Explanation / Answer

36. The most common messages in SNMP are trap messages. Trap messages are used to inform the SNMP manager that something happened at the agent. FYI they are async.

39. SNMP uses UDP most of the times to send trap requests. It allows port 162 UDP for agent to send MIB data to manager and 161 for the opposite. Hence the answer is 'A'. FYI TCP is possible but UDP is more common.

38. SNMP Inform is message from manager that says 'Hey Agent, I got your trap message'. So its manager -> agent.
