You take a new #CCENT or #CCNA practice exam, and see a few questions about IPv6 addresses. You focused on the basic format – how to abbreviate, how to expand, and what the prefix length means. Then the practice exam asks you something about which address is in which category, or what it’s used for normally, and all you see is the hexadecimal address – so you draw a blank. Today’s post poses an ICND1 level IPv6 addressing question that makes you think about the usage of an IPv6 address, based on the address value itself, taking the discussion a bit beyond just how to decipher the numbers.

IPv6 was formerly in the ICND2 side of #CCNA, but now it’s in the ICND1/#CCENT side. ICND1 includes more than a few IPv6 topics, but the first and often most intimidating topic is the most basic feature: IPv6 addressing. Today’s post introduces the topic, with question and answer posts to follow.

ROAS is on the new ICND1 and CCNA exams. Check. The previous post posed a question about ROAS. Check. Today’s post wraps the topic, showing the answer. Check out the question before flipping the page!

The new #CCENT and #CCNA exam topics state that we need to be ready to configure and verify Router on a Stick (ROAS), including encapsulation and subinterfaces. Today’s post poses a question that requires those skills. This post asks the question, with the next post listing the answer. Enjoy!

To help get you started with the new #CCENT and #CCNA exams, I’ve planned a series of blog posts on some of the new and more prominent exam topics for the new exams. By now, anyone beginning CCENT or CCNA study should be headed for the new exams. This series will explore several of the new topics, and topics that now have more emphasis, to help you get off to a great start with the new exams.

Today’s topic: ROAS. Cool acronym, and was in #CCNA in the old days (before the March 2013 changes), but it gets a little more focus in the new exams. Today’s post hits the highlights of Router on a Stick, now squarely in the ICND1 and CCENT part of the Cisco cert equation.

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 on troubleshooting. Today’s post gives the why/wherefore on the rest of the answers I didn’t get to in answer part 1.

• Link to Question 105

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 (wrong answers) with both questions: The answers that mentioned port security.

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 symptoms as the previous question (#104 in the blog), and gives you four more possible answers. This one has at least one right answer, maybe more.  What can you rule out, and what can you rule in? I’ll get to the answers for both questions for the next post.

Today’s question turns the #CCENT discussion around, from “what happens when it works” to “what might cause it to not work”. Like the previous three questions, it mixes layers 2 and 3, this time requiring some troubleshooting analysis. The question uses the same figure as the last few questions, with the idea that one single thing is broken in the network. What can you rule out, and what can you rule in?

Today’ post gives the letter answer(s), and explains why, for this latest #CCENT question. The question focuses on ARP tables, but with enough noise to make you think about what really happens in the network. Don’t read here until you try the question!
