Q

Recommended Usage: Premium Block Blobs

A

High transaction rates. Used with small objects or require low storage latency.

18
Q

Recommended usage: Premium File Shares

A

Enterprise file shares that require support for both smb and nfs file shares

19
Q

Recommended Usage: Premium page blobs

A

Ideal for storing index-based and spare data structures, such as OS, data disks for virtual machines, and databases

20
Q

What are the 4 replication strategies?

A

Locally redundant storage (LRS)
Zone redundant storage (ZRS)
Geo-redundant storage (GRS)
Geo-zone-redundant storage (GZRS)

21
Q

what benefits are there for choosing LRS

A

Used for easily Reconstructed Data, consistently changing data, or perhaps if your data is restricted due to government requirements

22
Q

What the benefits and drawbacks of ZRS

A

Not avaliable in all regions. Allows for greater redundancy as it replicates data across 3 storage clusters in a single region

23
Q

What are the benefits of GRS

A

16 9’s or reliability (99.99999999999999%), replicates data to secondary region. Important Read acess GRS allows you to read from the secondary region regardless of whether Microsoft has initialized a fail over to the secondary region

24
Q

What are the benefits of RZRS

A

combines the high availability of zone-redundant storage with protection from regional outages as provided by geo-redundant storage. Data in a GZRS storage account is replicated across three Azure availability zones in the primary region, and also replicated to a secondary geographic region for protection from regional disasters. Each Azure region is paired with another region within the same geography, together making a regional pair

25
Q

Storage account URL address

A

Container Service //mystorageaccount.blob.core.windows.net
Table Service
//mystorageaccount.table.core.windows.net
Queue Service
//mystorageaccount.queue.core.windows.net
File Service
//mystorageaccount.file.core.windows.net

26
Q

can a container store an unlimited number of blobs?

A

yes

27
Q

list and describe the 3 types of blobs

A

Block blob: ideal for storing text and binary data items like files, images, and videos
Page Blob: Used in Azure Virtual Machines for operating systems disks and data disks
Append blob: useful for logging (8 tb size limit)

27
Q

Please list the blob access tiers

A

hot tier
cool tier
archive tier

28
Q

can you change the type of blob once it’s created?

A

no

29
Q

Data can be secured in transit between an application and Azure by using what?

A

client-side encryption, https, smb 3.0

30
Q

what is azure storage explorer?

A

A standalone application that makes it easy to work with azure storage data on windows, macos, and linux. you can access multiple accounts and subscriptions and manage all of your storage content

31
Q

What service allows companies to ship disk drives to and from azure data centers for import/export purposes

A

Import/export services

32
Q

WAImportExport is the Azure Import/Export service tool. The tool is used to prepare drives before importing data, and to repair any corrupted or missing files after data transfer.

A

WAImportalexport tool

33
Q

Do disk for azure import jobs need to be encrypted?

A

yes, with bitlocker for each ntfs volume

34
Q

Which command line utility is used for copying data to and from azure blob and azure files

A

AzCopy

35
Q

Do names for storage accounts need to be globally unique?

A

yes

36
Q

Practice Question: You need to synchronize the files in the file share with an on-premise server named Getcloudskillsserver. what are the 3 steps you need to implement to fulfill this requirement?

A
37
Q

If you have an issue with azure file sync, should you unregister the server to troublehoot?

A

no

38
Q

You plan to use the Azure Import/Export service to copy files to a storage account. Which two files should you create before you prepare the drives for the import job?

A

a dataset csv and a driveset csv

39
Q

What is the minimum amount of copies LRS replication holds?

A

3
