Option-by-option breakdown

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

• ✓

  Configure private services access on the VPC network, then create the Cloud SQL for MySQL instance with a private IP address, then connect from a Compute Engine VM in the same VPC.

  Why this is correct

  This is the correct order because the VPC must have private services access enabled to allow the Cloud SQL instance to receive a private IP within that VPC; then the instance is created with that private IP; finally, a Compute Engine VM in the same VPC can connect using the private IP.

• ✗

  Create the Cloud SQL for MySQL instance with a private IP address, then configure private services access on the VPC network, then connect from a Compute Engine VM in the same VPC.

  Why it's wrong here

  This sequence fails because private services access must be established before any Cloud SQL instance can receive a private IP in a VPC. When you attempt to create the instance first, the service networking connection (which allocates an IP range and sets up a VPC peering to the Cloud SQL service producer) does not yet exist, so Cloud SQL cannot allocate an internal address and the creation request will fail. In addition, the Compute Engine VM connection step would likewise be impossible because the instance would never have been created in this erroneous order.

• ✗

  Connect from a Compute Engine VM in the same VPC, then configure private services access on the VPC network, then create the Cloud SQL for MySQL instance with a private IP address.

  Why it's wrong here

  This order is invalid because connecting from a Compute Engine VM presupposes that both the Cloud SQL instance and its private IP already exist and are accessible over the established networking path. Placing the connection step first is logically impossible: there is no database endpoint to resolve or reach, and the VM would simply time out or receive a name resolution error. Even if private services access were configured afterward, that does not retroactively create the instance—the instance creation must precede any successful client connection, making this an entirely scrambled workflow.

• ✗

  Configure private services access on the VPC network, then connect from a Compute Engine VM in the same VPC, then create the Cloud SQL for MySQL instance with a private IP address.

  Why it's wrong here

  This option correctly starts with private services access, but it jumps to the connection step before the Cloud SQL instance exists. Without a provisioned instance, there is no private IP address, no DNS name, and no endpoint for the Compute Engine VM to contact, so the connection attempt will fail. The only viable path after configuring private services access is to create the Cloud SQL for MySQL instance with a private IP, and only then can the VM connect; skipping the instance creation step makes the entire sequence nonfunctional.
