AZ-204 Developing for Microsoft Azure Exam Prep - Virtual Machine Scale Sets

The video tutorial explains how to scale applications running on virtual machines using Microsoft's virtual machine scale sets. It covers the creation process, including naming, subscription, and resource group setup. The tutorial highlights the benefits of auto scaling, such as setting scaling rules based on performance or schedule. It also discusses low priority mode for cost savings and the concept of placement groups for distributing virtual machines. The main focus is on the auto scaling features, which allow for dynamic scaling based on CPU usage or time schedules.

What is one of the primary functions of a virtual machine scale set?

• To provide a single virtual machine with enhanced performance

• To offer a group of identical virtual machines with load balancing

• To reduce the cost of app services

• To replace physical servers with cloud storage

What is the maximum number of virtual machines supported in a single placement group?

• 100

• 50

• 500

• 1000

What is a key benefit of using low priority mode in virtual machine scale sets?

• Guaranteed availability of virtual machines

• Enhanced security features

• Reduced cost when machines are not in high demand

• Increased performance during peak hours

How can auto-scaling be configured in a virtual machine scale set?

• By setting a fixed number of virtual machines

• By using third-party software

• By adjusting based on CPU usage and time schedules

• By manually adding or removing virtual machines

What is the cost implication of using a virtual machine scale set?

• There is an additional cost for the scale set itself

• You pay a flat rate regardless of usage

• You only pay for the instances you use

• It is free of charge
