You have a virtual machine named VM1 that runs Windows Server 2016. VM1 is in the East US Azure region.
Which Azure service should you use from the Azure portal to view service failure notifications that can affect the availability of VM1?
A. Azure Service Fabric
B. Azure Monitor
C. Azure virtual machines
D. Azure Advisor
Correct Answer: C
Explanation/Reference:
In the Azure virtual machines page in the Azure portal, there is a named Maintenance Status. This column will display service issues that could affect your virtual machine. A service failure is rare but host server maintenance that could affect your virtual machines is more common.
Azure periodically updates its platform to improve the reliability, performance, and security of the host infrastructure for virtual machines. The purpose of these updates ranges from patching software components in the hosting environment to upgrading networking components or decommissioning hardware.

In addition, the page that is noted from question:
https://docs.microsoft.com/en-us/azure/virtual-machines/maintenance-and-updates
States:
The Azure platform starts live migration in the following scenarios:
Planned maintenance
Hardware failure
Allocation optimizations
Some planned-maintenance scenarios use live migration, and you can use Scheduled Events to know in advance when live migration operations will start.
Live migration can also be used to move VMs when Azure Machine Learning algorithms predict an impending hardware failure or when you want to optimize VM allocations. For more information about predictive modeling that detects instances of degraded hardware, see Improving Azure VM resiliency with predictive machine learning and live migration. *Live-migration notifications appear in the Azure portal in the Monitor and Service Health logs as well as in Scheduled Events if you use these services.*
A “service failure notification” is not planned maintenance! The core question is about service failures, so use Azure Monitor! Everyone seems to be hooked on to the same wrong answer from the AZ-900 exam question that is floating around…
B is correct
In the Azure portal: Home > Monitor > Service Health > Service Issues and you can select your Region from there.
Option B. The question is “Which Azure service …” Azure virtual machines are NOT a service.
Option C : Because “Once a planned maintenance wave is scheduled, you can check for a list of virtual machines that are impacted.”
Monitor will give the below details “Maintenance: A planned maintenance activity that might impact one or more of the resources under your subscription.”
So the answer is Option C
In my opinion C

B. Azure Monitor
