NEW QUESTION # 349
A developer is debugging an issue with an application that is based on an AWS Lambda function. The Lambda function intermittently fails during a 1-hour window. The developer needs to investigate the root cause of the intermittent failures. The application sends logs to an Amazon CloudWatch Logs log group. The developer must be able to collect logs that relate to Lambda function failures. The developer must capture the dates and times at which the failures occurred. Which solution will meet these requirements in the MOST operationally efficient way?
Answer: C
Explanation:
The correct answer is B because Amazon CloudWatch Logs Insights is the AWS-native tool for interactively searching, filtering, and analyzing log data that is already stored in CloudWatch Logs. In this case, the developer needs to investigate intermittent Lambda failures within a specific 1-hour period , identify logs related to failures, and capture the timestamps of those failures. Logs Insights is purpose-built for exactly this kind of operational troubleshooting.
AWS documentation describes Logs Insights as a fully integrated log analytics capability that can query log groups by time range and pattern. The developer can run a query that filters for error-related log messages, extracts timestamp fields, and sorts the results to find exactly when failures occurred. This is highly efficient because it does not require exporting logs, writing custom parsing scripts, or manually browsing through streams.
Option A is possible but not the most operationally efficient. Browsing logs through the CLI is slower and more manual, especially for intermittent failures. Option C is inefficient because downloading logs to a local machine adds unnecessary steps and operational overhead. Option D can work for large-scale analytics, but exporting to S3 and querying with Athena is more complex than needed for logs that are already in CloudWatch Logs.
Therefore, the best solution is to use CloudWatch Logs Insights to query the Lambda log group for failure patterns and timestamps. This provides fast, targeted, and operationally efficient troubleshooting directly within AWS.
NEW QUESTION # 350
A company has an Amazon S3 bucket containing premier content that it intends to make available to only paid subscribers of its website. The S3 bucket currently has default permissions of all objects being private to prevent inadvertent exposure of the premier content to non-paying website visitors.
How can the company Limit the ability to download a premier content file in the S3 Bucket to paid subscribers only?
Answer: D
Explanation:
Explanation
This solution will limit the ability to download a premier content file in the S3 bucket to paid subscribers only because it uses a pre-signed object URL that grants temporary access to an S3 object for a specified duration. The pre-signed object URL can be generated by the company's website when a paid subscriber requests a download, and can be verified by Amazon S3 using the signature in the URL. Option A is not optimal because it will allow anyone to download the content from the S3 bucket without verifying their subscription status. Option C is not optimal because it will require additional steps and costs to configure multi-factor authentication for accessing the S3 bucket objects, which may not be feasible or user-friendly for paid subscribers. Option D is not optimal because it will not prevent non-paying website visitors from accessing the S3 bucket objects, but only encrypt them at rest.

NEW QUESTION # 351
A developer maintains applications that store several secrets in AWS Secrets Manager. The applications use secrets that have changed over time. The developer needs to identify required secrets that are still in use. The developer does not want to cause any application downtime.
What should the developer do to meet these requirements?
Answer: C
Explanation:
This solution will meet the requirements by using AWS Config to monitor and evaluate whether Secrets Manager secrets are unused or have been deleted, based on specified time periods. The secrets manager-secret- unused managed rule is a predefined rule that checks whether Secrets Manager secrets have been rotated within a specified number of days or have been deleted within a specified number of days after last accessed date. The Amazon EventBridge rule will trigger a notification when the AWS Config managed rule is met, alerting the developer about unused secrets that can be removed without causing application downtime.
Option A is not optimal because it will use AWS CloudTrail log file delivery to an Amazon S3 bucket, which will incur additional costs and complexity for storing and analyzing log files that may not contain relevant information about secret usage. Option C is not optimal because it will deactivate the application secrets and monitor the application error logs temporarily, which will cause application downtime and potential data loss.
Option D is not optimal because it will use AWS X-Ray to trace secret usage, which will introduce additional overhead and latency for instrumenting and sampling requests that may not be related to secret usage.

NEW QUESTION # 352
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?
Answer: A
Explanation:
* Problem:CloudFormation updates reset Parameter Store parameters, disrupting application behavior.
* Deletion Policy:CloudFormation has a deletion policy that controls resource behavior when a stack is deleted or updated. The 'Retain' policy instructs CloudFormation to preserve a resource's current state.
* Least Development Effort:This solution involves a simple CloudFormation template modification, requiring minimal code changes.
NEW QUESTION # 353
A developer created an AWS Lambda function that performs a series of operations that involve multiple AWS services. The function's duration time is higher than normal. To determine the cause of the issue, the developer must investigate traffic between the services without changing the function code Which solution will meet these requirements?
Answer: A
Explanation:
Tracing Distributed Systems: AWS X-Ray is designed to trace requests across services, helping identify bottlenecks in distributed applications like this one.
No Code Changes: Enabling X-Ray tracing often requires minimal code changes, meeting the requirement.
Identifying Bottlenecks: Analyzing X-Ray traces and logs will reveal latency in communications between different AWS services, leading to the high duration time.
