CCDE Topic: docs I found useful Step One: the written (read this even if you already passed!) I found the written outline to be the most useful preparation not only for the written exam, but also the practical. I went through all of the topics outlined and made sure I understood exactly what they wereContinue reading “CCDE Topic: docs I found useful”

CCDE certified, now what?
So it’s been a few weeks since learning that I passed the practical, and other than NOT having to attend the next practical in December, not much has changed. I think the marketplace is still trying to determine the value of this certification, and my feeling is that some employers may think it’s nothing moreContinue reading “CCDE certified, now what?”
CCDE 20090006
Yesterday I received the letter from VUE confirming my pass of the CCDE practical exam: 352-011. I am now CCDE #20090010. At least according to VUE – the Cisco site is still not updated with a number. Correction: the Cisco site was updated with a number (20090006). The results were mailed on 11/13/2009 so it’sContinue reading “CCDE 20090006”
What is the issue with re-marking and OoO packets?
This question, taken from the CCDE Written Outline, taught me something new. Since that’s the purpose of any certification, I welcome these interesting, if somewhat vague, questions. The main issue with re-marking and Out-of-Order packets can be found in RFC3819: (aka BCP89) “reordering does come at a cost with TCP as it is currently defined.Continue reading “What is the issue with re-marking and OoO packets?”
I failed the CCDE… now what?
I checked the online certifications tracking tool and found out that I have failed my first attempt at the CCDE. What does this mean to me, and what am I going to do about it now? I’ve already registered to sit for the next practical exam in August (Chicago, IL). This leaves me with roughlyContinue reading “I failed the CCDE… now what?”
Update
Nothing yet from the CCDE team. It’s only been 8 weeks.
IS-IS, MPLS-TE, and wide metrics
I came across an interesting topic in the book Traffic Engineering with MPLS yesterday. The topic involves migration from narrow to wide metrics. As you know, wide metrics are required to support MPLS TE, so if you have a network that is currently deployed with narrow metrics (the default) you will have to migrate toContinue reading “IS-IS, MPLS-TE, and wide metrics”
Took the CCDE Practical Exam Today
14 people in Chicago and 14 people in London took the test today. First impressions: 1. It’s very, very difficult2. I don’t think it’s “impossible” However, I will caveat this with – I don’t really think I have a chance at passing. In all, I had fun taking it. I’m mostly relieved to have hadContinue reading “Took the CCDE Practical Exam Today”
CCDE Written Outline Topic 4 : Logging Config Changes
For “Identify best practices for configuration management (i.e. logging config changes, auditing “as running” vs “as configured,” consistent feature application, etc.)” I found some information in the IOS Configuration Fundamentals Configuration Guide. Specifically, how to configure logging of config changes.
New Cisco Forum
Cisco has recently introduced a new collaboration site: Cisco Learning Network It looks like it will be pretty helpful to those of us preparing for the CCDE.
