What must occur before a workstation can exchange HTTP packets with a web server?
A.
A UDP connection must be established between the workstation and its default gateway.
B.
A UDP connection must be established between the workstation and the web server.
C.
A TCP connection must be established between the workstation and its default gateway.
D.
A TCP connection must be established between the workstation and the web server.
E.
An ICMP connection must be established between the workstation and its default gateway.
F.
An ICMP connection must be established between the workstation and the web server.
Explanation:
answer is D
We know that HTTP uses TCP so we are left with 2 options C or D.
the correct answer us D => TCP connection must be established with the web server.
*Note that the default gateway is a layer 3 device so no TCP connection will be established. If needed the host will send ARP request (broadcast to get the MAC of the router). Again this is not a TCP connection.
I hope this is helpful
