How does Compute Engine support scaling VM resources over time?

You can resize VMs by changing CPU and memory without downtime, adapting to changing workload demands.

What feature allows you to pick exact CPU and memory sizes in Compute Engine VMs?

A Custom machine types

B Predefined machine types

C Managed instance groups

D Persistent disks

Custom machine types let you specify exact CPU and memory amounts for your VM.

Which storage option provides the fastest performance for Compute Engine VMs?

A Coldline Storage

B Standard HDD

C Network File System

D Local SSD

Local SSDs offer the fastest storage performance for VMs.

How can you change VM resources like CPU and memory after creation without downtime?

A Delete and recreate VM

B Use a different zone

C Resize the VM

D Change storage type

Compute Engine allows resizing VMs to adjust CPU and memory without downtime.

What is a benefit of predefined machine types in Compute Engine?

A They provide common CPU and memory combos for quick setup

B They allow unlimited CPU cores

C They automatically scale storage

D They are free to use

Predefined machine types offer common resource combinations for easy VM creation.

Why is VM flexibility important in cloud computing?

A To make VMs slower

B To avoid paying for unused resources

C To limit storage options

D To prevent scaling

Flexibility helps you pay only for the resources you actually need.
