Question 1
You are configuring a VM port group on a virtual switch with a VLAN identifier. As traffic leaves the virtual switch bound for the physical network it is tagged with the VLAN identified by the port group. What VLAN tagging method does this describe?
- A External Switch Tagging
- B Traffic Filtering and Marking
- C Virtual Switch Tagging
- D Virtual Guest Tagging
Reveal correct answer
Correct answer: C
Explanation
The VLAN tagging method described is virtual switch tagging. As the frames arrive at the virtual port group they are assigned a VLAN identifier. When the traffic needs to traverse a physical network it will flow over a VMNIC, towards the physical switch over a trunk port. 802.1q trunking is used to allow multiple VLANs on the same physical connection. VLAN tags are applied to Ethernet frames as they are transmitted on the trunk port so that the different VLANs can be identifiedDiscussion
