You have an Azure Storage account that contains two 1-GB data files named File1 and File2. The data files are set to use the archive access tier.
You need to ensure that File1 is accessible immediately when a retrieval request is initiated.
Solution: For File1, you set Access tier to Cool.
Does this meet the goal?

A. Yes
B. No

Show Suggested Answer

Suggested Answer: B 🗳️
Instead use the hot access tier.
The hot access tier has higher storage costs than cool and archive tiers, but the lowest access costs. Example usage scenarios for the hot access tier include:
✑ Data that's in active use or expected to be accessed (read from and written to) frequently.
✑ Data that's staged for processing and eventual migration to the cool access tier.

I think it is "Yes", since both with cool and hot tier the data will be available immediately. It just costs less with hot access tier to access the data frequently.

Answer should be YES. Cool Tier provides the same read response time as Hot.

Hot provides single-digit ms "time to first byte", cool provides several ms. Not exactly same, else hot wouldn't make any sense. :)

Option B is correct as immediate access in Cool tier will be available only for short duration (30 days)

It is not correct what you say. The data in the cool tier is "considered / intended to be stored for 30 days". But this is not a must. You can store data indefinitely in the cool tier. The mentioned reference (see below) even gives an example of large scientific or otherwise large data which is stored for long duration in the cool tier. https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers?tabs=azure-portal In cool you enjoy less costs for long term storage than in hot. This is especially good in case you have a lot of GB/TB (in our case we have large files) but you still need an immediate access. So cool makes actually very good sense.

I think the answer should be Yes. There is no requirement for how frequently files will be accessed nor there is any cost requirement. Strictly looking at the only requirement of "ensure that File1 is accessible immediately when a retrieval request is initiated", COOL Tier satisfies it.
