This is VMware’s new approach for developing new training material / courses. Course material will be developed with the help of the Subject Matter Experts within the company. I was [...]

After the VCDX defenses last week in Munich and the defense sessions we had during VMware PEX I want to stress the following from my VCDX Defense blog article: Next two are role-play based.
