NetApp Exam NS0-521 Topic 3 Question 19 Discussion

Actual exam question for NetApp's NS0-521 exam

Question #: 19
Topic #: 3

A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.

What could cause this behavior?

ASnapshot autodelete

BAggregate overcommitted

CVolume thinly provisioned

DAutonomous Ransomware Protection

Show Suggested Answer

Suggested Answer: A

To move a WWPN from node1 to node2 in a NetApp ONTAP SAN environment where ALUA is used, you must take the Logical Interface (LIF) offline. Modifying LIFs involves changing their assignment between nodes, which requires them to be temporarily offline. This ensures that the path states are correctly updated without causing disruption to the SAN hosts.

Hold up, did someone say 'ransomware'? That's like a horror movie, but with more data loss and less popcorn. I bet the snapshots just ran away in fear. Maybe they're hiding under the desk, waiting for the all-clear.

Ooh, tricky one. I'm going with D, Autonomous Ransomware Protection. Sounds like something straight out of a sci-fi movie, where the storage system decides to protect itself by deleting the evidence. Now that's some next-level self-preservation.

Alright, let's think this through. C, Volume thinly provisioned. Gotta love when the storage is as thin as a supermodel's waistline. Probably couldn't handle the ransomware's appetite for encryption.

B: Definitely, it's all about balancing capacity and performance. Thin provisioning can be risky if not managed properly.

A: Yeah, that thin provisioning can really come back to bite you. It's like trying to fit a square peg in a round hole.

Hmm, let's see... B, Aggregate overcommitted. Maybe the storage system was so full, it had to sacrifice the snapshots to the data gods. Either that, or the ransomware was doing some serious space-age data compression.

A, Snapshot autodelete. The system might have automatically deleted the snapshots to free up space.

C, Volume thinly provisioned. Maybe the ransomware took advantage of the thin provisioning.

Whoa, no snapshots? That's like a bad magic trick, but with ransomware instead of rabbits. I'd go with A, Snapshot autodelete. Gotta love when the system deletes the evidence faster than a politician deletes their emails.
