Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 1

Which two statements are true for Data Guard environments with multi-tenant databases?

Answer options

• A. DB_UNIQUE_NAME must be specified differently for each pluggable database within a multi-tenant standby database.
• B. Each pluggable database within a multi-tenant physical standby database has a minimum of one associated Oracle Net service name.
• C. Each pluggable database within a multi-tenant physical standby has one MRP background process running during redo apply.
• D. A pluggable database within a multi-tenant standby database can have a different open mode than the container database.
• E. A pluggable database within a multi-tenant standby database can have a different database role than the container database.

Correct answer: A, D

Explanation

Option A is correct because each pluggable database needs a unique DB_UNIQUE_NAME in a multi-tenant standby setup to avoid conflicts. Option D is also correct as a pluggable database can indeed operate in a different open mode than the container database. Options B, C, and E are incorrect because they do not accurately reflect the requirements or behaviors of pluggable databases in Data Guard environments.
