Question #262
A company sells ringtones created from clips of popular songs. The files containing the ringtones are stored in Amazon S3 Standard and are at least 128 KB in size. The company has millions of files, but downloads are infrequent for ringtones older than 90 days. The company needs to save money on storage while keeping the most accessed files readily available for its users.
Which action should the company take to meet these requirements MOST cost-effectively?
- A . Configure S3 Standard-Infrequent Access (S3 Standard-IA) storage for the initial storage tier of the objects.
- B . Move the files to S3 Intelligent-Tiering and configure it to move objects to a less expensive storage tier after 90 days.
- C . Configure S3 inventory to manage objects and move them to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.
- D . Implement an S3 Lifecycle policy that moves the objects from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-1A) after 90 days.
Correct Answer: D
D
Explanation:
This solution meets the requirements of saving money on storage while keeping the most accessed files readily available for the users. S3 Lifecycle policy can automatically move objects from one storage class to another based on predefined rules. S3 Standard-IA is a lower-cost storage class for data that is accessed less frequently, but requires rapid access when needed. It is suitable for ringtones older than 90 days that are downloaded infrequently.
Option A is incorrect because configuring S3 Standard-IA for the initial storage tier of the objects can incur higher costs for frequent access and retrieval fees.
Option B is incorrect because moving the files to S3 Intelligent-Tiering can incur additional monitoring and automation fees that may not be necessary for ringtones older than 90 days.
Option C is incorrect because using S3 inventory to manage objects and move them to S3 Standard-IA can be complex and time-consuming, and it does not provide automatic cost savings.

Question #266
A company has a mobile app for customers. The app’s data is sensitive and must be encrypted at rest. The company uses AWS Key Management Service (AWS KMS)
The company needs a solution that prevents the accidental deletion of KMS keys. The solution must use Amazon Simple Notification Service (Amazon SNS) to send an email notification to administrators when a user attempts to delete a KMS key
Which solution will meet these requirements with the LEAST operational overhead”
- A . Create an Amazon EventBndge rule that reacts when a user tries to delete a KMS key Configure an AWS Config rule that cancels any deletion of a KMS key Add the AWS Config rule as a target of the EventBridge rule Create an SNS topic that notifies the administrators
- B . Create an AWS Lambda function that has custom logic to prevent KMS key deletion Create an Amazon CloudWatch alarm that is activated when a user tries to delete a KMS key Create an Amazon EventBridge rule that invokes the Lambda function when the DeleteKey operation is performed Create an SNS topic Configure the EventBndge rule to publish an SNS message that notifies the administrators
- C . Create an Amazon EventBndge rule that reacts when the KMS DeleteKey operation is performed Configure the rule to initiate an AWS Systems Manager Automationrunbook Configure the runbook to cancel the deletion of the KMS key Create an SNS topic Configure the EventBndge rule to publish an SNS message that notifies the administrators.
- D . Create an AWS CloudTrail trail Configure the trail to delrver logs to a new Amazon CloudWatch log group Create a CloudWatch alarm based on the metric filter for the CloudWatch log group Configure the alarm to use Amazon SNS to notify the administrators when the KMS DeleteKey operation is performed
Correct Answer: C
C
Explanation:
This solution meets the requirements with the least operational overhead because it uses AWS services that are fully managed and scalable. The EventBridge rule can detect the DeleteKey operation from the AWS KMS API and trigger the Systems Manager Automation runbook, which can execute a predefined workflow to cancel the key deletion. The EventBridge rule can also publish an SNS message to the topic that sends an email notification to the administrators. This way, the company can prevent the accidental deletion of KMS keys and notify the administrators of any attempts to delete them.
Option A is not a valid solution because AWS Config rules are used to evaluate the configuration of AWS resources, not to cancel the deletion of KMS keys.
Option B is not a valid solution because it requires creating and maintaining a custom Lambda function that has logic to prevent KMS key deletion, which adds operational overhead.
Option D is not a valid solution because it only notifies the administrators of the DeleteKey operation, but does not cancel it.

Which solution will meet these requirements MOST cost-effectively?
- A . Use AWS Budgets to download data for the past 3 months into a csv file. Look up the desired information.
- B . Load AWS Cost and Usage Reports into an Amazon RDS DB instance. Run SQL queries to gel the desired information.
- C . Tag all the AWS resources with a key for cost and a value of the application’s name. Activate cost allocation tags Use Cost Explorer to get the desired information.
- D . Tag all the AWS resources with a key for cost and a value of the application’s name. Use the AWS Billing and Cost Management console to download bills for the past 3 months. Look up the desired information.
Correct Answer: C
C
Explanation:
This solution is the most cost-effective and efficient way to break down costs per application. Tagging Resources: By tagging all AWS resources with a specific key (e.g., "cost") and a value representing the application’s name, you can easily identify and categorize costs associated with each application. This tagging strategy allows for granular tracking of costs within AWS. Activating Cost Allocation Tags: Once tags are applied to resources, you need to activate cost allocation tags in the AWS Billing and Cost Management console. This ensures that the costs associated with each tag are included in your billing reports and can be used for cost analysis. AWS Cost Explorer: Cost Explorer is a powerful tool that allows you to visualize, understand, and manage your AWS costs and usage over time. You can filter and group your cost data by the tags you’ve applied to resources, enabling you to easily see the cost breakdown for each application. Cost Explorer also supports generating regular reports, which can be scheduled and emailed to stakeholders.
Why Not Other Options?
Option A (AWS Budgets): AWS Budgets is more focused on setting cost and usage thresholds and monitoring them, rather than providing detailed cost breakdowns by application.
Option B (Load Cost and Usage Reports into RDS): This approach is less cost-effective and involves more operational overhead, as it requires setting up and maintaining an RDS instance and running SQL queries.
Option D (AWS Billing and Cost Management Console): While you can download bills, this method is more manual and less dynamic compared to using Cost Explorer with activated tags.
