• Standalone or shared
• Multiple vs. single
• Differences between Google Cloud Networking and other cloud platforms
• IP addressing (e.g., static, ephemeral, private)
• CIDR range for subnets
• Routes

Designing a hybrid network. Considerations include:

• Cloud Router

• Using interconnect (e.g., dedicated vs. partner)
• Peering options (e.g., direct vs. carrier)
• Shared vs. standalone VPC interconnect access
• Failover and disaster recovery strategy (e.g., building high availability with BGP using cloud router)
• IPsec VPN
• Cross-organizational access

Designing a container IP addressing plan for Google Kubernetes Engine

2. Implementing a GCP Virtual Private Cloud (VPC)

Configuring VPCs. Considerations include:

• Configuring VPC flow logs
• Configuring GCP VPC resources (CIDR range, subnets, firewall rules, etc.)
• Configuring VPC peering
• Creating a shared VPC and explaining how to share subnets with other projects
• Configuring API access (private, public, NAT GW, proxy)

Configuring routing. Tasks include:

• Configuring internal static/dynamic routing
• Configuring routing policies using tags and priority
• Configuring NAT (e.g., Cloud NAT, instance-based NAT)

Configuring and maintaining Google Kubernetes Engine clusters. Considerations include:

• Clusters with shared VPC
• Private clusters
• Cluster network policy
• Adding authorized networks for cluster master access
• VPC-native clusters using alias IPs

Configuring and managing firewall rules. Considerations include:

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

3. Configuring network services

Configuring load balancing. Considerations include:

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

Configuring Cloud CDN. Considerations include:

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

Configuring and maintaining Cloud DNS. Considerations include:

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

Enabling other network services. Considerations include:

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

4. Implementing hybrid interconnectivity

Configuring interconnect. Considerations include:

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

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:

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

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:

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

Maintaining and troubleshooting connectivity issues. Considerations include:

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

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:

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

Optimizing for cost and efficiency. Considerations include:

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

Implement Hybrid Interconnectivity

• Configure Interconnect: This part measures one’s understanding of partner (that is layer 2 versus layer 3 connectivity), bulk storage uploads, and virtualizing with the use of VLAN attachments;
• Configure Cloud Router for Dependability: You will also be expected to demonstrate competence in this domain as well as in the configuration of site-to-site IPsec VPN.

The Google Professional Cloud Network Engineer exam helps the specialists use the Google Cloud Platform for managing and implementing network architectures.
