Kubernetes Core Concepts and Application Architecture
Q1. A development team deploys a containerized web application to Kubernetes. The
application requires a predictable method for discovering backend services without
manually updating IP addresses whenever Pods are recreated. Which Kubernetes
resource should the developer use?
A. ConfigMap
B. Service
C. PersistentVolume
D. Namespace
Correct Answer: 🔴 B. Service
Explanation: 🔹 A Kubernetes Service provides a stable networking endpoint that
abstracts changing Pod IP addresses and enables service discovery. ConfigMaps store
configuration data, PersistentVolumes provide storage abstraction, and Namespaces
isolate resources but do not provide application connectivity.
Q2. A developer creates a Kubernetes Deployment with three replicas of an
application. After updating the container image, Kubernetes gradually replaces old
Pods with new ones while maintaining application availability. Which Deployment
capability enables this behavior?
A. Horizontal Pod Autoscaling
B. Rolling update strategy
C. Static Pod management
D. ReplicaSet deletion policy
Correct Answer: 🔴 B. Rolling update strategy
,Explanation: 🔹 Rolling updates allow Kubernetes Deployments to replace application
instances gradually, reducing downtime during updates. Horizontal Pod Autoscaling
changes replica counts, Static Pods are node-managed workloads, and ReplicaSet
deletion policies do not control progressive updates.
Q3. A developer wants to package Kubernetes application manifests, templates, and
configurable values into a reusable deployment unit. Which tool is most appropriate?
A. Docker Compose
B. Helm
C. kubelet
D. containerd
Correct Answer: 🔴 B. Helm
Explanation: 🔹 Helm is the Kubernetes package manager that uses charts containing
templates and configurable values. Docker Compose is designed for local multi-
container applications, kubelet manages Pods on nodes, and containerd runs
containers but does not package Kubernetes applications.
Q4. An application requires environment-specific configuration values such as
database URLs and feature flags without rebuilding container images. Which
Kubernetes object should store these values?
A. ConfigMap
B. PodSecurityPolicy
C. Node
D. ReplicaSet
Correct Answer: 🔴 A. ConfigMap
Explanation: 🔹 ConfigMaps separate application configuration from container images,
allowing the same image to run in multiple environments. PodSecurityPolicy relates to
, security controls, Nodes provide compute resources, and ReplicaSets maintain Pod
counts.
Q5. A Kubernetes developer needs to ensure that a container receives sensitive
credentials such as database passwords securely. Which object should be used?
A. Secret
B. Namespace
C. ServiceAccount
D. Deployment
Correct Answer: 🔴 A. Secret
Explanation: 🔹 Kubernetes Secrets are designed for storing sensitive information such
as credentials and tokens. Namespaces organize resources, ServiceAccounts provide
identities, and Deployments manage application replicas.
Pods, Containers, and Workload Management
Q6. A Pod contains two containers. One container provides an application API, while
the second container collects logs from the first container. What Kubernetes pattern
is being implemented?
A. Blue-green deployment
B. Sidecar pattern
C. Stateful workload pattern
D. DaemonSet pattern
Correct Answer: 🔴 B. Sidecar pattern
Explanation: 🔹 The sidecar pattern uses an additional container within the same Pod
to extend or support the primary application container. Blue-green deployments
manage releases, Stateful workloads manage persistent identities, and DaemonSets run
Pods on nodes.
