최신 Kubernetes Cloud Native Associate KCNA 무료샘플문제 (Q279-Q284):

질문 # 279
During a team meeting, a developer mentions the significance of open collaboration in the cloud native ecosystem. Which statement accurately reflects principles of collaborative development and community stewardship?

A. Community events and working groups foster collaboration by bringing people together to share knowledge and build connections.
B. Open source projects succeed when contributors focus on code quality without the overhead of community engagement.
C. Maintainers of open source projects act independently to make technical decisions without requiring input from contributors.
D. Community stewardship emphasizes guiding project growth but does not necessarily include sustainability considerations.

정답：A

설명：
Collaborative development in the cloud native ecosystem is built on open collaboration, where community events and working groups enable knowledge sharing, collective problem solving, and relationship building, all of which are essential for healthy, sustainable open source projects.

질문 # 280
Which of the following is a recommended security habit in Kubernetes?

A. Run the containers as the user with user ID 0 (root) and any group ID.
B. Run the containers as the user with group ID 0 (root) and any user ID.
C. Allow privilege escalation from within a container as the default option.
D. Disallow privilege escalation from within a container as the default option.

정답：D

설명：
Disallowing privilege escalation within containers by default helps reduce the attack surface and enhances Kubernetes security best practices.

질문 # 281
Which of the following is a good habit for cloud native cost efficiency?

A. Follow manual processes for cost analysis, including visibility and forecasting.
B. Keep your legacy workloads unchanged, to avoid cloud costs.
C. Follow an automated approach to cost optimization, including visibility and forecasting.
D. Use only one cloud provider to simplify the cost analysis.

정답：C

설명：
The correct answer is A. In cloud-native environments, costs are highly dynamic: autoscaling changes compute footprint, ephemeral environments come and go, and usage-based billing applies to storage, network egress, load balancers, and observability tooling. Because of this variability, automation is the most sustainable way to achieve cost efficiency. Automated visibility (dashboards, chargeback/showback), anomaly detection, and forecasting help teams understand where spend is coming from and how it changes over time. Automated optimization actions can include right-sizing requests/limits, enforcing TTLs on preview environments, scaling down idle clusters, and cleaning unused resources.
Manual processes (B) don't scale as complexity grows. By the time someone reviews a spreadsheet or dashboard weekly, cost spikes may have already occurred. Automation enables fast feedback loops and guardrails, which is essential for preventing runaway spend caused by misconfiguration (e.g., excessive log ingestion, unbounded autoscaling, oversized node pools).
Option C is not a cost-efficiency "habit." Single-provider strategies may simplify some billing views, but they can also reduce leverage and may not be feasible for resilience/compliance; it's a business choice, not a best practice for cloud-native cost management. Option D is counterproductive: keeping legacy workloads unchanged often wastes money because cloud efficiency typically requires adapting workloads-right-sizing, adopting autoscaling, and using managed services appropriately.
In Kubernetes specifically, cost efficiency is tightly linked to resource management: accurate CPU/memory requests, limits where appropriate, cluster autoscaler tuning, and avoiding overprovisioning. Observability also matters because you can't optimize what you can't measure. Therefore, the best habit is an automated cost optimization approach with strong visibility and forecasting-A.

질문 # 282
What components are common in a service mesh?

A. Tracing and log storage
B. Circuit breaking and Pod scheduling
C. Service proxy and control plane
D. Data plane and runtime plane

정답：C

설명：
A service mesh is an architectural pattern that manages service-to-service communication in a microservices environment by inserting a dedicated networking layer. The two most common building blocks you'll see across service mesh implementations are (1) a data plane of proxies and (2) a control plane that configures and manages those proxies-this aligns best with "service proxy and control plane," option D.
In practice, the data plane is usually implemented via sidecar proxies (or sometimes node/ambient proxies) that sit "next to" workloads and handle traffic functions such as mTLS encryption, retries, timeouts, load balancing policies, traffic splitting, and telemetry generation. These proxies can capture inbound and outbound traffic without requiring changes to application code, which is one of the defining benefits of a mesh.
The control plane provides the management layer: it distributes policy and configuration to the proxies (routing rules, security policies, identities/certificates), discovers services/endpoints, and often coordinates certificate rotation and workload identity. In Kubernetes environments, meshes typically integrate with the Kubernetes API for service discovery and configuration.
Option C is close in spirit but uses non-standard wording ("runtime plane" is not a typical service mesh term;
"control plane" is). Options A and B describe capabilities that may exist in a mesh ecosystem (telemetry, circuit breaking), but they are not the universal "core components" across meshes. Tracing/log storage, for example, is usually handled by external observability backends (e.g., Jaeger, Tempo, Loki) rather than being intrinsic "mesh components." So, the most correct and broadly accepted answer is D: service proxy and control plane.

질문 # 283
What can be used to create a job that will run at specified times/dates or on a repeating schedule?

A. BatchJob
B. CalenderJob
C. Job
D. CronJob

정답：D

설명：
A CronJob in Kubernetes is designed to run jobs on a specified schedule, similar to the Unix cron utility, allowing execution at defined times or intervals.
