AWS Certified Solutions Architect - Associate (SAA-C03) Questions and Answers

Question 145

A gaming company is designing a highly available architecture. The application runs on a modified Linux kernel and supports only UDP-based traffic. The company needs the front-end tier to provide the best possible user experience. That tier must have low latency, route traffic to the nearest edge location, and provide static IP addresses for entry into the application endpoints.

What should a solutions architect do to meet these requirements?

Options:

A.

Configure Amazon Route 53 to forward requests to an Application Load Balancer. Use AWS Lambda for the application in AWS Application Auto Scaling.

B.

Configure Amazon CloudFront to forward requests to a Network Load Balancer. Use AWS Lambda for the application in an AWS Application Auto Scaling group.

C.

Configure AWS Global Accelerator to forward requests to a Network Load Balancer. Use Amazon EC2 instances for the application in an EC2 Auto Scaling group.

D.

Configure Amazon API Gateway to forward requests to an Application Load Balancer. Use Amazon EC2 instances for the application in an EC2 Auto Scaling group.

Question 146

A company wants to direct its users to a backup static error page if the company's primary website is unavailable. The primary website's DNS records are hosted in Amazon Route 53. The domain is pointing to an Application Load Balancer (ALB). The company needs a solution that minimizes changes and infrastructure overhead.

Which solution will meet these requirements?

Options:

A.

Update the Route 53 records to use a latency routing policy. Add a static error page that is hosted in an Amazon S3bucket to the records so that the traffic is sent to the most responsive endpoints.

B.

Set up a Route 53 active-passive failover configuration. Direct traffic to a static error page that is hosted in anAmazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy.

C.

Set up a Route 53 active-active configuration with the ALB and an Amazon EC2 instance that hosts a static errorpage as endpoints. Configure Route 53 to send requests to the instance only if the health checks fail for the ALB.

D.

Update the Route 53 records to use a multivalue answer routing policy. Create a health check. Direct traffic to thewebsite if the health check passes. Direct traffic to a static error page that is hosted in Amazon S3 if the health check does not pass.

Question 147

A company has two applications: a sender application that sends messages with payloads to be processed and a processing application intended to receive the messages with payloads. The company wants to implement an AWS service to handle messages between the two applications. The sender application can send about 1.000 messages each hour. The messages may take up to 2 days to be processed. If the messages fail to process, they must be retained so that they do not impact the processing of any remaining messages.

Which solution meets these requirements and is the MOST operationally efficient?

Options:

A.

Set up an Amazon EC2 instance running a Redis database. Configure both applications to use the instance. Store, process, and delete the messages, respectively.

B.

Use an Amazon Kinesis data stream to receive the messages from the sender application. Integrate the processing application with the Kinesis Client Library (KCL).

C.

Integrate the sender and processor applications with an Amazon Simple Queue Service (Amazon SQS) queue. Configure a dead-letter queue to collect the messages that failed to process.

D.

Subscribe the processing application to an Amazon Simple Notification Service (Amazon SNS) topic to receive notifications to process. Integrate the sender application to write to the SNS topic.

Question 148

A company's web application is running on Amazon EC2 instances behind an Application Load Balancer. The company recently changed its policy, which now requires the application to be accessed from one specific country only.

Which configuration will meet this requirement?

Options:

A.

Configure the security group for the EC2 instances.

B.

Configure the security group on the Application Load Balancer.

C.

Configure AWS WAF on the Application Load Balancer in a VPC.

D.

Configure the network ACL for the subnet that contains the EC2 instances.
