Question 1

Which Azure service enables bidirectional file sync between on-premises Windows Server file shares and Azure Files?

Accepted Answer

Azure File Sync

Answer

Azure File Sync keeps on-premises Windows Server shares in sync with Azure Files, enabling cloud tiering to free up local storage.

Question 2

What is 'cloud tiering' in the context of Azure File Sync?

Accepted Answer

Automatically moving less-accessed files to Azure while keeping a local pointer (stub)

Answer

Cloud tiering offloads infrequently accessed files from local disk to Azure Files, replacing them with stubs to free up on-premises storage while maintaining namespace.

Question 3

Which Azure Storage feature enables storing multiple versions of a blob, protecting against accidental overwrites?

Accepted Answer

Blob Versioning

Answer

Blob Versioning automatically preserves previous versions of a blob whenever it is overwritten, allowing restoration to any earlier version.

Question 4

What is the purpose of Azure Storage 'Object Replication' for blobs?

Accepted Answer

Asynchronously replicates blobs between source and destination storage accounts for compliance or latency reduction

Answer

Object Replication asynchronously copies block blobs between storage accounts, useful for data distribution, latency optimization, or backup.

Question 5

Which Azure Storage performance tier provides sub-millisecond latency for high-transaction workloads using SSD-backed storage?

Accepted Answer

Premium performance tier

Answer

The Premium performance tier uses SSD-based storage to deliver consistent sub-millisecond latency, ideal for high-IOPS applications like databases.
