Describe the core architectural components of Azure

Question 1

What is a requirement to use an azure service?

Answer 1

An account with an azure subscription.

Question 2

What PowerShell command is used to determine the version of azure CLI is in use?

Answer 2

az version.

Question 3

What PowerShell command is used to switch to BASH CLI?

Answer 3

bash

Question 4

What powershell command initializes the CLI interactive mode in azure?

Answer 4

az interactive

Question 5

What is an azure region?

Answer 5

Geographical area on the planet that contains at least one, but potentially multiple datacenters that are nearby and networked together.

Question 6

What is an azure availability zone?

Answer 6

Physically separate datacenters within an Azure region.

Question 7

How are availability zones isolated?

Answer 7

Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking.

Question 8

How does azure ensure resiliency within a region?

Answer 8

A minimum of three separate availability zones are present in all availability zone-enabled regions.

Question 9

Do all azure regions support availability zones?

Answer 9

No.

Question 10

What services/applications are able to leverage availability zones?

Answer 10

VMs, managed disks, load balancers, and SQL databases.

Question 11

What are the 3 types of availability zone services?

Answer 11

1. Zonal services
2. Zone-redundant services
3. Non-regional services

Question 12

Define a ‘Zonal’ availability service

Answer 12

You pin the resource to a specific zone (for example, VMs, managed disks, IP addresses).

Question 13

Define a ‘Zone-redundant’ availability service

Answer 13

The platform replicates automatically across zones (for example, zone-redundant storage, SQL Database).

Question 14

Define a ‘Non-regional’ availability service

Answer 14

Services are always available from Azure geographies and are resilient to zone-wide outages as well as region-wide outages.

Question 15

How does azure ensure resiliency between regions?

Answer 15

Region pairs; Most Azure regions are paired with another region within the same geography.

Question 16

What is the purpose/function of a region pair?

Answer 16

Allows for the replication of resources across a geography that helps reduce the likelihood of interruptions that may affect a region.

Question 17

Do all azure services automatically replicate or provide failover to a different zone/region?

Answer 17

No, in some cases the tenant must configure replication/redundancy.

Question 18

How do region pairs help with maintenance of azure?

Answer 18

Planned Azure updates are rolled out to paired regions one region at a time to minimize downtime.

Question 19

Define a ‘sovereign region’

Answer 19

Instances of Azure that are isolated from the main instance of Azure.

Question 20

What are examples of a sovereign region?

Answer 20

US DoD Central, US Gov Virginia, US Gov Iowa, China East, China North, etc.

Question 21

Define a ‘resource group’

Answer 21

Groupings of resources.

Question 22

Can a resource be in multiple resource groups?

Answer 22

No, a single resource can only be in one resource group at a time.

Question 23

Can resource groups be nested?

Answer 23

No, resource groups can’t be nested, meaning you can’t put resource group B inside of resource group A.

Question 24

What is the purpose of a resource group?

Answer 24

To make it easier to perform an action to multiple resources that are similar.

Question 25

What is the purpose of an azure subscription?

Answer 25

Provides authenticated and authorized access to Azure products and services to provision resources.

Question 26

What are the two ways azure subscriptions can define boundaries around Azure products, services, and resources?

Answer 26

1. Billing boundary
2. Access control boundary

Question 27

Define a ‘billing boundary’

Answer 27

Subscription type determines how an Azure account is billed for using Azure.

Question 28

Define an ‘Access control boundary’

Answer 28

Azure applies access-management policies at the subscription level, and you can create separate subscriptions to reflect different organizational structures.

Question 29

How can subscriptions be used to create separate environments?

Answer 29

Create subscriptions to set up separate environments for development and testing, security, or to isolate data for compliance reasons.

Question 30

How can subscriptions be used to create role based access?

Answer 30

You can create subscriptions to reflect different organizational structures allowing different levels of access to certain resources.

Question 31

What is the purpose of an azure management group?

Answer 31

To help organize subscriptions and apply governance conditions to subscriptions within a management group.

Question 32

What is the outcome of a subscription being assigned to a management group?

Answer 32

All subscriptions within a management group automatically inherit the conditions applied to the management group.

Question 33

What is the maximum amount of management groups that can be supported in a single directory?

Answer 33

10,000 management groups.

Question 34

What is the maximum depth that a management group tree can support?

Answer 34

A management group tree can support up to six levels of depth. This limit doesn’t include the root level or the subscription level.

Question 35

Can management groups and subscriptions have multiple parents?

Answer 35

Each management group and subscription can support only one parent.
