💡 Hint

Common Mistakes

Using a subnet or instance ID instead of a VPC ID.

Leaving the ID blank or using an incorrect format.

The id attribute must be the VPC ID. Only option A is a valid VPC ID format.

💡 Hint

Common Mistakes

Using 'name' or 'default' instead of 'current'.

Setting the attribute to false or omitting it.

The current attribute set to true tells Terraform to get the current region.

Fix the error in the code to query an existing AWS subnet by its filter.

💡 Hint

Common Mistakes

Using 'name' or 'subnet-name' which are not valid filter names.

Using 'subnet-id' which filters by ID, not tag.

To filter by a tag name, use tag:Name as the filter name.

Fill both blanks to query an existing AWS security group by its name and VPC ID.

Terraform

data "aws_security_group" "selected" {
  filter {
    name   = "[1]"
    values = ["my-security-group"]
  }
  filter {
    name   = "[2]"
    values = ["vpc-abc123"]
  }
}

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

💡 Hint

Common Mistakes

Using 'tag:Name' or 'name' instead of 'group-name' for the name filter.

Using 'name' instead of 'vpc-id' for the VPC filter.

Use group-name to filter by security group name and vpc-id to filter by VPC ID.

Terraform

data "aws_instances" "selected" {
  filter {
    name   = "[1]"

  }
  filter {
    name   = "[2]"
    values = ["running"]

  }
}

💡 Hint

Common Mistakes

Using 'state' instead of 'instance-state-name'.

Using 'Name' without 'tag:' prefix.

Using 'availability_zone' instead of 'availability-zone'.

Use tag:Name to filter by tag, instance-state-name for instance state, and availability-zone for zone.
