Exam 200-901 topic 1 question 250 discussion

A and B

A: is correct B: is correct: they refer to the three traffic types: 1. Uni-cast 2. Multi-cast 3. Broad-cast Multi-cast and Broad-cast domains are limited by the router but not uni-cast (by default). But the rest of the answers are less correct so I would pick answer B. C: Not correct: If they divide the current network into two pieces they will have less host addresses ( two addresses will be assigned to the network and broadcast address) D: Not correct: A router does not bridge any traffic, it routes traffic. E. Not correct: Dividing the network into two pieces will not limit the router from forwarding packets to the internet.

i don't who need to hear this but subnetting doesn't provide more addresses rather it's the opposite

Fully agree with mickedu explanation.

a AND c

Splitting a network into separate client and server subnets can have several benefits. One reason to do so is to use a router to limit the types of traffic that can flow between the clients and servers. This can help to improve network security by restricting access to certain types of resources or services. Additionally, subnets can provide more IP address space for clients and servers, which can be particularly useful in larger networks where there may be a limited number of available IP addresses.

A and B make sense. D is incorrect. It understand by bridge those devices that conect LANs along time ago. Now routers replace all those funtions, conecting networks mean routing and limiting the trafficc in broadcast domain. This questions is trick

Weird choice of answers. Only A I know is correct

I'm guessing whoever wrote this question is not a network engineer. This sort of question puts me off of doing cisco certs. A and B

whoever wrote this question needs to be slapped. A - the only answer that is obviously correct. B - poorly worded. a router could limit traffic if configured with ACL's. but traffic wouldn't be blocked by default. C - is vague and seems irrelevant here as there no mention of what size subnets would be configured. subnets don't implicitly provide more addresses. a /24 or two /25's give you the same usable IP space. i don't see how C can be a correct answer. D - appears incorrect and refers to what a switch would provide. E - poorly worded again. without knowing more about the router config internet access to the server subnet wouldn't implicitly be blocked. just as it wouldn't for the client subnet. i truly have no idea what the second correct choice is here.

I'm going with AC. So let's say you have a /26 network for both your clients and your servers. That's the smallest network that would support both groups in one subnet, and that would be 62 IP addresses. Let's make a /29 for the servers, which would give you 6 IPs, and another subnet for the clients. Because you need space for 50 clients, the smallest subnet for the clients is still a /26. So 6 + 62 is greater than 62 by itself, so C is a viable answer. B is wrong as it limits traffic volume, more than type D is a layer 2 function E is a firewall function, and an ACL on a router isn't mentioned

It's A & C Subnets DO provide more addresses because they are not all on the same network A router "ROUTES" between subnets. Bridging is layer two https://en.wikipedia.org/wiki/Bridging_(networking)#:~:text=A%20network%20bridge%20is%20a,Bridging%20is%20distinct%20from%20routing.&text=In%20the%20OSI%20model%2C%20bridging,link%20layer%20(layer%202).

A & D should be OK

not C , due the fact that subneting is lossing address space (less space for the hosts)

I would go with A and C

I don't agree with E. I think it should be AB. A router does not deny internet traffic implicitly. It could, but therefore there is not enough information for in this example. A Firewall would be a more logic answer for denying traffic

answer: A, E
