In the exhibit, Switch A is an EX4200. VLAN10 is receiving tagged as well as untagged traffic from different ports. The administrator wants to mirror all tagged and untagged traffic entering VLAN10 to analyzer port ge-0/0/10. All VLAN tags must be preserved for traffic that is mirrored to the analyzer port.
Which configuration will achieve this?

• A.  set ethernet-switching-options analyzer vlan10_analyzer input ingress vlan VLAN10 set ethernet-switching-options analyzer vlan10_analyzer output interface ge-0/0/10.0 set vlans VLAN10 interface ge-0/0/10.0
• B.  set ethernet-switching-options analyzer vlan10_analyzer input ingress vlan VLAN10 set ethernet-switching-options analyzer vlan10_analyzer output interface ge-0/0/10.0 set vlans default interface ge-0/0/10.0
• C.  set ethernet-switching-options analyzer vlan10_analyzer input vlan VLAN10 interface xe-1/0/0.0 set ethernet-switching-options analyzer vlan10_analyzer input vlan VLAN10 interface ge-
  0/0/2
  set ethernet-switching-options analyzer vlan10_analyzer output interface ge-0/0/10.0
• D.  set ethernet-switching-options analyzer vlan10_analyzer input interface xe-1/0/0.0 set ethernet-switching-options analyzer vlan10_analyzer input interface ge-0/0/2 set ethernet-switching-options analyzer vlan10_analyzer output interface ge-0/0/10.0
