Implement and manage storage Flashcards
What are the 3 categories of Azure Data
Virtual Machine data, unstructured data, structured data
give a brief description and example of virtual machine data
Storage includes disks and files. Provided through azure managed disks used by VM’s
Give a brief description and example of unstructured data
Non relational data, generally used within blob storage and data lake storage
Give a brief description and example Structured Data
Data stored in a relational format with a shared schema- Azure tables, azure cosmos db, azure SQL
General Purpose Storage accounts: two tiers avaliable?
Standard (Magnetic HDD)
Premium (SSD)
What four data services can be accessed by using an azure storage acccount
Blob storage (containers)
Azure files: file sharing
Queue Storage: messaging store for reliable messaging between application components
Table Storage: Non relational structure Data
What is blob storage IDEAL for?
Serving images or documents directly to a browser
streaming video and audio
storing files for distributed access
Storing data for backup and restore, disaster recovery, and archiving.
What is Azure Files Ideal for
Files sharing
What is azure queue storage ideal for
Example given- creating a thumbnail while uploading a picture- 64kb is the max size so it’s used for very small processes
What is azure table storage used for
Azure Cosmos DB- Non relational Data
What are the 4 available storage account options
Standard general- purpose v2
Premium Block Blobs
Premium File Shares
Premium Page blobs
Which storage account option has the following supported services: Blob storage, queue storage, table storage, and azure files
Standard general- purpose v2
Which storage account option has the following supported services: Blob Storage and data lake
Premium block blobs
Which storage account option has the following supported services: Azure Files
Premium File Shares
Which storage account option has the following supported services: Page blobs only (NO DATA LAKE)
Premium Blobs only
Recommended Usage: Standard General v2
Most scenarios are ideal
Recommended Usage: Premium Block Blobs
High transaction rates. Used with small objects or require low storage latency.
Recommended usage: Premium File Shares
Enterprise file shares that require support for both smb and nfs file shares
Recommended Usage: Premium page blobs
Ideal for storing index-based and spare data structures, such as OS, data disks for virtual machines, and databases
What are the 4 replication strategies?
Locally redundant storage (LRS)
Zone redundant storage (ZRS)
Geo-redundant storage (GRS)
Geo-zone-redundant storage (GZRS)
what benefits are there for choosing LRS
Used for easily Reconstructed Data, consistently changing data, or perhaps if your data is restricted due to government requirements
What the benefits and drawbacks of ZRS
Not avaliable in all regions. Allows for greater redundancy as it replicates data across 3 storage clusters in a single region
What are the benefits of GRS
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
What are the benefits of RZRS
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
Storage account URL address
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
can a container store an unlimited number of blobs?
yes
list and describe the 3 types of blobs
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)
Please list the blob access tiers
hot tier
cool tier
archive tier
can you change the type of blob once it’s created?
no
Data can be secured in transit between an application and Azure by using what?
client-side encryption, https, smb 3.0
what is azure storage explorer?
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
What service allows companies to ship disk drives to and from azure data centers for import/export purposes
Import/export services
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.
WAImportalexport tool
Do disk for azure import jobs need to be encrypted?
yes, with bitlocker for each ntfs volume
Which command line utility is used for copying data to and from azure blob and azure files
AzCopy
Do names for storage accounts need to be globally unique?
yes
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?
If you have an issue with azure file sync, should you unregister the server to troublehoot?
no
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 dataset csv and a driveset csv
What is the minimum amount of copies LRS replication holds?
3
