The correct answer is D: Use Amazon GuardDuty. Enable runtime monitoring.. Important note: The stated correct answer (D) appears to be incorrect for this question. Option A is almost certainly the right answer, and I'd be doing you a disservice by explaining D as correct. --- Why A is correct: AWS X-Ray with active tracing enabled for Amazon SNS capture
Question
A company wants to send notifications to customers to advertise a sale on the company's products. The company needs to use Amazon Simple Notification Service (Amazon SNS) FIFO topics. The company needs to examine the rate at which the topics send notifications and the latency with which the topics send notifications. Which solution will meet these requirements with the MOST operational efficiency?
Options
- AUse AWS X-Ray. Enable active tracing for Amazon SNS.
- BUse the Amazon CloudWatch NumberOfNotificationsFailed metric.
- CUse AWS CloudTrail to log all Amazon SNS API calls.
- DUse Amazon GuardDuty. Enable runtime monitoring.
Explanation
Important note: The stated correct answer (D) appears to be incorrect for this question. Option A is almost certainly the right answer, and I'd be doing you a disservice by explaining D as correct.
Why A is correct: AWS X-Ray with active tracing enabled for Amazon SNS captures distributed trace data, giving you both throughput (rate) and end-to-end latency metrics for your SNS topics - exactly what the question asks for, with minimal configuration overhead.
Why the distractors are wrong:
- B - The
NumberOfNotificationsFailedCloudWatch metric only tracks failures, not delivery rate or latency for successful notifications. - C - CloudTrail logs API calls for auditing and governance purposes; it captures who did what, not performance characteristics like rate or latency.
- D - Amazon GuardDuty is a threat detection/security service. Runtime monitoring detects suspicious process behavior in compute workloads. It has no relevance to SNS notification rate or latency monitoring.
Memory tip: When a question asks about latency and throughput observability, think X-Ray (tracing) first. X-Ray = performance visibility across distributed services. GuardDuty = security threats. CloudTrail = API audit logs. Keep these three pillars separate: observe, secure, audit.
I'd recommend verifying this question against an authoritative source - the marked answer (D) appears to be a typo or error in whatever question bank you're using.
