    Hi all
    I have been applying for entry level vacancies (1st line etc) for a few weeks now and I have an interview lined up for tomorrow.
    I have been told to expect technical questions regarding TCP/IP and networking. Also, examples of common questions and what I would suggest as a fix.
    Has anyone got any idea as to what questions may be asked and what the most common questions would be so I can think about a fix? This will be my 1st support role and I really want the job!
    Any help appreciated!
    Thanks

    Very difficult to say but if your studying the A+ and it's entry level job then things they ask are likely to be covered in the A+ study material.

    I would of thought they would ask you questions on joining a PC to the domain, setting up a network printers. Troubleshooting a PC that can't get network connectivity. How to find an IP address etc. As long as you know your stuff you should be fine...:D

    Some command line troubleshooting might help, such as ping and ipconfig. Also you should know what a 169 IP address means.

    This should help you troubleshoot connectivity problems before escalating it (if needed) to second line.

    thanks for your help.
    So stuff like ipconfig, tracert, arp, route etc would help do you think?
    It's a broadband company that supplies to businesses, new developments etc and they're looking for support/helpdesk people. Never worked in that area before so I don't really know what kind of support would be needed.
    I have basic network knowledge and my CV states this so hopefully they won't be expecting too much!

    Yup, you may need to get someone to test connectivity. This can be pinging the default gateway or something like that.

    Not to point out the obvious but concentrate on network issue questions and fault finding a PC that won't connect to the internet and the stages you would go though to troubleshhot the problem. Start with the simplest things like are the cables plugged in, is the modem switched on, can they get an IP address (not a 169 address) etc. These are what I would probably expect them to ask as they would want to know if you have the sense and knowledge to take a problem and successfully know how to resolve it through the correct steps.

    As Sparky has said make sure you know all the basic command line tools like ping and tracert and what they do and this will more than likely ask about them and again as Sparky says make sure you know what a 169 address (APIPA) is and they will probably ask you what a PC with a 169 address means.

    When you say 'can they get an IP address' - what exactly do you mean?

    No IP address basically means there is a connectivity problems somewhere or there is an issue with the DHCP server or whatever network device is configured for DHCP.

    Look into the following tools and how to use them

    IPCONFIG (with all its switches) ie /renew /release /flushdns /registerdns
    PING
    TRACERT
    PATHPING

    you can also checkout nslookup, but thats more DNS than basic tcp/ip

    The may ask you questions about how data is transmitted and how it knows where to go. i.e MAC addresses frames etc which is all network+ material but if your just onto the A+ then they might not.

    You might be asked to id a mac address or to know what an IPv4 address is.
