All four ports for sure!

Only on port 1/1/1? Nah, that can't be right.

I thought it would go to all ports too, but isn't there a limit?

Definitely on all ports except 1/1/1.

It's a broadcast frame, so it goes everywhere!

I’m confused about this one. I thought broadcasts went to all ports, but does it really exclude the incoming port? I need to double-check my notes.

This reminds me of a practice question where we had to identify how switches handle broadcasts. I feel like it could be all ports, but I’m leaning towards B too.

I'm not entirely sure, but I remember something about how broadcast frames are treated. Maybe it’s option B?

I think the frame is a broadcast since the destination MAC is all Fs, so it should go out on all ports except the one it came in on, right?

This is a good test of my understanding of MAC address forwarding. I'll methodically work through the details and use my knowledge of switch behavior to arrive at the correct answer.

I'm a little confused by the MAC FDB table. I'll need to review my notes on how switches handle broadcast frames and look closely at the information provided in the exhibit.

Okay, I've got this. The source MAC address is in the FDB, so I just need to check which port that MAC address is associated with. Then I can determine the forwarding ports based on the broadcast destination.

Hmm, I'm a bit unsure about this one. The destination MAC address is a broadcast address, so I'll need to think through how that affects the forwarding decision.

This looks like a straightforward MAC address forwarding question. I'll need to carefully analyze the MAC FDB table to determine which ports the frame will be forwarded on.

I've got a good feeling about this one. Implementing an API gateway seems like the most straightforward way to handle the security and formatting requirements across the different systems of engagement.

Hmm, this looks like a tricky one. I'll need to carefully read through the options and think about which combination of factors could prevent data entry on the form.

Wait, is this a trick question? I mean, who doesn't know that a broadcast frame needs to go out on all ports? C is the only logical choice, unless the exam writers are trying to make us all look like fools.

Ah, the old broadcast MAC address dilemma. I bet the exam writers are trying to catch us off guard, but C is definitely the right answer here. Easy peasy!

Let's agree to disagree, I believe it's D) On none of the ports.
LI
Lizbeth

I'm sticking with C) On all four ports, it just makes sense.
AR
Argelia

No way, it has to be B) On all ports except 1/1/1.
JA
Jacquelyne

Are you sure about that? I think it's A) Only on port 1/1/1.
SH

This question is a piece of cake. When you see a broadcast MAC address, you know the frame is supposed to be forwarded on all ports. C is the right choice, no doubt about it.
KE
Kendra
1 year ago
Hmm, the question is pretty straightforward. If the destination MAC is a broadcast, the frame should go out on all ports. C is the way to go!
AL
Albina
1 year ago
Definitely, C is the best choice since it's a broadcast frame. It will go out on all ports.
VA
Val

Definitely, C is the best choice considering the MAC addresses involved.
MA
Marcelle

Yes, it makes sense that the frame would be forwarded on all four ports in this case.
YU
Yuonne
1 year ago
Yes, that's right. The frame will be forwarded out on all four ports in this case.
CA
Carlee

I agree, C is the correct answer because the destination MAC address is a broadcast.
LO
Loreta

I agree, C is the correct answer because the destination MAC is a broadcast address.
PH
Phil

The destination MAC address is a broadcast address, so the frame should be forwarded on all ports. I think C is the correct answer.
CH

User 4: Agreed, C sounds like the right choice.
LE

User 3: So, the correct answer is C) On all four ports.
TO

User 2: Yeah, the destination MAC address is a broadcast address.
LE

User 1: I think the frame will be forwarded on all ports.
KA
Kanisha

I believe the correct answer is B) On all ports except 1/1/1, because broadcast frames are forwarded to all ports except the incoming port.
SV

I agree with Magda, because the destination MAC address is a broadcast address.
