    hi Bombal, between GNS3 and cisco packet tracer, so which one do you recommend using?
    I'm using GNS3 right now and my laptop can't run the Cisco packet tracer at the same time

    I have been taking your CCNA course on your website, I booked my exam and have been doing some practice tests, most of the time I have no problem verifying why some answer is not what I thought it would be but this one sticks in my side and I wanted to know what your feeling on it is:
    The question is quite simple really:
    What command configures a switchport using the default Vlan?

    I think because all ports are in vlan 1 by default that just making it an access port is all that you need to do, and that is debatable as it is usually by default an access port anyway.

    So I said "switchport mode access", rather than "switchport access vlan 1" because the ports are in vlan 1 by default. Any other vlan, I would say "switchport access vlan X". The answer is supposed to be "switchport access vlan 1" but to me that is redundant, and unless specifically stated it is in another vlan, this would be unnecessary. Am I over-complicating this question?

    love to learn from you, David. When I try to open the TCP_IP_OSI_Model.pkt file ..I get the message that it is not compatible with my version of Packet Tracer. Are there others whith the same error?
