Demo Questions

You are designing a Google Kubernetes Engine (GKE) cluster for your organization. The current cluster size is expected to host 10 nodes, with 20 Pods per node and 150 services. Because of the migration of new services over the next 2 years, there is a planned growth for 100 nodes, 200 Pods per node, and 1500 services. You want to use VPC-native clusters with alias IP ranges, while minimizing address consumption.

How should you design this topology?

Create a subnet of size/25 with 2 secondary ranges of: /17 for Pods and /21 for Services. Create a VPC-native cluster and specify those ranges.
Create a subnet of size/28 with 2 secondary ranges of: /24 for Pods and /24 for Services. Create a VPC-native cluster and specify those ranges. When the services are ready to be deployed, resize the subnets.
Use gcloud container clusters create [CLUSTER NAME]--enable-ip-alias to create a VPC-native cluster.
Use gcloud container clusters create [CLUSTER NAME] to create a VPC-native cluster.

Correct answer: A

Explanation:

The service range setting is permanent and cannot be changed. Please seehttps://stackoverflow.com/questions/60957040/how-to-increase-the-service-address-range-of-agke-clusterI think the correc tanswer is A since: Grow is expected to up to 100 nodes (that would be/25), then up to 200 pods per node (100 times 200 = 20000 so /17 is 32768), then 1500 services in a/21 (up to 2048)https://docs.netgate.com/pfsense/en/latest/book/network/understanding-cidr-subnet-masknotation.html

Your company's web server administrator is migrating on-premises backend servers for an application to GCP. Libraries and configurations differ significantly across these backend servers. The migration to GCP will be lift-andshift, and all requests to the servers will be served by a single network load balancer frontend. You want to use a GCP-native solution when possible.

How should you deploy this service in GCP?

Create a managed instance group from one of the images of the on-premises servers, and link this instance group to a target pool behind your load balancer.
Create a target pool, add all backend instances to this target pool, and deploy the target pool behind your load balancer.
Deploy a third-party virtual appliance as frontend to these servers that will accommodate the significant differences between these backend servers.
Use GCP's ECMP capability to load-balance traffic to the backend servers by installing multiple equal-priority static routes to the backend servers.

Correct answer: B

You decide to set up Cloud NAT. After completing the configuration, you find that one of your instances is not using the Cloud NAT for outbound NAT.

What is the most likely cause of this problem?
