Nutanix NCP-DB Exam - Topic 3 Question 35 Discussion

Actual exam question for Nutanix's NCP-DB exam

Question #: 35
Topic #: 3

A DBA executed a script which corrupted an Oracle DB managed by NDB. After few minutes, the NDB administrator has been asked to create a copy of the DB using the latest available snapshot.

Which actions should be taken?

AFail the Oracle cluster over to a surviving RAC node.

BSelect the snapshot from Time Machine and create a new clone.

CUse Time Machine to create a clone from file-level database backup.

DProvision a new Oracle DB and perform log catch-up.

Show Suggested Answer

Suggested Answer: B

After a DBA's script corrupts an Oracle DB managed by NDB, the administrator needs to restore a clean copy using the latest available snapshot. The most straightforward action is to use the NDB Time Machine feature to select the most recent uncorrupted snapshot and create a new clone. This clone can serve as a restored version of the database, bypassing the corrupted data while leveraging existing snapshots for efficiency.

Option A (Fail the Oracle cluster over to a surviving RAC node) is incorrect because RAC failover is for HA, not corruption recovery via snapshots.

Option B is correct as it uses Time Machine to create a clone from a valid snapshot, addressing the corruption.

Option C (Use Time Machine to create a clone from file-level database backup) is incorrect because NDB primarily uses snapshots, not file-level backups, for cloning.

Option D (Provision a new Oracle DB and perform log catch-up) is incorrect because provisioning a new DB is more complex and unnecessary when a snapshot-based clone suffices.

This method ensures rapid recovery with minimal disruption.

A is definitely not the right choice here.

Wait, can you really use Time Machine for this?

I’m a bit confused about the log catch-up option; I thought that was more for restoring from a backup rather than creating a new DB.

I practiced a similar question where we had to choose between snapshots and backups, and I feel like creating a clone from a file-level backup might be the safest bet.

I think failing over to a surviving RAC node could be a good option, but I need to double-check if that would actually help in this case.

I remember we discussed the importance of using snapshots for recovery, but I'm not sure if Time Machine is the right tool for this situation.

This seems straightforward. The DBA corrupted the database, so we need to create a new copy from the latest snapshot. Option B is the clear choice here.

I'm not too familiar with NDB, so I'll need to make sure I understand how that fits into the scenario. But I think I can narrow it down to a couple of options.

Okay, I think I've got this. The key is to create a copy of the database using the latest available snapshot. Option B looks like the way to go.

Hmm, I'm a bit confused by the mention of Time Machine. That's not an Oracle feature, is it? I'll have to double-check that.

I think we should use Time Machine to create a clone from file-level database backup instead.

Hmm, let's see... Failing over to a RAC node doesn't sound like the right move here. I'm leaning towards option C - using Time Machine for a file-level backup. Sounds like the safest bet to me.

Whoa, this is a tricky one! Gotta love those Oracle database disasters, am I right? I'm going with option D - time to provision a new DB and catch up on those logs. Yee-haw!
