Amazon Exam DVA-C02 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.

That's a good point, Lai. But wouldn't defining a Lambda layer be more efficient in the long run?

I disagree, I believe option B is the way to go. Upgrading the runtime version would automatically update the dependencies.

I think option C is the best choice. It would reduce duplicated effort and ensure all functions have the same dependencies.
