Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 13

Which three factors can influence the rate of redo apply on a physical standby database?

Answer options

• A. the network latency between the primary and standby databases
• B. the number of archiver processes on the standby database
• C. the number and size of standby redo logs on the primary database
• D. the rate of redo generation on the primary database
• E. the number and size of standby redo logs on the standby database

Correct answer: A, B, E

Explanation

The correct answers are A, B, and E because network latency affects the speed at which data is transmitted, archiver processes determine how quickly redo logs are processed, and the size and number of standby redo logs on the standby database impact its ability to handle incoming redo data efficiently. Options C and D are not correct as they pertain to the primary database rather than factors influencing the standby database's redo apply rate.
