2. Design data storage solutions

Question 1

What are the key considerations when designing a storage solution in Azure?

Answer 1

Key considerations include

data durability

availability

performance

scalability

security

cost optimization.

Question 2

How can you ensure high availability for your Azure Storage account?

Answer 2

ou can ensure high availability by enabling geo-redundant storage, which replicates your data to a secondary region.

Question 3

What are the differences between Azure Blob storage and Azure Files?

Answer 3

Azure Blob storage is designed for storing unstructured data, while Azure Files provides fully managed file shares that can be accessed via the Server Message Block (SMB) protocol.

Question 4

How can you secure data in Azure Storage?

Answer 4

Data in Azure Storage can be secured by using access control mechanisms like Shared Access Signatures (SAS), Azure AD authentication, and role-based access control (RBAC).

Question 5

What is the purpose of Azure Data Lake Storage?

Answer 5

Azure Data Lake Storage is designed for big data analytics workloads, providing a scalable and secure repository for storing large amounts of structured and unstructured data.

Question 6

How can you optimize costs when using Azure Storage?

Answer 6

Cost optimization can be achieved by choosing the appropriate storage tier (e.g., hot, cool, or archive), using lifecycle management to move data to lower-cost tiers, and leveraging features like data deduplication and compression.

Question 7

What is Azure Table storage used for?

Answer 7

Azure Table storage is a NoSQL key-value store that is suitable for storing large amounts of structured, non-relational data, such as sensor data or customer profiles.

Question 8

How can you transfer large amounts of data to Azure Storage?

Answer 8

Large data transfers can be accomplished using Azure Data Box, Azure Import/Export service, or by leveraging Azure Data Factory for data integration and movement.

Question 9

What is the purpose of Azure Backup?

Answer 9

Azure Backup is a cloud-based service that provides backup and restore capabilities for Azure virtual machines, on-premises systems, and Azure Files shares.

Question 10

How can you monitor and analyze Azure Storage performance?

Answer 10

Azure provides various monitoring and analytics tools, such as

Azure Monitor

Azure Storage Analytics

Azure Log Analytics

…to monitor and analyze storage performance, track metrics, and detect anomalies.

Question 15

How can you efficiently transfer large amounts of data to Azure Blob storage?

Answer 15

By using Azure Data Box or Azure Data Box Disk

Question 16

What is the purpose of Soft Delete in Azure storage?

Answer 16

Soft Delete helps in recovering data that is accidentally deleted or overwritten within the retention period

Question 17

Which Azure service provides a fully managed, columnar data store for petabyte-scale analytics?

Answer 17

Azure Synapse Analytics (formerly SQL Data Warehouse)

Question 18

How can you monitor and analyze Azure Storage performance?

Answer 18

By using Azure Monitor and Azure Storage Analytics

Question 19

What are update domains in Azure availability sets?

Answer 19

Update domains are logical groups of virtual machines that are updated and restarted together during planned maintenance events

Question 20

How can you set up scalability parameters for Azure SQL Managed Instances?
