A company has multiple AWS accounts with applications deployed in the us-west-2 Region Application logs are stored within Amazon S3 buckets in each account. The company wants to build a centralized log analysts solution that uses a single S3 bucket Logs must not leave us-west-2T and the company wants to incur minimal operational overhead.
Which solution meets these requirements and is MOST cost-effective?

• A.Create an S3 Lifecycle policy that copies the objects from one of the application S3 buckets to the centralized S3 bucket
• B.Write AWS Lambda functions in these accounts that are triggered every time logs ate delivered to the S3 buckets (s3 ObjectCreated. * event) Copy the logs to another S3 bucket in us-west-2 Use this S3 bucket for log analysis
• C.Use S3 Same-Region Replication to replicate logs from the S3 buckets to another S3 bucket in us-west-2 Use this S3 bucket for log analysis
• D.Write a script that uses the PutObject API operation every day to copy the entire contents of the buckets to another S3 bucket in us-west-2 Use this S3 bucket for log analysis

A company provides an API to its users trial automates inquires for tax computations based on item prices.
The company experiences a larger number of inquiries during the holiday season only that cause slower response times. A solutions architect needs to design a solution that is scalable and elastic.
What should the solution architect do lo accompli this?

• A.Create an Application Load Balancer mat has two Amazon EC2 instances behind it. The EC2 instances will compute the tax on the received Hem names.
• B.Provide an API hosted on an Amazon EC2 Instance. The EC2 instance performs the required computations when the API request is made.
• C.Design a REST API using Amazon API Gateway mat accepts the item names API Gateway passes item names to AWS Lambda for tax computations
• D.Design a REST API using Amazon API Gateway that connects with an API hosted on an Amazon EC2 instance. API Gateway accepts and passes the item names to the EC2 instance for tax computations

• C.Create an Auto Scaling group that uses three instances across each of two Regions
• D.Create an Auto Scaling template that can be used to quickly create more instances in another Region
