What is the purpose of "annotationCheck" in LitmusChaos experiments?

To ensure targeted resources have chaos-specific annotations.

To validate labels on Kubernetes nodes.

To verify probe execution results.

To add custom labels to ChaosEngine.

What is the main role of chaos-operator in Litmus?

Manage ChaosEngine and experiments.

In a multi-stage Docker build, what is the primary advantage of separating build stages, and how does this impact the final container image size?

It reduces the final image size by excluding unnecessary build dependencies

It allows parallel processing of build stages

It provides better security isolation

In Kubernetes, what is the key difference between a Deployment and a ReplicaSet?

Deployments manage ReplicaSets and provide declarative updates

Deployments cannot scale, while ReplicaSets can

ReplicaSets are responsible for network routing

Deployments only work with stateless applications

When using Docker Compose, what does the depends_on directive accomplish in a multi-service configuration?

It ensures a specific startup order for services

It automatically scales services

It creates network connections between services

It defines resource limits for services

In the context of Kubernetes, what is the primary responsibility of the kube-proxy component?

Managing network connectivity and load balancing for Pods

What security best practice is demonstrated by the USER instruction in a Dockerfile?

Running containers with non-root privileges

In a Kubernetes Service of type LoadBalancer, what happens when the service is created?

It provisions an external load balancer in the cloud provider

It automatically creates a cluster-internal IP

It exposes the service on every node's IP

It creates a DNS entry for the service

What is the significance of the HEALTHCHECK instruction in a Dockerfile?

It adds a mechanism to check container health

It prevents container deployment

It increases container performance

It manages container networking

In Kubernetes, what distinguishes a ConfigMap from a Secret?

Secrets are base64 encoded and used for sensitive information

ConfigMaps can store binary data; Secrets cannot

ConfigMaps can only be used with specific types of applications

Secrets automatically rotate credentials

What is the purpose of the etcd component in the Kubernetes control plane?

Storing cluster configuration and state

In a Docker multi-stage build, what does the -from flag in the COPY instruction accomplish?

Copy files from a specific build stage

What is a key difference between virtualization and containerization?

Virtualization has lower performance overhead

Containers cannot run multiple applications

Virtualization shares the host OS kernel; containers do not

Containers run on separate operating systems

In Kubernetes, what does a Namespace primarily provide?

Logical resource partitioning and isolation

Enhanced security for applications

Network routing between clusters

What does the docker build command with the t flag do?

Tag the resulting image with a name

In Kubernetes, how does a ReplicaSet ensure the desired number of Pods are running?

By creating or deleting Pods to match the specified replica count

Through external monitoring tools

By automatically increasing resources

What is the primary purpose of the Kubernetes Scheduler?

Selecting optimal nodes for Pod placement

In a Docker Compose file, what does the volumes directive enable?

Persistent data storage and sharing between containers

What is a critical security consideration when building Docker images?

Use official base images and avoid hardcoding secrets

Always use the latest base image

In Kubernetes, what does a Pod represent?

The smallest deployable unit that can contain one or more containers

What is the function of the docker push command in a container registry workflow?

Scan an image for vulnerabilities

What is Kubescape primarily used for in a Kubernetes environment?

Security scanning and compliance checks

How does Tempo differ from Prometheus and Loki in terms of data it handles?

Tempo stores traces, while Prometheus stores metrics and Loki stores logs

Tempo stores metrics data, while Prometheus and Loki store logs

Tempo stores traces and metrics, while Loki stores logs

Tempo stores logs and traces, while Prometheus stores only metrics

In Alertmanager, what is the purpose of a silence?

To temporarily mute alerts matching specific conditions

To permanently suppress an alert

To integrate with third-party notification tools

What is the purpose of a Kubernetes ConfigMap?

Store non-sensitive configuration data in key-value pairs

Stores the replica counts of the deployments/stateful sets

Manage Pod scaling automatically

In Helm, what is the purpose of the values.yaml file?

To store default configuration values for the chart

To define the structure of a Helm chart

To manage dependencies for the chart
