Amazon AWS Certified Developer - Associate Sample Questions (Q24-Q29):

NEW QUESTION # 24
A financial company must store original customer records for 10 years for legal reasons. A complete record contains personally identifiable information (PII). According to local regulations, PII is available to only certain people in the company and must not be shared with third parties. The company needs to make the records available to third-party organizations for statistical analysis without sharing the PII.
A developer wants to store the original immutable record in Amazon S3. Depending on who accesses the S3 document, the document should be returned as is or with all the PII removed. The developer has written an AWS Lambda function to remove the PII from the document. The function is named removePii.
What should the developer do so that the company can meet the PII requirements while maintaining only one copy of the document?

  • A. Set up an S3 event notification that invokes the removePii function when an S3 GET request is made. Call Amazon S3 by using a GET request to access the object without PII.
  • B. Create an S3 Object Lambda access point from the S3 console. Select the removePii function. Use S3 Access Points to access the object without PII.
  • C. Set up an S3 event notification that invokes the removePii function when an S3 PUT request is made. Call Amazon S3 by using a PUT request to access the object without PII.
  • D. Create an S3 access point from the S3 console. Use the access point name to call the GetObjectLegalHold S3 API function. Pass in the removePii function name to access the object without PII.

Answer: B

Explanation:
S3 Object Lambda allows you to add your own code to process data retrieved from S3 before returning it to an application. You can use an AWS Lambda function to modify the data, such as removing PII, redacting confidential information, or resizing images. You can create an S3 Object Lambda access point and associate it with your Lambda function. Then, you can use the access point to request objects from S3 and get the modified data back. This way, you can maintain only one copy of the original document in S3 and apply different transformations depending on who accesses it. Reference: Using AWS Lambda with Amazon S3


NEW QUESTION # 25
A company's developer has deployed an application in AWS by using AWS CloudFormation. The CloudFormation stack includes parameters in AWS Systems Manager Parameter Store that the application uses as configuration settings. The application can modify the parameter values.
When the developer updated the stack to create additional resources with tags, the developer noted that the parameter values were reset and that the values ignored the latest changes made by the application. The developer needs to change the way the company deploys the CloudFormation stack. The developer also needs to avoid resetting the parameter values outside the stack.
Which solution will meet these requirements with the LEAST development effort?

  • A. Create an Amazon RDS DB instance as a resource in the CloudFormation stack. Create a table in the database for parameter configuration. Migrate the parameters that the application is modifying from Parameter Store to the configuration table.
  • B. Create an Amazon DynamoDB table as a resource in the CloudFormation stack to hold configuration data for the application. Migrate the parameters that the application is modifying from Parameter Store to the DynamoDB table.
  • C. Modify the CloudFormation stack to set the deletion policy to Retain for the Parameter Store parameters.
  • D. Modify the CloudFormation stack policy to deny updates on Parameter Store parameters.

Answer: A


NEW QUESTION # 26
A developer is creating an application that must transfer expired items from Amazon DynamoDB to Amazon S3. The developer sets up the DynamoDB table to automatically delete items after a specific TTL. The application must process the items in DynamoDB and then must store the expired items in Amazon S3. The entire process, including item processing and storage in Amazon S3, will take 5 minutes.
Which solution will meet these requirements with the LEAST operational overhead?

  • A. Configure DynamoDB Streams to invoke an AWS Lambda function. Program the Lambda function to process the items and to store the expired items in Amazon S3.
  • B. Configure DynamoDB Accelerator (DAX) lo query for expired items based on the TTL Save the results to Amazon S3.
  • C. Create an Amazon EventBridge rule to invoke an AWS Lambda function. Program the Lambda function to process The items and to store the expired items in Amazon S3.
  • D. Deploy a custom application on an Amazon Elastic Container Service (Amazon ECS) cluster on Amazon EC2 instances. Program the custom application to process the items and to store the expired items in Amazon S3.

Answer: A


NEW QUESTION # 27
A company deploys a new application to AWS. The company is streaming application logs to Amazon CloudWatch Logs. The company's development team must receive notification by email when the word
"ERROR" appears in any log lines. A developer sets up an Amazon SNS topic and subscribes the development team to the topic.
What should the developer do next to meet the requirements?

  • A. Select the appropriate log group. Create an SNS subscription filter with "ERROR" as the filter pattern.
    Select the SNS topic as the destination.
  • B. Select the appropriate log group. Create a CloudWatch metric filter with "ERROR" as the search term.
    Create an alarm on this metric that notifies the SNS topic when the metric is 1 or higher.
  • C. In CloudWatch Logs Insights, select the appropriate log group. Create a metric query to search for the term "ERROR" in the logs. Create an alarm on this metric that notifies the SNS topic when the metric is
    1 or higher.
  • D. Create a CloudWatch alarm that includes "ERROR" as a filter pattern, a log group dimension that defines the appropriate log group, and a destination that notifies the SNS topic.

Answer: B

Explanation:
Comprehensive Detailed Explanation with all AWS References
* Why Option A is Correct:Creating a CloudWatch metric filter with "ERROR" as the search term ensures that occurrences of the word "ERROR" in logs are counted. An alarm can then be set to notify the SNS topic when the count exceeds 1. This is the standard approach to monitor specific patterns in CloudWatch Logs.
* Why Other Options are Incorrect:
* Option B: CloudWatch Logs Insights is used for querying logs manually and does not integrate directly with alarms for automated notifications.
* Option C: SNS subscription filters are not a feature for filtering log patterns in CloudWatch Logs.
* Option D: CloudWatch alarms do not directly include log filter patterns; a metric filter is needed to create the metric first.
* AWS Documentation References:
* Creating CloudWatch Metric Filters


NEW QUESTION # 28
A developer wants to insert a record into an Amazon DynamoDB table as soon as a new file is added to an Amazon S3 bucket.
Which set of steps would be necessary to achieve this?

  • A. Create an AWS Lambda function that will poll the S3 bucket and then insert the records into DynamoDB.
  • B. Create an event with Amazon EventBridge that will monitor the S3 bucket and then insert the records into DynamoDB.
  • C. Configure an S3 event to invoke an AWS Lambda function that inserts records into DynamoDB.
  • D. Create a cron job that will run at a scheduled time and insert the records into DynamoDB.

Answer: C

Explanation:
Explanation
Amazon S3 is a service that provides highly scalable, durable, and secure object storage. Amazon DynamoDB is a fully managed NoSQL database service that provides fast and consistent performance with seamless scalability. AWS Lambda is a service that lets developers run code without provisioning or managing servers.
The developer can configure an S3 event to invoke a Lambda function that inserts records into DynamoDB whenever a new file is added to the S3 bucket. This solution will meet the requirement of inserting a record into DynamoDB as soon as a new file is added to S3.
