Q

LRS

A

Single region

Three replicas, one region

Protect against disk, node, rack failures

Write is acknowledged when ALL replicas are committed

Superior to dual-parity RAID

Q

What is Storage’s URL based on

A

Account name and storage type

blobs.contoso.com has name contosoblobs.blob.core.windows.net

20
Q

How to secure storage accounts

A

Firewalls and Virtual networks restrict access to the Storage Account from specific subnets on Virtual Networks or public IPs

Subnets and Virtual Networks must exist in the same Azure Region or Region Pair as the Storage Account

21
Q

Binary Large Object (Blob) Storage

A

Stores unstructured data in the cloud

Store text or binary data

AKA object storage

22
Q

BLOB common usage

A

Serve images or documents directly to browser

Store files for distributed access

Stream video and audio

fill

23
Q

Blob Container

A

Store BLOB in this

Accounts have unlimited containers

Containers have unlimited blobs

24
Q

Three type of BLOB containers

A

Private blobs

Blob access

Container access

25
Q

Private blobs

A

No anonymous access

26

32
Q

Blob Lifecycle Management

A

Transition blobs to cooler storage tier to optimize for performance and cost

Delete blobs at the end of their lifecycle

Apply rules to filtered paths in the Storage Account

33
Q

Blob Object Replication

A

Asynchronous to any other Region

Minimizes latency for read requests

Increases efficiency for compute workloads

Optimizes data distribution

Optimizes costs

34
Q

Uploading Blobs - what to specify

A

Authentication type - Azure AD account or Account key

Block blobs

Page blobs

Append blobs

Cannot change blob type once it has been created

35
Q

What are Shared Access Signatures

A

Provide delegated access to resources

Grants access to clients w/o sharing your storage a/c keys

Account SAS delegates access to resources in one or more of the storage services

Service SAS delegates access to a resource in just one of the storage services

36
Q

What is Storage Service Encryption

A

Protects your data for security and compliance

Automatically encrypts and decrypts your data

Encrypted through 2556-bit AES encryption

Is enabled for all new and existing storage accounts and cannot be disabled

Is transparent to users

37
Q

Customer Managed Keys

A

Use Azure Key Vault to manage your encrypted keys

Create your own encryption keys and store them in a key vault

Use Azure Key Vault’s APIs to generate encryption keys

Custom keys give you more flexibility and control

38
Q

Azure Files Description

A

SMB interface, client libraries, and a REST interface that allows access from

39
Q

Managing File Shares

Linux - mount the drive

MacOS - mount the drive

40
Q

File Share Snapshots

A

Incremental snapshot that captures the share state at a point in time

41
Q

Azure File Sync

A

Centralize your organization’s file shares in Azure files, while keeping the flexibility, performance, and compatibility of an on-prem file server

42
Q

File Sync Components

A

Storage Sync Service

Registered server

What is Storage Explorer

A

Access multiple accounts and subscriptions

Create, delete, view, edit storage resources

View and edit Blob, Queue, Table, File, Cosmos DB storage and Data Lake Storage

Obtain shared access signature (SAS) keys

Available for Windows, Mac, and Linux

45
Q

Import and Export Service

A

Import Jobs - move large amounts of data to Azure blob storage or files

Export Jobs - move large amounts of data from Azure Storage (not files)
