Question 76

A retail company is hosting an ecommerce website on AWS across multiple AWS Regions. The company wants the website to be operational at all times for online purchases. The website stores data in an Amazon RDS for MySQL DB instance. Which solution will provide the HIGHEST availability for the database?

  1. Configure automated backups on Amazon RDS. In the case of disruption, promote an automated backup to be a standalone DB instance. Direct database traffic to the promoted DB instance. Create a replacement read replica that has the promoted DB instance as its source.
  2. Configure global tables and read replicas on Amazon RDS. Activate the cross-Region scope. In the case of disruption, use AWS Lambda to copy the read replicas from one Region to another Region.
  3. Configure global tables and automated backups on Amazon RDS. In the case of disruption, use AWS Lambda to copy the read replicas from one Region to another Region.
  4. Configure read replicas on Amazon RDS. In the case of disruption, promote a cross-Region and read replica to be a standalone DB instance. Direct database traffic to the promoted DB instance. Create a replacement read replica that has the promoted DB instance as its source.

Question 77

Example Corp. has an on-premises data center and a VPC named VPC A in the Example Corp. AWS account. The on-premises network connects to VPC A through an AWS Site-To-Site VPN. The on-premises servers can properly access VPC A. Example Corp. just acquired AnyCompany, which has a VPC named VPC B. There is no IP address overlap among these networks. Example Corp. has peered VPC A and VPC B. Example Corp. wants to connect from its on-premise servers to VPC B. Example Corp. has properly set up the network ACL and security groups. Which solution will meet this requirement with the LEAST operational effort?

  1. Create a transit gateway. Attach the Site-to-Site VPN, VPC A, and VPC B to the transit gateway. Update the transit gateway route tables for all networks to add IP range routes for all other networks.
  2. Create a transit gateway. Create a Site-to-Site VPN connection between the on-premises network and VPC B, and connect the VPN connection to the transit gateway. Add a route to direct traffic to the peered VPCs, and add an authorization rule to give clients access to the VPCs A and B.
  3. Update the route tables for the Site-to-Site VPN and both VPCs for all three networks. Configure BGP propagation for all three networks. Wait for up to 5 minutes for BGP propagation to finish.
  4. Modify the Site-to-Site VPN’s virtual private gateway definition to include VPC A and VPC B. Split the two routers of the virtual private getaway between the two VPCs.

Question 78

A company recently completed the migration from an on-premises data center to the AWS Cloud by using a replatforming strategy. One of the migrated servers is running a legacy Simple Mail Transfer Protocol (SMTP) service that a critical application relies upon. The application sends outbound email messages to the company’s customers. The legacy SMTP server does not support TLS encryption and uses TCP port 25. The application can use SMTP only. The company decides to use Amazon Simple Email Service (Amazon SES) and to decommission the legacy SMTP server. The company has created and validated the SES domain. The company has lifted the SES limits. What should the company do to modify the application to send email messages from Amazon SES?

  1. Configure the application to connect to Amazon SES by using TLS Wrapper. Create an IAM role that has ses:SendEmail and ses:SendRawEmail permissions. Attach the IAM role to an Amazon EC2 instance.
  2. Configure the application to connect to Amazon SES by using STARTTLS. Obtain Amazon SES SMTP credentials. Use the credentials to authenticate with Amazon SES.
  3. Configure the application to use the SES API to send email messages. Create an IAM role that has ses:SendEmail and ses:SendRawEmail permissions. Use the IAM role as a service role for Amazon SES.
  4. Configure the application to use AWS SDKs to send email messages. Create an IAM user for Amazon SES. Generate API access keys. Use the access keys to authenticate with Amazon SES.

Question 79

A company recently acquired several other companies. Each company has a separate AWS account with a different billing and reporting method. The acquiring company has consolidated all the accounts into one organization in AWS Organizations. However, the acquiring company has found it difficult to generate a cost report that contains meaningful groups for all the teams. The acquiring company’s finance team needs a solution to report on costs for all the companies through a self-managed application. Which solution will meet these requirements?

  1. Create an AWS Cost and Usage Report for the organization. Define tags and cost categories in the report. Create a table in Amazon Athena. Create an Amazon QuickSight dataset based on the Athena table. Share the dataset with the finance team.
  2. Create an AWS Cost and Usage Report for the organization. Define tags and cost categories in the report. Create a specialized template in AWS Cost Explorer that the finance department will use to build reports.
  3. Create an Amazon QuickSight dataset that receives spending information from the AWS Price List Query API. Share the dataset with the finance team.
  4. Use the AWS Price List Query API to collect account spending information. Create a specialized template in AWS Cost Explorer that the finance department will use to build reports.

Question 80

A company runs an IoT platform on AWS. IoT sensors in various locations send data to the company’s Node.js API servers on Amazon EC2 instances running behind an Application Load Balancer. The data is stored in an Amazon RDS MySQL DB instance that uses a 4 TB General Purpose SSD volume. The number of sensors the company has deployed in the field has increased over time, and is expected to grow significantly. The API servers are consistently overloaded and RDS metrics show high write latency. Which of the following steps together will resolve the issues permanently and enable growth as new sensors are provisioned, while keeping this platform cost-efficient? (Choose two.)

  1. Resize the MySQL General Purpose SSD storage to 6 TB to improve the volume’s IOPS.
  2. Re-architect the database tier to use Amazon Aurora instead of an RDS MySQL DB instance and add read replicas.
  3. Leverage Amazon Kinesis Data Streams and AWS Lambda to ingest and process the raw data.
  4. Use AWS X-Ray to analyze and debug application issues and add more API servers to match the load.
  5. Re-architect the database tier to use Amazon DynamoDB instead of an RDS MySQL DB instance.
