PCNE Configuring Network Services Practice Question

A company is running workloads on Compute Engine instances without public IP addresses. They need to allow these instances to securely access the internet for software updates. Which Google Cloud service should be configured?

⚠ Common exam trap

Google Cloud often tests the distinction between Private Google Access (which only reaches Google APIs) and Cloud NAT (which provides full internet access), causing candidates to confuse the two when the requirement is for general internet connectivity like software updates.

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

Cloud NAT

Cloud NAT (Network Address Translation) allows Compute Engine instances without public IP addresses to initiate outbound connections to the internet for tasks like software updates. It translates the private IP addresses of the instances to a public IP address managed by Google Cloud, enabling secure outbound internet access without exposing the instances to inbound traffic.

Answer analysis

Option-by-option breakdown

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

  • Cloud VPN

    Why it's wrong here

    Cloud VPN is for connecting on-premises networks to Google Cloud, not for internet access.

  • Private Google Access

    Why it's wrong here

    Private Google Access only allows access to Google APIs, not general internet.

  • Cloud NAT

    Why this is correct

    Cloud NAT enables outbound internet traffic from instances without public IPs.

  • VPC Peering

    Why it's wrong here

    VPC peering connects two VPCs, not for internet access.

Visual reference
