IT Tests

Typically, a small environment like this would only use one public IP address.

They should have a firewall/router connected to the Internet, and the internal network behind it will use an RFC1918 private address range. (10.0.0.0, 172.16.0.0, 192.168.0.0)

Each connected device will still require an IP address in the private range, but all traffic to the Internet will be network address translated (NAT'd).

Thanks,I typed the NAT commands on Cisco software at school before.I wish I could know what network problems the school would test me. Where should I type the NAT commands in real life?

It depends on the brand of equipment. Some use command lines, some use web interfaces.

When I did network practical on Cisco software, I just had to double click the routers and typed the commands.

Can I have a few pieces of test advice?For example how I should prepare for it.Should I revise my school practical notes?

Yes,you are right.My router is web interface.

Do you know what product you will be tested on?

I forgot to ask them in the morning,I don't know and I am thinking of asking them now.

I saw their photos online. They are using Cannon printers and Cannon projectors to teach kids.
