tablespace for the database.

  4. It can be a default or nondefault temporary tablespace for the database.

  5. It must be the default temporary tablespace of the user who issues the command.

Answer: B,D
