質問 # 60
Which command will list the resource types that exist within a cluster?
正解：C
解説：
To list the resource types available in a Kubernetes cluster, you use kubectl api-resources, so A is correct. This command queries the API server's discovery endpoints and prints a table of resources (kinds) that the cluster knows about, including their names, shortnames, API group/version, whether they are namespaced, and supported verbs. It's extremely useful for learning what objects exist in a cluster-especially when CRDs are installed, because those custom resource types will also appear in the output.
Option C (kubectl api-versions) lists available API versions (group/version strings like v1, apps/v1, batch/v1) but does not directly list the resource kinds/types. It's related discovery information but answers a different question. Option B (kubectl get namespaces) lists namespaces, not resource types. Option D is invalid (typo in URL and conceptually not the Kubernetes discovery mechanism).
Practically, kubectl api-resources is used during troubleshooting and exploration: you might use it to confirm whether a CRD is installed (e.g., certificates.cert-manager.io kinds), to check whether a resource is namespaced, or to find the correct kind name for kubectl get. It also helps understand what your cluster supports at the API layer (including aggregated APIs).
So, the verified correct command to list resource types that exist in the cluster is A: kubectl api-resources.
質問 # 61
Which of the following is a challenge derived from running cloud native applications?
正解：C
解説：
The correct answer is B. Cloud-native applications often run across multiple environments-different cloud providers, regions, accounts/projects, and sometimes hybrid deployments. This introduces real cost-management complexity: pricing models differ (compute types, storage tiers, network egress), discount mechanisms vary (reserved capacity, savings plans), and telemetry/charge attribution can be inconsistent. When you add Kubernetes, the abstraction layer can further obscure cost drivers because costs are incurred at the infrastructure level (nodes, disks, load balancers) while consumption happens at the workload level (namespaces, Pods, services).
Option A is less relevant because cloud-native adoption often reduces dependence on maintaining a private datacenter; many organizations adopt cloud-native specifically to avoid datacenter CapEx/ops overhead. Option C is generally untrue-public registries and vendor registries contain vast numbers of images; the challenge is more about provenance, security, and supply chain than "lack of images." Option D is incorrect because major clouds offer abundant services; the difficulty is choosing among them and controlling cost/complexity, not a lack of services.
Cost optimization being complex is a recognized challenge because cloud-native architectures include microservices sprawl, autoscaling, ephemeral environments, and pay-per-use dependencies (managed databases, message queues, observability). Small misconfigurations can cause big bills: noisy logs, over-requested resources, unbounded HPA scaling, and egress-heavy architectures. That's why practices like FinOps, tagging/labeling for allocation, and automated guardrails are emphasized.
So the best answer describing a real, common cloud-native challenge is B.
質問 # 62
Which Kubernetes-native deployment strategy supports zero-downtime updates of a workload?
正解：A
解説：
The RollingUpdate deployment strategy updates pods incrementally, allowing zero-downtime updates by gradually replacing old pods with new ones.
質問 # 63
Your Kubernetes cluster is running a batch processing workload that only needs to run during specific time windows. How can you effectively manage the cost associated with this workload?
正解：B、C
解説：
For batch processing workloads with defined time windows, scheduling and leveraging cost- effective resources are key. CronJobs can be used to schedule the workload to run only during the required time window, eliminating unnecessary resource consumption. Utilizing spot instances or preemptible nodes provides discounted pricing for workloads that can tolerate interruptions, further reducing costs. While HPA can scale workloads, it's not the most efficient approach for time-bound batch processing. Creating a separate namespace and applying resource quotas can limit resource usage, but doesn't directly address the intermittent nature of the workload. Manually scaling up and down is inefficient and prone to errors.
質問 # 64
What does "continuous" mean in the context of CI/CD?
正解：D
解説：
The correct answer is C: in CI/CD, "continuous" implies frequent releases, automation, repeatability, and fast feedback/processing. The intent is to reduce batch size and latency between code change and validation
/deployment. Instead of integrating or releasing in large, risky chunks, teams integrate changes continually and rely on automation to validate and deliver them safely.
"Continuous" does not mean "periodic" (which eliminates B and D). It also does not mean "manual processes" (which eliminates A and B). Automation is core: build, test, security checks, and deployment steps are consistently executed by pipeline systems, producing reliable outcomes and auditability.
In practice, CI means every merge triggers automated builds and tests so the main branch stays in a healthy state. CD means those validated artifacts are promoted through environments with minimal manual steps, often including progressive delivery controls (canary, blue/green), automated rollbacks on health signal failures, and policy checks. Kubernetes works well with CI/CD because it is declarative and supports rollout primitives: Deployments, readiness probes, and rollback revision history enable safer continuous delivery when paired with pipeline automation.
Repeatability is a major part of "continuous." The same pipeline should run the same way every time, producing consistent artifacts and deployments. This reduces "works on my machine" issues and shortens incident resolution because changes are traceable and reproducible. Fast processing and frequent releases also mean smaller diffs, easier debugging, and quicker customer value delivery.
So, the combination that accurately reflects "continuous" in CI/CD is frequent + automated + repeatable + fast, which is option C.
