Refer to the exhibit. An engineer monitors ingress traffic from Host-A and all traffic for VLAN 20 from Host-B. Which configuration must be implemented to monitor and export traffic to Network Analyzer?
A.
SW-1(config)# monitor session 5 SW-1(config-monitor)# source interface ethernet 1/2 rx SW-1(config-monitor)# source interface ethernet 1/1 tx SW-1(config-monitor)# source vlan 20 both SW-1(config-monitor)# destination ip 10.10.10.1 SW-1(config-monitor)# no shut
B.
SW-1(config)# monitor session 5 type erspan-source SW-1(config-erspan-src)# source interface ethernet 1/2 rx SW-1(config-erspan-src)# source vlan 20 both SW-1(config-erspan-src)# destination ip 10.10.10.1 SW-1(config-erspan-src)# erspan-id 111 SW-1(config-erspan-src)# no shut
C.
SW-1(config)# monitor session 5 SW-1(config-monitor)# source interface ethernet 1/2 rx SW-1(config-monitor)# source interface ethernet 1/1 both SW-1(config-monitor)# source vlan 20 both SW-1(config-monitor)# destination interface ethernet 2/1 SW-1(config-monitor)# no shut
D.
SW-1(config)# monitor session 5 type erspan SW-1(config-erspan-src)# source interface ethernet 1/2 rx SW-1(config-erspan-src)# source interface ethernet 1/1 both SW-1(config-erspan-src)# destination ip 10.10.10.1 SW-1(config-erspan-src)# mtu 1000 SW-1(config-erspan-src)# no shut
B is correct.
look Step 5
source {interface type number| vlanvlan-ID}
[, | -| both | rx | tx]

I think this is only for Nexus as that's the only place I get that error.
I tried on 3750X and 3850 both success
SW-1(config)#monitor session 5 source vlan 20 both
SW-1(config)#
Answer is B
B is correct
SW-1(config)# monitor session 5 type erspan-source
SW-1(config-erspan-src)# source interface ethernet 1/2 rx
SW-1(config-erspan-src)# source vlan 20 both
SW-1(config-erspan-src)# destination ip 10.10.10.1
SW-1(config-erspan-src)# erspan-id 111
SW-1(config-erspan-src)# no shut
