Learn how to configure secure access and implement storage replication strategies in Azure, optimizing cost and performance for diverse data requirements within your organization.
Your organization has diverse requirements for their cloud-hosted data. You’re responsible for designing a plan to configure secure access.
- The admin team requests your help with implementing a storage replication strategy. They have questions about how to configure storage accounts.
- The manufacturing division has sensors that record time-relative data. Only the most recent data is useful. The company wants the lowest cost storage solution for this data.
Question 1
Which storage solution replicates data to a secondary region, and maintains six copies of the data?
A. Locally redundant storage
B. Read-access geo-redundant storage
C. Zone-redundant storage
Answer
B. Read-access geo-redundant storage
Explanation
Read-access geo-redundant storage is the default replication option. Geo-redundant storage (GRS) copies the data synchronously three times within a single physical location in the primary region by using LRS. The data is then copied asynchronously to a single physical location in the secondary region.
A is incorrect. Locally redundant storage replicates data three times within a single data center in the primary region.
C is incorrect. Zone-redundant storage replicates Azure Storage data synchronously across three Azure availability zones in the primary region.
Question 2
The admin team needs to know the requirements for storage account names. To what extent does a storage account name need to be unique?
A. The name must be unique within the containing resource group.
B. The name must be unique within the organization’s subscription.
C. The name must be globally unique.
Answer
C. The name must be globally unique.
Explanation
The storage account name is used as part of the URI for API access, so it must be globally unique.
A is incorrect. A storage account name doesn’t have to be unique in a resource group.
B is incorrect. A storage account name doesn’t have to be unique in an Azure subscription.
Question 3
What’s the best storage account solution to support the requirements of the manufacturing division?
A. Locally redundant storage
B. Geo-redundant storage
C. Zone-redundant storage
Answer
A. Locally redundant storage
Explanation
Locally redundant storage is the best choice. It’s the lowest cost solution, the data is being continuously created, and data loss isn’t an issue.
B and C are incorrect. Is there a lower-cost solution for temporary data?
