This post answers the Spanning Tree question linked here. If you want to noodle the question a little longer, check out the answer to a similar question that showed three switches in a triangle. To solve this question, just use the
Here’s another Spanning Tree question, one that creates a topology in which one switch does not have a direct link to the root. What happens in this case? Note that as with this similar question, this question is meant for
This post answers the Spanning Tree question linked here. The short answer is that there are lots of right answers! What could impact the choice of root port in a triangle topology? All port costs except the root switch’s ports’
Here’s a new CCNA-level question to consider, this time on Spanning Tree Protocol. Before diving in, be warned, it’s meant for study prep, not for assessment. That is, I’m not attempting to make this question exactly like an exam question,
STP questions on the #CCNA exam require that you practice the rules for choosing the root switch, root port, and designated ports. If oyu ignore some of those pesky tiebreakers, the rules can be pretty straightforward. Often times, people understand
Although most everyone has moved their #CCENT and #CCNA study to the new exams by now, I’m still working on a few more topics and questions for this Fast Start series. Today’s post on Spanning Tree Protocol (#STP) starts another
If you didn’t see the puzzle problem statement, then the answers won’t make as much sense. Especially for this one, the new post this week that gives some suggestions on how to attack these STP puzzles can help. The realization
Here’s the 2nd STP Puzzle. As with most of these drill-style practice problems, take a look at the problem statement, and work it out. No need to rush on this one – just get it right. These STP puzzles give
This post wraps up the discussion of STP Puzzle #1 with a brief look at finding the designated ports (DPs) on each link between switches. As usual, check out the original post to make sense of this one. Note that
This post looks again at STP Puzzle #1. As usual, check out the original post to make sense of this one. Part 1 of the answer determined that switch S4 is the root in this puzzle. This post walks through
