• Question 207:

  A company hosts a two-tier website that runs on Amazon EC2 instances. The website has a database that runs on Amazon RDS for MySQL. All users are required to log in I customized pages.

  The website typically experiences low traffic. Occasionally, the website experiences sudden increases in traffic and becomes unresponsive. During these increases in traffic, write load. A solutions architect must improve the website's

  availability without changing the application code.

  What should the solutions architect do to meet these requirements?

  A. Create an Amazon ElastiCache for Redis cluster. Configure the application to cache common database queries in the ElastiCache cluster.
  B. Create an Auto Scaling group. Configure Amazon CloudWatch alarms to scale the number of EC2 instances based on the percentage of CPU in use during the traffic......
  C. Create an Amazon CloudFront distribution that points to the EC2 instances as the origin.Enable caching of dynamic content, and configure a write throttle from ......database.
  D. Migrate the database to an Amazon Aurora Serverless cluster. Set the maximum Aurora capacity units (ACUs) to a value high enough to respond to the traffic incre...........instances to connect to the Aurora database.
  A. Create an Amazon ElastiCache for Redis cluster. Configure the application to cache common database queries in the ElastiCache cluster.

• Question 208:

  A company must generate sales reports at the beginning of every month. The reporting process launches 20 Amazon EC2 instances on the first of the month. The process runs for 7 days and cannot be interrupted. The company wants to minimize costs.

  Which pricing model should the company choose?

  A. Reserved Instances
  B. Spot Block Instances
  C. On-Demand Instances
  D. Scheduled Reserved Instances
  D. Scheduled Reserved Instances

  Explanation/Reference:

  Scheduled Reserved Instances

  Scheduled Reserved Instances (Scheduled Instances) enable you to purchase capacity reservations that recur on a daily, weekly, or monthly basis, with a specified start time and duration, for a one- year term. You reserve the capacity in advance, so that you know it is available when you need it. You pay for the time that the instances are scheduled, even if you do not use them. Scheduled Instances are a good choice for workloads that do not run continuously, but do run on a regular schedule. For example, you can use Scheduled Instances for an application that runs during business hours or for batch processing that runs at the end of the week. If you require a capacity reservation on a continuous basis, Reserved Instances might meet your needs and decrease costs. How Scheduled Instances Work

  Amazon EC2 sets aside pools of EC2 instances in each Availability Zone for use as Scheduled Instances. Each pool supports a specific combination of instance type, operating system, and network. To get started, you must search for an available schedule. You can search across multiple pools or a single pool. After you locate a suitable schedule, purchase it. You must launch your Scheduled Instances during their scheduled time periods, using a launch configuration that matches the following attributes of the schedule that you purchased: instance type, Availability Zone, network, and platform. When you do so, Amazon EC2 launches EC2 instances on your behalf, based on the specified launch specification. Amazon EC2 must ensure that the EC2 instances have terminated by the end of the current scheduled time period so that the capacity is available for any other Scheduled Instances it is reserved for. Therefore, Amazon EC2 terminates the EC2 instances three minutes before the end of the current scheduled time period. You can't stop or reboot Scheduled Instances, but you can terminate them manually as needed. If you terminate a Scheduled Instance before its current scheduled time period ends, you can launch it again after a few minutes. Otherwise, you must wait until the next scheduled time period. The following diagram illustrates the lifecycle of a Scheduled Instance.

• Question 209:

  A company built a food ordering application that captures user data and stores it for future analysis. The application's static front end is deployed on an Amazon EC? instance. The front-end application sends the requests to the backend

  application running on separate EC2 instance. The backend application then stores the data in Amazon RDS.

  What should a solutions architect do to decouple the architecture and make it scalable?

  A. Use Amazon S3 to serve the front-end application, which sends requests to Amazon EC2 to execute the backend application. The backend application will process and store the data in Amazon RDS
  B. Use Amazon S3 to serve the front-end application and write requests to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe Amazon EC2 instances to the HTTP/HTTPS endpoint o( the topic, and process and store the data in Amazon RDS
  C. Use an EC2 instance lo serve the front end and write requests to an Amazon SQS queue Place the backend Instance in an Auto Scaling group, and scale based on the queue depth to process and store the data in Amazon RDS.
  D. Use Amazon S3 to serve the static front-end application and send requests lo Amazon API Gateway which writes the requests to an Amazon SQS queue Place the backend instances in an Auto Scaling group, and scale based on the queue depth to process and store the data in Amazon RDS
  D. Use Amazon S3 to serve the static front-end application and send requests lo Amazon API Gateway which writes the requests to an Amazon SQS queue Place the backend instances in an Auto Scaling group, and scale based on the queue depth to process and store the data in Amazon RDS

• Question 210:

  A company has hundreds of Amazon EC2 Linux-based instances in the AWS Cloud. Systems administrators have used shared SSH keys to manage the instances After a recent audit, the company's security team is mandating the removal of all shared keys. A solutions architect must design a solution that provides secure access to the EC2 instances.

  Which solution will meet this requirement with the LEAST amount of administrative overhead?

  A. Use AWS Systems Manager Session Manager to connect to the EC2 instances.
  B. Use AWS Security Token Service (AWS STS) to generate one-time SSH keys on demand.
  C. Allow shared SSH access to a set of bastion instances. Configure all other instances to allow only SSH access from the bastion instances
  D. Use an Amazon Cognito custom authorizer to authenticate users. Invoke an AWS Lambda function to generate a temporary SSH key.
  B. Use AWS Security Token Service (AWS STS) to generate one-time SSH keys on demand.
