Which three statements are true about snapshot standby databases?

Show Suggested Answer Hide Answer
Suggested Answer: B, C, E

A snapshot standby database is a fully updateable standby database that is created by converting a physical standby database into a snapshot standby database. The main characteristics of a snapshot standby database include:

B: Tablespaces can indeed be dropped in a snapshot standby database because it is updateable and allows all types of DML and DDL operations that do not conflict with the standby role.

C: Tablespaces can be created in a snapshot standby database for the same reasons that they can be dropped; it supports all operations that do not interfere with its standby nature.

E: Tables can be dropped in a snapshot standby database, as it is a fully updateable standby.

Options A and D are incorrect because 'FAILOVER TO' and 'SWITCHOVER TO' commands are not used with snapshot standby databases in these contexts. A failover converts a standby database into the primary role after the original primary has become unavailable, and is not a reversible role transition. Switchover is a planned role reversal between the primary database and one of its standby databases and is not applicable to snapshot standby databases in the context provided.

Option F is incorrect because a logical standby database cannot be converted into a snapshot standby database directly. A logical standby is used for different purposes such as reporting and querying with real-time data, and its structure is different from a physical standby which can be converted into a snapshot standby.

B is tricky. I think it depends on whether FLASHBACK DATABASE was already enabled on the physical standby before the conversion.

Haha, read-write on a snapshot standby? That's like driving with the emergency brake on!

Totally, it's meant for reporting purposes only.

Yeah, opening a snapshot standby read-write defeats the purpose.

I believe statement D is true because Real-Time apply can be enabled on a snapshot standby database. So, I think A and D are true statements about snapshot standby databases.

I'm not sure about statement D, but I think it's possible. Let's wait for more opinions from other candidates.

I agree with A and D, but I'm not sure about C. Doesn't FLASHBACK DATABASE have to be enabled manually on the physical standby first?

That makes sense. So, A, C, and D are all true statements about snapshot standby databases.

So, statement C is true. It's automatically enabled during the conversion process.

Actually, FLASHBACK DATABASE is enabled automatically on a physical standby when converting to a snapshot standby if not already enabled.

I think you're right, FLASHBACK DATABASE needs to be enabled manually on the physical standby before converting to a snapshot standby.

I agree with Glynda. Statement A makes sense to me. But what about statement D? Can a snapshot standby database have Real-Time apply enabled?

I think statement A is true because I remember reading about snapshot standby databases being able to be opened read-only.
