Hi Everybody,
i m failed in my ccna exam at first attempt and it was very bad score but i was prepared to get atleast 900(i was expecting)

. But when i attend the exam there were very hard questions and they all on topology not a single question like what are the functions of switch at layer two????? etc. they were very big questions and very hard so from where i can get those questions for practice so i can pass my exam at second attept and because of all questions so big and on topology i was running out of time.
I had two sim question one on vlan and second it was i have to configure router which is connected to other router was configured already with ip address and that configured router was dce end and my was dte end. Configured router was attached to switch and switch to pc when i finished configuration on my router i cant ping that router and even from that pc i cant ping already configured router and from pc i can only ping that router. i didnt had any permission to do anything so where i was wrong and even at last before i finish my configuration i used no shut command. and i lost that sim question plz help me here.
my score wasnt too bad but i dont want say here and i attend exam on 21st and then i took off still i m on off but i say let me go back on track slowly slowly.
