Why VMs provide compute flexibility in Azure - Quick Recap

Recall & Review

What is a Virtual Machine (VM) in cloud computing?

A VM is a software computer that runs an operating system and applications just like a physical computer, but it runs inside a cloud environment, allowing easy setup and management.

How do VMs provide compute flexibility?

VMs let you quickly change the size, power, and number of virtual computers to match your needs without buying physical hardware.

Why is scaling important in VMs?

Scaling means adjusting resources like CPU and memory up or down. VMs allow easy scaling to handle more or less work, saving cost and improving performance.

What role does VM image play in flexibility?

VM images are templates that let you create many VMs with the same setup quickly, helping you deploy consistent environments fast.

How does VM isolation contribute to flexibility?

Each VM runs separately, so you can run different operating systems or apps on the same physical server without conflicts.

What allows a VM to adjust its resources like CPU and memory easily?

A Fixed resource allocation

B Physical hardware upgrades

C Virtualization technology

D Manual software installation

Virtualization technology enables VMs to change resource allocation quickly without physical hardware changes.

Which feature of VMs helps deploy multiple identical environments quickly?

A VM images

B Manual configuration

C Physical servers

D Network switches

VM images are templates used to create many VMs with the same setup fast.

Why is VM isolation important?

A It merges all VMs into one system

B It allows running different OS or apps on the same hardware safely

C It limits VM network access

D It slows down VM performance

Isolation keeps VMs separate so they don’t interfere, allowing different OS or apps on one physical server.

What does scaling a VM mean?

A Installing new software

B Turning it off permanently

C Deleting the VM image

D Changing its resource size like CPU or memory

Scaling means adjusting VM resources to meet workload needs.

Which is NOT a benefit of using VMs for compute flexibility?

A Instant hardware replacement

B Quick resource adjustment

C Multiple OS support

D Rapid deployment

VMs do not replace physical hardware instantly; they virtualize resources on existing hardware.

Explain how VMs provide compute flexibility in cloud environments.

Think about how VMs let you adjust power and create copies easily.

Describe the benefits of VM isolation for running different applications.

Consider how keeping things separate helps avoid problems.
