Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q28-Q33):NEW QUESTION # 28
You need to restrict the resources available to pods deployed within a specific namespace. What Kubernetes resource should you use?
  • A. ResourceQuota
  • B. LimitRange
  • C. PodSecurityPolicy
  • D. NetworkPolicy
  • E. ServiceAccount
Answer: A
Explanation:
ResourceQuota is used to restrict the resources available to pods within a namespace. You can set limits on CPU, memory, storage, and other resources to prevent resource exhaustion. LimitRange is used to set minimum and maximum limits for resources that apply to all pods in a namespace, but not to restrict the total resources used. The other options are not relevant to resource restriction: PodSecurityPolicy restricts security settings, NetworkPolicy manages network traffic, and ServiceAccount provides identity and credentials for pods.

NEW QUESTION # 29
Scenario: You have a Kubernetes cluster hosted in a public cloud provider. When trying to create a Service of type LoadBalancer, the external-ip is stuck in the "ending" state. Which Kubernetes component is failing in this scenario?
  • A. Load Balancer Manager
  • B. Cloud Load Balancer Manager
  • C. Cloud Controller Manager
  • D. Cloud Architecture Manager
Answer: C
Explanation:
When you create a Service of type LoadBalancer in a cloud environment, Kubernetes relies on cloud-provider integration to provision an external load balancer and allocate a public IP (or equivalent). The control plane component responsible for this integration is the cloud-controller-manager, so A is correct.
In Kubernetes, a LoadBalancer Service triggers a controller loop that calls the cloud provider APIs to create/update a load balancer that forwards traffic to the cluster (often via NodePorts on worker nodes, or via provider-specific mechanisms). The Service remains with EXTERNAL-IP: Pending until the cloud provider resource is successfully created and the controller updates the Service status with the assigned external address. If that status never updates, it usually indicates the cloud integration path is broken-commonly due to: missing cloud provider configuration, broken credentials/IAM permissions, the cloud-controller-manager not running/healthy, or a misconfigured cloud provider implementation.
The other options are not real Kubernetes components. Kubernetes does not include a "Load Balancer Manager" or "Cloud Architecture Manager" component name in its standard architecture. In many managed Kubernetes offerings, the cloud-controller-manager (or its equivalent) is provided/managed by the provider, but the responsibility remains the same: reconcile Kubernetes Service resources into cloud load balancer resources.
Therefore, in this scenario, the failing component is the Cloud Controller Manager, which is the Kubernetes control plane component that interfaces with the cloud provider to provision external load balancers and update the Service status.

NEW QUESTION # 30
You are running a containerized application that requires access to a specific host-mounted directory. Which of the following is the most appropriate Kubernetes mechanism to achieve this?
  • A. VolumeMounts
  • B. Service Account
  • C. Pod Security Policy
  • D. ConfigMap
  • E. HostPort
Answer: A
Explanation:
The *VolumeMountS section within a Pod definition allows you to map host directories or persistent volumes into your container. This provides a secure and controlled way to access files from the host machine within your container. HostPort, Service Account, Pod Security Policy, and ConfigMap are all different Kubernetes concepts and do not directly address the need for host directory access.

NEW QUESTION # 31
Which persona is normally responsible for defining, testing, and running an incident management process?
  • A. Site Reliability Engineers
  • B. Application Developers
  • C. Quality Engineers
  • D. Project Managers
Answer: A
Explanation:
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.

NEW QUESTION # 32
You need to create a Kubernetes service that exposes a TCP-based application on port 8080. You want the service to be accessible from external clients. Which type of service should you create?
  • A. ClusteriP
  • B. NodePort
  • C. LoadBalancer
  • D. ExternalName
  • E. Headless
Answer: C
Explanation:
The *LoadBalancer• service type is the most suitable for exposing your TCP-based application on port 8080 to external clients. It will automatically create a load balancer in the cloud provider's infrastructure, allowing external access to your application. Option 'A' (ClusterlP) only allows access from within the cluster. Option 'C' (NodePort) exposes the service on a specific port on each node, making it accessible via the node's IP address. Option 'D' (ExternalName) is for exposing services that are already externally accessible using a DNS name. Option 'E' (Headless) is for services where you want to access Pods directly by their names, which is not the case here.
