B : dify the TTL on the cache to a lower number

C : nd requests with the Cache-Control: max-age=0 header

D : nd requests with the Cache-Delete: max-age=0 header

Question 2

A company needs to package and deploy an application that uses AWS Lambda to compress and decompress video clips. The application uses a video codec library that is larger than 250 MB. The application uses the library to compress the videos before storage and to decompress the videos upon retrieval.

A : Create one Lambda function. Upload one zip file that contains code to handle video compression and decompression to the function. Include the codec library in the zip file

B : Create two Lambda functions. Upload one zip file that contains code to handle video compression to one function. Upload a second zip file that contains code for video decompression to the second function. Include the codec library in both zip files.

C : Create two Lambda functions. Upload one zip file that contains code to handle video compression to one function. Upload a second zip file that contains code for video decompression to the second function. Create one Lambda layer for the codec library. Add the layer to both functions.

D : Create two Lambda functions. Build one container image that contains code to handle video compression and a second image that contains video decompression code. Add the codec library to both images. Upload the images to Amazon ECR. Use the containers to create the Lambda functions.

Answer: D

Question 3

A developer built an application that calls an external API to obtain data, processes the data, and saves the result to Amazon S3. The developer built a container image with all of the necessary dependencies to run the application as a container.

The application runs locally and requires minimal CPU and RAM resources. The developer has created an Amazon ECS cluster. The developer needs to run the application hourly in Amazon Elastic Container Service (Amazon ECS).

Which solution will meet these requirements with the LEAST amount of infrastructure management overhead?

A : Add a capacity provider to manage instances.

B : Add an Amazon EC2 instance that runs the application.

C : Define a task definition with an AWS Fargate launch type.

D : Create an Amazon ECS cluster and add the managed node groups feature to run the application.

Answer: D

Question 4

Based on the following AWS CLI command the resulting output, what has happened here?

1. $ aws lambda invoke --function-name MyFunction --invocation-type Event --payload ewogICJrZXkxIjogInZhbHVlMSIsCiAgImtleTIiOiAidmFsdWUyIiwKICAia2V5MyI6ICJ2YWx1ZTMiCn0= response.json

2. {

C : AWS Lambda function has been invoked synchronously and has completed successfully

D : AWS Lambda function has been invoked asynchronously and has completed successfully

Answer: D

Question 5

A company wants to use AWS AppConfig to gradually deploy a new feature to 15% of users to test the feature before a full deployment. Which solution will meet this requirement with the LEAST operational overhead?

A : Set up a custom script within the application to randomly select 15% of users. Assign a flag for the new feature to the selected users.

B : Create separate AWS AppConfig feature flags for both groups of users. Configure the flags to target 15% of users.

C : Create an AWS AppConfig feature flag. Define a variant for the new feature, and create a rule to target 15% of users.

D : Use AWS AppConfig to create a feature flag without variants. Implement a custom traffic splitting mechanism in the application code.
