Topic: 350-601 topic 1 question 393

Refer to the exhibit. A network engineer must monitor the traffic from the server on VLAN 80. All source traffic from the server must be captured on the monitoring device. Which configuration set meets these requirements?

A.
switch(config-monitor)# destination interface ethernet 1/1switch(config-monitor)# source vlan 80
B.
switch(config-monitor)# destination interface ethernet 1/1switch(config-monitor)# filter vlan 80
C.
switch(config-monitor)# destination interface ethernet 1/2switch(config-monitor)# filter vlan 80 rx tx
D.
switch(config-monitor)# destination interface ethernet 1/2switch(config-monitor)# source vlan 80 rx

Re: 350-601 topic 1 question 393

B is correct
A is wrong - Source VLANs are supported only in the ingress direction (rx).
C and D are no sense, traffic analyzer is on e1/1 interface

Re: 350-601 topic 1 question 393

Sure A is the correct

Re: 350-601 topic 1 question 393

A is correct
Rx is implicit for source vlan

Re: 350-601 topic 1 question 393

D is right answer here
When you specify a VLAN as a SPAN source, all supported interfaces in the VLAN are SPAN sources.

Re: 350-601 topic 1 question 393

A is ok

The following example shows configuring a VLAN SPAN source:
...
switch(config-monitor)# source vlan

Re: 350-601 topic 1 question 393

D is the correct answer, because source vlan only can define with rx. Check it in my lab.

TULLY01(config-monitor)# source vlan 80
Warning:  Tx Vlan Span is not supported
TULLY01(config-monitor)# source vlan 80 both
Warning:  Tx Vlan Span is not supported
TULLY01(config-monitor)# source vlan 80 rx
TULLY01(config-monitor)#

Re: 350-601 topic 1 question 393

I will select answer B
=================================================
Source VLANs are supported only in the ingress direction.

Re: 350-601 topic 1 question 393

It´s correct

Re: 350-601 topic 1 question 393

All source traffic from the server must be captured
