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 attnbutes SYNC NOAFFIRM to minimize the performance impact on the primary.

DGMGRL > show configuration;
Protection Mode MaxPerformance
dogs-Primary database sheep-Snapshot standby database cats-Snapshot standby database
Fast-Start Failover: DISABLED
Configuration Status: SUCCESS

DGMGDRL> edit configuration set protection mode as max availability;
Error ORA-16627 operation disallowed since no standby databases would remain to support protection mode Failed.

D. DGMGRL> edit database sheep set property LogXptMode= fastsync;
E. DGMGRL> edit database cats set property LogXptMode= sync;

Backups are offloaded to the remote physical standby.

A. Archive logs on the primary database may be deleted once they are applied on all standby databases.
B. Archive logs on the primary database may be deleted once they are shipped on all standby databases.
C. The deletion policy for archive logs on the remote physical standby should be set so that archived logs are deleted once they backed up at least once on the remote physical standby database.
D. The deletion policy for archive logs on the remote physical standby should be set so that archived logs are deleted once they are applied on all standby databases.
E. Archive logs on the primary database may be deleted once they are archived locally to disk.
