NEW QUESTION # 228
A company runs an application as an Amazon ECS service on an AWS Fargate cluster. The company has configured the service to use the rolling update deployment type. The company set the minimum healthy percentage to 100% and set the maximum healthy percentage to 200%.
A developer observes that a new deployment of the ECS service is failing continuously. The developer must ensure that Amazon ECS restores the most recently completed service deployment when a new service deployment fails.
Which solution will meet this requirement?
Answer: D
Explanation:
The requirement is specifically to have ECS automatically restore the last known good deployment when a new deployment fails, while the service is using the rolling update deployment type. Amazon ECS supports this through the deployment circuit breaker with the option to rollback on failures.
When enabled, the deployment circuit breaker monitors the deployment and detects failure conditions such as tasks repeatedly failing health checks, not reaching steady state, or being unable to start successfully. With rollback enabled, ECS automatically stops the failing deployment and reverts the service to the most recently completed (stable) task definition, restoring service stability without manual intervention.
Option D matches exactly: keep the rolling deployment type and enable circuit breaker + rollback. This is minimal change and directly addresses the behavior observed.
Options A and B are unrelated: service autoscaling adjusts desired count based on metrics and does not roll back failed deployments.
Option C could also achieve rollback behavior, but switching to blue/green introduces additional components (AWS CodeDeploy integration, target groups, and traffic shifting), which is unnecessary when the requirement can be met within rolling deployments.
Therefore, enabling the ECS deployment circuit breaker with rollback on failures for a rolling deployment is the correct solution.
NEW QUESTION # 229
A developer is building an application that processes a stream of user-supplied data. The data stream must be consumed by multiple Amazon EC2-based processing applications in parallel and in real time. Each processor must be able to resume without losing data if there is a service interruption. The application architect plans to add other processors in the near future and wants to minimize the amount of data duplication involved.
Which solution will satisfy these requirements?
Answer: C
Explanation:
The requirements describe a real-time streaming use case where multiple processing applications must read the same stream in parallel, each must be able to resume processing after interruptions without data loss, and the system should support adding new processors with minimal duplication. Amazon Kinesis Data Streams (KDS) is purpose-built for this pattern.
With Kinesis Data Streams, producers write records to a stream that is split into shards. Multiple consumer applications can independently read from the stream using separate consumer groups (for example, using Kinesis Client Library). Each consumer maintains its own checkpoint (sequence number position), which allows it to resume from the last processed record after a restart or failure. This directly meets the "resume without losing data" requirement.
KDS also supports a configurable retention period (commonly 24 hours by default, extendable), enabling replay and recovery without forcing producers to re-send data or duplicating messages for each processor.
Adding new consumers is straightforward: a new processor can begin reading the existing stream (from latest or from a trim horizon), which minimizes duplication compared to fan-out duplication patterns.
Why the others don't fit:
* SQS is a queue, not a stream. Multiple consumers typically compete for messages rather than all consuming the same messages independently, and duplication is required if multiple apps must process the same data.
* Kinesis Data Firehose is primarily for delivery to destinations (S3, Redshift, OpenSearch) and not designed for multiple real-time parallel consumers with replay semantics.
* EventBridge is event routing with limited replay/resume semantics compared to KDS and is not intended for high-throughput stream processing with per-consumer checkpoints.
Therefore, Amazon Kinesis Data Streams satisfies all requirements.
NEW QUESTION # 230
A company is using AWS CloudFormation to deploy a two-tier application. The application will use Amazon RDS as its backend database. The company wants a solution that will randomly generate the database password during deployment. The solution also must automatically rotate the database password without requiring changes to the application.
What is the MOST operationally efficient solution that meets these requirements'?
Answer: D
Explanation:
This solution will meet the requirements by using AWS Secrets Manager, which is a service that helps protect secrets such as database credentials by encrypting them with AWS Key Management Service (AWS KMS) and enabling automatic rotation of secrets. The developer can use an AWS Secrets Manager resource in AWS CloudFormation template, which enables creating and managing secrets as part of a CloudFormation stack.
The developer can use an AWS::SecretsManager::Secret resource type to generate and rotate the password for accessing RDS database during deployment. The developer can also specify a RotationSchedule property for the secret resource, which defines how often to rotate the secret and which Lambda function to use for rotation logic. Option A is not optimal because it will use an AWS Lambda function as a CloudFormation custom resource, which may introduce additional complexity and overhead for creating and managing a custom resource and implementing rotation logic. Option B is not optimal because it will use an AWS Systems Manager Parameter Store resource with the SecureString data type, which does not support automatic rotation of secrets. Option C is not optimal because it will use a cron daemon on the application's host to generate and rotate the password, which may incur more costs and require more maintenance for running and securing a host.
NEW QUESTION # 231
A company is building a micro services app1 cation that consists of many AWS Lambda functions. The development team wants to use AWS Serverless Application Model (AWS SAM) templates to automatically test the Lambda functions. The development team plans to test a small percentage of traffic that is directed to new updates before the team commits to a full deployment of the application.
Which combination of steps will meet these requirements in the MOST operationally efficient way? (Select TWO.)
Answer: D,E
Explanation:
Explanation
This solution will meet the requirements by using AWS Serverless Application Model (AWS SAM) templates and gradual deployments to automatically test the Lambda functions. AWS SAM templates are configuration files that define serverless applications and resources such as Lambda functions. Gradual deployments are a feature of AWS SAM that enable deploying new versions of Lambda functions incrementally, shifting traffic gradually, and performing validation tests during deployment. The developer can enable gradual deployments through AWS SAM templates by adding a DeploymentPreference property to each Lambda function resource in the template. The developer can set the deployment preference type to Canary10Percent30Minutes, which means that 10 percent of traffic will be shifted to the new version of the Lambda function for 30 minutes before shifting 100 percent of traffic. The developer can also use hooks to test the deployment, which are custom Lambda functions that run before or after traffic shifting and perform validation tests or rollback actions.

NEW QUESTION # 232
A developer is creating a video search application for a global company. The video files have an average size of 2.5 TB. The video storage system must provide instant access to the video files for the first 90 days. After the first 90 days, the video files can take more than 10 minutes to load.
Which solution will meet these requirements MOST cost-effectively?
Answer: C
