Two routers, r1 and r2, connect using an ethernet over mpls service the service provides point-to-point service between these two routers only, as layer 2 ethernet service. which of the following are most likely to be true about this wan? (choose two)a. r1 will connect to a physical ethernet link, with the other end of the cable connected to r2.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. c. r1 will forward data link frames to r2 using an hdlc header/trailer. d. r1 will forward data link frames to r2 using an ethernet header/trailer.

Create a function (prob3_6) that will do the following: input a positive scalar integer x. if x is odd, multiply it by 3 and add 1. if the given x is even, divide it by 2. repeat this rule on the new value until you get 1, if ever. your program will output how many operations it had to perform to get to 1 and the largest number along the way. for example, start with the number 3: because 3 is odd, we multiply by 3 and add 1 giving us 10. 10 is even so we divide it by 2, giving us 5. 5 is odd so we multiply by 3 and add one, giving us 16. we divide 16 (even) by two giving 8. we divide 8 (even) by two giving 4. we divide 4 (even) by two giving 2. we divide 2 (even) by 2 to give us 1. once we have one, we stop. this example took seven operations to get to one. the largest number we had along the way was 16. every value of n that anyone has ever checked eventually leads to 1, but it is an open mathematical problem (known as the collatz conjectureopens in new tab) whether every value of n eventually leads to 1. your program should include a while loop and an if-statement.
