A company is migrating legacy internal applications to AWS. Leadership wants to rewrite the internal employee directory to use native AWS services. A developer needs to create a solution for storing employee contact details and high-resolution photos for use with the new application.
Which solution will enable the search and retrieval of each employee's individual details and high-resolution photos using AWS APIs?

1. A. Encode each employee's contact information and photos using Base64. Store the information in an Amazon DynamoDB table using a sort key.
2. B. Store each employee's contact information in an Amazon DynamoDB table along with the object keys for the photos stored in Amazon S3.
3. C. Use Amazon Cognito user pools to implement the employee directory in a fully managed software-as-a-service (SaaS) method.
4. D. Store employee contact information in an Amazon RDS DB instance with the photos stored in Amazon Elastic File System (Amazon EFS).

A company hosts a client-side web application for one of its subsidiaries on Amazon S3. The web application can be accessed through Amazon CloudFront from https://www.example.com. After a successful rollout, the company wants to host three more client-side web applications for its remaining subsidiaries on three separate S3 buckets.
To achieve this goal, a developer moves all the common JavaScript files and web fonts to a central S3 bucket that serves the web applications. However, during testing, the developer notices that the browser blocks the JavaScript files and web fonts.
What should the developer do to prevent the browser from blocking the JavaScript files and web fonts?

1. A. Create four access points that allow access to the central S3 bucke
2. B. Assign an access point to each web application bucket.
3. C. Create a bucket policy that allows access to the central S3 bucke
4. D. Attach the bucket policy to the central S3 bucket.
5. E. Create a cross-origin resource sharing (CORS) configuration that allows access to the central S3 bucket.Add the CORS configuration to the central S3 bucket.
6. F. Create a Content-MD5 header that provides a message integrity check for the central S3 bucke
7. G. Insert the Content-MD5 header for each web application request.

Correct Answer: C

1. A. Create an Amazon ElastiCache for Redis instanc
2. B. Enable encryption of data in transit and at res
3. C. Store frequently accessed data in the cache.
4. D. Create an Amazon ElastiCache for Memcached instanc
5. E. Enable encryption of data in transit and at rest.Store frequently accessed data in the cache.
6. F. Create an Amazon RDS for MySQL read replic
7. G. Connect to the read replica by using SS
8. H. Configure the read replica to store frequently accessed data.
9. I. Create an Amazon DynamoDB table and a DynamoDB Accelerator (DAX) cluster for the tabl
10. J. Store frequently accessed data in the DynamoDB table.
