If you have two nines of durability (99%), how much time might that data not be accessible per year?
36.53 days
3.65 days
52.6 minutes
Answer explanation
Two nines of durability (99%) translates to 1% downtime.
Assuming a year has 365 days (ignoring leap years for simplicity), this would mean the data might be inaccessible for approximately:
Downtime percentage: 1%
Days in a year: 365 days
Downtime hours = Downtime percentage Days in a year Downtime hours = 1/100 365 days Downtime hours ≈ 3.65 days per year

You are a healthcare provider looking to store a large archive of medical images from patients. These images are rarely accessed, but need to be readily available for retrieval upon patient request, which could happen years later. However, due to budget constraints, you want to choose the most cost-effective storage option. What Azure Storage access tier would be the most suitable for this scenario?
Hot
Cool
Cold
Archive
Answer explanation
Hot Access tier is designed for frequently accessed data and would be too expensive for infrequently accessed medical images.
Cool Access tier is a good option for data that might be needed occasionally within a few months, but for medical images that could be needed years later, it might not be the most cost-effective.
Cold Access tier is a viable option as it offers lower storage costs compared to Cool tier. Data retrieval times from Cold storage are typically longer (hours) compared to Cool tier, but acceptable for this scenario where urgency is not a major concern.
Archive Access tier is the most cost-effective option for data that is rarely accessed and retrieval times of several hours are acceptable. Medical images in this scenario fit this profile perfectly. Retrieving data from Archive tier takes longer (hours) compared to Cold tier, but the significant cost savings make it the most suitable choice.
While both Cold and Archive tiers could be considered, Archive tier offers the lowest storage costs, making it the most cost-effective option for this specific scenario.
