Consider this parameter:

"Parameters": {"SubnetIds": {"Type": "List"}}

If a user inputs subnet-12345,subnet-67890, what type of value will SubnetIds hold?

AA list/array of subnet ID strings

BA single string with comma-separated subnet IDs

CAn integer count of subnets

DA boolean indicating if subnets exist

Step-by-Step Solution

Solution:

Step 1: Understand List parameter types in CloudFormation
List types split comma-separated input into an array of strings.
Step 2: Analyze the input and expected parameter value
Input "subnet-12345,subnet-67890" becomes a list with two subnet ID strings.
Final Answer:
A list/array of subnet ID strings -> Option A
Quick Check:
List parameter input = array of strings [OK]

Quick Trick: List types split comma-separated input into arrays [OK]
