A SysOps administrator must create a solution that immediately notifies software developers if an AWS Lambda function experiences an error.
Which solution will meet this requirement?

  1. Create an Amazon Simple Notification Service (Amazon SNS) topic with an email subscription for each developer. Create an Amazon CloudWatch alarm by using the Errors metric and the Lambda function name as a dimension. Configure the alarm to send a notification to the SNS topic when the alarm state reaches ALARM.
  2. Create an Amazon Simple Notification Service (Amazon SNS) topic with a mobile subscription for each developer. Create an Amazon EventBridge (Amazon CloudWatch Events) alarm by using the LambdaError as the event pattern and the SNS topic name as a resource. Configure the alarm to send a notification to the SNS topic when the alarm state reaches ALARM.
  3. Verify each developer email address in Amazon Simple Email Service (Amazon SES). Create an Amazon CloudWatch rule by using the LambdaError metric and developer email addresses as dimensions. Configure the rule to send an email through Amazon SES when the rule state reaches ALARM.
  4. Verify each developer mobile phone in Amazon Simple Email Service (Amazon SES). Create an Amazon EventBridge (Amazon CloudWatch Events) rule by using Error as the event pattern and the Lambda function name as a resource. Configure the rule to send a push notification through Amazon SES when the rule state reaches ALARM.

A company has a private Amazon S3 bucket that contains sensitive information. A SysOps administrator needs to keep logs of the IP addresses from authentication failures that result from attempts to access objects in the bucket. The logs must be stored so that they cannot be overwritten or deleted for 90 days.
Which solution will meet these requirements?

  1. Create an AWS CloudTrail trail. Configure the log files to be saved to Amazon CloudWatch Logs. Configure the log group with a retention period of 90 days.
  2. Create an AWS CloudTrail trail. Configure the log files to be saved to a different S3 bucket. Turn on CloudTrail log file integrity validation for 90 days.
  3. Turn on access logging for the S3 bucket. Configure the access logs to be saved to Amazon CloudWatch Logs. Configure the log group with a retention period of 90 days.
  4. Turn on access logging for the S3 bucket. Configure the access logs to be saved in a second S3 bucket. Turn on S3 Object Lock on the second S3 bucket, and configure a default retention period of 90 days.

Answer(s): D

  2. Verify that the application is running on the protocol and the port that the listener is expecting.
  3. Verify the listener priority in the ALB. Change the priority if necessary.
  4. Verify the maximum number of instances in the Auto Scaling group. Change the number if necessary.

Answer(s): B
