Your expertise is requested for these customer requirements:
1. The Data Guard environment must be in maximum protection mode.
2. Reports must be offloaded to a physical standby database.
3. There must be no lag between the primary and standby databases that affect the reports produced.
4. The primary database must be resilient in case of a single network failure.
Which solution is correct for these requirements?
A. two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DELAY parameter set to zero, receiving redo from the primary with asynchronous transport
B. two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
C. one physical standby database with Real-Time Query enabled, receiving redo from two Far Sync instances that are connected the primary
D. one physical standby database with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
E. two physical standby databases with Real-Time Query enabled, receiving redo from the primary with the LOG_ARCHIVE_DEST_n attributes SYNC
