Now I want to go for CCNP exam.. Please help…

Next stop CCNP

all ports are in vlan 2 = 1 broadcast domain

then there is a new vlan created, let’s say vlan 22

now we have two vlans = vlan 2 + vlan 22 = 2 broadcast domains

I don’t why I was thinking that the new switch ports are added to the same vlan, silly me

use ACL will do

If you add Ports in existed
Vlan then it will not make broadcast domain. It is making new vlan, so Vlan = Broadcast domain.

http://www.ciscopress.com/articles/article.asp?p=29803&seqNum=3

the native VLAN must match on both sides of the trunk link for 802.1Q;
***** otherwise the link will not work.

If there is a native VLAN mismatch, Spanning Tree Protocol (STP) places the port in a port VLAN ID (PVID) inconsistent state and will not forward on the link.

Cisco Discovery Protocol (CDP) version 2 passes native VLAN information between Cisco switches. If you have a native VLAN mismatch, you will see CDP error messages on the console output.

On a Trunk – Native Vlan traffic goes as UNTAGGED & both vlan 10 & vlan 1 will be connected which should not be happen.

Even though DOT 1Q identify as a native vlan mismatch, CDP need to be there & it should be a Cisco device.

B. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.
C. A native VLAN mismatch error message will appear.

Correct answer should be B.

A native VLAN mismatch error message will appear, only if the CDP is enabled on both Switches that is not mentioned on the Question.

why option B is not included in answer
while same was chosen in Q7 answer.(D. VLANs enhance network security)

B. VLANs utilize packet filtering to enhance network security.

cab anybdy clear the doubt??

Today I have passed the CCNA. (860/825)
50 questions 3 labs (VTP, EIGRP, ACL). 35 from 9tut.

Also thanks a lot Brar and Sekhar (still valid from examcollection)

Ty again 9tut

from here Q 1

Why is this not a correct option since vlans break up broadcast domain and should therefore filter out packets not meant for the network of that particular vlan?

in a switch, each port is its own collision domain. so in a 24-port switch assigned to 2 vlans (vlan 1 included), it will generate 2 broadcast domains but the collision domain will still remain to 24 (assuming all ports are connected to a host)

i think answer should be BEF instead of AEF. because vlan simply devides broadcast domain do not establish it.

I wish to pass it
Pray for me pls

Mmmm if you say that, why in the Q8 the opcion “A” isn’t correct??

thanks!

When using VLAN the number and size of collision domains remain the same -> A is not correct.

ABOUT MY EXAM:
I had total of 50 questions….
Had three simulations….ACL2, same as here at 9tut but modified as the third table of modifications above and i was dealing with host B plus different IP addresses, EIGRP almost the same as here, had to change the AS in router Home 2 from somethng 21 to 221 and add the appropriate networks also i had to delete and add some networks from router Home 1 (central router) and finaly the VTP…same as here just different question to follow the same procedures in resolving
NB: i ddnt see anythng that i had not come across before

for any other enquiries find me at ropamson@gmail.com …..best of luck for everybody working on CCNA

B. VLANs utilize packet filtering to enhance network security

Sitches filter packets based on the vlan id, which is one of the main goals of vlans – to improve security. Not sure about this question.

Vlans certainly don’t simplify adding, moving or changing hosts. If there was only one vlan in a network, this would be much simpler, so they make it more complicated.
