Implement and manage storage

Question 1

What storage type would you store a VM Image on?

Answer 1

Blob Storage

Question 2

What is the protocol port used for SMB?

Answer 2

Port 445

Question 3

What dose SMB stand for?

Answer 3

Server Message Block

Question 4

What is SMB?

Answer 4

The Server Message Block (SMB) protocol is a client-server communication protocol that is used for shared access to files on a network.

Question 5

What is a blob data protection?

Answer 5

Data protection is another way to manage data in Azure Blobs. Using things like
- blob versioning
- blob soft deletes
- backups
- restore points

Question 6

What is Access Keys?

Answer 6

A secure way to give someone access to your storage account instead of using an account

Question 6

What are three points to remember about Access Keys?

Answer 6

Access keys are mainly used in Azure Storage Explorer.
You get two access keys per storage account
It will limits access to just one storage account

Question 6

What dose SAS stand for?

Answer 6

Shared access signatures

Question 6

What is SAS?

Answer 6

SAS is similar to access keys but allows you to customize your access.

Question 6

What are features you can configure using SAS?

Answer 6

RW/RO
Expire time
Allowed IP addresses
Protocols (HTTP or HTTPS)

Question 6

How dose SAS access work?

Answer 6

The SAS token will generate a URL and token for access (this will use of the access keys for this). This help limit access to your files rather than using URLs with no permissions.

Question 7

What is General Purpose v2?

Answer 7

This is the generally available default option used for any new storage accounts. It offers all data services with all options for replication and access tiers where available.

Question 8

What is General Purpose v1?

Answer 8

It provides all the data services like General Purpose v2 but does not have all the replication options or access tiers.

Question 9

What is premium block blob?

Answer 9

Premium storage account type for block blobs and append blobs. Recommended for scenarios with high transaction rates or that use smaller objects or require consistently low storage latency.

Question 10

What is premium file shares?

Answer 10

Premium storage account type for file shares only. Recommended for enterprise or high-performance scale applications.

Question 11

What is premium page blobs?

Answer 11

Premium storage account type for page blobs only.

Question 12

What is Azure Blobs?

Answer 12

Blobs are unstructured data such as image, text or binary data files

Question 13

What are the three types of Azure Blobs?

Answer 13

Block Blobs
Page Blobs
Append Blob

Question 14

What is Block Blobs?

Answer 14

Block Blobs are the default blob type used for file storage, great for static content, for example, image or text files. That are not likely to be updated frequently.

Question 15

What is Page Blobs?

Answer 15

Page Blobs are used for unmanaged VM disks. Page blobs were designed for storing disks images either as a template or active disk.

Question 16

What is Append Blob?

Answer 16

Append Blob are optimised for logging, this type of blob storage allows for additional information to be added to the blobs when additional information is appended to the files.

Question 17

What is Azure Files?

Answer 17

Azure Files allow you to setup SMB (Server Message Block) within your Azure subscription, this allows multiple VMs to access to the files at the same time.

Question 18

What is Azure Queue Service?

Answer 18

The Azure queues service is used for storing queue messages, which are up to 64KB in size. These are stored in the queue to be proceed one at a time. They are commonly used for PaaS (Platform-as-a-Service) that required message queues for processing data, like for websites or hosted applications.

Question 19

What are Tables used for?

Answer 19

Tables are used to store structed data in a NoSQL database. This is ideal for storing large amounts of data the you need access to quickly.

Question 20

What are the 4 types of storage replication

Answer 20

Locally redundant storage (LRS) Zone-redundant storage (LRS) Geo-redundant storage (GRS) Read-Access Geo-redundant storage (RA-GRS)

Question 21

What is Locally redundant storage (LRS)?

Answer 21

Synchronously replicates data to three disks within a data centre in the primary region. Offers a moderate level of availability at a lower cost.

Question 22

What is Zone-redundant storage (LRS)?

Answer 22

Synchronously replicates data among three Azure availability zones in the primary region. Provides a higher level of resilience at higher cost.

Question 23

What is Geo-redundant storage (GRS)?

Answer 23

Stores another three copies of data in a paired Azure region.

Question 24

What is Read-Access Geo-redundant storage (RA-GRS)?

Answer 24

Same as GRS, but allows data to be read from both Azure regions

Question 25

What are the 3 storage access tiers?

Answer 25

Hot Cool Archive

Question 26

What is the Hot access tier?

Answer 26

If the data is in use continually or accessed frequently it is the correct tier for your data, but it will cost more to store here due to how often you’re accessing the data

Question 27

What is the Cool access tier?

Answer 27

Cool tiers are designed for data less frequently accessed, stored for the short to medium term. This could be recent backups, DR information, or files read on a reduced frequency.

Question 28

What is the Archive access tier?

Answer 28

This tier is perfect for long-term backups and archived datasets that need to be kept but do not require immediate access. To access these blobs, they need to be converted back to hot or cold storage through the rehydration process. This can take up to 15 hours.

Question 29

Where do you customize network connections with storage accounts

Answer 29

Networking

Question 30

When doing a live migration what account storage replication options are supported?

Answer 30

LRS and GRS only If you use anything else in needs to be converted first before the live migration

Question 31

What is Managed identities?

Answer 31

This is a better alternative for developers who use secrets, credentials, certificates, and keys for secure communication between services.
