Explanation:
Composite SLAs involve multiple services supporting an application, each with differing levels of availability. For example,
consider an App Service web app that writes to Azure SQL Database. At the time of this writing, these Azure services have
the following SLAs:
App Service web apps = 99.95%

SQL Database = 99.99%

What is the maximum downtime you would expect for this application? If either service fails, the whole application fails. The
probability of each service failing is independent, so the composite SLA for this application is 99.95% 99.99% = 99.94%.
That's lower than the individual SLAs, which isn't surprising because an application that relies on multiple services has more
potential failure points.

Answer:

Explanation:
If the SLA for an Azure service is not met, you receive credits for that service and that service only. The credits are deducted
from your monthly bill for that service. If you stopped using the service where the SLA was not met, your account would
remain in credit for that service. The credits would not be applied to any other services that you may be using.
Service Credits apply only to fees paid for the particular Service, Service Resource, or Service tier for which a Service Level
has not been met. In cases where Service Levels apply to individual Service Resources or to separate Service tiers, Service
Credits apply only to fees paid for the affected Service Resource or Service tier, as applicable. The Service Credits awarded
in any billing month for a particular Service or Service Resource will not, under any circumstance, exceed your monthly
service fees for that Service or Service Resource, as applicable, in the billing month.

Box 1: Yes
Microsoft guarantee at least 99.9% availability of the Azure Active Directory Premium edition services. The services are
considered available in the following scenarios:
Users are able to login to the service, login to the Access Panel, access applications on the Access Panel and reset

passwords.
IT administrators are able to create, read, write and delete entries in the directory or provision or de-provision users to

applications in the directory.
Box 2: No
No SLA is provided for the Free tier of Azure Active Directory.
Box 3: Yes
You can claim credit if the availability falls below the SLA. The amount of credit depends on the availability. For example:
You can claim 25% credit if the availability is less than 99.9%, 50% credit for less than 99% and 100% for less than 95%
availability.

Answer:

Explanation:
When a virtual machine is stopped (deallocated), the virtual machine is unloaded/dismounted from the physical server in
Azure. In this state, you are not charged for the virtual machine itself. However, you are still charged for the storage costs of
the virtual hard disks attached to the virtual machine.
If the virtual machine is stopped but not deallocated (this happens if you shut down the virtual machine from the operating
system of the virtual machine), the virtual machine is still mounted on the physical server in Azure and you are charged for
the virtual machine itself as well as the storage costs. To ensure that a virtual machine is stopped (deallocated), you need
to stop the virtual machine in the Azure portal.
