Which AWS subnet configuration correctly creates a private subnet?
A<code>AssignPublicIpOnLaunch: true</code>
B<code>EnableInternetGateway: true</code>
C<code>MapPublicIpOnLaunch: false</code>
D<code>RouteTable: 0.0.0.0/0 via IGW</code>
Step-by-Step Solution
Solution:

  1. Step 1: Identify private subnet IP assignment

    Private subnets do not assign public IPs automatically, so MapPublicIpOnLaunch must be false.

  2. Step 2: Understand routing and gateway settings

    Internet Gateway (IGW) and routing to 0.0.0.0/0 are for public subnets, not private.

  3. Final Answer:

    <code>MapPublicIpOnLaunch: false</code> -> Option C

  4. Quick Check:

    Private subnet = no public IP assignment [OK]
Quick Trick: Private subnet disables public IP assignment [OK]
Common Mistakes:
MISTAKES
  • Setting public IP assignment to true for private subnet
