AWS Certified Solutions Architect - Professional Questions and Answers

Question 65

A company has implemented an ordering system using an event-driven architecture. During initial testing, the system stopped processing orders. Further log analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SQS) standard queue was causing an error on the backend and blocking all subsequentorder messages The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds. A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages.

Which step should the solutions architect take to meet these requirements?

Options:

A.

Increase the backend processing timeout to 30 seconds to match the visibility timeout.

B.

Reduce the visibility timeout of the queue to automatically remove the faulty message.

C.

Configure a new SQS FIFO queue as a dead-letter queue to isolate the faulty messages.

D.

Configure a new SQS standard queue as a dead-letter queue to isolate the faulty messages.

Question 66

A company provides a software as a service (SaaS) application that runs in the AWS Cloud. The application runs on Amazon EC2 instances behind a Network LoadBalancer (NLB). The instances are in an Auto Scaling group and are distributed across three Availability Zones in a single AWS Region.

The company is deploying the application into additional Regions. The company must provide static IP addresses for the application to customers so that the customers can add the IP addresses to allow lists.

The solution must automatically route customers to the Region that is geographically closest to them.

Which solution will meet these requirements?

Options:

A.

Create an Amazon CloudFront distribution. Create a CloudFront origin group. Add the NLB for each additional Region to the origin group. Provide customers with the IP address ranges of the distribution's edge locations.

B.

Create an AWS Global Accelerator standard accelerator. Create a standard accelerator endpoint for the NLB in each additional Region. Provide customers with the Global Accelerator IP address.

C.

Create an Amazon CloudFront distribution. Create a custom origin for the NLB in each additional Region. Provide customers with the IP address ranges of the distribution's edge locations.

D.

Create an AWS Global Accelerator custom routing accelerator. Create a listener for the custom routing accelerator. Add the IP address and ports for the NLB in each additional Region. Provide customers with the Global Accelerator IP address.

Question 67

A solutions architect needs to review the design of an Amazon EMR cluster that is using the EMR File System (EMRFS). The cluster performs tasks that are critical to business needs. The cluster is running Amazon EC2 On-Demand Instances at all times tor all task, primary, and core nodes. The EMR tasks run each morning, starting at 1 ;00 AM. and take 6 hours to finish running. The amount of time to complete the processing is not a priority because the data is not referenced until late in the day.

The solutions architect must review the architecture and suggest a solution to minimize the compute costs.

Which solution should the solutions architect recommend to meet these requirements?

Options:

A.

Launch all task, primary, and core nodes on Spool Instances in an instance fleet. Terminate the cluster, including all instances, when the processing is completed.

B.

Launch the primary and core nodes on On-Demand Instances. Launch the task nodes on Spot Instances in an instance fleet. Terminate the cluster, including all instances, when the processing is completed. Purchase Compute Savings Plans to cover the On-Demand Instance usage.

C.

Continue to launch all nodes on On-Demand Instances. Terminate the cluster, including all instances, when the processing is completed. Purchase Compute Savings Plans to cover the On-Demand Instance usage

D.

Launch the primary and core nodes on On-Demand Instances. Launch the task nodes on Spot Instances in an instance fleet. Terminate only the task node instances when the processing is completed. Purchase Compute Savings Plans to cover the On-Demand Instance usage.

Question 68

B.

Use App2Container on ECS EC2 with NLB and Aurora MySQL.

C.

Use Porting Assistant and EKS with Fargate and Aurora MySQL.

D.

Use Porting Assistant and EKS with Fargate and RDS SQL Server.
