Microsoft Certifications DP-201 Online Exam Practice Questions
QUESTION 1
You need to design the disaster recovery solution for customer sales data analytics.
Which three actions should you recommend? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Provision multiple Azure Databricks workspaces in separate Azure regions.
B. Migrate users, notebooks, and cluster configurations from one workspace to another in the same region.
C. Use zone redundant storage.
D. Migrate users, notebooks, and cluster configurations from one region to another.
E. Use Geo-redundant storage.
F. Provision a second Azure Databricks workspace in the same region.
Correct Answer: ADE
Scenario: The analytics solution for customer sales data must be available during a regional outage.
To create your own regional disaster recovery topology for databricks, follow these requirements:
Provision multiple Azure Databricks workspaces in separate Azure regions
Use Geo-redundant storage.
Once the secondary region is created, you must migrate the users, user folders, notebooks, cluster configuration, jobs
configuration, libraries, storage, init scripts, and reconfigure access control.
Note: Geo-redundant storage (GRS) is designed to provide at least 99.99999999999999% (16 9\\’s) durability of objects
over a given year by replicating your data to a secondary region that is hundreds of miles away from the primary region.
If
your storage account has GRS enabled, then your data is durable even in the case of a complete regional outage or a
disaster in which the primary region isn\\’t recoverable.
