To remain under the package size limit, the dependencies were not included in the deployment file. When testing the application remotely, the function does not execute because of missing dependencies. Which approach would resolve the issue? Options : a) Use the Lambda console editor to update the code and include the missing dependencies b) Create an additional zip file with the missing dependencies and include the file in the original Lambda deployment package c) Add references to the missing dependencies in the Lambda function's environment variables d) Attach a layer to the Lambda function that contains the missing dependencies Become successful with VMExam.com Answer d) Attach a layer to the Lambda function that contains the missing dependencies. Become successful with VMExam.com Que.05: A developer is building a web application that uses Amazon API Gateway. The developer wants to maintain different environments for development and production (dev and prod) workloads. The API will be backed by an AWS Lambda function with two aliases: one for dev and one for prod. How can this be achieved with the LEAST amount of configuration? Options : a) Create a REST API for each environment and integrate the APIs with the corresponding dev and prod aliases of the Lambda function Then deploy the two APIs to their respective stages and access them using the stage URLs b) Create one REST API and integrate it with the Lambda function using a stage variable in place of an alias Then deploy the API to two different stages – dev and prod – and create a stage variable in each stage with different aliases as the values Access the API using the different stage URLs c) Create one REST API and integrate it with the dev alias of the Lambda function, and deploy it to a dev environment Configure a canary release deployment for prod where the canary will integrate with the Lambda prod alias d) Create one REST API and integrate it with the prod alias of the Lambda function and deploy it to a prod environment Configure a canary release deployment for dev where the canary will integrate with the Lambda dev alias Become successful with VMExam.com Answer b) Create one REST API and integrate it with the Lambda function using a stage variable in place of an alias.
