AZ-104: Microsoft Azure Administrator Full Course - Maintenance and Availability

The video tutorial discusses three scenarios that can impact Azure virtual machines: unplanned hardware maintenance, unexpected downtime, and planned maintenance. Unplanned hardware maintenance involves live migration to prevent failure, while unexpected downtime includes auto healing to restore service. Planned maintenance involves periodic updates to enhance reliability and performance without affecting virtual machines.

What is the primary method Azure uses to handle unplanned hardware maintenance?

• Backing up data to the cloud

• Shutting down the virtual machine

• Live migration to a healthy machine

• Rebooting the virtual machine

Which of the following is NOT a cause of unexpected downtime?

• Local network failures

• Local disk failures

• Scheduled software updates

• Rack level failures

During the auto-healing process, what might happen to a virtual machine?

• It experiences no downtime

• It may lose a temporary drive

• It is permanently deleted

• It is moved to a different data center

What is the main goal of planned maintenance in Azure?

• To reduce the cost of cloud services

• To improve platform reliability, performance, and security

• To increase the number of virtual machines

• To update virtual machine operating systems

Who is responsible for updating the operating system and software of virtual machines in Azure?

• The user

• Microsoft

• Third-party vendors

• Automated scripts
