You have a volume storing a large number of 1KB to 2KB compressed zip files.
In this scenario, which storage efficiency feature should you use?

In a scenario with a large number of 1KB to 2KB compressed zip files, the most suitable storage efficiency feature to use would be data compaction. This is because data compaction can reduce the amount of wasted space by packing multiple small data chunks into a single 4KB physical block, thus optimizing the storage efficiency for such small files. Since the files are already compressed, applying additional compression techniques like secondary or adaptive compression wouldn't be effective. Deduplication is also not useful here as it relies on the presence of duplicate data, which is unlikely with unique zip files.
Definitely data compaction. It's a give away when it mentions multiple 1KB and 2KB files and then you think about the 4KB block size and how much is wasted. "While the data is still in the controller memory, we take data chunks that would each normally consume an entire 4KB block on physical storage and we compact the chunks. With compaction, more than one chunk fits into a single 4KB physical block." https://community.netapp.com/t5/Tech-OnTap-Articles/A-Look-Inside-NetApp-Inline-Data-Compaction/ta-p/122362 https://www.netapp.co.uk/company/newsletters/tot-a-look-inside-netapp-inline-data-compaction-1608.aspx
data compaction
ans is A
Compression makes no sense as it's already compressed by ZIP. Dedup also no sense cause no blocks are duplicate. Therefore A is the only logical answer and runnerbean has stated the feature very clearly.
