Q1. Which Kubernetes control plane component is responsible for watching for newly created Pods with no assigned node and selecting a node for them to run on?

A. kube-apiserver
B. etcd
C. kube-scheduler
D. kube-controller-manager

Show answer & explanation

✓ Answer: C. kube-scheduler

Q2. In a Deployment's rolling update strategy, what does the `maxSurge` parameter control?

A. The maximum number of Pods that can be unavailable during the update.
B. The maximum number of new Pods that can be created above the desired number of replicas.
C. The total number of Pods allowed in the cluster during the update.
D. The maximum number of old Pods that must be terminated before creating new ones.

Show answer & explanation

✓ Answer: B. The maximum number of new Pods that can be created above the desired number of replicas.

`maxSurge` specifies the maximum number of Pods that can be created over the desired `replicas` count, allowing for a smoother rollout without reducing capacity.

Q3. Which kube-proxy mode is generally considered the most performant for clusters with a very large number of Services, as it uses in-kernel hash tables for routing?

B. iptables
C. ipvs
D. kernelspace

✓ Answer: C. ipvs

The IPVS (IP Virtual Server) mode leverages the Linux kernel's Layer 4 load balancing, which is more efficient and scalable than using iptables rules.
