1. A company needs to share an Amazon S3 bucket with an external vendor. The bucket owner must be able to access all objects. Which action should be taken to share the S3 bucket?

A) Create a bucket policy to require users to grant bucket-owner-full-control when uploading objects.
B) Create an IAM policy to require users to grant bucket-owner-full-control when uploading objects.
C) Update the bucket to enable cross-origin resource sharing (CORS).
D) Update the bucket to be a Requester Pays bucket.



2. A company has a custom application running on an Amazon EC instance that: - Reads a large amount of data from Amazon S3 - Performs a multi-stage analysis - Writes the results to Amazon DynamoDB. The application writes a significant number of large temporary files during the multi-stage analysis. The process performance depends on the temporary storage performance. What would be the fastest storage option for holding the temporary files?

A) Multiple Amazon EBS drives with Provisioned IOPS and EBS optimization.
B) Multiple instance store volumes with software RAID 0.
C) Multiple Amazon S3 buckets with Transfer Acceleration for storage.
D) Multiple Amazon EFS volumes using the Network I lie System version 4.1 (NFSv4.1) protocol.



3. A company is concerned that two NAT instances in use will no longer be able to support the traffic needed for the company's application. A solutions architect wants to implement a solution that is highly available fault tolerant, and automatically scalable. What should the solutions architect recommend?

A) Remove the two NAT instances and replace them with two NAT gateways in the same Availability Zone.
B) Replace the two NAT instances with Spot Instances in different Availability Zones and deploy a Network Load Balancer.
C) Use Auto Scaling groups with Network Load Balancers for the NAT instances in different Availability Zones.
D) Remove the two NAT instances and replace them with two NAT gateways in different Availability Zones.



4. A company decides to migrate its three-tier web application from on-premises to the AWS Cloud. The new database must be capable of dynamically scaling storage capacity and performing table joins.Which AWS service meets these requirements?

A) Amazon DynamoDB Streams
B) Amazon RDS for SqlServer
C) Amazon Aurora
D) Amazon DynamoDB on-demand



5. A company has been storing analytics data in an Amazon RDS instance for the past few years. The company asked a solutions architect to find a solution that allows users to access this data using an API. The expectation is that the application will experience periods of inactivity but could receive bursts of traffic within seconds.Which solution should the solutions architect suggest?

A) Set up an Amazon API Gateway and use Amazon ECS.
B) Set up an Amazon API Gateway and use AWS Lambda functions.
C) Set up an Amazon API Gateway and use AWS Elastic Beanstalk.
D) Set up an Amazon API Gateway and use Amazon EC2 with Auto Scaling.
