PCNE Exam Syllabus

The Google Cloud Certified Professional Cloud Network Engineer Exam assesses the candidate’s competencies in five key subject areas.

Designing, planning, and prototyping a Google Cloud network

As a Cloud Network Engineer, it is essential to initiate the Google Cloud network infrastructure design process by conducting a thorough high-level analysis and crafting a comprehensive blueprint for the network framework. Optionally, this phase can involve the prototyping of potential design alternatives. The section presents several key factors to consider, including high availability, failover mechanisms, disaster recovery strategies, DNS approaches, and load balancing considerations.

  • Designing an overall network architecture
High availability, failover, and disaster recovery strategies
    DNS strategy (e.g., on-premises, Cloud DNS)
    Security and data exfiltration requirements
    Load balancing
    Applying quotas per project and per VPC
    Hybrid connectivity (e.g., Google private access for hybrid connectivity)
    Container networking
    IAM roles
    SaaS, PaaS, and IaaS services
    Microsegmentation for security purposes (e.g., using metadata, tags, service accounts)
  • Designing Virtual Private Cloud (VPC) instances
 P address management and bring your own IP (BYOIP)
 Standalone vs. Shared VPC
 Multiple vs. single
 Regional vs. multi-regional
 VPC Network Peering
 Firewalls (e.g., service account-based, tag-based)
 Custom routes
Using managed services (e.g., Cloud SQL, Memorystore)
Third-party device insertion (NGFW) into VPC using multi-NIC and internal load balancer as a next hop or equal-cost multi-path (ECMP) routes
  • Designing a hybrid and multi-cloud network
    Dedicated Interconnect vs. Partner Interconnect
    Multi-cloud connectivity
    Direct Peering
    IPsec VPN
    Failover and disaster recovery strategy
    Regional vs. global VPC routing mode
    Accessing multiple VPCs from on-premises locations (e.g., Shared VPC, multi-VPC
peering topologies)
    Bandwidth and constraints provided by hybrid connectivity solutions
    Accessing Google Services/APIs privately from on-premises locations
    IP address management across on-premises locations and cloud
    DNS peering and forwarding
  • Designing an IP addressing plan for Google Kubernetes Engine.
   Public and private cluster nodes
   Control plane public vs. private endpoints
   Subnets and alias IPs
   RFC 1918, non-RFC 1918, and privately used public IP (PUPI) address options
