NEW QUESTION # 441
A retail company runs a business-critical web service on an Amazon Elastic Container Service (Amazon ECS) cluster that runs on Amazon EC2 instances. The web service receives POST requests from end users and writes data to a MySQL database that runs on a separate EC2 instance. The company needs to ensure that data loss does not occur.
The current code deployment process includes manual updates of the ECS service. During a recent deployment, end users encountered intermittent 502 Bad Gateway errors in response to valid web requests.
The company wants to implement a reliable solution to prevent this issue from recurring. The company also wants to automate code deployments. The solution must be highly available and must optimize cost-effectiveness.
Which combination of steps will meet these requirements? (Choose three.)

A. Migrate the MySQL database to run on an Amazon RDS for MySQL Multi-AZ DB instance that uses Provisioned IOPS SSD (io2) storage.
B. Configure an Amazon Simple Queue Service (Amazon SQS) queue. Install the SQS agent on the containers that run in the ECS cluster to poll the queue. Write the data to the database.
C. Run the web service on an ECS cluster that has a Fargate launch type. Use AWS CodePipeline and AWS CodeDeploy to perform a blue/green deployment with validation testing to update the ECS service.
D. Migrate the MySQL database to run on an Amazon RDS for MySQL Multi-AZ DB instance that uses General Purpose SSD (gp3) storage.
E. Run the web service on an ECS cluster that has a Fargate launch type. Use AWS CodePipeline and AWS CodeDeploy to perform a canary deployment to update the ECS service.
F. Configure an Amazon Simple Queue Service (Amazon SQS) queue as an event source to receive the POST requests from the web service. Configure an AWS Lambda function to poll the queue. Write the data to the database.

Answer: A,D,E

NEW QUESTION # 442
A retail company has an on-premises data center in Europe. The company also has a multi-Region AWS presence that includes the eu-west-1 and us-east-1 Regions. The company wants to be able to route network traffic from its on-premises infrastructure into VPCs in either of those Regions. The company also needs to support traffic that is routed directly between VPCs in those Regions. No single points of failure can exist on the network.
The company already has created two 1 Gbps AWS Direct Connect connections from its on-premises data center. Each connection goes into a separate Direct Connect location in Europe for high availability. These two locations are named DX-A and DX-B, respectively. Each Region has a single AWS Transit Gateway that is configured to route all inter-VPC traffic within that Region.
Which solution will meet these requirements?

A. Create a transit VIF from the DX-A connection into a Direct Connect gateway. Create a transit VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with this Direct Connect gateway. Configure the Direct Connect gateway to route traffic between the transit gateways.
B. Create a private VIF from the DX-A connection into a Direct Connect gateway. Create a private VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with the Direct Connect gateway. Peer the transit gateways with each other to support cross-Region routing.
C. Create a transit VIF from the DX-A connection into a Direct Connect gateway. Associate the eu-west-1 transit gateway with this Direct Connect gateway. Create a transit VIF from the DX-B connection into a separate Direct Connect gateway. Associate the us-east-1 transit gateway with this separate Direct Connect gateway. Peer the Direct Connect gateways with each other to support high availability and cross-Region routing.
D. Create a transit VIF from the DX-A connection into a Direct Connect gateway. Create a transit VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with this Direct Connect gateway. Peer the transit gateways with each other to support cross-Region routing.

Answer: C

Explanation:
This solution will meet the requirements for routing network traffic from the on-premises infrastructure into VPCs in either of the eu-west-1 and us-east-1 regions and support traffic that is routed directly between VPCs in those regions.
In this solution, create a transit VIF from the DX-A connection into a Direct Connect gateway and associate the eu-west-1 transit gateway with this Direct Connect gateway. Create a transit VIF from the DX-B connection into a separate Direct Connect gateway and associate the us-east-1 transit gateway with this separate Direct Connect gateway. By peering the Direct Connect gateways with each other, it will support high availability and cross-Region routing.
Option A, C and D are not correct because they associate both the eu-west-1 and us-east-1 transit gateways with the same Direct Connect gateway which would not provide failover capabilities in case of any issue with the Direct Connect gateway.

AWS Transit Gateway

NEW QUESTION # 443
A utility company collects usage data from smart meters every 5 minutes. Data is sent to API Gateway, processed by Lambda, and stored in DynamoDB. As usage increased, Lambda durations increased and DynamoDB PUTs failed with ProvisionedThroughputExceededException. Lambda also experiences TooManyRequestsException errors.
Which combination of changes will resolve these issues? (Select TWO.)

A. Increase the payload size from the smart meters.
B. Stream the data into an Amazon Kinesis data stream from API Gateway and process the data in batches.
C. Increase the write capacity units to the DynamoDB table.
D. Collect data in an Amazon SQS FIFO queue, which triggers a Lambda function to process each message.
E. Increase the memory available to the Lambda functions.

Answer: B,C

Explanation:
Comprehensive and Detailed in Depth
A is correct because write throttling on DynamoDB means WCU (write capacity units) are insufficient. Increasing them will reduce the error rate.
D is correct because introducing Kinesis allows for efficient, high-throughput ingestion and batch processing, reducing the number of Lambda invocations and overall load.

NEW QUESTION # 444
A company has a complex web application that leverages Amazon CloudFront for global scalability and performance. Over time, users report that the web application is slowing down.
The company's operations team reports that the CloudFront cache hit ratio has been dropping steadily. The cache metrics report indicates that query strings on some URLs are inconsistently ordered and are specified sometimes in mixed-case letters and sometimes in lowercase letters.
Which set of actions should the solutions architect take to increase the cache hit ratio as quickly as possible?

A. Deploy a Lambda@Edge function to sort parameters by name and force them to be lowercase. Select the CloudFront viewer request trigger to invoke the function.
B. Deploy a reverse proxy after the load balancer to post-process the emitted URLs in the application to force the URL strings to be lowercase.
C. Update the CloudFront distribution to disable caching based on query string parameters.
D. Update the CloudFront distribution to specify casing-insensitive query string processing.

Answer: A

Explanation:
https://docs.amazonaws.cn/en_us/AmazonCloudFront/latest/DeveloperGuide/lambda-examples.html#lambda-examples-query-string-examples Before CloudFront serves content from the cache it will trigger any Lambda function associated with the Viewer Request, in which we can normalize parameters.
