Linux Foundation Certified Cloud Native Platform Engineering Associate CNPA Prüfungsfragen mit Lösungen (Q74-Q79):

74. Frage
Which of the following is a primary benefit of adopting a platform approach for managing application environments with diverse needs?

A. It enforces one infrastructure setup for all applications to reduce management complexity.
B. It enables self-service infrastructure provisioning while supporting app-specific requirements and organizational standards.
C. It centralizes all deployments in one environment to improve control and visibility.
D. It isolates application environments completely to maximize security and avoid shared resources.

Antwort: B

Begründung:
The main advantage of a platform engineering approach is balancing self-service for developers with organizational governance and standardization. Option A is correct because platforms enable developers to provision infrastructure and application environments independently while embedding security, compliance, and operational guardrails. This ensures that applications with diverse needs (e.g., different scaling patterns, compliance requirements, or environments) can still operate within a unified governance framework.
Option B (isolation only) is sometimes required for compliance but does not address the broader benefit of balancing flexibility and standardization. Option C forces uniformity, which reduces adaptability for varied workloads. Option D (centralized deployments) reduces developer autonomy and scalability.
The platform approach enables golden paths, curated abstractions, and reusable services, allowing diverse applications to thrive while maintaining control. This balance is central to platform engineering's goal of reducing cognitive load and improving developer productivity.

75. Frage
In a scenario where an Internal Developer Platform (IDP) is being used to enable developers to self-service provision products and capabilities such as Namespace-as-a-Service, which answer best describes who is responsible for resolving application-related incidents?

A. Platform teams are responsible for investigating and resolving all problems related to the platform, including application ones, before the app teams notice.
B. Platform teams delegate appropriate permissions to the application teams to allow them to self-manage and resolve any underlying infrastructure and application-related problems.
C. A separate team is created which includes people previously from the platform and application teams to solve all problems for the organization.
D. Platform teams are responsible for investigating and resolving underlying infrastructure problems whilst application teams are responsible for investigating and resolving application-related problems.

Antwort: D

Begründung:
Platform engineering clearly separates responsibilities between platform teams and application teams. Option C is correct because platform teams manage the platform and infrastructure layer, ensuring stability, compliance, and availability, while application teams own their applications, including troubleshooting application-specific issues.
Option A (creating a single merged team) introduces inefficiency and removes specialization. Option B incorrectly suggests application teams should also solve infrastructure issues, which conflicts with platform- as-a-product principles. Option D places all responsibilities on platform teams, which creates bottlenecks and undermines application team ownership.
By splitting responsibilities, IDPs empower developers with self-service provisioning while maintaining clear boundaries. This ensures both agility and accountability: platform teams focus on enabling and securing the platform, while application teams take ownership of their code and services.

76. Frage
In a cloud native environment, what is one of the security benefits of implementing a service mesh?

A. Limiting network access to services based on IP allowlisting.
B. Enabling encryption of communication between services using mTLS.
C. Using a centralized logging system to monitor service interactions.
D. Automatically scaling services to handle increased traffic.

Antwort: B

Begründung:
A key advantage of using a service mesh is its ability to secure service-to-service communication transparently, without requiring application code changes. Option A is correct because service meshes (e.g., Istio, Linkerd) provide mutual TLS (mTLS) by default, ensuring both encryption in transit and authentication between services. This establishes a zero-trust networking model inside the cluster.
Option B (scaling) is managed by Kubernetes (Horizontal Pod Autoscaler), not service mesh. Option C (logging) may be supported as an observability feature, but it is not the primary security benefit. Option D (IP allowlisting) is an outdated, less flexible mechanism compared to identity-based policies that meshes provide.
Service meshes enforce security consistently across all services, support fine-grained policies, and ensure compliance without burdening developers with complex configurations. This makes mTLS a foundational benefit in cloud native platform security.

77. Frage
A developer is tasked with securing a Kubernetes cluster and needs to implement Role-Based Access Control (RBAC) to manage user permissions. Which of the following statements about RBAC in Kubernetes is correct?

A. RBAC uses roles and role bindings to grant permissions to users for specific resources and actions.
B. RBAC allows users to have unrestricted roles and access to all resources in the cluster.
C. RBAC does not support namespace isolation and applies globally across the cluster.
D. RBAC is only applicable to Pods and does not extend to other Kubernetes resources.

Antwort: A

Begründung:
Role-Based Access Control (RBAC) in Kubernetes is a cornerstone of cluster security, enabling fine-grained access control based on the principle of least privilege. Option D is correct because RBAC leverages Roles (or ClusterRoles) that define sets of permissions, and RoleBindings (or ClusterRoleBindings) that assign those roles to users, groups, or service accounts. This mechanism ensures that users have only the minimum required access to perform their tasks, enhancing both security and governance.
Option A is incorrect because RBAC fully supports namespace-scoped roles, allowing isolation of permissions at the namespace level in addition to cluster-wide roles. Option B is wrong because RBAC is specifically designed to restrict, not grant, unrestricted access. Option C is misleading because RBAC applies broadly across Kubernetes API resources, not just Pods-it includes ConfigMaps, Secrets, Deployments, Services, and more.
By applying RBAC correctly, platform teams can align with security best practices, ensuring that sensitive operations (e.g., managing secrets or modifying cluster configurations) are tightly controlled. RBAC is also central to compliance frameworks, as it provides auditability of who has access to what resources.

78. Frage
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. Using a single development environment for all stages of the pipeline.
B. Skip the packaging step to save time and reduce complexity.
C. Implement automated testing at multiple points in the pipeline.
D. Manually approve each build before deployment to maintain control over quality.

Antwort: C

Begründung:
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.
