A large company is migrating its on-premises applications to the AWS Cloud. All the company's AWS accounts belong to an organization in AWS Organizations.
Each application is deployed into its own VPC in separate AWS accounts.
The company decides to start the migration process by migrating the front-end web services while keeping the databases on premises. The databases are configured with local domain names that are specific to the on-premises environment. The local domain names must be resolvable from the migrated web services.
Which solution will meet these requirements with the LEAST operational overhead?
  • A. Create a shared services VPC in a new AWS account. Deploy Amazon Route 53 outbound resolvers. For relevant on-premises domains, use the outbound resolver settings to create forwarding rules that point to the on-premises DNS servers. Share these rules with the other AWS accounts by using AWS Resource Access Manager.
  • B. Deploy Multi-AZ Amazon Route 53 outbound resolvers in each VPC. Create forwarding rules that point to on-premises DNS servers in local outbound resolvers for each VPC.
  • C. Create a shared services VPC in a new AWS account. Deploy Amazon EC2 instances that act conditional forwarders inside the shared services VPC. Change the DHCP options set in each VPC to point to these forwarders as DNS servers. Create forwarding rules for relevant on-premises domains in these forwarders.
  • D. Create a shared services VPC in a new AWS account. Deploy Amazon Route 53 inbound resolvers. For relevant on-premises domains, create forwarding rules that point to on-premises DNS servers. Share these rules with other AWS accounts by using AWS Resource Access Manager.

A company has a media metadata extraction pipeline running on AWS. Notifications containing a reference to a file in Amazon S3 are sent to an Amazon Simple
Notification Service (Amazon SNS) topic. The pipeline consists of a number of AWS Lambda functions that are subscribed to the SNS topic. The Lambda functions extract the S3 tile and write metadata to an Amazon RDS PostgreSQL DB instance.
Users report that updates to the metadata are sometimes slow to appear or are lost. During these times, the CPU utilization on the database is high and the number of failed Lambda invocations increases.
Which combination of actions should a solutions architect take to help resolve this issue? (Choose two.)
  • A. Enable message delivery status on the SNS topic. Configure the SNS topic delivery policy to enable retries with exponential backoff.
  • B. Create an Amazon Simple Queue Service (Amazon SQS) FIFO queue and subscribe the queue to the SNS topic. Configure the Lambda functions to consume messages from the SQS queue.
  • C. Create an RDS proxy for the RDS instance. Update the Lambda functions to connect to the RDS instance using the proxy.
  • D. Enable the RDS Data API for the RDS instance. Update the Lambda functions to connect to the RDS instance using the Data API.
  • E. Create an Amazon Simple Queue Service (Amazon SQS) standard queue for each Lambda function and subscribe the queues to the SNS topic. Configure the Lambda functions to consume messages from their respective SQS queue.

An ecommerce website running on AWS uses an Amazon RDS for MySQL DB instance with General Purpose SSD storage. The developers chose an appropriate instance type based on demand, and configured 100 GB of storage with a sufficient amount of free space.
The website was running smoothly for a few weeks until a marketing campaign launched. On the second day of the campaign, users reported long wait times and time outs. Amazon CloudWatch metrics indicated that both reads and writes to the DB instance were experiencing long response times. The CloudWatch metrics show 40% to 50% CPU and memory utilization, and sufficient free storage space is still available. The application server logs show no evidence of database connectivity issues.
What could be the root cause of the issue with the marketing campaign?
  • A. It exhausted the I/O credit balance due to provisioning low disk storage during the setup phase.
  • B. It caused the data in the tables to change frequently, requiring indexes to be rebuilt to optimize queries.
  • C. It exhausted the maximum number of allowed connections to the database instance.
  • D. It exhausted the network bandwidth available to the RDS for MySQL DB instance.
