Just spent the better part of the day moving this site, along with a handful of others that share the same WordPress multisite install, from Softlayer to DigitalOcean.
And so far, so good. I tried a couple of page speed reports before and after the move and they all showed a quicker response. Nothing negative against Softlayer. I’ve been with them for many years, and that may be part of the issue that I was on a relatively out of date dedicated box. It also was running cPanel, and now I’m not so that could be at play as well.
The goal is to move from the roughly $200 a month I was spending on Softlayer to no more than $30 or $40 a month with DigitalOcean droplets. The $200 was way more than I needed for the sites I’m running, so I think a goal of $40 is pretty realistic.
I may put up a review at some point, but for now I’ve not been online with DigitalOcean long enough to have a valid opinion.
Okay, and now back to the quizzes…
This quiz is for subnet practice and allows you to practice identifying network and broadcast addresses given an IP address and netmask.
This quiz is for practicing with subnets using all netmasks and CIDRs. It’s meant for practicing for the Cisco CCNA exam and is part of the Cisco Exploration and the second semester of the Discovery curriculum.
If you would rather practice with a more classful approach using only the /8, /16, and /24 subnets there is another quiz here that you can try.
This quiz allows you to practice identifying network and broadcast addresses given an IP address and netmask.
This particular quiz is for simple addresses where the netmask only contains either a 0 or 255 in each octet. It is intended to match up with network addressing in the first semester of the Cisco Discovery CCNA curriculum. Continue reading
This is the first of what should be a collection of quizzes where you can match networking elements to their corresponding OSI layers. This particular quiz is 10 questions, but there are enough pieces to networking that there could potentially be dozens of quizzes like this.
Here’s a quick 9 question quiz to check how well you know your networking acronyms.
Computer geeks love their acronyms.
This quiz asks you to match acronyms with the OSI layer that they occur on. You don’t necessarily need to know what each acronym stands for, but it wouldn’t hurt.
OSI, or Open Systems Interconnection, layers are used to separate how traffic moves between computers. By using these layers network techs can narrow down where problems occur and save time by only troubleshooting where a potential for the problem may exist.
Catch is, the OSI model is a difficult concept for many learning networking for the first time. Below is a short 10 question quiz covering the basics of the OSI model.
Note that some of the questions may have multiple correct answers. Be sure to select all that apply.
