Recently, a network interface card in an ESXi 5.x host has been experiencing inconsistent connectivity states.
Which two methods can be used to quickly identify the issue and immediately notify an administrator so that the issue can be resolved? (Choose two.)
A.
Set up an alarm with the Lost Network Connectivity trigger to send an email for notification when the connection is lost.
B.
Set up an alarm with the Lost Network Redundancy trigger to send an email for notification when the connection is lost.
C.
Set up an alarm with the Network Redundancy Degraded trigger and configure an SNMP trap for notification when the connection is lost.
D.
Set up an alarm with the Lost Network Connectivity trigger and configure an SNMP trap for notification when the connection is lost.
I thing the correct answer should be A and C because A and D is the same alarm and if there are more than one physical nic, it will never show alarm if only one nic is down.
Good explanation of the alarms is at

Only A & D can be 100% correct. B and C assume that the NIC is part of a vSwitch with multiple uplinks. This is not specified. In order for the Network Redundancy Degraded alarm trigger, the NIC would need to be part of a team.
Think of a server with only one NIC. There is no redundancy to begin with.
