Objective 1.4

PCNE

Designing for Google Kubernetes Engine (GKE)

Objective 1.4 sits in Designing and planning a Google Cloud VPC network, which carries 21% of the Cloud Network Engineer exam. The questions below are original, written from the official objective title above, and each explanation cites the Google Cloud page it rests on.

A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-4Designing and planning a Google Cloud VPC network

An engineer compares the two GKE cluster network modes and needs Pod traffic to stay clear of the custom static route quota. Which routing arrangement achieves that?

Per-node routes advertised by a Cloud RouterDynamic advertisement is a hybrid concern, not a Pod one.
Custom static routes generated for each nodeThat is the routes-based mode this design avoids.
A route-based overlay tunnelled between nodesNo tunnel is built between nodes in either mode.
Alias IP ranges served by automatic subnet routesCorrect · your answerCorrect. Nothing per node is added to the routing table.

Correct.

Concept

How a platform reaches a workload address decides which quota the design consumes, so two schemes carrying the same traffic can have very different scaling ceilings.

Why D

In a VPC-native cluster the Pod IP address ranges do not depend on custom static routes and do not consume the static route quota; automatically generated subnet routes carry that traffic instead.

Source

Pod IP address ranges don't depend on custom static routes. They don't consume the system-generated and custom static routes quota . Instead, automatically-generated subnet routes handle routing for VPC-native clusters.

Now you: objective 1.4 questions

No account needed. The explanation opens when you answer.

Sample question 1 of 3

1-4Designing and planning a Google Cloud VPC network

A team leaves the maximum Pods per node at its default on a VPC-native cluster. How large an alias IP range does each node receive?

Sample question 2 of 3

1-4Designing and planning a Google Cloud VPC network

A team plans a 900-node VPC-native cluster and has to size the cluster subnet properly. Which range supplies the addresses for the nodes themselves?

Sample question 3 of 3

1-4Designing and planning a Google Cloud VPC network

An engineer sizes the Pod secondary range for a 900-node VPC-native cluster running the default 110 Pods per node. What is the largest subnet mask that will fit?
