A website's page load times are gradually increasing as more users access the system at the same time. Analysis indicates that a user profile is being loaded from a database in all the web pages being visited by each user and this is increasing the database load and the page load latency. To address this issue the Developer decides to cache the user profile data.
Which caching strategy will address this situation MOST efficiently?

• A.Create a new Amazon EC2 Instance and run a NoSQL database on it. Cache the profile data within this database using the write-through caching strategy.
• B.Create an Amazon ElastiCache cluster to cache the user profile data. Use a cache-aside caching strategy.
• C.Use a dedicated Amazon RDS instance for caching profile data. Use a write-through caching strategy.
• D.Create an ElastiCache cluster to cache the user profile data. Use a write-through caching strategy.

An application is running on a cluster of Amazon EC2 instance. While trying to read objects stored within a single Amazon S3 bucket that are encrypted with server-side encryption with AWS KMS managed keys (SSE-KMS), the application receives the following error:
Service : AWSKMS: Status Code: 400: Code : ThrottlingException
Which combination of steps should be taken to prevent this failure? (Select TWO.)

• A.Perform error retries with exponential backoff in the application code.
• B.Use more than one customer master key (CMK) to encrypt S3 data
• C.Import a customer master key (CMK) with a larger key size.
• D.Contact AWS Support to request a S3 rate limit increase.
• E.Contact AWS Support to request an AWS KMS rate limit increase.

A company hosts a monolithic application on Amazon EC2 instances. The company starts converting some features of the application to a serverless architecture by using Amazon API Gateway and AWS Lambda After the migration, some users report problems with payment processing Upon inspection, a developer discovers that the Lambda function that calls the external payment API is taking longer than expected Therefore, the API Gateway requests are timing out What should the developer do to resolve this issue in the serverless architecture1?

• A.Use Amazon Simple Queue Service (Amazon SQS) with API Gateway and the Lambda function to asynchronously call the payment API
• B.Increase the Lambda function's memory to increase the network bandwidth and increase the speed of the payment API calls
• C.Increase the API Gateway timeout duration to match the payment API time
• D.Use the EC2 instances to make the API calls to the payment API
