CCNA Frequently Asked Questions

50 posts in this topic

Hello everybody. I ask maybe trivial easy question but I don't find a good answer for it:

Why we use VLAN ? Why? Why we cannot use ONLY IP-subnetting? When did appear REAL necessity for VLAN?

I read that we use VLAN for security, logical separation of users, separation one apartment's trafic from another apartment's trafic, inrcreasing number of broadcast domains, decreasing useless broadcast trafic and blablabla...

I feel that it isn't prime cause why human uses VLAN.

 

Please, give me the real examples when using of VLAN is very necessary and we cannot do without VLAN's help or it will cause big difficulties?

 

As I know VLAN was ISP's technology initially and only then VLAN has been used for small LANs.

 

Thanks

What is the proper order of the layers of the OSI model from the highest layer to the lowest layer?

· physical, network, application, data link, presentation, session, transport

· application, physical, session, transport, network, data link, presentation

· application, presentation, physical, session, data link, transport, network

· application, presentation, session, transport, network, data link, physical

· presentation, data link, session, transport, network, physical, application

 

as I know: application, presentation, session, transport, network, data link, physical

If your certification is expired, you have to start from CCNA again. that's the only way. By the way CCNA exam is little bit expensive on these days and it's about $295.http://www.pearsonvue.com/vouchers/pricelist/cisco.asp.

 

You can get latest CISCO certification and news from following page

Alright if you have to know, its pretty vague to define what "Finger request" is, mainly it is used in linux. It has been used as a hacker tool for ages. When it comes to Cisco, it has the same effect.

 

So what is a "finger" in respect to Cisco:

 

The finger service can allow remote users to find out who is logged into the router, providing information like login names and such. The "no service finger" command disables the router from replying to finger requests, but it doesn't block the requests from coming into your networks, you would need an ACL to block them completely.

Your answer is concise and professional, thank you very much!
