Answer: c)Roaming user profiles
Explanation:Roaming user profiles are those profiles that creates the copy from the local profile and get stored in the network server. Roaming user profiles haves the function of getting logged in any computer system that the user is processing by getting downloaded.
It has the advantage of not creating profiles on every computer system that user wants to login .Thus, the correct answer is option(c) because other profiles mentioned in the option cannot copy the profile in the server and so do not have capability to be accessed in other computer system.
Answer: b) R1 will connect to a physical Ethernet link, with the other end of the cable connected to a device at the WAN service provider point of presence.
.d) R1 will forward data link frames to R2 using an Ethernet header/trailer.
Explanation:
Here we have to understand what is MLPS. MLPS is a protocol which identifies the shortest route for the transfer of messages between routers instead of the longest route.
Here we are given a WAN which is a wide area network. Using layer 2 Ethernet service the frames are transmitted across the routers within the WAN.
Option A is incorrect as as connecting the other end of the cable to the R2 would reduce the functionality of the WAN. Option C is incorrect as HDLC header trailer has no effect.
Option B and D are correct as Ethernet header/ trailer has the same size every frame and to maintain the functionality of the WAN one end must be connected to point of presence(PoP).
