Question 3 Topic 7, Describe Azure cost management and Service Level Agreements

You have an Azure application that uses the services shown in the following table.

How should you calculate the composite SLA for the application?

  • A. 0.999 * 0.9999 = 0.9989001 = 99.89001%
  • B. 0.999 / 0.9999 = 0.9991 = 99.91%
  • C. Max(0.999, 0.9999) = 0.9999 = 99.99%
  • D. Min(0.999, 0.9999) = 0.999 = 99.9%
Answer:

A

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.

Question 6 Topic 7, Describe Azure cost management and Service Level Agreements

HOTSPOT
To complete the sentence, select the appropriate option in the answer area.
Hot Area:

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.
