最新的 Kubernetes Cloud Native Associate KCNA 免費考試真題 (Q49-Q54):

問題 #49
Which of the following is an advantage a cloud-native microservices application has over monolithic applications?

A. Cloud-native microservice applications tend to be easier to scale and perform updates on.
B. Cloud-native microservice applications tend to be easier to troubleshoot.
C. Cloud-native microservices applications tend to be faster and more responsive than monolithic applications.

答案：A

解題說明：
Cloud-native applications tend to be microservice base, they have individual services that can be independently scaled, updated and rolled back. This makes scaling and update operations simpler and less risky.

問題 #50
You're designing a serverless application that processes large amounts of data using AWS Lambd
a. You need to ensure that your Lambda functions can handle potential spikes in workload without compromising performance. Which of the following approaches would be most effective in achieving this goal?

A. Implement a message queue in front of Lambda functions to buffer incoming requests.
B. Utilize AWS Elastic Beanstalk to auto-scale Lambda functions based on workload.
C. Configure Lambda functions to use a larger memory allocation.
D. Enable concurrency settings for Lambda functions to allow multiple invocations simultaneously.
E. Use serverless frameworks like AWS Serverless Application Model (SAM) to manage Lambda deployments.

答案：A,D

解題說明：
The most effective approaches to handle workload spikes are implementing a message queue (like SQS or SNS) to buffer requests and enabling concurrency settings on Lambda functions. Option A increases memory but doesn't address scalability. Option C is not relevant to Lambda auto-scaling. Option D is a deployment tool, not directly related to handling workload spikes. Option E directly enables parallel processing, making it a suitable solution.

問題 #51
