About PCNE
Networking on Google Cloud in depth: global VPCs and Shared VPC, Cloud Interconnect and HA VPN, Cloud Router and BGP, the load balancer family, Cloud DNS and network security controls.
Who it's for. Network engineers who design and run Google Cloud connectivity.
How to prepare
- Know every load balancer by layer, scope (global or regional) and proxy vs passthrough.
- Dedicated vs Partner Interconnect, and when HA VPN over Interconnect makes sense.
- Shared VPC vs VPC peering, including peering’s non-transitivity.
Sample PCNE questions
Try these with the answers on the page, then practise the full bank.
- A logistics firm pushes multi-terabyte nightly backups from its warehouse servers to Google Cloud and needs a private, high-throughput path that never touches the public internet. Which option fits? Configuring hybrid connectivity
- A batch-processing service makes thousands of simultaneous outbound API calls from a fleet of VMs that have no external IP addresses, and some calls fail with port exhaustion errors. Which Cloud NAT setting should the team adjust so each VM receives more source ports? Network security
- A financial services firm wants every packet leaving one spoke subnet to pass through a third-party deep-packet inspection appliance. The appliances run on several VMs that must scale out. Which construct lets the VPC steer traffic into that appliance pool? Designing and planning VPC networks
- A media archive holds roughly 40 TB of video that must reach Cloud Storage within about two weeks. The office uplink cannot move that volume in time. Which offering should the team evaluate for shipping the data on physical hardware? Configuring hybrid connectivity
- A manufacturer wants its on-premises core switches to share one extended LAN with its Google Cloud VPCs, so a legacy appliance can use a VLAN that spans both sides. The company will buy the link from a connectivity provider. Which attachment type fits? Configuring hybrid connectivity
- A real-time trading dashboard streams updates over WebSocket connections from browsers worldwide. The team wants a single global anycast entry point that understands HTTP so it can route requests by URL path. Which load balancer should front the dashboard? Load balancing
- An e-commerce cart service sits behind a global external Application Load Balancer and must keep each shopper pinned to one backend across requests. The team wants the load balancer to issue the affinity token itself rather than rely on the shopper's network address. Which session affinity setting should be selected? Load balancing
- A company uses Shared VPC. Service project administrators must manage firewall rules that protect only the instances their own team runs, and the host project must not grant broad network-wide control. How should this be implemented? Designing and planning VPC networks

Questions people ask
Is this PCNE practice exam free?
Yes. All 100 questions, the timed mock exam and the explanations are free, and there's no account to create.
Are these real exam questions?
No. Real exam questions are confidential under the Google Cloud candidate agreement. These are practice questions written to cover the same domains in the same scenario style, each with an explanation of why the answer is right.
How is the PCNE mock exam scored?
Questions are drawn from every domain in proportion to the exam guide, and you get a raw percentage with a breakdown by domain. Google Cloud uses scaled scoring, so treat 75% or more here as a sign you're ready rather than a predicted score.
