Exam HPE6-A72 topic 1 question 68 discussion

Correct Answer:1/1/4 Tagged VLANs 1. A host will send a frame without a tag 2. The frame enters an untagged port on switch 1, configured with VLAN 10 in this case. The switch adds the VLAN tag to the frame 3. Switch 1 determines that port 2 should send this frame to switch 2. This is a tagged port, so it checks that VLAN 10 is allowed on this port. If it is, it leaves the tag intact, and sends the frame. If VLAN 10 is not allowed, it drops the frame 4. Switch 2 receives the frame on tagged port 1. This switch also determines if VLAN 10 is allowed on this port, and drops it if it is not. Switch 2 determines that port 2 should send the frame 5. Since port 2 is an untagged port, it strips the tag from the frame, and then sends it 6. Host B receives the untagged frame https://networkdirection.net/articles/network-theory/taggeduntaggedandnativevlans/

1/1/2 is correct. frame strips tag off the last trunk port. It then floods the untagged frame out all access ports within that broadcast domain

It is encapsulated at 1/1/3 and remains so until it is sent to the server on 1/1/4.

If the link between the Server and Access-2 is an access port, then on 1/1/2

1/1/4 is correct. Cause when the packet is received on port 1/1/2, then switch check the frame header to see the destinantion, if it is local enddevice then removes the tag and send it, if it is another sw then it dont remove the tag.

Port 1/1/2 on Access-2 is correct. "As frame arrives at the end of the trunk link the tag is removed and the frame is sent to the correct access link port according to the switch's table, so that the receiving end is unaware of any VLAN information." https://www.firewall.cx/networking-topics/vlan-networks/219-vlan-tagging.html

1/1/2 is a trunk port. The answer given is correct.

Port 1/1/2 on Access-2 is Correct
