1. Question 941 · 1017 in bank

   A company runs an on-premises application that is powered by a MySQL database. The company is migrating the application to AWS to increase the application's elasticity and availability. The current architecture shows heavy read activity on the database during times of normal operation. Every 4 hours, the company's development team pulls a full export of the production database to populate a database in the staging environment. During this period, users experience unacceptable application latency. The development team is unable to use the staging environment until the procedure completes. A solutions architect must recommend replacement architecture that alleviates the application latency issue. The replacement architecture also must give the development team the ability to continue using the staging environment without delay. Which solution meets these requirements?

   • AUse Amazon Aurora MySQL with Multi-AZ Aurora Replicas for production. Populate the staging database by implementing a backup and restore process that uses the mysqldump utility.
   • BUse Amazon Aurora MySQL with Multi-AZ Aurora Replicas for production. Use database cloning to create the staging database on-demand.
   • CUse Amazon RDS for MySQL with a Multi-AZ deployment and read replicas for production. Use the standby instance for the staging database.
   • DUse Amazon RDS for MySQL with a Multi-AZ deployment and read replicas for production. Populate the staging database by implementing a backup and restore process that uses the mysqldump utility.

   Show answer

   Answer: B

   Explanation

   The recommended solution is Option B: Use Amazon Aurora MySQL with Multi-AZ Aurora Replicas for production. Use database cloning to create the staging database on-demand. To alleviate the application latency issue, the recommended solution is to use Amazon Aurora MySQL with Multi-AZ Aurora Replicas for production, and use database cloning to create the staging database on-demand. This allows the development team to continue using the staging environment without delay, while also providing elasticity and availability for the production application. Therefore, Options A, C, and D are not recommended

2. Question 942 · 1017 in bank

   A company has an employee web portal. Employees log in to the portal to view payroll details. The company is developing a new system to give employees the ability to upload scanned documents for reimbursement. The company runs a program to extract text-based data from the documents and attach the extracted information to each employee’s reimbursement IDs for processing. The employee web portal requires 100% uptime. The document extract program runs infrequently throughout the day on an on-demand basis. The company wants to build a scalable and cost-effective new system that will require minimal changes to the existing web portal. The company does not want to make any code changes. Which solution will meet these requirements with the LEAST implementation effort?

   • ARun Amazon EC2 On-Demand Instances in an Auto Scaling group for the web portal. Use an AWS Lambda function to run the document extract program. Invoke the Lambda function when an employee uploads a new reimbursement document.
   • BRun Amazon EC2 Spot Instances in an Auto Scaling group for the web portal. Run the document extract program on EC2 Spot Instances. Start document extract program instances when an employee uploads a new reimbursement document.
   • CPurchase a Savings Plan to run the web portal and the document extract program. Run the web portal and the document extract program in an Auto Scaling group.
   • DCreate an Amazon S3 bucket to host the web portal. Use Amazon API Gateway and an AWS Lambda function for the existing functionalities. Use the Lambda function to run the document extract program. Invoke the Lambda function when the API that is associated with a new document upload is called.

   Show answer

   Answer: A

   Explanation

   Answer: A This solution offers the most scalable and cost-effective approach with minimal changes to the existing web portal and no code modifications. Why Not Other Options?: Option B (Spot Instances): Spot Instances are not suitable for workloads requiring 100% uptime, as they can be terminated by AWS with short notice. Option C (Savings Plan): A Savings Plan could reduce costs but does not address the requirement for running the document extraction program efficiently or without code changes. Option D (S3 with API Gateway and Lambda): This would require significant changes to the existing web portal setup, including moving the portal to S3 and reconfiguring its architecture, which contradicts the requirement of minimal implementation effort and no code change.

   A media company has a multi-account AWS environment in the us-east-1 Region. The company has an Amazon Simple Notification Service (Amazon SNS) topic in a production account that publishes performance metrics. The company has an AWS Lambda function in an administrator account to process and analyze log data. The Lambda function that is in the administrator account must be invoked by messages from the SNS topic that is in the production account when significant metrics are reported. Which combination of steps will meet these requirements? (Choose two.)

   • ACreate an IAM resource policy for the Lambda function that allows Amazon SNS to invoke the function.
   • BImplement an Amazon Simple Queue Service (Amazon SQS) queue in the administrator account to buffer messages from the SNS topic that is in the production account. Configure the SQS queue to invoke the Lambda function.
   • CCreate an IAM policy for the SNS topic that allows the Lambda function to subscribe to the topic.
   • DUse an Amazon EventBridge rule in the production account to capture the SNS topic notifications. Configure the EventBridge rule to forward notifications to the Lambda function that is in the administrator account.
   • EStore performance metrics in an Amazon S3 bucket in the production account. Use Amazon Athena to analyze the metrics from the administrator account.

4. Question 944 · 1017 in bank

   A company is migrating an application from an on-premises location to Amazon Elastic Kubernetes Service (Amazon EKS). The company must use a custom subnet for pods that are in the company's VPC to comply with requirements. The company also needs to ensure that the pods can communicate securely within the pods' VPC. Which solution will meet these requirements?

   • AConfigure AWS Transit Gateway to directly manage custom subnet configurations for the pods in Amazon EKS.
   • BCreate an AWS Direct Connect connection from the company's on-premises IP address ranges to the EKS pods.
   • CUse the Amazon VPC CNI plugin for Kubernetes. Define custom subnets in the VPC cluster for the pods to use.
   • DImplement a Kubernetes network policy that has pod anti-affinity rules to restrict pod placement to specific nodes that are within custom subnets.

   Show answer

   Answer: C

   Explanation

   The Amazon VPC Container Network Interface (CNI) plugin is the default network plugin for Amazon EKS. It allows Kubernetes pods to receive IP addresses from a VPC's subnet and enables pods to communicate securely within the VPC as if they were native VPC resources.
