Well folks, last week at Partner Exchange 2011 marked the final sessions of the VCDX3 version of the defenses. \u00a0We now move onto VCDX4 in 2011 for those of you who are looking into this highest level of VMware certification I wanted to provide a little input. \u00a0First off I was amazed in a vCloud design workshop when asked who was planning on taking the certification how many hands went up. \u00a0What made it surprising is we also conducted two VCDX preparation workshops last Monday and the attendance was not even close to the number of people who “planned” on going through the process. \u00a0This got me thinking that people out there assume the defense is an easy thing to get through, otherwise why would so many people not come to the prep workshops? \u00a0It sounds like a silly question, but really why were more people not in the prep classes then?<\/p>\n

So here is my advise to those that are planning on taking the defense for VCDX4.<\/p>\n

    \n
  1. Review the workshop materials that are posted on the VCDX site<\/a> along with the new materials and FAQ’s as they get posted. \u00a0The information is very useful.<\/li>\n
  2. Carefully review your design and know it cold. \u00a0Referring to documents during the session only kills time on the clock, and time does fly when you are having fun \ud83d\ude42<\/li>\n
  3. Read Duncan Epping’s post<\/a> about using the template materials. \u00a0These are yours to use but show some creativity. \u00a0If you think you can make a 2 host design interesting enough to talk about for 75 minutes……go for it but think before you decide to go that route, because trust me when I tell you……it’s not going to be fun to talk about for that long.<\/li>\n
  4. When it comes to the live scenarios during the defense simply remember this; Treat it like a last minute customer meeting that you got pulled into without any notice. \u00a0You have to think on your feet and move yourself forward through the process.<\/li>\n
  5. If you are doing a fictitious design, try to use your peers to \u00a0play the customer. \u00a0Get them to set forth some real constraints, assumptions, and requirements. \u00a0Let someone else feed you these items so you can then come up with a design that fits those and present it back to them. \u00a0I know if I tried to do something completely fictitious on my own I would have trouble coming up with requirements, constraints, and assumptions, that “felt” real enough to work up a design from.<\/li>\n
  6. Establish a peer program to facilitate the review process internally and prep each other. \u00a0Peer reviews can in some case be no different than the defense itself. \u00a0Justify the design submission to your colleagues either before or after the acceptance of the design. \u00a0This is something you should workshop yourselves to help candidates prepare for the defense. \u00a0Ask each other questions about the design, remember the design should be as good in quality as you would give to a real customer.<\/li>\n
  7. Another point to make is your design does NOT have to be free of mistakes. Mine was not in my defense, but you have to understand the flaws in your design and properly address them to the panel members. Really the point is nothing is perfect. People like to think their work is perfect but nobody\u2019s is, and no DESIGN is perfect. They all may have one flaw or another.<\/li>\n
  8. Make sure you focus on the core infrastructure. \u00a0You will see this in the prep slide decks as well on the VCDX website. \u00a0Although you can submit a design on View, SRM, or even vCloud for that matter, the focus of the program is to evaluate the foundational design of the core products. \u00a0Nothing can survive without vSphere underneath it which is why the focus is generally on the core foundation design. \u00a0No building can survive without a good foundation before you start building the other floors, and neither can other VMware products. \u00a0They all need a solid vSphere foundation under them first.<\/li>\n
  9. Lastly, next time we are holding a VCDX prep workshop, if you are planning to defend……SIGN UP FOR THE CLASS. \u00a0I’m confident you will pick up other tips to help you prepare. \u00a0Don’t just assume it will be an easy process to complete. \u00a0These are usually held at VMware events so keep your eye out the next time and if you see one, sign up. \u00a0It is your chance to ask questions of real live talking VCDX Panelists since usually we conduct the class.<\/li>\n<\/ol>\n

    At the end of the day remember that it is about justification as well as tying your requirements, constraints, and assumptions to the design. I cannot count how many times I have seen VCDX applications where the design decision was \u201cTo use DRS or not to use DRS\u201d. \u00a0Although this is a valid question let\u2019s be realistic\u2026..give me a darn good reason why you would not and make that a constraint of the design which would be an interesting talking point. However if it is just because it is a best practice, then that is not very interesting.<\/p>\n

    A better example may be a constraint by the customer that their CMDB requires the application\/VM be tied to a Hostname not a cluster therefore DRS needs to be disabled. THAT is a good example of a constraint adding a requirement to the DRS design because it directly affects DRS OR having DRS in fully automated and the type of real considerations an Architect needs to address. That also affects the operational procedures for host downtime and maintenance procedures.<\/p>\n

    Nothing I have stated here is a magic formula to pass the defense which I think is what some people are looking for. \u00a0Much of this to me is common sense, and really is stuff every good Architect should know. \u00a0I have not revealed anything hidden or violated the “Magician’s Code” in any way, and there is no “Holy Grail” of how to pass. \u00a0This is really about being yourself and allowing the panel to see what you know about VMware architecture.<\/p>\n

    Below is the table that outlines the process from the VMware website which I am sure many people have seen. \u00a0I wanted to add this mainly for those that did pass the previous VCDX3 exams but never made it to a defense. \u00a0You still have to take and pass the VCAP-DCD exam to be considered for defending VCDX4 in front of a panel. \u00a0This was a common question we got last week during the prep workshops.<\/p>\n
