Amazon DVA-C02 Exam - Topic 7 Question 31 Discussion

Actual exam question for Amazon's DVA-C02 exam

Question #: 31
Topic #: 7

A developer has an application that is composed of many different AWS Lambda functions. The Lambda functions all use some of the same dependencies. To avoid security issues the developer is constantly updating the dependencies of all of the Lambda functions. The result is duplicated effort to reach function.

How can the developer keep the dependencies of the Lambda functions up to date with the LEAST additional complexity?

ADefine a maintenance window for the Lambda functions to ensure that the functions get updated copies of the dependencies.

BUpgrade the Lambda functions to the most recent runtime version.

CDefine a Lambda layer that contains all of the shared dependencies.

DUse an AWS CodeCommit repository to host the dependencies in a centralized location.

Show Suggested Answer

Suggested Answer: B

DynamoDB Streams:Capture near real-time changes to DynamoDB tables, triggering downstream actions.

Lambda for Processing:Lambda functions provide a serverless way to execute code in response to events like DynamoDB Stream updates.

Minimal Code Changes:This solution requires the least modifications to the existing application.

Is it really that easy to manage dependencies with layers?

A maintenance window? Sounds like a hassle.

Upgrading the runtime version sounds tempting, but I don’t think it directly addresses the dependency management issue.

I think we practiced a similar question where using a centralized repository was mentioned, but I’m not convinced that CodeCommit is the right answer here.

I'm not entirely sure, but I feel like defining a maintenance window could just add more complexity instead of reducing it.

I remember discussing Lambda layers in class, and I think option C might be the best choice since it centralizes the dependencies.

Interesting, I hadn't considered using an AWS CodeCommit repository to host the dependencies. That could work, but I'm not sure if it would be less complex than the Lambda layer approach. Hmm, I'll have to think this one through a bit more.

Hmm, I'm a bit unsure about this one. Defining a maintenance window could work, but that might not be the most efficient approach. Upgrading the runtime version could be an option, but I'm not sure if that's the "least additional complexity" as the question asks for.

This seems like a straightforward question about managing dependencies in AWS Lambda. I think the key is to find a solution that minimizes the complexity of updating the dependencies across multiple functions.

Ah, I think the answer is to use a Lambda layer. That way, I can centralize the dependencies and update them in one place, instead of having to update each function individually. Seems like the simplest solution to me.

I think the key here is to focus on aligning the supplier SLAs with the overall service management plans. That seems like the most logical approach.

I'm feeling pretty confident about this one. Streaming the data to BigQuery and conducting a bulk scan using the DLP API seems like the most straightforward and efficient approach.

Upgrading the runtime version? What is this, the Stone Age? The Lambda layer is clearly the superior choice here. It's the 21st century, people!

Option C seems like the best choice to me. A Lambda layer would allow us to manage the dependencies centrally and automatically update the functions as needed.
