Question 1

A company's software development team needs an Amazon RDS Multi-AZ cluster. The RDS cluster will serve as a backend for a desktop client that is deployed on premises. The desktop client requires direct connectivity to the RDS cluster. The company must give the development team the ability to connect to the cluster by using the client when the team is in the office. Which solution provides the required connectivity MOST securely?

Options :

A : Create a VPC and two public subnets. Create the RDS cluster in the public subnets. Use AWS Site-toSite VPN with a customer gateway in the company-s office.

B : Create a VPC and two private subnets. Create the RDS cluster in the private subnets. Use AWS Site-toSite VPN with a customer gateway in the company-s office.

C :

Create a VPC and two private subnets. Create the RDS cluster in the private subnets. Use RDS security groups to allow the company-s office IP ranges to access the cluster.

D :

Create a VPC and two public subnets. Create the RDS cluster in the public subnets. Create a cluster user for each developer. Use RDS security groups to allow the users to access the cluster.

Answer: B

Question 2

A company wants to store business-critical data on Amazon Elastic Block Store (Amazon EBS) volumes which provide persistent storage independent of Amazon EC2 instances. During a test run, the development team found that on terminating an Amazon EC2 instance, the attached Amazon EBS volume was also lost, which was contrary to their assumptions.

As a solutions architect, could you explain this issue?

Options :

A : The Amazon EBS volumes were not backed up on Amazon EFS file system storage, resulting in the loss of volume

B : The Amazon EBS volume was configured as the root volume of Amazon EC2 instance. On termination of the instance, the default behavior is to also terminate the attached root volume

C : On termination of an Amazon EC2 instance, all the attached Amazon EBS volumes are always terminated

D : The Amazon EBS volumes were not backed up on Amazon S3 storage, resulting in the loss of volume

Answer: B

Question 3

A company is migrating an on-premises application to AWS. The company wants to use Amazon Redshift as a solution.

Which use cases are suitable for Amazon Redshift in this scenario? (Choose three.)

Options :

A : Supporting data APIs to access data with traditional, containerized, and event-driven applications

B : Supporting client-side and server-side encryption

C : Building analytics workloads during specified hours and when the application is not active

D : Caching data to reduce the pressure on the backend database

E : Scaling globally to support petabytes of data and tens of millions of requests per minute

F : Creating a secondary replica of the cluster by using the AWS Management Console

Answer: B,C,E

Question 4

A solutions architect is designing a new API using Amazon API Gateway that will receive requests from users. The volume of requests is highly variable; several hours can pass without receiving a single request. The data processing will take place asynchronously, but should be completed within a few seconds after a request is made.

Which compute service should the solutions architect have the API invoke to deliver the requirements at the lowest cost?

Options :

A : An AWS Glue job

B : An AWS Lambda function

C : A containerized service hosted in Amazon Elastic Kubernetes Service (Amazon EKS)

D : A containerized service hosted in Amazon ECS with Amazon EC2

Answer: B

Question 5

A bicycle sharing company is developing a multi-tier architecture to track the location of its bicycles during peak operating hours. The company wants to use these data points in its existing analytics platform. A solutions architect must determine the most viable multi-tier option to support this architecture. The data points must be accessible from the REST API. Which action meets these requirements for storing and retrieving location data?

Options :

A : Use Amazon Athena with Amazon S3.

B : Use Amazon API Gateway with AWS Lambda.

C : Use Amazon QuickSight with Amazon Redshift.

D : Use Amazon API Gateway with Amazon Kinesis Data Analytics.

Answer: D
