• Question 1475:

  A company is developing a microservices-based application to manage the company's delivery operations.

  The application consists of microservices that process orders, manage a fleet of delivery vehicles, and optimize delivery routes.

  Which solution will meet these requirements with the LEAST operational overhead?

  A. Use Amazon API Gateway REST APIs to establish communication between microservices. Deploy the application on Amazon EC2 instances in Auto Scaling groups.
  B. Use Amazon Simple Queue Service (Amazon SQS) to establish communication between microservices. Deploy the application on Amazon Elastic Container Service (Amazon ECS) containers on AWS Fargate.
  C. Use WebSocket-based communication between microservices. Deploy the application on Amazon EC2 instances in Auto Scaling groups.
  D. Use Amazon Simple Notification Service (Amazon SNS) to establish communication between microservices. Deploy the application on Amazon Elastic Container Service (Amazon ECS) containers on Amazon EC2 instances.
  B. Use Amazon Simple Queue Service (Amazon SQS) to establish communication between microservices. Deploy the application on Amazon Elastic Container Service (Amazon ECS) containers on AWS Fargate.

  Explanation

  Amazon SQS is a fully managed message queuing service that reliably decouples and scales microservices, distributed systems, and serverless applications. By using SQS, microservices can communicate asynchronously, handle bursts of traffic, and avoid data loss by buffering messages until they are processed. Deploying the services on ECS with AWS Fargate further reduces operational overhead by removing the need to manage servers, allowing independent scaling of each microservice.

  " Amazon SQS decouples application components and enables message durability and scaling. AWS Fargate removes the need to manage infrastructure, supporting independent scaling and minimal operational overhead. "

• Question 1476:

  A company wants to analyze and generate reports to track the usage of its mobile app. The app is popular and has a global user base. The company uses a custom report building program to analyze application usage. The program generates multiple reports during the last week of each month. The program takes less than 10 minutes to produce each report. The company rarely uses the program to generate reports outside of the last week of each month.

  The company wants to generate reports in the least amount of time when the reports are requested.

  Which solution will meet these requirements MOST cost-effectively?

  A. Run the program by using Amazon EC2 On-Demand Instances. Create an Amazon EventBridge rule to start the EC2 instances when reports are requested. Run the EC2 instances continuously during the last week of each month.
  B. Run the program in AWS Lambda. Create an Amazon EventBridge rule to run a Lambda function when reports are requested.
  C. Run the program in Amazon Elastic Container Service (Amazon ECS). Schedule Amazon ECS to run the program when reports are requested.
  D. Run the program by using Amazon EC2 Spot Instances. Create an Amazon EventBndge rule to start the EC2 instances when reports are requested. Run the EC2 instances continuously during the last week of each month.

• Question 1478:

  A company deploys a stateful application on Amazon EC2 On-Demand Instances in multiple Availability Zones behind an Application Load Balancer (ALB). The application workload is predictable, and the company has not received any CPU usage alerts. The company expects to run the application for at least 1 year.

  The company expects CPU usage to increase by 50% during an upcoming 2-week holiday period. The company wants to optimize costs for the application for both the holiday period and normal operations.

  Which solution will meet these requirements in the MOST cost-effective way?

  A. Continue to use On-Demand Instances to handle the existing workload. Purchase additional on-demand Instances to handle the capacity requirement for the upcoming holiday period.
  B. Purchase a 12-month EC2 Instance Savings Plan to handle the existing workload. Use On-Demand Instances to handle the additional capacity requirement for the upcoming holiday period.
  C. Purchase a 12-month Compute Savings Plan to handle the existing workload. Use Spot Instances to handle the additional capacity requirement for the upcoming holiday period.
  D. Purchase a 12-month Compute Savings Plan to handle both the existing workload and the additional capacity requirement for the upcoming holiday period.
  B. Purchase a 12-month EC2 Instance Savings Plan to handle the existing workload. Use On-Demand Instances to handle the additional capacity requirement for the upcoming holiday period.

  ---

  Explanation

  The correct answer is B because the company has a predictable baseline workload that will run for at least 1 year, plus a temporary 2-week increase in demand during a holiday period. The most cost-effective approach is to use a long-term discount option for the steady-state workload and a flexible pricing model for the short-term burst capacity.

  An EC2 Instance Savings Plan is a strong fit for the existing workload because it provides cost savings for committed EC2 usage while matching a stable, predictable application footprint. Since the company is already using EC2 and the workload pattern is known, this is an efficient commitment for the baseline capacity. For the additional temporary holiday demand, On-Demand Instances are appropriate because the extra capacity is needed only for a short duration. This avoids overcommitting to capacity that will not be used after the holiday period ends.

  Option A is less cost-effective because it misses the savings opportunity for the predictable baseline workload.

  Option C is incorrect because the application is described as stateful, which makes Spot Instances a poor fit due to potential interruption.

  Option D is incorrect because purchasing a 12-month commitment for both the normal workload and the temporary holiday increase would likely result in paying for excess committed usage after the 2-week peak ends.

  AWS cost optimization guidance recommends using discounted commitment models for steady-state usage and On-Demand for short-lived, temporary spikes. Therefore, the best answer is to use an EC2 Instance Savings Plan for the baseline and On-Demand Instances for the seasonal increase.

• Question 1479:

  A company recently launched a variety of new workloads on Amazon EC2 instances in its AWS account.

  The company needs to create a strategy to access and administer the instances remotely and securely.

  The company needs to implement a repeatable process that works with native AWS services and follows the AWS Well-Architected Framework.

  Which solution will meet these requirements with the LEAST operational overhead?

  A. Use the EC2 serial console to directly access the terminal interface of each instance for administration.
  B. Attach the appropriate IAM role to each existing instance and new instance. Use AWS Systems Manager Session Manager to establish a remote SSH session.
  C. Create an administrative SSH key pair. Load the public key into each EC2 instance. Deploy a bastion host in a public subnet to provide a tunnel for administration of each instance.
  D. Establish an AWS Site-to-Site VPN connection. Instruct administrators to use their local on-premises machines to connect directly to the instances by using SSH keys across the VPN tunnel.
  B. Attach the appropriate IAM role to each existing instance and new instance. Use AWS Systems Manager Session Manager to establish a remote SSH session.
