(2) Describe Azure storage services

Question 1

What are the storgae options for Azure?

Answer 1

1. General Purpose V2; 2. Block Blobs; 3. File Shares: 4. Page Blobs

Question 2

These must be between 3 and 24 characters in length and may contain nubmer and lowercase letters only; it must also be unique within Azure. No two storage accounts can have the same one. This supports the ability to have a unique, accessible namespace in Azure.

Answer 2

Storage Account Naming

Question 3

Always stores multiple copies of your data so that it’s protected from planned and unplanned events such a transient hardware failures, network or power outages, and natural disasters.

Answer 3

Storage Redundancy

Question 4

This replicates your data 3 times within a single datacenter in the primary region. It provides at least 11 nines of durability of objects over a given year.

Answer 4

Locally Redundant Storage (LRS)

Question 5

This replicates your data synchronously accross 3 availability zones in the primary region. It provides at least 12 nines of durability of objects over a given year. Your data is still accessible for both read and write operations.

Answer 5

Zone-Redundant Storage (ZRS)

Question 6

Microsoft recommends using this type of storage option in the primary region for scenarios that require high availability. it is also recommended for restricting replication of data within a country or region to meet data governance requirements.

Answer 6

Zone-Redundant Storage (ZRS)

Question 7

Copies your data synchronously 3 times within a single physical location in the primary region using LRS. It then copies your data asynchronously to a signle physical location in the secondary region (the region pair) using LRS. It provides at least 16 nines of durability of objects over a given year. Data is read only if the customer or Microsoft initiates a failover.

Answer 7

Geo-Redundant Storage (GRS)

Question 8

Data is is copied across 3 Azure availability zones in the primary region (similar to ZRS) and is also replicated to a secondary geographic reason, using LRS, for protection from regional disasters.

Answer 8

Geo-Zone-Redundant Storage (GZRS)

Question 9

If you enable read access to secondary region, your data is always available, even when the primary region is running optimally.?????

Answer 9

Read-Access Geo-Redundant Storage (RA-GRS)

Question 10

If you enable read access to secondary region, your data is always available, even when the primary region is running optimally.

Answer 10

Read-Access Geo-Zone-Redundant Storage (RA-GZRS)

Question 11

A massively scalable object store for text and binary data. Also includes support for big data analytics through Data Lake Storage GEN2. It is unstructured, meaning that there are no restrictions on the kinds of data it can hold.

Answer 11

Azure Blobs

Question 12

Use Cases: This storage type is useful for the following scenarios: Serving images or documents directly to a browser; storing files for distributed access; streaming videos and audio; storing data for back-up and restore, disaster recovery, and archiving. Access tiers can be set at this level, during or after uploads.

Answer 12

Blob Storage

Question 13

Optimized for storing data that is accessed frequently (for example, images for your website); this access tier can be set at the account level

Answer 13

Hot Access Tier

Question 14

Optimized for data that is infrequently accessed and stored for at least 30 days (for exmpale, invocies for your customers); this access tier can be set at the account level

Answer 14

Cool Access Tier

Question 15

Appropriate for data that is rarely accessed and stored for at least 180 days, with flexible latency requirements (for example, long-term back-ups); stores data offline and offers the lowest storage costs, but also the highest costs to rehydrate and access the data.

Answer 15

Archive Access Tier
