Q: 7
A developer is monitoring an application that runs on an Amazon EC2 Instance. The developer has
configured a custom Amazon CloudWatch metric with data granularity of 1 second. It any issues
occur, the developer wants to be notified within 30 seconds by Amazon Simple Notification Service
(Amazon SNS).
What should the developer do to meet this requirement?

Option A
A is right here, not B. Only high-resolution CloudWatch alarms can work with 1-second granularity and trigger SNS within 30 seconds. The others won’t get alerts out fast enough. Pretty sure on this but open to other takes.
A imo . Default alarms can only check every 60 seconds, so you need high-res for that fast notification.
Probably A since only a high-res CloudWatch alarm supports sub-minute intervals like 30 seconds. The rest wouldn't notify that fast, if I'm reading it right. Pretty sure about this, but open to other opinions if I missed something.
C or D, not confident here because both seem off for the 30 sec part.
Nah, it's not B. High-res alarm is the only one that supports 30 sec notifications, so A.
Nah, I think A is the way to go here. High-resolution alarms are needed for that sub-minute alerting, since default CloudWatch metrics like D cap you at a 60 second minimum and wouldn't notify fast enough. Anyone disagree?
My vote is A, saw a similar scenario in practice exams and high-res alarms were required for sub-minute alerts.
A
A for sure here. High-res alarms let you trigger notifications within 30 seconds which is what the question wants, none of the others support that quick of a response. If I've missed something about custom metrics let me know, but pretty sure this is the best fit.
Be respectful. No spam.
