• Clusters with shared VPC
• Private clusters
• Cluster network policy
• Adding authorized networks for cluster master access

Configuring and managing firewall rules. Considerations include:

• Network protocols
• Firewall logs
• Target network tags and service accounts
• Ingress and egress rules
• Priority

3. Configuring network services

Configuring load balancing. Considerations include:

• Network load balancer
• TCP and SSL proxy load balancers
• Firewall and security rules
• Internal load balancer
• HTTP(S) load balancer: including changing URL maps, backend groups, health checks, CDN, and SSL certs
• Capacity scaling
• Session affinity
• Creating backend services

Configuring Cloud CDN. Considerations include:

• Signed URLs
• Enabling and disabling Cloud CDN
• Cache invalidation
• Using cache keys

Configuring and maintaining Cloud DNS. Considerations include:

• Migrating to Cloud DNS
• Internal DNS
• Managing zones and records
• DNS Security (DNSSEC)
• Global serving with Anycast
• Cloud DNS
• Integrating on-premises DNS with GCP

Enabling other network services. Considerations include:

• Canary (A/B) releases
• Health checks for your instance groups
• Enabling private API access
• Distributing backend instances using regional managed instance groups

4. Implementing hybrid interconnectivity

Configuring interconnect. Considerations include:

• Bulk storage uploads
• Partner (e.g., layer 2 vs. layer 3 connectivity)
• Virtualizing using VLAN attachments

Configuring a site-to-site IPsec VPN (e.g., route-based, policy-based, dynamic or static routing).

Configuring Cloud Router for reliability.

5. Implementing network security

Configuring identity and access management (IAM). Tasks include:

• Defining custom IAM roles
• Using pre-defined IAM roles (e.g., network admin, network viewer, network user)
• Assigning IAM roles to accounts or Google Groups
• Viewing account IAM assignments

Configuring Cloud Armor policies. Considerations include:

• IP-based access control

Configuring third-party device insertion into VPC using multi-nic (NGFW)

Managing keys for SSH access

6. Managing and monitoring network operations

Logging and monitoring with Stackdriver or GCP Console

Managing and maintaining security. Considerations include:

• Firewalls (e.g., cloud-based, private)
• Diagnosing and resolving IAM issues (shared VPC, security/network admin)

Maintaining and troubleshooting connectivity issues. Considerations include:

• Cross-connect handoff for interconnect
• Draining and redirecting traffic flows
• Monitoring ingress and egress traffic using flow logs
• Managing and troubleshooting VPNs
• Monitoring firewall logs
• Identifying traffic flow topology (e.g., load balancers, SSL offload, network endpoint groups)
• Troubleshooting Cloud Router BGP peering issues

Monitoring, maintaining, and troubleshooting latency and traffic flow. Considerations include:

Network throughput and latency testing Routing issues Tracing traffic flow

7. Optimizing network resources

Optimizing traffic flow. Considerations include:

• Expanding subnet CIDR ranges in service
• Load balancer and CDN location
• Global vs. regional dynamic routing
• Accommodating workload increases (e.g., autoscaling vs. manual scaling)

Optimizing for cost and efficiency. Considerations include:

• VPN vs. interconnect
• Automation
• Cost optimization (Network Service Tiers, Cloud CDN, autoscaler [max instances])
• Bandwidth utilization (e.g., kernel sys tuning parameters)

Topics Assessed in Final Test

You can succeed in the actual Google Professional Cloud Network Engineer exam if you manage to demonstrate that you developed the following skills and expertise:

• Gaining knowledge of how to plan, design, and create a GCP network prototype;
• Implementing and configuring a Virtual Private Cloud using the GCP network;
• Discerning how to configure network services;
• Configuring Google Cloud features to implement network security;
• Monitoring and managing network operations;
• Ensuring network resources optimization.
• Implementing and configuring hybrid interconnectivity;

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 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.
• 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 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;
