A start-up firm is using Amazon EC2 instance for web applications. The IT Team is observing some of the EC2 instances unresponsive & remotely looking for the crash dump to diagnose further root cause. Which of the following can be used for the collection of crash dump files?

Answer options:

A.Run EC2:SetDiagnosticInterrupt API to generate crash dump data files.
B.Run EC2:DebugDiagnosticInterrupt API to generate crash dump data file.
C.Run EC2:SendDiagnosticInterrupt API to generate crash dump data files.
D.Run EC2:RunDiagnosticInterrupt API to generate crash dump data files.

Correct Answer – C 
For getting crash dump remotely for an unresponsive EC2 instance, EC2:SendDiagnosticInterrupt API can be used which based upon OS configuration can do multiple things like getting crash dump, obtain a backtrace, load a kernel replacement or restart a system.
Option A, B & D are incorrect as these are not the correct APIs to get crash dump.
