Question

Which of the following options are components of an instance type? (Select THREE.)

A. Memory
B. CPU
C. Public IP address
D. Application server software
E. Network performance
F. Operating system

Answer

A. Memory
B. CPU
E. Network performance

Explanation

The main components of an instance type are the CPU, memory, and network performance. The operating system and the application software are part of the Amazon Machine Image (AMI). The public IP address is part of the network settings.

An Amazon EC2 instance type defines the hardware capabilities and capacity of a virtual server in the cloud. The key components that specify an instance type are:

  1. Memory – The amount of RAM available to the instance. More memory allows the instance to run memory-intensive applications and support more concurrent users.
  2. CPU – The number, type, and speed of the instance’s virtual CPUs. Compute-intensive workloads require instances with more and faster CPUs.
  3. Network Performance – The maximum network bandwidth and packets per second (PPS) supported by the instance. Network-intensive applications need instances with high network performance.

The other options are not components of an instance type:

  • Public IP address is a separate resource assigned to an instance, not part of the instance type definition.
  • Application server software and the operating system are not hardware components, but rather the software stack running on an instance. The instance type specifies the underlying hardware capabilities.

So in summary, the key components that define an EC2 instance type and its performance characteristics are the memory, CPU, and network specs. Choosing the right instance type involves aligning these capabilities with your workload requirements.
