1Z0-1072-26 Networking Practice Question

An administrator wants to ensure that a compute instance in a private subnet can communicate with other compute instances in a peered VCN, but cannot initiate outbound connections to the internet. Which combination of components correctly satisfies this requirement?

Answer choices

Why each option matters

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

Correct answer & explanation

Local Peering Gateway (or DRG) and route table rules pointing to the peer VCN CIDR, with no NAT or Internet Gateway.

To allow peering without internet access, you need a peering connection (LPG or DRG) and proper route table rules pointing to the peer. You should omit any Internet Gateway or NAT Gateway to prevent internet access.

Answer analysis

Option-by-option breakdown

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

  • Local Peering Gateway (or DRG) and route table rules pointing to the peer VCN CIDR, with no NAT or Internet Gateway.

    Why this is correct

    Peering without an Internet or NAT Gateway allows VCN-to-VCN communication while blocking the internet.

  • NAT Gateway and a route table pointing 0.0.0.0/0 to the peer VCN.

    Why it's wrong here

    A NAT gateway provides internet access, violating the restriction.

  • Service Gateway pointing to the peered VCN CIDR.

    Why it's wrong here

    Service Gateways only connect to the Oracle Services Network, not peered VCNs.

  • Internet Gateway attached to the private subnet route table.

    Why it's wrong here

    An Internet Gateway gives direct internet access to instances.
