PCNE Implementing a Virtual Private Cloud Practice Question

Answer analysis

Option-by-option breakdown

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

• ✓

  Create a Cloud Router in the region, then create a Cloud NAT gateway using that router, then assign static IP addresses to the NAT, then apply the NAT to the desired subnets, then test connectivity from a private instance.

  Why this is correct

  This order follows the logical dependency: Cloud Router must exist before creating the NAT; NAT must exist before assigning IPs; NAT must be applied to subnets before testing. It ensures all prerequisites are met and the configuration works correctly.

• ✗

  Create a Cloud NAT gateway first, then create a Cloud Router, then assign IP addresses, then apply to subnets, then test connectivity.

  Why it's wrong here

  Incorrect because a Cloud Router is required when creating a Cloud NAT. Creating the NAT first will fail as no router is specified.

• ✗

  Create a Cloud Router, then assign IP addresses to the NAT, then create the Cloud NAT, then apply to subnets, then test.

  Why it's wrong here

  Incorrect because you cannot assign IP addresses to a NAT gateway before it is created. IP assignment is part of NAT configuration.

• ✗

  Create a Cloud Router, then create a Cloud NAT and apply it to subnets, then assign IP addresses, then test connectivity.

  Why it's wrong here

  Incorrect because applying the NAT to subnets before assigning IP addresses may result in the NAT using ephemeral IPs instead of the desired static ones. The recommended order is to assign IPs before applying to subnets.
