QUESTION 134
What native runtime is Open Container Initiative (OCI) compliant?

runC

runV

kata-containers

gvisor

QUESTION 135
What is the name of the Kubernetes agent that runs on each worker nodes?

kubelet

systemd

kube-proxy

pod

QUESTION 136
What is Flux constructed with?

GitLab Environment Toolkit

GitOps Toolkit

Helm Toolkit

GitHub Actions Toolkit

QUESTION 137
You are developing a microservices application where each service requires a specific configuration. Which Kubernetes feature best addresses this need for service-specific configuration?

ConfigMaps

Secrets

Persistent Volumes

Deployments

Namespaces

QUESTION 138
Consider a pod with a “readinessProbe” that checks for a specific file existence. Explain what happens if the probe fails repeatedly, and how it affects the pod’s lifecycle.

The pod will be automatically restarted.

The pod will be marked as “unhealthy”, but will continue to run.

The pod will be terminated and removed from the cluster.

The pod will be rescheduled to a different node in the cluster.

The pod will be automatically scaled down.

QUESTION 139
You are running a service in Kubernetes that uses a persistent volume. You need to ensure that the volume is automatically cleaned up when the service is deleted. Which of the following approaches would you use?

Set the ‘persistentVolumeReclaimPolicy’ to ‘Delete’ in the PersistentVolumeClaim

Delete the PersistentVolumeClaim manually when the service is deleted

Use a DaemonSet to run a cleanup script that removes the volume when the service is deleted

Configure a CronJob to periodically check for unused volumes and delete them

There is no automatic way to clean up a persistent volume when a service is deleted; it needs to be done manually.

QUESTION 140
Which component of the node is responsible to run workloads?

The kubelet.

The kube-proxy.

The kube-apiserver.

The container runtime.

QUESTION 141
You are using Prometheus to monitor your Kubernetes cluster. You notice that several pods are
experiencing high memory usage. You want to investigate further to determine which containers within these pods are consuming the most memory. How can you effectively use Prometheus to identify these memory-intensive containers?

Use the metric to identify the requested memory limits for each containa

Use the ‘kube_pod_container_status_memory_usage_bytes’ metric to analyze the actual memory usage of each container.

Utilize the • metric to identify containers that are frequently restarting due to memory pressure.

Filter Prometheus queries by container name and sort by memory usage to pinpoint the memory-intensive containers.

Utilize the metric to identify pods that are not ready due to memory constraints.

QUESTION 142
You have configured Prometheus to scrape metrics from a Kubernetes cluster, but you notice that some pods are not being scraped. You suspect that the Prometheus server might be experiencing resource constraints. How can you troubleshoot this issue?

Check the Prometheus logs for any errors related to scraping or resource limitations.

Examine the Prometheus server’s CPU and memory usage to identify any resource bottlenecks.

Verify the Prometheus server’s configuration and ensure that the scraping interval and target labels are correct.

Use the Prometheus •status/targets• endpoint to see which targets are currently being scraped and any errors encountered.

All of the above

QUESTION 143
Which of the following sentences is true about container runtimes in Kubernetes?

If you let iptables see bridged traffic, you don’t need a container runtime.

If you enable IPv4 forwarding, you don’t need a container runtime.

Container runtimes are deprecated, you must install CRI on each node.

You must install a container runtime on each node to run pods on it.

QUESTION 144
You’re designing a serverless application that processes large amounts of data using AWS Lambd
a. You need to ensure that your Lambda functions can handle potential spikes in workload without compromising performance. Which of the following approaches would be most effective in achieving this goal?

Configure Lambda functions to use a larger memory allocation.

Implement a message queue in front of Lambda functions to buffer incoming requests.

Utilize AWS Elastic Beanstalk to auto-scale Lambda functions based on workload.

Use serverless frameworks like AWS Serverless Application Model (SAM) to manage Lambda deployments.

Enable concurrency settings for Lambda functions to allow multiple invocations simultaneously.

QUESTION 145
Which persona is normally responsible for defining, testing, and running an incident management process?

Site Reliability Engineers

Project Managers

Application Developers

Quality Engineers

The role most commonly responsible for defining, testing, and running an incident management process is Site Reliability Engineers (SREs), so A is correct. SRE is an operational engineering discipline focused on ensuring reliability, availability, and performance of services in production. Incident management is a core part of that mission: when outages or severe degradations occur, someone must coordinate response, restore service quickly, and then drive follow-up improvements to prevent recurrence.
In cloud native environments (including Kubernetes), incident response involves both technical and process elements. On the technical side, SREs ensure observability is in place-metrics, logs, traces, dashboards, and actionable alerts-so incidents can be detected and diagnosed quickly. They also validate operational readiness: runbooks, escalation paths, on-call rotations, and post-incident review practices. On the process side, SREs often establish severity classifications, response roles (incident commander, communications lead, subject matter experts), and “game day” exercises or simulated incidents to test preparedness.
Project managers may help coordinate schedules and communication for projects, but they are not typically the owners of operational incident response mechanics. Application developers are crucial participants during incidents, especially for debugging application-level failures, but they are not usually the primary maintainers of the incident management framework. Quality engineers focus on testing and quality assurance, and while they contribute to preventing defects, they are not usually the owners of real-time incident operations.
In Kubernetes specifically, incidents often span multiple layers: workload behavior, cluster resources, networking, storage, and platform dependencies. SREs are positioned to manage the cross-cutting operational view and to continuously improve reliability through error budgets, SLOs/SLIs, and iterative hardening. That’ s why the correct persona is Site Reliability Engineers.
