The certification exam will measure the skills and knowledge of the candidates across seven different domains. The highlights of these areas are as follows:

Design, Plan, and Prototype GCP Networks

• Design Virtual Private Cloud: This section covers the individuals’ skills in peering, multiple versus single, shared or standalone, CIDR range for the subnets, and IP address. It also focuses on the concepts, such as routes, firewall, and the differences between other Cloud platforms and Google Cloud Networking;
• Design Overall Network Architectures: The consideration for this topic include alternatives for high availability, failover & disaster recovery plan, DNS strategy, container networking, hybrid connectivity, and optimizing for latency. The certification exam also requires competence in selecting the relevant load balancing options, meeting the business prerequisites, Micro-segmentation for security reasons, IAM & security, and understanding of the way quotas are applied based on project and VPC;
• Design Hybrid Networks: The questions from this subtopic will measure the expertise of the learners in peering options, IPsec VPN, using interconnects, cross-organization access, standalone versus shared VPC interconnect access, Cloud router, as well as failover & disaster recovery strategy.
