Which two statements are true about setting the FAST_START_MTTR_TARGETparameter to a nonzero value?
Correct Answer: A,C
Explanation/Reference: Explanation: The FAST_START_MTTR_TARGET initialization parameter lets you specify in seconds the expected "mean time to recover" (MTTR), which is the expected amount of time Oracle takes to perform crash or instance recovery for a single instance. To enable MTTR advisory, set the initialization parameter FAST_START_MTTR_TARGET to a nonzero value. If FAST_START_MTTR_TARGET is not specified, then MTTR advisory will be OFF. When specified, FAST_START_MTTR_TARGET is overridden by LOG_CHECKPOINT_INTERVAL. Note: The default value is 0. Range of values is 0 to 3600 seconds.
