NEW QUESTION # 193
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,E

Explanation:
Requirement Summary:
EKS containers send logs to CloudWatch Logs
Need to process logs in real time
Trigger logic based on a specific error in logs
Evaluate Options:
Option A: SNS topic with filter policy
SNS filter policies work on message attributes, not on CloudWatch Logs subscription filters Option B: Subscription filter on log group This enables real-time log processing You can create a subscription filter with a pattern matching specific error strings Sends matched logs to a Lambda function or Kinesis Option C: CloudWatch agent operator for trace collection Irrelevant for log processing Used for monitoring and tracing, not real-time log filtering Option D: Lambda function to process logs Once logs match the pattern, Lambda can process and act (e.g., alert, store, analyze) Option E: EventBridge rule on a schedule Not real-time Scheduled EventBridge rules are for cron-like tasks, not log stream processing Subscription filters: https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/SubscriptionFilters.html Real-time log processing with Lambda: https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs

NEW QUESTION # 195
A developer needs to export the contents of several Amazon DynamoDB tables into Amazon S3 buckets to comply with company data regulations. The developer uses the AWS CLI to run commands to export from each table to the proper S3 bucket. The developer sets up AWS credentials correctly and grants resources appropriate permissions. However, the exports of some tables fail.
What should the developer do to resolve this issue?

Answer: C

Explanation:
Comprehensive Detailed and Lengthy Step-by-Step Explanation with All AWS Developer References:
1. Understanding the Use Case:
The developer needs to export DynamoDB table data into Amazon S3 buckets using the AWS CLI, and some exports are failing. Proper credentials and permissions have already been configured.
2. Key Conditions to Check:
* Region Consistency:DynamoDB exports require that the target S3 bucket and the DynamoDB table reside in the same AWS Region. If they are not in the same Region, the export process will fail.
* Point-in-Time Recovery (PITR):PITR is not required for exporting data from DynamoDB to S3.
Enabling PITR allows recovery of table states at specific points in time but does not directly influence export functionality.
* DynamoDB Streams:Streams allow real-time capture of data modifications but are unrelated to the bulk export feature.
* DAX (DynamoDB Accelerator):DAX is a caching service that speeds up read operations for DynamoDB but does not affect the export functionality.
3. Explanation of the Options:
* Option A:"Ensure that point-in-time recovery is enabled on the DynamoDB tables."While PITR is useful for disaster recovery and restoring table states, it is not required for exporting data to S3. This option does not address the export failure.
* Option B:"Ensure that the target S3 bucket is in the same AWS Region as the DynamoDB table."This is the correct answer. DynamoDB export functionality requires the target S3 bucket to reside in the same AWS Region as the DynamoDB table. If the S3 bucket is in a different Region, the export will fail.
* Option C:"Ensure that DynamoDB streaming is enabled for the tables."Streams are useful for capturing real-time changes in DynamoDB tables but are unrelated to the export functionality. This option does not resolve the issue.
* Option D:"Ensure that DynamoDB Accelerator (DAX) is enabled."DAX accelerates read operations but does not influence the export functionality. This option is irrelevant to the issue.
4. Resolution Steps:
To ensure successful exports:
* Verify the Region of the DynamoDB tables:
* Check the Region where each table is located.
* Verify the Region of the target S3 buckets:
* Confirm that the target S3 bucket for each export is in the same Region as the corresponding DynamoDB table.
* If necessary, create new S3 buckets in the appropriate Regions.
* Run the export command again with the correct setup:
aws dynamodb export-table-to-point-in-time
--table-name <TableName>
--s3-bucket <BucketName>
--s3-prefix <Prefix>
--export-time <ExportTime>
--region <Region>

* Exporting DynamoDB Data to Amazon S3
* S3 Bucket Region Requirements for DynamoDB Exports
* AWS CLI Reference for DynamoDB Export


NEW QUESTION # 196
A developer is building an event-driven application by using AWS Lambda and Amazon EventBridge. The Lambda function needs to push events to an EventBridge event bus. The developer uses an SDK to run the PutEvents EventBridge action and specifies no credentials in the code. After deploying the Lambda function, the developer notices that the function is failing and there are AccessDeniedException errors in the logs.
How should the developer resolve this issue?

Answer: A

A developer is creating a publicly accessible enterprise website consisting of only static assets.
The developer is hosting the website in Amazon S3 and serving the website to users through an Amazon CloudFront distribution.
