3. Configuring network services

Configuring load balancing. Considerations include:

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

Configuring Cloud CDN. Considerations include:

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

Configuring and maintaining Cloud DNS. Considerations include:

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

Enabling other network services. Considerations include:

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

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:

• Defining custom IAM roles
• Viewing account IAM assignments
• Using pre-defined IAM roles (e.g., network admin, network viewer, network user)
• 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:

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

Maintaining and troubleshooting connectivity issues. Considerations include:

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

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)
• Global vs. regional dynamic routing
• Expanding subnet CIDR ranges in service
• Load balancer and CDN location

Optimizing for cost and efficiency. Considerations include:

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

Manage & Monitor Network Operations

In this part of the exam content, the students should be able to log and monitor with the use of GCP Console or Stackdriver. They must have competence in the management and maintenance of security, which includes firewalls and diagnosing & resolving IAM problems. Besides that, they need to be able to deal with the following objective:

• Maintain & Troubleshoot Connectivity Issues: It includes the identification of traffic flow topology, redirecting and draining of traffic flows, and cross-connect hand-off for interconnect. It also measures one’s knowledge of the monitoring of egress and ingress traffic with the use of flow logs as well as monitoring firewall logs. This section will also evaluate the learners’ skills in troubleshooting and managing VPNs and troubleshooting peering issues with Cloud Router BGP.

The applicants should also demonstrate competence in troubleshooting, monitoring, and maintaining traffic flow and latency, which include routing issues, network latency testing & throughput, and tracing traffic flow.
