In this task you're going to choose, check the availability of and (hopefully) register a domain name that you'll use for your portfolio.    The technicalities of this task will take about an hour, but you may end up spending more than this. You're going be spending money on your domain name, so spend as much time as you need selecting the right one. Don't rush into it because you can't get refunds on domain names and wasting money isn't cool.
