For #CCNA prep, we get used to a two-step process: change the configuration and use the copy run start command to save the configuration. However, what happens when you interleave some less-used [...]

Configuration file management can be simple – but have you mastered all the command? This next question attempts to make you stretch a bit even for what at first may seem like a straightforward topic.

Go fast. Faster. Fastest! Sure, you need to be able to do subnetting tasks with speed on the CCNA R&S exams. But you can do some activities when studying that can reduce much of the fear [...]

To learn subnetting more efficiently, and be better prepared for the exam, you need a metaphorical push out of the nest from momma bird. That’s learning stage 2. Today’s post goes beyond the [...]

Want amazing results with subnetting on your #CCNA exam? What helps you achieve those results? To get the best results for the time invested, adjust how you study based on your current knowledge [...]

IPv4 subnetting sits at the top of the list of challenges for #CCNA. I’m wrapping up the development of a new subnetting course, and as a result, I’ve been thinking a lot about how people learn [...]

Use this practice drill for #ICND2 or #CCNA IPv6 practice. Short and sweet: look to the earlier post with 10 practice problems, and today’s post for the answers. The goal: to get good, and to go [...]

Looking for short #ICND2 or #CCNA review tasks? This new practice drill can help. The short version: take a 32-digit hex IPv6 address, and find the shortest abbreviation – or do the opposite. The [...]

Short and icky sweet: this post lists answers for the icky EUI-64 drill 1 for #ICND2 and #CCNA. The problems require you to find the IPv6 address a host or router would use, given a prefix, MAC [...]

This post starts a new type of review post for #ICND2 or #CCNA: the icky EUI-64 drill. It’s icky for two reasons: it requires you to think in binary, and it rhymes. The goal: Starting with a MAC [...]

Can you configure an IOS DHCP server from memory? Set up the DHCP pools, configure the correct subnet and mask, define the default gateway and DNS addresses, and exclude IP addresses as needed? [...]

Today’s sample question gives you a chance to test yourself to find out if you already know a few of the points made in one of the Common Mistake videos in the CCENT Exam Prep LiveLessons video [...]

This post lists the answers to summary route drill 3. If you’ve not tried the problems for this drill yet, go back, check it out, and come up with the best summary routes. Then come back here and [...]

Like the other summary route drills, this post lists three practice problems. Each problem lists a set of subnet/mask pair for existing routes in some router. Your job: choose the subnet/mask [...]

As usual, the “answers” post only makes sense after reading the “question” post. Use the question as a place to practice and ignore the speed and time pressure, or use it truly as a speed test. [...]

It’s time for the last #CCENT VLSM speed test for a while. Your job: any way you know how, derive the subnet IDs, and the range of addresses in each subnet, and then compare the subnets to [...]

It’s subnetting Friday – #CCENT edition. Your job? Look at a set of 5 or 6 subnet/mask combos, and identify which ones overlap, and which ones do not. There may be no overlaps, or there may [...]

#CCENT and #CCNA testing, as well as real-life network engineering, requires that we find configuration and design errors in the network. Problems can occur when the design and configuration of [...]

As with all these #CCNA config museum pieces, the goal is to let you select some practice exercises to get in more reps and make configuration automatic.  Today’s post shows the answers; useful [...]

Let’s now do another quick #CCENT and #CCNA practice: Add OSPF configuration, single area. Simple rules, quick review. It uses the same design as in another recent config museum piece as [...]
