AZ-204 Developing for Microsoft Azure Exam Prep - Scaling a Single Virtual Machine

The video tutorial explains how to manage and scale virtual machines (VMs) using Microsoft's VM scale sets and other methods. It covers resizing standalone VMs, the potential disruptions involved, and alternative strategies like setting up new VMs or using load balancers. Automation through ARM templates and PowerShell scripting is also discussed as a way to efficiently manage scaling operations.

What is a potential downside of resizing a standalone virtual machine?

• It requires no downtime.

• It improves performance instantly.

• It can cause disruption to users.

• It is cost-effective.

What is one method to handle an overloaded virtual machine without resizing it?

• Increase the CPU limit.

• Set up a new, larger virtual machine and redirect traffic.

• Reduce the number of users.

• Install additional software.

What is the role of a load balancer in managing virtual machines?

• It reduces the cost of VMs.

• It distributes incoming traffic across multiple VMs.

• It automatically upgrades VMs.

• It increases the CPU speed.

How can automation help in scaling virtual machines?

• By automatically detecting high CPU usage and deploying new VMs.

• By increasing the cost efficiency.

• By reducing the number of VMs.

• By manually adjusting VM sizes.

What is a potential issue when modifying a virtual machine in progress?

• It will automatically balance the load.

• It could result in a reboot, causing disruption.

• It may cause the VM to become more efficient.

• It can lead to increased costs.
