Instance types and families in AWS - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the instance type for an EC2 instance.

AWS

resource "aws_instance" "example" {
  ami           = "ami-12345678"
  instance_type = "[1]"
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the AMI ID instead of the instance type.

Using a region or VPC ID instead of the instance type.

The instance_type field defines the EC2 instance size and family, such as t2.micro.

2fill in blank

medium

Complete the code to select a compute-optimized instance family.

AWS

resource "aws_instance" "compute_optimized" {
  ami           = "ami-87654321"
  instance_type = "[1]"
}

Drag options to blanks, or click blank then click option'

Ar5.xlarge

Bm5.large

Ct3.micro

Dc5.large

Attempts:

💡 Hint

Common Mistakes

Choosing a general purpose or memory-optimized instance instead of compute-optimized.

Confusing instance families by their letter prefixes.

The c5.large instance type belongs to the compute-optimized family, designed for CPU-intensive tasks.

3fill in blank

hard

Fix the error in the instance type to use a valid memory-optimized instance.

AWS

resource "aws_instance" "memory_optimized" {
  ami           = "ami-11223344"
  instance_type = "[1]"
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using compute-optimized or general purpose instance types instead of memory-optimized.

Choosing an invalid instance type string.

The r5.large instance type is part of the memory-optimized family, suitable for memory-intensive applications.

4fill in blank

hard

Fill both blanks to define a burstable instance with the smallest size.

AWS

resource "aws_instance" "burstable" {
  ami           = "ami-55667788"
  instance_type = "[1].[2]"
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'm5' which is general purpose instead of burstable.

Choosing 'small' size instead of 'micro' for smallest instance.

The smallest burstable instance type is t3.micro, combining the family 't3' and size 'micro'.

5fill in blank

hard

Fill all three blanks to create a general purpose instance with medium size and the latest generation.

AWS

resource "aws_instance" "general_purpose" {
  ami           = "ami-99887766"
  instance_type = "[1][2].[3]"
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'large' size instead of 'medium'.

Using wrong family letter or generation number.

The latest generation general purpose instance is m5.medium, combining family 'm', generation '5', and size 'medium'.
