consider serialization delay? (Choose two )
E (only packet size and line rate affect serialization delay, so B/D are off)
E, C. E makes sense since serialization delay depends on both packet size and link speed, which lines up with what I know. C says serialization delay is the time to transmit the packet on the media, which seems accurate if you think of serialization as the actual bit-by-bit transmission time. Even if it’s a bit ambiguous, propagation delay is a separate concept from serialization delay, so I’m okay with including C here. A and B don’t quite work because serialization delay isn’t fixed—it varies with packet size, so those options feel off.
E imo, serialization delay varies with both line rate and packet size, so that part’s clear. A is wrong because serialization delay isn’t invariable—it depends on packet size too, not just line rate.
C/E? C describes serialization delay as the time to transmit the packet on the physical media, which aligns with it being the bit-by-bit output time. Meanwhile, E adds that it depends on both the interface line rate and packet size, which matches the basic formula for serialization delay. A and D don’t fit because the delay isn’t invariable—it changes with packet size and line rate. B is off since the type of packet doesn’t directly affect serialization delay, just its size does. So C and E together cover both what serialization delay is and what it depends on.
E, C. Serialization delay definitely depends on both the line rate and packet size, so E makes sense. I also think C tries to capture the essence of serialization delay—it's basically the time to push all packet bits onto the wire. Even if the wording is a bit off or vague, it’s describing what serialization delay really is, unlike some options that add unrelated variables like packet type. So I’d pick E and C here.
Not B, serialization delay isn't variable based on packet type, just size and line rate.
C/E? Serialization delay is definitely about how long it takes to push the packet bits onto the wire, so C fits. And E covers the two main factors: line rate and packet size. Makes sense.
C and E seem right here, serialization depends on packet size and line rate.
