AWS Solutions Architect Associate (SAA-C02) Exam Prep Course - 2021 UPDATED! - Auto Scaling Groups

The video tutorial explains the concept of auto scaling groups, which are collections of instances with similar characteristics that can be scaled based on specific criteria like CPU utilization and network throughput. It highlights the importance of replacing unhealthy instances and planning for the time it takes to launch new servers. The tutorial also covers the significance of spanning availability zones to ensure redundancy and discusses the need to define minimum instances to maintain performance. Proper planning and understanding of metrics are emphasized to meet scaling needs effectively.

What is the primary purpose of an auto scaling group?

• To manage user access

• To monitor application performance

• To group similar instances for scaling

• To replace network hardware

Which of the following is NOT a metric used to determine scaling in auto scaling groups?

• Free memory

• Network throughput

• CPU utilization

• Disk space

Why is it important for an auto scaling group to span multiple availability zones?

• To increase CPU utilization

• To reduce costs

• To improve user access

• To ensure application redundancy

What should be clearly specified when building an auto scaling group?

• The minimum number of running instances

• The software version

• The type of network hardware

• The maximum number of users

What is a key consideration before implementing any auto scaling?

• The location of the data center

• The color of the server racks

• Having a well-defined scaling plan

• The brand of the CPU
