Topic 1 Question 116
You need to configure a Google Kubernetes Engine (GKE) cluster. The initial deployment should have 5 nodes with the potential to scale to 10 nodes. The maximum number of Pods per node is 8. The number of services could grow from 100 to up to 1024. How should you design the IP schema to optimally meet this requirement?
- Configure a /28 primary IP address range for the node IP addresses. Configure a /25 secondary IP range for the Pods. Configure a /22 secondary IP range for the Services.
- Configure a /28 primary IP address range for the node IP addresses. Configure a /25 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.
- Configure a /28 primary IP address range for the node IP addresses. Configure a /28 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.
- Configure a /28 primary IP address range for the node IP addresses. Configure a /24 secondary IP range for the Pads. Configure a /22 secondary IP range for the Services.

- /22 has only 1022 usable IP addresses, looks like B is the correct answer.

  10 nodes = /28 can max 12 nodes 8 Pods per node = 80 Pods = /24 max 110 Pods 1024 services = /22 max 1024 services

- B. Configure a /28 primary IP address range for the node IP addresses. Configure a /25 secondary IP range for the Pods. Configure a /21 secondary IP range for the Services.
  
  B is perfect answer 10 nodes /28 ( 16-2 =14 hosts) 80 pods /25 (128-2=126 hosts) 1024 /21 2048 2046
