Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Destination: 0.0.0.0/0, Target: NAT Gateway

    Why this is correct

    Directing 0.0.0.0/0 to the NAT Gateway routes all outbound internet traffic through it.

  • Destination: 0.0.0.0/0, Target: Service Gateway

    Why it's wrong here

    Service gateway routes to Oracle regional services, not the internet.

  • Destination: 10.0.0.0/16, Target: Internet Gateway

    Why it's wrong here

    This routes internal VCN traffic to an internet gateway instead of NAT.

  • Destination: VCN CIDR, Target: NAT Gateway

    Why it's wrong here

    Internal VCN traffic does not go through a NAT Gateway.

Visual reference

Inside (Private) PC-A 10.0.0.1 PC-B 10.0.0.2 NAT Router Outside (Public) 203.0.113.1 Inside Global Server PAT: many private IPs share one public IP via unique port numbers
