Question 8
What is the alert message generated by SNMP agents called ?
A. TRAP
B. INFORM
C. GET
D. SET
Answer: A B
Explanation
A TRAP is a SNMP message sent from one application to another (which is typically on a remote host). They’re purpose is merely to notify the other application that something has happened, has been noticed, etc. The big problem with TRAPs is that they’re unacknowledged so you don’t actually know if the remote application received your oh-so-important message to it. SNMPv2 PDUs fixed this by introducing the notion of an INFORM, which is nothing more than an acknowledged TRAP.
