  • Troubleshooting Cloud Router BGP peering issues

Monitoring, maintaining, and troubleshooting latency and traffic flow. Considerations include: Network throughput and latency testingRouting issuesTracing traffic flow 7. Optimizing network resources Optimizing traffic flow. Considerations include:

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

Optimizing for cost and efficiency. Considerations include:

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

Google Cloud Certified - Professional Cloud Network Engineer Sample Questions (Q38-Q43):

NEW QUESTION # 38
You want to apply a new Cloud Armor policy to an application that is deployed in Google Kubernetes Engine (GKE). You want to find out which target to use for your Cloud Armor policy.
Which GKE resource should you use?

  • A. GKE Cluster
  • B. GKE Node
  • C. GKE Ingress
  • D. GKE Pod

Answer: C Explanation:
Cloud Armour is applied at load balancers Configuring Google Cloud Armor through Ingress. https://cloud.google.com/kubernetes-engine/docs/how-to/ingress-features Security policy features Google Cloud Armor security policies have the following core features: You can optionally use the QUIC protocol with load balancers that use Google Cloud Armor. You can use Google Cloud Armor with external HTTP(S) load balancers that are in either Premium Tier or Standard Tier. You can use security policies with GKE and the default Ingress controller.
