Nokia 4A0-107 Exam - Topic 3 Question 93 Discussion

Actual exam question for Nokia's 4A0-107 exam

Question #: 93
Topic #: 3

An egress port scheduler applied to an Ethernet port has a configured bandwidth of 100 Mbps. All frames transmitted on the port are 80 bytes. What is the aggregate transmit bandwidth of all queues using the port scheduler?

A100Mbps * 20/(80 + 20) = 20 Mbps

B100Mbps * 80/(80 + 20) = 80 Mbps

C100Mbps

D100+ 100 * 20/(80 + 20) = 120 Mbps

I’m confused! Why not just stick with the 100 Mbps?

D looks interesting, but I think it overestimates the bandwidth.

I agree with B. The calculation seems right for the frame size.

I’m leaning towards C. The port scheduler should just use the full 100 Mbps.

Why would the aggregate be less than the configured bandwidth?

Wait, how does that add up to 120 Mbps? Sounds off.

I think B is the right answer, 80 Mbps makes sense.

A) 100Mbps * 20/(80 + 20) = 20 Mbps. Hmm, I'm not sure about the math here.

D) 100+ 100 * 20/(80 + 20) = 120 Mbps. Wait, is that even possible? Seems a bit too high.

C) 100Mbps. Simple and straightforward, I like it.

I recall that the total bandwidth should be the configured bandwidth, so maybe option C is the answer?

I’m a bit confused about how the egress port scheduler affects the total bandwidth. I think I need to review that part again.

This question feels similar to one we practiced where we had to adjust bandwidth based on frame sizes. I think option B might be right.

I remember something about calculating bandwidth based on frame size, but I'm not entirely sure how to apply it here.

Got it, I think the answer is B) 80 Mbps. The formula takes the configured bandwidth and adjusts it based on the frame size to get the actual transmit bandwidth.

Alright, I'm going to try to solve this by plugging the values into the formula. The configured bandwidth is 100 Mbps, and the frame size is 80 bytes, so I need to calculate 100 Mbps * 80/(80 + 20) to get the aggregate transmit bandwidth.

I think the key is to use the formula for calculating the effective bandwidth based on the frame size and the configured bandwidth. Let me work through that step-by-step.

Okay, the question says the frames are 80 bytes, and the port has a configured bandwidth of 100 Mbps. I'm not sure how to use that information to calculate the aggregate transmit bandwidth though.

Hmm, this looks like it's asking about the bandwidth of an Ethernet port scheduler. I think I need to consider the frame size and the configured bandwidth to figure this out.

Yeah, 80 bytes is pretty small for Ethernet.
