How should you manage the data?

HOTSPOT

You have an Azure Data Lake Storage Gen2 container.

Data is ingested into the container, and then transformed by a data integration application. The data is NOT modified after that. Users can read files in the container but cannot modify the files.

You need to design a data archiving solution that meets the following requirements:

✑ New data is accessed frequently and must be available as quickly as possible.

✑ Data that is older than five years is accessed infrequently but must be available

within one second when requested.

✑ Data that us older than seven years is NOT accessed. After seven years, the data must be persisted at the lowest cost possible.

✑ Costs must be minimized while maintaining the required availability.

How should you manage the data? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Box 1: Move to cool storage

The cool access tier has lower storage costs and higher access costs compared to hot storage. This tier is intended for data that will remain in the cool tier for at least 30 days.

Example usage scenarios for the cool access tier include:

Short-term backup and disaster recovery

Older data not used frequently but expected to be available immediately when accessed Large data sets that need to be stored cost effectively, while more data is being gathered for future processing

Note: Hot – Optimized for storing data that is accessed frequently. Cool – Optimized for storing data that is infrequently accessed and stored for at least 30 days.

Archive – Optimized for storing data that is rarely accessed and stored for at least 180 days with flexible latency requirements, on the order of hours.

Box 2: Move to archive storage

Example usage scenarios for the archive access tier include:

Long-term backup, secondary backup, and archival datasets

Original (raw) data that must be preserved, even after it has been processed into final usable form

Compliance and archival data that needs to be stored for a long time and is hardly ever accessed
