QUESTION 1
Company C has recently launched an online commerce site for bicycles on AWS. They have a "Product" DynamoDB
table that stores details for each bicycle, such as, manufacturer, color, price, quantity and size to display in the online
store. Due to customer demand, they want to include an image for each bicycle along with the existing details.
Which approach below provides the least impact to provisioned throughput on the "Product" table?
A. Serialize the image and store it in multiple DynamoDB tables
B. Create an "Images" DynamoDB table to store the Image with a foreign key constraint to the "Product" table
C. Add an image data type to the "Product" table to store the images in binary format
D. Store the images in Amazon S3 and add an S3 URL pointer to the "Product" table item for each image
Correct Answer: D
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-use-s3-too.html#bp-use-s3-too-large-values
For example, consider the ProductCatalog table in the Creating Tables and Loading Data for Code Examples in
DynamoDB section. Items in this table store information about item price, description, book authors, and dimensions for
other products. If you wanted to store an image of each product that was too large to fit in an item, you could store the
images in Amazon S3 instead of in DynamoDB.
QUESTION 2
An application uses Lambda functions to extract metadata from files uploaded to an S3 bucket; the metadata is stored in
Amazon DynamoDB. The application starts behaving unexpectedly, and the Developer wants to examine the logs of the
Lambda function code for errors.
Based on this system configuration, where would the Developer find the logs?
A. Amazon S3
B. AWS CloudTrail
C. Amazon CloudWatch
D. Amazon DynamoDB
Correct Answer: C
QUESTION 3
A global company has an application running on Amazon EC2 instances that serves image files from Amazon S3. User
requests from the browser are causing high traffic, which results in degraded performance. Which optimization solution
should a Developer implement to increase application performance?
A. Create multiple prefix in the S3 bucket to increase the request rate
B. Create an Amazon ElastiCache cluster to cache and serve frequently accessed items.
