Microsoft Azure Fundamentals: Describe Azure Architecture and Services
What are the two types of subscription boundaries?
- Billing Boundary - Access Control Boundary
What are the three common reasons a business would create additional Azure subscriptions?
- Environments - Organizational Structure - Billing
What three things are included in a free student Azure Account
- Free access to certain services for 12 months - A credit to be used in 12 months - Access to certain dev tools for 12 months
What three things are included in a free Azure account
- Free access to popular Azure products for 12 months - A credit to be used in the first 30 days - Access to Azure services that are always free.
Azure services that support availability zone falls into what three categories?
- Zonal Services - Zone-redundant services - Non-regional services
How many management groups can be supported in a single directory?
10,000
What is a datacenter?
A facility the stores resources arranged in racks with dedicated power, cooling and network connectivity.
What is an Azure resource group?
A group of azure resources.
What is an Azure management group?
A logical container that allows admins to manage access, policy and compliance across multiple Azure subscriptions.
True or False: When you create a resource you are not required to put it in a resource group.
False
How many availability zones are typically in an availability zone-enabled region?
Three
Lis the hierarchy of resource groups, subscriptions, and management groups.
Top to Bottom - Root Management Group - Management Groups - Subscriptions - Resource Groups - Resources
True or False: A resource group can contain many resources, but a resource can only belong to one resource group.
True
True or False: An Azure account can have multiple subscriptions.
True
True or False: Azure accounts also serve as identities in Azure AD.
True
True or False: Azure resources are created within an Azure subscription.
True
True or False: Each management group and subscription can only support one parent.
True
True or False: When you delete a resource group, all the resources within the resources group will be deleted.
True
True or False: When you grant or deny access to a resource group, you are granting/ denying access to all the resources within a resource group.
True
True or False: When you move a resource to a new group it will no longer be associated with the former group.
True
True or False: You can use subscriptions to define boundaries around Azure products, services, and resources.
True
True or False: You need an Azure subscription to create and use Azure services.
True
True or False? Can management groups be nested?
True
What is an Azure Region Pair?
Two Azure regions within the same geography located at least 300 miles apart.
What is an Azure Resource?
Anything that can be created, deployed or provisioned.
What is a benefit of Azure region pairs?
Allows for replication of resources across a geography ehich decreases the likelihood of experiencing interruptions due to major events like natural disasters, civil unrest, power outages, etc.
What is an Azure Availability Zone?
An Azure Availability zone are physically separate datacenters within an Azure region.
What is an Azure region?
An azure region is a geographical area on the planet that contains one, but possible multiple data centers located nearby and networked together on a low-latency network.
What is a Sovereign Region?
An instance of Azure separated from the main instance of Azure. Could possibly be for compliance or legal purposes.
True or False: When you apply an action to a resource group, the action will not apply to the resources within the resource group.
False
What is latency?
Determine the level of lag.
True or False: Resources can be nested.
False
What is non-regional services?
Services are always available from Azure geographies and are resilient to zone-wide outages as well as region-wide outages.
How can Azure RBAC be useful in management groups?
Since a management group can have multiple subscriptions within it, you can use Azure RBAC to define what users have access to. Being that this is applied at a management level, permissions will be applied to all the resources within the hierarchy.
How many levels of depth can a management tree support, not including the root management group?
Six
What is zone-redundant services?
The platform replicates automatically across zones.
What is the Billing Boundary?
This type of subscription boundary focuses on how an account is billed. Since Azure creates a separate billing report/ invoice per subscription.
What is the Access Control Boundary?
This type of subscription boundary focusing on the access management policies reflecting different organizational structures.
What is zonal services?
You pin the resource to a specific zone.
