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 [...]

Today’ post gives the letter answer(s) to the last two #CCENT questions, and combines the discussion of the answers to both questions. It combines both in part because much of the background information applies to both. Don’t read here until you try question 104 and question 105!  Today’s post then looks at the toughest distractors [...]

When I wrote the previous #CCENT troubleshooting question, I kept coming up with some really good answers, at least good for learning those subtle points that people miss when they don’t dig into the topics deeply enough. So, I made two questions out of the same scenario. Today’s post takes the exact same scenario and [...]

Here’s another #CCENT question that makes you think about both layer 2 and 3. PC1 and PC2 successfully connect to a web server. What ARP table entries should exist at the end of that process?

A seemingly simple #CCENT question: PC1 pings an IP address. What protocols are used as a result? And does the topology matter? Today’s answers to the previous blog post’s CCENT question spells out the literal answer, and the steps. Check here for the original question before looking at the answer.

One of the tougher things to do for #CCENT is to get used to all the new acronyms and figure out how they all fit together. Today I’ll start with a somewhat basic ICND1-level #CCENT question that gives you a chance to review some of the more common protocols and related acronyms. Then I’ll build [...]

This is post 4 so far in this lab. Check out the first three posts (post 1, post 2, and post 3) for the proper background. Today’s post: some analysis of major task 1, in which you predict why the routing tables on R1, R2, and R3 look like they were shown to be in [...]

Post 1 and Post 2 in this lab essentially set us up for today’s post. Today’s post gives you three big tasks, each of which assumes the same topology, IP addresses, and routing protocol (RIP-2) shown in the first two posts. In two of the tasks, your job is to figure out the specific configuration [...]

If you can’t predict what should be in the routing tables when you know the topology and the config (as shown in lab 3 post 1), then you’re not going to be able to predict the config based on the topology and some show command output. Today’s post completes the part of the initial part [...]

Today’s post begins a new CCENT lab, but with a very specific goal: to build troubleshooting skills for the exam. A little later, I may take the time to do a whole post just on the theory behind why I think this style of lab can help you learn some troubleshooting skills. The short version [...]
