i've been studying with a group of friends, but none of us could come up with a definitive answer for the following questions:

my answer is a. my friend says b.
which one is fastest?
a. router
b. switch
c. bridge
d. hub
my answer is b switch. my friend says d hub.
who's right?


Layer 2 Question
The correct answer is Switch.

I have to disagree with regards to a switch being faster than hub. Although a switch is more likely to make for faster network than then a hub this is not the question. Which one is fastest? a. router, b. switch, c. bridge, d. hub. A hub operates only at the physical layer of the OSI model receiving and repeating data on all interfaces. A switch on the other hand operates at the data link layer of the OSI model receiving, processing data link layer addressing information and repeating information on appropriate interfaces. This additional processing adds laitance to the re-transmission of data. As the question does not indicate any implementation I believe the answer to be d. hub. Maybe it’s me maybe it’s the question. Feedback would be appreciated.

The faster is switch, to confirm please see cisco's book ICND. The same question was in exams and I got correct answer. KSheikh

Does it not depend on what is connected to switch/hub and the chosen switch mode?

I think it's a simple question because it's the advantage of switch comparing to others.

which one is fastest?
a. router
b. switch

heh. somewhat controversial. This question is too vague. If you ask me, it doesn't give you enough information.

but if I were to give you an answer, I'd say hub is faster. A switch operates at the data link layer. Due to it's switching functions, the switch has latency.

The switch have to be the correct answer on a question like this.

But if you look at how a switch and a hub is built. And if fast and slow is related to the time it takes before a frame starts to come out from a device after it have start entering another port on the same device it is not hard to understand that a hub actualy is faster.
But that is if only two stations are connected to the hub. And only one of them is sending any data.
In a normal network a switch is making the network faster than a hub can do.

This is a poor question however, it provokes thought. Most 3rd party exam questions come from poor questions that were thrown out of the certification exam database. This question will send you down a rabbit hole for hours researching, but that is not a bad thing. There is not enough information to go with this question. All replys seem convincing enough, such as; a hub because it has no latency...I like that...very straightforward. But, is that a 100Mbps hub vs. a switch running store and forward or what??? As you can see some questions from 3rd party exam study guides are extremely vague. My advice is go with the answer given and stay out of the rabbit holes as much as possible.
