Question 1/101/10
A company uses a service to collect metadata from applications that the company hosts on premises.
Consumer devices such as TVs and internet radios access the applications. Many older devices do not
support certain HTTP headers and exhibit errors when these headers are present in responses. The
company has configured an on-premises load balancer to remove the unsupported headers from
responses sent to older devices, which the company identified by the User-Agent headers.
The company wants to migrate the service to AWS, adopt serverless technologies, and retain the
ability to support the older devices. The company has already migrated the applications into a set of
AWS Lambda functions.
Which solution will meet these requirements?

Question 2/102/10
A company is running a traditional web application on Amazon EC2 instances. The company needsto
refactor the application as microservices that run on containers. Separate versions of the application
exist in two distinct environments: production and testing. Load for the application is variable, but
the minimum load and the maximum load are known. A solutions architect needs to design the
updated application with a serverless architecture that minimizes operational complexity.

Question 3/103/10
A company has a multi-tier web application that runs on a fleet of Amazon EC2 instances behind an
Application Load Balancer (ALB). The instances are in an Auto Scaling group. The ALB and the Auto
Scaling group are replicated in a backup AWS Region. The minimum value and the maximum value
for the Auto Scaling group are set to zero. An Amazon RDS Multi-AZ DB instance stores the
application’s dat
a. The DB instance has a read replica in the backup Region. The application presents an endpoint to
end users by using an Amazon Route 53 record.
The company needs to reduce its RTO to less than 15 minutes by giving the application the ability to
automatically fail over to the backup Region. The company does not have a large enough budget for
an active-active strategy.
What should a solutions architect recommend to meet these requirements?

Select the answer:Select the answer
1 correct answerA.
Reconfigure the application’s Route 53 record with a latency-based routing policy that load balances traffic between the two ALBs. Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Create an Amazon CloudWatch alarm that is based on the HTTPCode_Target_5XX_Count metric for the ALB in the primary Region. Configure the CloudWatch alarm to invoke the Lambda function.
B.
Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Configure Route 53 with a health check that monitors the web application and sends an Amazon Simple Notification Service (Amazon SNS) notification to the Lambda function when the health check status is unhealthy. Update the application’s Route 53 record with a failover policy that routes traffic to the ALB in the backup Region when a health check failure occurs.
C.
Configure the Auto Scaling group in the backup Region to have the same values as the Auto Scaling group in the primary Region. Reconfigure the application’s Route 53 record with a latency-based routing policy that load balances traffic between the two ALBs. Remove the read replica. Replace the read replica with a standalone RDS DB instance. Configure Cross-Region Replicationbetween the RDS DB instances by using snapshots and Amazon S3.
D.
Configure an endpoint in AWS Global Accelerator with the two ALBs as equal weighted targets. Create an AWS Lambda function in the backup Region to promote the read replica and modify the Auto Scaling group values. Create an Amazon CloudWatch alarm that is based on the HTTPCode_Target_5XX_Count metric for the ALB in the primary Region. Configure the CloudWatch alarm to invoke the Lambda function.

Question 4/104/10
A company is hosting a critical application on a single Amazon EC2 instance. The application uses an
Amazon ElastiCache for Redis single-node cluster for an in-memory data store. The application uses

Question 5/105/10
A retail company is operating its ecommerce application on AWS. The application runs on Amazon
EC2 instances behind an Application Load Balancer (ALB). The company uses an Amazon RDS DB
instance as the database backend. Amazon CloudFront is configured with one origin that points to
the ALB. Static content is cached. Amazon Route 53 is used to host all public zones.
After an update of the application, the ALB occasionally returns a 502 status code (Bad Gateway)
error. The root cause is malformed HTTP headers that are returned to the ALB. The webpage returns
successfully when a solutions architect reloads the webpage immediately after the error occurs.
While the company is working on the problem, the solutions architect needs to provide a custom
error page instead of the standard ALB error page to visitors.
Which combination of steps will meet this requirement with the LEAST amount of operational
overhead? (Choose two.)
