You have installed two 64G flash devices to support the Database Smart Flash Cache feature on your database server that is running on Oracle Linux.
You have set the db_smart_flash_file parameter:
DB_FLASH_CACHE_FILE= ' /dev/f lash_device_1',' /dev/f lash_device_2'
How should the D3_flash_cache_size be configured to use both devices?

• A.Set DB_FLASH_CACHE_SIZE=64G.
• B.Set D3_FLASH_CACHE_SIZE=64G, 64G.
• C.Set D3_FLASK_CACKE_SI2E=i28G.
• D.db_flash_cache_SI2E is automatically configured by the instance at startup.

Your database supports an OLTP workload. Examine the output of the query:
SQL> SSLECT target_mttr, estimated_mttr
FROM v$instance_recovery
Target_mttrestimated_mttr
- --------------------- ---------------------------
0 76
To ensure faster instance recovery, you set the fast_start_mttrjtargh:t initialization parameter to 30.
What is the effect of this setting on the database?

• A.The MTTR advisor is disabled.
• B.Automatic checkpoint tuning is disabled.
• C.The overhead on database performance is increased because of frequent writes to disk.
• D.The frequency of log switches is increased.
