Wendell's CCENT Skills Blog

Wrapping up this set of five #CCENT questions today with the completion of the answers. Sorry it took a while for this last post – work went sideways unexpectedly last week. For those of you who don’t recall the flow: five related questions in the recent past, with the last two (104 and 105) focused [...]

This blog post gets back to a short series of related Config Museum pieces. This time, you get some basic IP addressing requirements. Your job: calculate the IP addresses to be used by routers and hosts, and create the router configuration for in the interfaces in the network diagram. No guile, no tricks, just a [...]

Today’s post just lists the answers to the Mask Design drill #2. The drill lists some basic requirements for a number of hosts per subnet, and a number of subnets, and a network class. Your job: Pick the one mask that meets all the requirements. Today’s post lists the answers. My ICND1 book, Chapter 16 [...]

Here’s another mask design drill, with the same idea as the previous two posts (chronologically speaking). For those of you with my ICND1 book, Chapter 16 spells out the details, and you can just use this as more practice. The first part of today’s post repeats the general instructions for the drill. It then shows [...]

Today’s post answers the five questions in a previously posted exercise. What’s it about? Someone came before us at most every company and made up an IP addressing plan. These exams test our ability to look at that plan and decipher what the plan does, including answering this question: “How many subnets does this plan [...]

Someone came before us at most every company and made up an IP addressing plan. These exams test our ability to look at that plan and decipher what the plan does, including answering this question: “How many subnets does this plan create?” “Host many hosts per subnet” This post gives you practice, plain and simple. [...]

Today’s post shows the solution to subnet design exercise 4, specifically the IP subnets. This post isn’t all that meaningful without reading the other one first – after that, and after you take a crack at creating the design yourself, dive in! Here are some useful links: The original problem statement for this problem The [...]

The subnet design exercises require that you do some subnetting math, but rather than reacting like you would in a help desk or support job role, you plan as if you were in the role of a lead network engineer. If you have seen the other subnet design exercises, you already know the drill. If [...]

This blog post simply lists the answers to the earlier Config VM from a few days ago. This post make no sense without the first one, so don’t look until you read the other post. No guile, no tricks, just a chance to exercise. The topic for this post: finding the lowest IP addresses in [...]
