NEW QUESTION # 85
A developer uses AWS CloudFormation to deploy an Amazon API Gateway API and an AWS Step Functions state machine The state machine must reference the API Gateway API after the CloudFormation template is deployed The developer needs a solution that uses the state machine to reference the API Gateway endpoint.
Which solution will meet these requirements MOST cost-effectively?
Answer: D
Explanation:
the resource.
Explanation:
CloudFormation and Dynamic Reference: The DefinitionSubstitutions property in CloudFormation allows you to pass values into Step Functions state machines at runtime.
Cost-Effectiveness: This solution is cost-effective as it leverages CloudFormation's built-in capabilities, avoiding the need for additional services like Secrets Manager or AppConfig.

NEW QUESTION # 86
A developer has written the following IAM policy to provide access to an Amazon S3 bucket:
Which access does the policy allow regarding the s3:GetObject and s3:PutObject actions?
Answer: B
Explanation:
Explanation
The IAM policy shown in the image is a resource-based policy that grants or denies access to an S3 bucket based on certain conditions. The first statement allows access to any S3 action on any object in the
"DOC-EXAMPLE-BUCKET" bucket when the request is made over HTTPS (the value of aws:SecureTransport is true). The second statement denies access to the s3:GetObject and s3:PutObject actions on any object in the "DOC-EXAMPLE-BUCKET/secrets" prefix when the request is made over HTTP (the value of aws:SecureTransport is false). Therefore, the policy allows access on all objects in the
"DOC-EXAMPLE-BUCKET" bucket except on objects that start with "secrets". Reference: Using IAM policies for Amazon S3
NEW QUESTION # 87
A company runs applications on Amazon EKS containers. The company sends application logs from the containers to an Amazon CloudWatch Logs log group. The company needs to process log data in real time based on a specific error in the application logs. Which combination of steps will meet these requirements?
(Select TWO.)
Answer: B,C
Explanation:
Requirement Summary:
* EKS containers sendlogs to CloudWatch Logs
* Need toprocess logs in real time
* Trigger logic based on aspecific errorin logs
Evaluate Options:
Option A: SNS topic with filter policy
* #SNS filter policies work onmessage attributes, not onCloudWatch Logs subscription filters Option B: Subscription filter on log group
* #This enablesreal-time log processing
* You can create asubscription filterwith apattern matching specific error strings
* Sends matched logs to aLambda functionorKinesis
Option C: CloudWatch agent operator for trace collection
* #Irrelevant for log processing
* Used formonitoring and tracing, notreal-time log filtering
Option D: Lambda function to process logs
* #Once logs match the pattern, Lambda canprocess and act(e.g., alert, store, analyze) Option E: EventBridge rule on a schedule
* #Not real-time
* Scheduled EventBridge rules are forcron-like tasks, not log stream processing
* Subscription filters:https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/SubscriptionFilters.

* Real-time log processing with Lambda:https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs

NEW QUESTION # 88
A developer is working on a Python application that runs on Amazon EC2 instances. The developer wants to enable tracing of application requests to debug performance issues in the code.
Which combination of actions should the developer take to achieve this goal? (Select TWO)
Answer: A,D
Explanation:
This solution will meet the requirements by using AWS X-Ray to enable tracing of application requests to debug performance issues in the code. AWS X-Ray is a service that collects data about requests that the applications serve, and provides tools to view, filter, and gain insights into that data. The developer can install the AWS X-Ray daemon on the EC2 instances, which is a software that listens for traffic on UDP port 2000, gathers raw segment data, and relays it to the X-Ray API. The developer can also install and configure the AWS X-Ray SDK for Python in the application, which is a library that enables instrumenting Python code to generate and send trace data to the X-Ray daemon. Option A is not optimal because it will install the Amazon CloudWatch agent on the EC2 instances, which is a software that collects metrics and logs from EC2 instances and on-premises servers, not application performance data. Option C is not optimal because it will configure the application to write JSON-formatted logs to /var/log/cloudwatch, which is not a valid path or destination for CloudWatch logs. Option D is not optimal because it will configure the application to write trace data to /var/log/xray, which is also not a valid path or destination for X-Ray trace data.
