attending a network support interview, wat technical questions do they usually ask ?

anyone can give some pointers?

You are experiencing intermittent issues relating to congestion with your network. What are the possible causes of congestion on a LAN?

just an example

What's a packet collision and how do you fix it?

OMG, then wat are the answers of both those questions you guys posted?

fast fast tell me, need go out d loh,

how many layer hv? wat layer doing wat function? can you come if urgent problem happen in midnight

their question is too simple
both quesions required a switch operate in full duplex to solve the collision problem!

his layer most probably refer to osi. total 7 layers. Application, Presentation, Session, Transport, Network, Data Link and Physical!

FOr my question, it's low bandwidth,boardcast storms as well as too many hosts in a boardcast domain..
