Question 1

A company uses an AWS Lambda function to perform natural language processing (NLP) tasks. The company has attached a Lambda layer to the function. The Lambda layer contain scientific libraries that the function uses during processing.

The company added a large, pre-trained text-classification model to the Lambda layer. The addition increased the size of the Lambda layer to 8.7 GB. After the addition and a recent deployment, the Lambda function returned a RequestEntityTooLargeException error.

The company needs to update the Lambda function with a high-performing and portable solution to decrease the initialization time for the function.

Which solution will meet these requirements?

Options:

A.

Store the large pre-trained model in an Amazon S3 bucket. Use the AWS SDK to access the model.

B.

Create an Amazon EFS file system to store the large pre-trained model. Mount the file system to an Amazon EC2 instance. Configure the Lambda function to use the EFS file system.

C.

Split the components of the Lambda layer into five new Lambda layers. Zip the new layers, and attach the layers to the Lambda function. Update the function code to use the new layers.

D.

Create a Docker container that includes the scientific libraries and the pre-trained model. Update the Lambda function to use the container image.

A developer created several AWS Lambda functions that write data to a single Amazon S3 bucket. The developer configured all the Lambda functions to send logs and metrics to Amazon CloudWatch.

The developer receives reports that one of the Lambda functions writes data to the bucket very slowly. The developer needs to measure the latency between the problematic Lambda function and the S3 bucket.

Which solution will meet this requirement?

Options:

A.

Enable AWS X-Ray on the Lambda function. In the generated trace map. select the line between Lambda and Amazon S3.

B.

Query the Lambda function's log file in Amazon CloudWatch Logs Insights. Return the average of the auto-discovered ©duration field.

C.

Enable CloudWatch Lambda Insights on the function. View the latency graph that CloudWatch Lambda Insights provides.

D.

Enable AWS X-Ray on the Lambda function. Select Amazon S3 in the latency graph to view the latency histogram.
