To limit the amount of resources a client can use to prevent service abuse.

38
Q

How does Azure Storage secure data in transit?

A

Using HTTPS to encrypt data during transmission.

39
Q

A

To create a point-in-time copy of a blob for backup or archival.

40
Q

What is Azure Storage Redundancy?

A

The replication of data to ensure high availability and durability.

41
Q

What is the purpose of ZRS in Azure Storage?

A

To provide redundancy by replicating data across availability zones.

42
Q

What is the maximum retention period for Azure Blob Soft Delete?

A

365 days.

43
Q

What is Azure Archive Storage best suited for?

A

Data that is rarely accessed but needs to be stored for a long time.

44
Q

What is Azure File Sync?

A

A service that syncs file shares across Windows servers and Azure File Storage.

45
Q

How do you monitor an Azure Storage Account?

A

Using Azure Monitor, Storage Analytics, or Azure Metrics.

46
Q

What is Azure Storage Firewall?

A

A security feature that restricts access to storage accounts by IP addresses.

47
Q

What is the maximum size of an individual Azure File Share?

A

Up to 100 TiB.

48
Q

What is Cross-Origin Resource Sharing (CORS) in Azure Storage?

A

A feature that allows scripts on web pages to access data in a storage account from a different domain.

49
Q

What is Azure File Sync?

A

It is a software that, when installed locally on a server, enables the caching and servicing of files locally thet can be accessed using SMB and NFS.

50
Q

What is Azure File Sync cloud tiering?

A

Azure File Sync cloud tiering enables

51
Q

When using Azure File Sync, can you have multiple sites?

A

Azure File Sync is ideal for distributed access scenarios. For each office, you can provision a local Windows Server as part of your Azure File Sync deployment. Changes made to a server in one office automatically sync to the servers in all other offices.

52
Q

What redundancy options does Azure File Sync rely on?

A

Azure File Sync is backed by Azure Files, which offers several redundancy options for highly available storage.

53
Q

What happens to your local server in an Azure File Sync deployment if it fails?

A

The local server becomes a disposable caching device, and recovery involves provisioning another Windows Server.

54
Q

What is the first step to recover from a failed server in Azure File Sync without a local backup?

A

Provision another Windows Server, install the Azure File Sync agent and add it to the Azure File Sync deployment.

55
Q

How does Azure File Sync optimize recovery speed after adding a new server?

A

Azure File Sync downloads your file namespace before downloading data, allowing the server to be operational quickly.

56
Q

What can you use for faster disaster recovery in Azure File Sync?

A

You can have a warm standby server or use Azure File Sync with Windows Clustering for faster recovery.

57
Q

What is the key benefit of using Azure File Sync for business continuity?

A

Azure File Sync ensures resilience by storing copies of your data in Azure, making the local serverless critical for recovery.

58
Q

Can you backup Azure Storage Account Files with Azure Backup

A

Yes

59
Q

What protocols does Azure File Sync Support?

A

SMB and NFS

60
Q

When using Azure File Sync, what is a sync group?

A

In Azure File Sync, a sync group is a fundamental concept that defines how and where files are synchronized. A sync group contains a cloud endpoint and one or more server endpoints, which determine the locations for syncing files. Here’s how it works:

  • Cloud Endpoint: This is the Azure file share in an Azure Storage Account that acts as the central repository for your synchronization.
  • Server Endpoint: This is the path on a registered server (typically an on-premises server or a virtual machine) that you want to sync with the cloud endpoint.
61
Q

What is an access tier for Azure Storage?

A

An access tier in Azure Storage determines the cost and performance balance for data based on its access frequency. It optimizes storage costs by categorizing data as Hot (frequently accessed), Cool (infrequently accessed), or Archive (rarely accessed, long-term storage). Each tier has different pricing for storage and retrieval to suit varying data access needs.

62
Q

Can you convert a LRS Azure storage Account to GRS?

A

Yes this is supported.

63
Q

Can you convert a ZRS Azure storage Account to GRS?

A

Yes this is supported.
