💡 Hint

Common Mistakes

Choosing 'self_managed' which requires manual management.

Choosing 'fargate' which is serverless, not a node group.

Choosing 'lambda' which is unrelated to node groups.

The managed node group is created and managed by AWS for EKS clusters.

Complete the code to create a self-managed node group using EC2 instances.

AWS

ec2.create_instances({ 'InstanceType': '[1]', 'MinCount': 1, 'MaxCount': 3 })

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

💡 Hint

Common Mistakes

Using 'fargate' which is serverless and not an instance type.

Using 'managed' which is a node group type, not an instance type.

EC2 instance types like t2.micro are used for self-managed node groups.

Fix the error in the Fargate profile creation code by completing the missing field.

AWS

eks.create_fargate_profile(clusterName='myCluster', fargateProfileName='[1]', podExecutionRoleArn=role_arn, selectors=[{'namespace': 'default'}])

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

💡 Hint

Common Mistakes

Using node group types as profile names.

Using unrelated terms like 'lambdaProfile'.

The Fargate profile name should be a descriptive string like defaultProfile.

Fill both blanks to define a managed node group with a specific instance type and desired capacity.

AWS

eks_cluster.add_nodegroup(instance_types=['[1]'], desired_capacity=[2])

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

💡 Hint

Common Mistakes

Using invalid instance types.

Setting desired capacity to a string instead of a number.

The instance type t3.medium is valid and the desired capacity 3 sets the number of nodes.

5fill in blank

hard

Fill all three blanks to create a Fargate profile with a namespace selector and a profile name.

AWS

eks.create_fargate_profile(clusterName='myCluster', fargateProfileName='[1]', podExecutionRoleArn=role_arn, selectors=[{'namespace': '[2]'}], subnets=['[3]'])

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

💡 Hint

Common Mistakes

Using node group types as profile names.

Using invalid subnet IDs.

Leaving namespace blank or incorrect.

The profile name fargateProfile1, namespace default, and subnet ID subnet-123abc are valid values for creating a Fargate profile.
