질문 # 166
A development team uses AWS Lambda functions with reserved concurrency to support an application that processes data from an Amazon DynamoDB table. During peak hours, the development team observes a slowdown in the application. Some function invocations fail to run.
During less busy hours, the application runs smoothly, and all the Lambda functions run as expected.
The development team must investigate the root cause of the issue.
Which Lambda function metrics should the development team check to meet this requirement?

A. Check the Duration and UnreservedConcurrentExecutions metrics in AWS CloudTrail.
B. Check the Throttles and ConcurrentExecutions metrics in Amazon CloudWatch.
C. Check the Invocations and ProvisionedConcurrencyUtilization metrics in AWS CloudTrail.
D. Check the OversizedRecordCount and ProvisionedConcurrentExecutions metrics in Amazon CloudWatch.

정답：B

설명：
The Throttles metric indicates when Lambda invocations are rejected due to exceeding reserved concurrency, and ConcurrentExecutions shows how many executions are happening simultaneously. Monitoring these Amazon CloudWatch metrics helps identify if the function is hitting concurrency limits during peak hours, which is likely the root cause of the observed slowdowns and failures.

질문 # 167
A company uses Amazon SNS to send payment confirmation messages for completed transactions across multiple services.
The company must maintain strict data security standards. The SNS messages must not include sensitive data such as credit card information. The company wants to automatically detect and mask sensitive information before the data leaves the company's systems.
Which solution will meet these requirements?

A. Implement a custom AWS Lambda function that sanitizes messages after publication.
B. Configure Amazon SNS data protection policies to detect and redact sensitive data.
C. Route the SNS messages through an HTTPS endpoint that is configured with AWS WAF rules to block requests that contain sensitive data patterns.
D. Encrypt SNS messages with an AWS KMS key before publishing.

정답：B

설명：
Amazon SNS data protection policies can automatically inspect messages for sensitive data types and redact or block that data before messages are delivered to subscribers. This native feature enforces data security controls centrally and automatically, ensuring sensitive information such as credit card data is masked before it leaves the system without requiring custom code or additional infrastructure.

질문 # 168
A developer created an AWS Lambda function to process data in an application. The function pulls large objects from an Amazon S3 bucket, processes the data, and loads the processed data into a second S3 bucket. Application users have reported slow response times. The developer checks the logs and finds that Lambda function invocations run much slower than expected. The function itself is simple and has a small deployment package. The function initializes quickly. The developer needs to improve the performance of the application. Which solution will meet this requirement with the LEAST operational overhead?

A. Configure the function to use ephemeral storage. Upload the objects and process data in the /tmp directory.
B. Store the data in an Amazon EFS file system. Mount the file system to a local directory in the function.
C. Create an Amazon EventBridge rule to schedule invocations of the function every minute.
D. Create a Lambda layer to package the function dependencies. Add the layer to the function.

정답：A

설명：
Configuring the Lambda function to use ephemeral storage and processing data in the /tmp directory improves performance by leveraging local storage during execution.
* Why Option C is Correct:
* Ephemeral Storage: Lambda provides temporary storage (up to 10 GB) in the /tmp directory for each invocation, which is faster than pulling data directly from S3 multiple times.
* Performance Boost: Data can be downloaded to /tmp, processed locally, and uploaded to the destination S3 bucket, minimizing S3 network calls.
* Low Overhead: This approach requires only minimal changes to the function's configuration.
* Why Not Other Options:
* Option A: Using Amazon EFS adds complexity and is unnecessary for this use case.
* Option B: Scheduling the function does not address the root cause of slow performance.
* Option D: Lambda layers improve deployment efficiency, not runtime performance for this scenario.
References:
* Using Ephemeral Storage in AWS Lambda
* Best Practices for S3 and Lambda Performance

질문 # 169
A video streaming company has a pipe in Amazon EventBridge Pipes that uses an Amazon Simple Queue Service (Amazon SQS) queue as an event source. The pipe publishes all source events to a target EventBridge event bus. Before events are published, the pipe uses an AWS Lambda function to retrieve the stream status of each event from a database and adds the stream status to each source event.
The company wants the pipe to publish events to the event bus only if the video stream has a status of ready.
Which solution will meet these requirements?

A. Update the Lambda function to return only video streams that have a status of ready.
B. Add a filter step to the pipe that will match on a stream status of ready.
C. Add an input transformer to the pipe output that filters streams that have a status of ready.
D. Include a filter for a status of ready in all EventBridge rules that subscribe to the event bus.

정답：B

질문 # 170
A developer is building a web and mobile application for two types of users: regular users and guest users. Regular users are required to log in, but guest users do not log in. Users should see only their data, regardless of whether they authenticate. Users need AWS credentials before they can access AWS resources.

A. Generate temporary credentials. Store the temporary credentials in AWS Secrets Manager. Use the temporary credentials to access the required resources.
B. Use an Amazon Cognito identity pool to generate temporary AWS credentials that are linked to an unauthenticated role that has access to the required resources.
C. Set up an IAM user that has permissions to the required resources. Hardcode the IAM credentials in the web and mobile application.
D. Generate temporary keys that are stored in AWS KMS. Use the temporary keys to access the required resources.

정답：B

설명：
Comprehensive and Detailed Step-by-Step
Option A: Amazon Cognito Identity Pool with Unauthenticated Role
Cognito identity pools can generate temporary AWS credentials for both authenticated and unauthenticated users.
For guest users, Cognito assigns an unauthenticated role with limited permissions, ensuring secure access to only their resources.
This is the most secure and efficient solution for managing AWS credentials dynamically without hardcoding or storing them.
Why Other Options Are Incorrect:
Option B: Hardcoding IAM credentials in the application is insecure and violates best practices.
Option C and D: Temporary keys stored in KMS or Secrets Manager require additional implementation overhead and do not inherently manage user-specific access.
Reference:
Amazon Cognito Identity Pools
