A.A link has a transmission rate of 100 Mb/s, a frame size of 100B and you can ignore the propagation and processing delays. The value of a = 2 is when the ACK is sent in an S-Frame.
B.A link has a transmission rate of 100 Mb/s, a frame size of 100B and you can ignore the propagation and processing delays. The value of a = 2 is when the ACK is sent in an S-Frame.
C.If the probability of frame error is 0.5% and the bit error rate is reduced by half, then the frame error rate is approximately 0.25%
D.If the probability of frame error is 0.5% and the bit error rate is reduced by half, then the frame error rate is approximately 0.25%
E.To have at least 32 Host IP addresses in each subnet, the mask has to be at most /27
F.Consider the control field in HDLC is 00000000 This is an Unnumbered Frame (U-Frame)
G.Consider the control field in HDLC is 00000000 This is an Unnumbered Frame (U-Frame)
H.Consider the control field in HDLC is 00000000 This is an Unnumbered Frame (U-Frame)
I.When using a CRC-16 (16 bit Cyclic Redundancy Check) it can almost never detect if there has been an error in the data.

Step-by-Step Analysis
The question asks you to select all the correct statements among the given options. I will evaluate each option listed in the answer_options, explaining why it is correct or incorrect, and I will cover duplicates and similar statements as separate items where they appear.
Option A: 'A link has a transmission rate of 100 Mb/s, a frame size of 100B and you can ignore the propagation and processing delays. The value of a = 2 is when the ACK is sent in an S-Frame.'
- This statement mixes two concepts: the timing parameter a (often used in performance formulas for frames/ACK timing) and a specific scenario about when an ACK is sent in an S-Frame. Since the prompt asks for correctness about general networking statements, this claim hinges on a very particular protocol/analytical context. Without additional context (which frame size, RTT, and whether ACK timing follows a particular discrete rule), we cannot reliably deem this universally true. In many standard analyses, the value of a is not universally fixed to 2 for ACKs in S-frames, and different ARQ or HDLC-like protocols have different timing rules. Therefore, this option is likely incorrect or at least not universally correct.
Option B: 'A link has a transmission rate of 100 Mb/s, a frame size of 100B and you can ignore the propagation and processing delays. The value of a = 2 is when the ACK is sent in an S-Frame.'
- This is essentially the same as Optio......Login to view full explanationLog in for full answers
