High-Performing Architecture I

Question 49

A company has an internal application hosted on EC2 instances. The application allows its employees to upload images. The uploaded images are resized to standard size and stored in S3. Employees are complaining about the slow uploading experience on the application.

The company is looking to reduce the coupling within the application and improve the overall perfomance of the application. As a solutions architect, provide the most operationally efficient image-uploading process.

What solution should a solutions architect implement to meet these requirements? (Select two options.)

A. Configure the application to save the images directly in S3 Glacier Deep Archive.

B. Configure the application to save the images directly in S3 Standard.

C. Configure the S3 event notification to invoke the Lambda function when an image is uploaded. Resized the image using the Lambda function.

D. Configure a CloudWatch Event to invoke the Lambda function when an image is uploaded to the S3 bucket. Resized the image using the lambda function.

E. Configure the application to save the images directly in S3 Glacier Instant Retrieval.

Question 50

A stock market company has a web application. The company hosts the database on the Amazon RDS for MySQL with a primary DB instance and three read replicas. Read replicas are to support the scaling needs, and their lag must not be more than 1 second behind the primary DB instance.

Read replicas experience additional lag during peak hours as the load increases to the application. As a solution architect, reduce the replication lag. The solutions architect must minimize the application change and operational overhead.

Which solution will meet the requirement?

A. Migrate the data to Amazon Aurora MySQL and replace read replicas with Aurora Replicas. Configure Aurora Auto Scaling to handle future scaling needs.

B. Configure an Application Load Balancer to forward requests to the Amazon RDS primary instance and increase the number of read replicas to five to manage more requests during scaling.

C. Configure an Amazon ElasticCache for the Redis cluster in front of the RDS instance. Modify the application to check the cache before querying the database.

D. Configure MySQL database on large EC2 instances in the Auto Scaling group and migrate the data to instances. Use the Application Load Balancer as the single entry point to the databases.

Question 51

A company runs multiple Windows-based EC2 instances on AWS. The company’s employees use SMB to share files between instances and maintain duplicate copies. The company plans to provide a highly available and durable storage solution that maintains how the files are accessed.

Which solution will meet these requirements?

A. Migrate the files to S3 and use IAM roles to access the bucket.

B. Set up an Amazon S3 File Gateway and mount the existing EC2 instances.

C. Configure an Amazon Elastic File System (EFS) with Multi-AZ configuration and migrate the files to EFS.

D. Configure an Amazon FSx for Window File Server with Multi-AZ configuration and migrate the files to FSx.

Question 52

A social media company wants to analyze the clickstream data of its application. The company plans to design a platform to analyze more than 30 TB of clickstream data daily.

As a solutions architect, which solution will meet these requirements?

A. Configure an AWS Data Pipeline to transfer data to an S3 bucket and run an Amazon EMR cluster for analytics.

B. Configure an EC2 instance in an Auto Scaling group to process and send data to S3 and use Amazon Redshift for analysis.

C. Configure Amazon Kinesis Data Streams and use Amazon Kinesis Firehose to transmit data to S3. Use Amazon Redshift for analysis.

D. Configure Amazon Kinesis Data Streams and use Amazon Kinesis Firehose to transmit data to S3. Use AWS Lambda for analysis.
