Answer options

• A. A configuration consisting only of a primary and one or more physical standby databases can support a rolling release upgrade.
• B. A Logical Standby Database can be converted to a Snapshot Standby Database.

• D. A Snapshot Standby Database can be a fast-start failover target.
• E. A Physical Standby Database can be converted into a Logical Standby Database.

Correct answer: B, E

Explanation

Option B is correct because a Logical Standby Database can indeed be converted to a Snapshot Standby Database, allowing for flexibility in database roles. Option E is also correct as it is possible to convert a Physical Standby Database into a Logical Standby Database. The other options either misrepresent the capabilities of the databases or are not true in the context of Oracle Data Guard.
