Q6Single choice
Which statement is true about High Availability (HA) in an Exadata environment?
A
When a standby database is in place, DB_BLOCK_CHECKING is not required and thus is not recommended.
B
The checksums that are performed on the Exadata Storage Server ensure logical consistency of the block content.
C
Stretched RAC is the best alternative for Exadata that combines both HA and DR into one.
D
Due to the different architecture that Exadata has with storage servers when compared to regular Storage Area Network, DB_LOST_WRITE_PROTECT need not be set.
E
The Oracle Exadata Storage Server Software HARD checks operate transparently after enabling DB_BLOCK_CHECKSUM on a database.
