NetSim 10.5 was released today. This is primarily an update for NetSim’s routing and switching engine which adds support for Dynamic Host Configuration Protocol version 6 (DHCPv6), fixes several minor DHCP bugs, and fixes an activation issue affecting some NetSim and NetSimX (BEE) customers. Three new CCNP labs are included to cover this new technology. Five new CCNA labs are also included which offer additional Access Control Lists (ACL) practice. All eight labs are listed below:

3.3. Practice Exams 101 – Part 1
By Val Bakh
In the first two blog posts of this series, we discussed Microsoft certifications and touched upon a couple of study options. It turned out that Microsoft’s online technical libraries and product documentation are no longer suitable as primary exam preparation tools. In this blog post, we’ll explore practice exam products: what they are and how to find the ones that are worth your money and effort.
3.3.1. The Ancient Adage
“Read the manual first!” is an ancient adage that has been haunting humankind since the days when we invented printing. Seems pretty obvious, doesn’t it? And still, often times, we buy some new high-tech gizmo, bring it home, unpack it, and then immediately start pushing its buttons and playing with whatever other controls it might have. But somehow it always seems to happen that we can’t make the thing do at least some of what we expect it to do. We scratch our heads, we push more buttons, and only after exhausting our creative zeal, we recall having seen a small brochure that came with the thing: the instruction manual. We dig it out from the depths of the packaging garbage and … slap our foreheads in exasperation. It turns out it was so easy and we were pushing all the wrong buttons. It’s all right here, in black and white: press Button A and then press Button B. Next time, we swear, we will read the instructions first. But by the time we buy another toy, the promise is long forgotten and the new buttons look a lot more appealing to our itchy fingers than an unobtrusive booklet, almost lost somewhere at the bottom of the box.

A new problem has arisen in CCNA class: We have a lab that asks the students to enable a debug command; the debug overruns the console buffer to the extent that commands cannot be entered, and this goes on for more than an hour!

Like many other people who live in houses, I have a contract with a pest control company. Now and then, someone arrives at my door wearing a crisp uniform and carrying a giant canister full of some kind of magical chemical concoction. This pest controller uses a long wand that is attached to the canister to conjure up a magic invisible shield that prevents six- or eight- or hundred-legged creatures from invading my space. I know the pest control service is working and worth it when I am not confronted by any tiny crawling, flying, or undulating critters. Thus the debugger who visits my house every now and again does so because I don’t want to see any evidence of bugs in my living space.
You’re studying your Cisco technologies, preparing to run the gauntlet of certification exams that stand between you and certification. You’re feeling pretty confident in your understanding of the requisite technologies and how they work. You’re particularly confident in your grasp of Cisco’s Enhanced Interior Gateway Routing Protocol (EIGRP), but then somebody mentions something called EIGRP named mode configuration, or possibly even Named EIGRP, and suddenly you’re all like ZOINKS!?!?
