Managing the Redo Transport Services

Which THREE statements about Far Sync instances are correct?

Choose three
  • A They use an spfile, a standby controlfile, and standby redo logs.
  • B A primary database can ship redo directly to multiple Far Sync instances.
  • C They enable standby databases to be configured at remote distances from the primary without impacting performance on the primary.
  • D The Data Guard Broker must be used to deploy and manage Far Sync instances.
  • E They work with any protection level.
Explanation

A Far Sync instance maintains an SPFILE, a control file, and standby redo logs. A primary database can send redo to multiple configured Far Sync destinations. By placing a Far Sync instance near the primary, synchronous transport is limited to the short link; the instance forwards redo asynchronously to remote terminal standbys, avoiding the primary database’s direct long-distance transport overhead. Far Sync is supported in Maximum Performance and Maximum Availability modes, and Data Guard Broker is not mandatory for its deployment or management.
