Your Data Guard environment consists of these components and settings: 1. A primary database supporting an OLTP workload
2. A remote physical standby database
3. Real-time query is enabled
4. The redo transport mode is set to SYNC.
5. The protection mode is set to Maximum Availability
Which two are true regarding the DeIayMins Database Property for the standby database?
A.
it can only be enabled for a configuration in Maximum Performance mode.
B.
It allows user errors on the primary to be recovered by using the physical standby database.
C.
It enables you to bypass the default network timeout interval specified for the standby redo transport destination.
D.
it can only be enabled for a configuration in Maximum Availability mode.
E.
It allows logical corruptions on the primary to be recovered by using the physical standby database.
F.
It specifies a delay before the primary ships redo to the standby destination having DeIayMins set.
B,E
BE
B & E
F is wrong, redo will be transfered immediately (it’s in sync) but applied with the delay configured (see https://docs.oracle.com/database/121/DGBKR/dbpropref.htm#DGBKR855)
Please read Footnote 3 in your link
Footnote 3
Although this property is set for the standby database, it is indirectly related to the redo transport services for the database or far sync instance that is sending redo data. The broker propagates the setting you specify on the standby database to the corresponding attributes of the LOG_ARCHIVE_DEST_n value of the database or far sync instance that is sending redo data.
B, F
The DelayMins configurable database property to specify the number of minutes that log apply services must wait before applying redo data to the standby database. Although this property is set for the standby database, it is indirectly related to the redo transport services for the database or far sync instance that is sending redo data. The broker propagates the setting you specify on the standby database to the corresponding attributes of the LOG_ARCHIVE_DEST_n value of the database or far sync instance that is sending redo data.
DelayMins specifies the number of minutes the MRP wait to Apply, but the redo Info has already been sent.
