Which two are true about instance recovery? (Choose two.)

It is not possible if an archived log is missing.

It is performed automatically after the database is opened; however, blocks requiring recovery are not available until they are recovered.

Setting FAST_START_MTTR_TARGET to a lower value reduces instance recovery time by causing dirty buffers to be written to disk more frequently, thereby reducing the number of I/Os needed during instance recovery.

It is performed by the Recovery Writer (RVWR) background process.

Recovery reads redo until the end of the redo thread. SMON rollsback any dead transactions, and then the datanase is opened.

Recovery begins from the last checkpoint position that was recorded in the control file by the checkpoint process (CKPT).
