Question 1

A company provides an API to its users that automates inquiries 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 solutions architect do to accomplish this?

Options :

A :

Provide an API hosted on an Amazon EC2 instance. The EC2 instance performs the required computations when the API request is made.

B :

Design a REST API using Amazon API Gateway that accepts the item names. API Gateway passes item names to AWS Lambda for tax computations.

C :

Create an Application Load Balancer that has two Amazon EC2 instances behind it. The EC2 instances will compute the tax on the received item names.

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

Answer: B

Question 2

A company runs an application in a VPC with public and private subnets. The VPC extends across multiple Availability Zones. The application runs on Amazon EC2 instances in private subnets. The application uses an Amazon Simple Queue Service (Amazon SQS) queue.A solutions architect needs to design a secure solution to establish a connection between the EC2 instances and the SQS queue.Which solution will meet these requirements?

Options :

A : mplement an interface VPC endpoint for Amazon SQS. Configure the endpoint to use the private subnets. Add to the endpoint a security group that has an inbound access rule that allows traffic from the EC2 instances that are in the private subnets.

B : Implement an interface VPC endpoint for Amazon SQS. Configure the endpoint to use the public subnets. Attach to the interface endpoint a VPC endpoint policy that allows access from the EC2 instances that are in the private subnets.

C : Implement an interface VPC endpoint for Amazon SQS. Configure the endpoint to use the public subnets. Attach an Amazon SQS access policy to the interface VPC endpoint that allows requests from only a specified VPC endpoint.

D : Implement a gateway endpoint for Amazon SQS. Add a NAT gateway to the private subnets. Attach an IAM role to the EC2 instances that allows access to the SQS queue.

Answer: A

Question 3

The company you are working for has a set of AWS resources hosted in ap-northeast-1 region. You have been asked by your IT Manager to create an AWS CLI shell script that will call an AWS service which could create duplicate resources in another region in the event that ap-northeast-1 region fails. The duplicated resources should also contain the VPC Peering configuration and other networking components from the primary stack.Which of the following AWS services could help fulfill this task?

Options :

A : Amazon SNS

B : Amazon SQS

C : AWS CloudFormation

D : AWS Elastic Beanstalk

Answer: C

Question 4

A company has a license-based, expensive, legacy commercial database solution deployed at its on-premises data center. The company wants to migrate this database to a more efficient, open-source, and cost-effective option on AWS Cloud. The CTO at the company wants a solution that can handle complex database configurations such as secondary indexes, foreign keys, and stored procedures.

As a solutions architect, which of the following AWS services should be combined to handle this use-case? (Select two)

Options :

A : AWS Snowball Edge

B : AWS Glue

C : AWS Database Migration Service (AWS DMS)

D : Basic Schema Copy

E : AWS Schema Conversion Tool (AWS SCT)

Answer: C,E

Question 5

A company has thousands of edge devices that collectively generate 1 TB of status alerts each day. Each alert is approximately 2 KB in size. A solutions architect needs to implement a solution to ingest and store the alerts for future analysis. The company wants a highly available solution. However, the company needs to minimize costs and does not want to manage additional infrastructure. Additionally, the company wants to keep 14 days of data available for immediate analysis and archive any data older than 14 days. What is the MOST operationally efficient solution that meets these requirements?

Options :

A : Create an Amazon Kinesis Data Firehose delivery stream to ingest the alerts. Configure the Kinesis Data Firehose stream to deliver the alerts to an Amazon S3 bucket. Set up an S3 Lifecycle configuration to transition data to Amazon S3 Glacier after 14 days.

B : Launch Amazon EC2 instances across two Availability Zones and place them behind an Elastic Load Balancer to ingest the alerts. Create a script on the EC2 instances that will store the alerts in an Amazon S3 bucket. Set up an S3 Lifecycle configuration to transition data to Amazon S3 Glacier after 14 days

C : Create an Amazon Kinesis Data Firehose delivery stream to ingest the alerts. Configure the Kinesis Data Firehose stream to deliver the alerts to an Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster. Set up the Amazon OpenSearch Service (Amazon Elasticsearch Service) cluster to take manual snapshots every day and delete data from the cluster that is older than 14 days.

D : Create an Amazon Simple Queue Service (Amazon SQS) standard queue to ingest the alerts, and set the message retention period to 14 days. Configure consumers to poll the SQS queue, check the age of the message, and analyze the message data as needed. If the message is 14 days old, the consumer should copy the message to an Amazon S3 bucket and delete the message from the SQS queue.
