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

Question 41

A company has a legacy data processing application that runs on Amazon EC2 instances. Data is processed sequentially, but the order of results does not matter. The application uses a monolithic architecture. The only way that the company can scale the application to meet increased demand is to increase the size of the instances.

The company's developers have decided to rewrite the application to use a microservices architecture on Amazon Elastic Container Service (Amazon ECS).

What should a solutions architect recommend for communication between the microservices?

Options:

A.

Create an Amazon Simple Queue Service (Amazon SQS) queue. Add code to the data producers, and send data to the queue. Add code to the data consumers to process data from the queue.

B.

Create an Amazon Simple Notification Service (Amazon SNS) topic. Add code to the data producers, and publish notifications to the topic. Add code to the data consumers to subscribe to the topic.

C.

Create an AWS Lambda function to pass messages. Add code to the data producers to call the Lambda function with a data object. Add code to the data consumers to receive a data object that is passed from the Lambda function.

D.

Create an Amazon DynamoDB table. Enable DynamoDB Streams. Add code to the data producers to insert data into the table. Add code to the data consumers to use the DynamoDB Streams API to detect new table entries and retrieve the data.

Question 42

A company runs a high performance computing (HPC) workload on AWS. The workload required low-latency network performance and high network throughput with tightly coupled node-to-node communication. The Amazon EC2 instances are properly sized for compute and storage capacity, and are launched using default options.

What should a solutions architect propose to improve the performance of the workload?

Options:

A.

Choose a cluster placement group while launching Amazon EC2 instances.

B.

Choose dedicated instance tenancy while launching Amazon EC2 instances.

C.

Choose an Elastic Inference accelerator while launching Amazon EC2 instances.

D.

Choose the required capacity reservation while launching Amazon EC2 instances.

Question 43

A company sells ringtones created from clips of popular songs. The files containing the ringtones are stored in Amazon S3 Standard and are at least 128 KB in size. The company has millions of files, but downloads are infrequent for ringtones older than 90 days. The company needs to save money on storage while keeping the most accessed files readily available for its users.

Which action should the company take to meet these requirements MOST cost-effectively?

Options:

A.

Configure S3 Standard-Infrequent Access (S3 Standard-IA) storage for the initial storage tier of the objects.

B.

Move the files to S3 Intelligent-Tiering and configure it to move objects to a less expensive storage tier after 90 days.

C.

Configure S3 inventory to manage objects and move them to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.

D.

Implement an S3 Lifecycle policy that moves the objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.

Question 44

A company runs a production application on a fleet of Amazon EC2 instances. The application reads the data from an Amazon SQS queue and processes the messages in parallel. The message volume is unpredictable and often has intermittent traffic. This application should continually process messages without any downtime.

Which solution meets these requirements MOST cost-effectively?

Options:

A.

Use Spot Instances exclusively to handle the maximum capacity required.

B.

Use Reserved Instances exclusively to handle the maximum capacity required.

C.

Use Reserved Instances for the baseline capacity and use Spot Instances to handle additional capacity.

D.

Use Reserved Instances for the baseline capacity and use On-Demand Instances to handle additional capacity.
