Hey Folks,
Thank you for your help and your cooperation each time someone posts a question, i really appreciate it!
However, i wish someone could provide me with the answer to this question!
Which WAN technology establishes a dedicated constant point-to-point connection between two sites?
Actually, option D is also correct. i hope this one will be on the exam, at least the answers are clearer.
Personally, I am going with the last option. as the leased link establishes a dedicated constant point-to-point connection between two sites.
the ATM is cell-switched and ISDN is circuit-switched. Thus, the first and third options are excluded, I am not sure about the two remaining ones, but I think the right answer is D.
You’re right, The second option is for sure false because the Frame Relay is packet-switched. However, the “Leased lines” is the right one referring to Gianna’s explanation.
Agreed, the answer is A. However, the other options have nothing to do with a point-to-point connection, It’s just there to trick you.
