Linux Foundation Certified Cloud Native Platform Engineering Associate Sample Questions (Q43-Q48):NEW QUESTION # 43
Which of the following best describes the primary function of an incident management system during a platform outage?
  • A. Automatically generate detailed incident documentation, including the timeline and actions taken by the response team.
  • B. Retroactively analyze system logs and metrics after the incident resolution to identify the root cause.
  • C. Centralize alerts, facilitate notification to the appropriate on-call personnel, coordinate communication, and provide visibility into the incident status.
  • D. Automatically execute predefined remediation scripts on the affected systems to resolve the incident without human intervention.
Answer: C
Explanation:
An incident management system's primary function is to coordinate response during outages, ensuring that alerts are centralized, on-call personnel are notified, communication is managed, and visibility is maintained.
Option B is correct because it emphasizes the core responsibilities of incident management systems like PagerDuty, Opsgenie, or ServiceNow. These systems streamline response efforts, reducing mean time to recovery (MTTR).
Option A (incident documentation) is valuable but usually a secondary outcome of incident management.
Option C (root cause analysis) is part of post-incident reviews, not the primary function during active response. Option D (automated remediation) may be supported by runbooks but is not the core role of incident management systems.
By centralizing and standardizing incident response, these systems enhance collaboration, reduce confusion, and provide stakeholders with up-to-date information on incident status, which is critical for maintaining trust and operational resilience.

NEW QUESTION # 44
A platform engineering team needs to provide comprehensive cost visibility for Kubernetes workloads to optimize infrastructure utilization. Which tool is recommended to achieve this goal?
  • A. Kubernetes resource usage metrics paired with cloud provider billing data.
  • B. OpenCost for real-time, granular Kubernetes cost allocation and analysis.
  • C. Application performance monitoring tools with limited resource cost tracking.
  • D. Cloud provider cost estimation tools with basic Kubernetes integration.
Answer: B
Explanation:
OpenCost is the CNCF-supported open-source project designed specifically for Kubernetes cost visibility and optimization. Option B is correct because OpenCost provides granular, real-time allocation of Kubernetes costs across namespaces, workloads, and teams. This allows organizations to understand true cost drivers and optimize resource utilization effectively.
Option A (APM tools) may track performance but usually lack deep integration with Kubernetes cost allocation. Option C provides partial visibility but requires complex manual correlation of resource usage with billing data. Option D (cloud provider estimators) typically offer limited or high-level insights and do not map costs down to Kubernetes workloads.
By adopting OpenCost, platform teams can align financial accountability with engineering usage, a practice known as FinOps. This supports sustainable scaling, cost efficiency, and transparency-critical aspects of measuring platform success.

NEW QUESTION # 45
Which Kubernetes feature allows you to control how Pods communicate with each other and external services?
  • A. Role-based access control (RBAC)
  • B. Security Context
  • C. Pod Security Standards
  • D. Network Policies
Answer: D
Explanation:
Kubernetes Network Policies are the feature that controls how Pods communicate with each other and external services. Option B is correct because Network Policies define rules for ingress (incoming) and egress (outgoing) traffic at the Pod level, ensuring fine-grained control over communication pathways within the cluster.
Option A (Pod Security Standards) defines policies around Pod security contexts (e.g., privilege escalation, root access) but does not control network traffic. Option C (Security Context) is specific to Pod or container- level permissions, not networking. Option D (RBAC) governs access to Kubernetes API resources, not Pod-to- Pod traffic.
Network Policies are essential for implementing a zero-trust model in Kubernetes, ensuring that only authorized services communicate. This enhances both security and compliance, especially in multi-tenant clusters.

NEW QUESTION # 46
If you update a Deployment's replica count from 3 to 5, how does the reconciliation loop respond?
  • A. It will wait for an admin to manually add two more Pod definitions.
  • B. It will restart the existing Pods before adding any new Pods.
  • C. It will delete the Deployment and require you to re-create it with 5 replicas.
  • D. It will create new Pods to meet the new replica count of 5.
Answer: D
Explanation:
The Kubernetes reconciliation loop ensures that the actual state of a resource matches the desired state defined in its manifest. If the replica count of a Deployment is changed from 3 to 5, option B is correct:
Kubernetes will automatically create two new Pods to satisfy the new desired replica count.
Option A is incorrect because Deployments are not deleted; they are updated in place. Option C contradicts Kubernetes' declarative model-no manual intervention is required. Option D is wrong because Kubernetes does not restart existing Pods unless necessary; it simply adds additional Pods.
This reconciliation process is core to Kubernetes' declarative infrastructure approach, where desired states are continuously monitored and enforced. It reduces human toil and ensures consistency, making it fundamental for platform engineering practices like GitOps.

NEW QUESTION # 47
What is a key consideration during the setup of a Continuous Integration/Continuous Deployment (CI/CD) pipeline to ensure efficient and reliable software delivery?
  • A. Skip the packaging step to save time and reduce complexity.
  • B. Implement automated testing at multiple points in the pipeline.
  • C. Using a single development environment for all stages of the pipeline.
  • D. Manually approve each build before deployment to maintain control over quality.
Answer: B
Explanation:
Automated testing throughout the pipeline is a key enabler of efficient and reliable delivery. Option B is correct because incorporating unit tests, integration tests, and security scans at different pipeline stages ensures that errors are caught early, reducing the risk of faulty code reaching production. This also accelerates delivery by providing fast, consistent feedback to developers.
Option A (single environment) undermines isolation and does not reflect real-world deployment conditions.
Option C (skipping packaging) prevents reproducibility and traceability of builds. Option D (manual approvals) adds delays and reintroduces human bottlenecks, which goes against DevOps and GitOps automation principles.
Automated testing, combined with immutable artifacts and GitOps-driven deployments, aligns with platform engineering's focus on automation, reliability, and developer experience. It reduces cognitive load for teams and enforces quality consistently.
