AWS L3

An ecommerce company wants to launch a one-deal-a-day website on AWS. Each day will feature exactly one product on sale for a period of 24 hours. The company wants to be able to handle millions of requests each hour with millisecond latency during peak hours.Which solution will meet these requirements with the LEAST operational overhead?

• Use Amazon S3 to host the full website in different S3 buckets. Add Amazon CloudFront distributions. Set the S3 buckets as origins for the distributions. Store the order data in Amazon S3.

• Deploy the full website on Amazon EC2 instances that run in Auto Scaling groups across multiple Availability Zones. Add an Application Load Balancer (ALB) to distribute the website traffic. Add another ALB for the backend APIs. Store the data in Amazon RDS for MySQL.

• Migrate the full application to run in containers. Host the containers on Amazon Elastic Kubernetes Service (Amazon EKS). Use the Kubernetes Cluster Autoscaler to increase and decrease the number of pods to process bursts in traffic. Store the data in Amazon RDS for MySQL.

• Use an Amazon S3 bucket to host the website's static content. Deploy an Amazon CloudFront distribution. Set the S3 bucket as the origin. Use Amazon API Gateway and AWS Lambda functions for the backend APIs. Store the data in Amazon DynamoDB.

A company has registered its domain name with Amazon Route 53. The company uses Amazon API Gateway in the ca-central-1 Region as a public interface for its backend microservice APIs. Third-party services consume the APIs securely. The company wants to design its API Gateway URL with the company's domain name and corresponding certificate so that the third-party services can use HTTPS.Which solution will meet these requirements?

• Create stage variables in API Gateway with Name="Endpoint-URL" and Value="Company Domain Name" to overwrite the default URL. Import the public certificate associated with the company's domain name into AWS Certificate Manager (ACM).

• Create Route 53 DNS records with the company's domain name. Point the alias record to the Regional API Gateway stage endpoint. Import the public certificate associated with the company's domain name into AWS Certificate Manager (ACM) in the us-east-1 Region.

• Create a Regional API Gateway endpoint. Associate the API Gateway endpoint with the company's domain name. Import the public certificate associated with the company's domain name into AWS Certificate Manager (ACM) in the same Region. Attach the certificate to the API Gateway endpoint. Configure Route 53 to route traffic to the API Gateway endpoint.

• Create a Regional API Gateway endpoint. Associate the API Gateway endpoint with the company's domain name. Import the public certificate associated with the company's domain name into AWS Certificate Manager (ACM) in the us-east-1 Region. Attach the certificate to the API Gateway APIs. Create Route 53 DNS records with the company's domain name. Point an A record to the company's domain name.

A company is deploying a new public web application to AWS. The application will run behind an Application Load Balancer (ALB). The application needs to be encrypted at the edge with an SSL/TLS certificate that is issued by an external certificate authority (CA). The certificate must be rotated each year before the certificate expires.What should a solutions architect do to meet these requirements?

• Use AWS Certificate Manager (ACM) to issue an SSL/TLS certificate. Apply the certificate to the ALB. Use the managed renewal feature to automatically rotate the certificate.

• Use AWS Certificate Manager (ACM) to issue an SSL/TLS certificate. Import the key material from the certificate. Apply the certificate to the ALUse the managed renewal feature to automatically rotate the certificate.

• Use AWS Certificate Manager (ACM) Private Certificate Authority to issue an SSL/TLS certificate from the root CA. Apply the certificate to the ALB. Use the managed renewal feature to automatically rotate the certificate.

• Use AWS Certificate Manager (ACM) to import an SSL/TLS certificate. Apply the certificate to the ALB. Use Amazon EventBridge (Amazon CloudWatch Events) to send a notification when the certificate is nearing expiration. Rotate the certificate manually.

A company has created an image analysis application in which users can upload photos and add photo frames to their images. The users upload images and metadata to indicate which photo frames they want to add to their images. The application uses a single Amazon EC2 instance and Amazon DynamoDB to store the metadata.The application is becoming more popular, and the number of users is increasing. The company expects the number of concurrent users to vary significantly depending on the time of day and day of week. The company must ensure that the application can scale to meet the needs of the growing user base.Which solution meats these requirements?

• Use AWS Lambda to process the photos. Store the photos and metadata in DynamoDB.

• Use Amazon Kinesis Data Firehose to process the photos and to store the photos and metadata.

• Use AWS Lambda to process the photos. Store the photos in Amazon S3. Retain DynamoDB to store the metadata.

• Increase the number of EC2 instances to three. Use Provisioned IOPS SSD (io2) Amazon Elastic Block Store (Amazon EBS) volumes to store the photos and metadata.

An online gaming company hosts an application on multiple Amazon EC2 instances behind an Application Load Balancer in multiple regions. For regional law and distribution policy, they must store content based on users' region.

As a Solution Architect, what solution should you provide to meet the criteria?

• Use Amazon Route 53 with geoproximity routing policy.

• Use Amazon CloudFront with multiple origins and AWS WAF routing policy.

• Use Application Load Balancers with multi-Region routing.

• Use Amazon Route 53 with geolocation routing policy.

You have a set of Docker images that you use for building containers. You want to start using the Elastic Container Service and utilize the Docker images. You need a place to store these Docker images. Which of the following can be used for this purpose?

• Use AWS DynamoDB to store the Docker images.

• Use AWS RDS to store the Docker images.

• Use EC2 Instances with EBS Volumes to store the Docker images.

• Use the ECR Service to store the Docker images.

A company is planning to use the AWS ECS service to work with containers. There is a need for the least amount of administrative overhead while launching containers. How can this be achieved?

• Use the Fargate launch type in AWS ECS.

• Use the EC2 launch type in AWS ECS.

• Use the Auto Scaling launch type in AWS ECS.

• Use the ELB launch type in AWS ECS.

An application currently writes a large number of records to a DynamoDB table in one region. There is a requirement for a secondary application to retrieve new records written to the DynamoDB table every 2 hours and process the updates accordingly. Which of the following is an ideal way to ensure that the secondary application gets the relevant changes from the DynamoDB table?

• Insert a timestamp for each record and then scan the entire table for the timestamp asper the last 2 hours.

• Create another DynamoDB table with the records modified in the last 2 hours.

• Use DynamoDB Streams to monitor the changes in the DynamoDB table.

• Transfer records to S3 which were modified in the last 2 hours.

A company has setup an application in AWS that interacts with DynamoDB. It is required that when an item is modified in a DynamoDB table, an immediate entry is made to the associating application. How can this be accomplished? Choose 2 answers from the choices below.

• Setup CloudWatch to monitor the DynamoDB table for changes. Then trigger a Lambda function to send the changes to the application.

• Setup CloudWatch logs to monitor the DynamoDB table for changes. Then trigger AWS SQS to send the changes to the application.

• Use DynamoDB streams to monitor the changes to the DynamoDB table.

• Trigger a lambda function to make an associated entry in the application as soon as the DynamoDB streams are modified

You have been tasked with architecting an application in AWS. The architecture would consist of EC2, the Classic Load Balancer, Auto Scaling and Route 53. There is a directive to ensure that Blue-Green deployments are possible in this architecture. Which routing policy could you ideally use in Route 53 for achieving Blue-Green deployments?

• Simple

• Multi-answer

• Latency

• Weighted
