200-301 V1 Appendices

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 [...]

The answer for Overlapping VLSM Subnets Speed Test 2 are below the fold! Here’s a complete list of related posts: Intro to overlapped subnet problems All Overlapped Subnet problems IPv4 [...]

Time for another practice problem to find any overlapping IPv4 subnets. I’ve kicked this one up a notch compared to the previous exercise – this time the list (below the fold) shows IP [...]

The answer for Overlapping VLSM Subnets Speed Test 1 are below the fold! Other posts in this series: Overlapping Subnets – the Problem VLSM subnet overlap problem 1

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 [...]

This post wraps up the #CCNA Q&A focused on how routers add routes to their routing tables. What happens when a router happens to learn three separate routes for the same subnet ID – but with [...]

This latest #CCNA question takes us in the same direction as the previous question: how does a router choose between different competing routes? Today’s question adds connected routes to the mix, [...]

What happens when a router happens to learn three separate routes for the same subnet ID – but with different masks, and with different routing protocols? What should you be thinking about when [...]
