@All,
Last Monday (6th April), I appeared for VCAP5-DCD (VDCD550) and passed the exam. Even though I din't score high, but relieved with a passing score, anyway pass is a pass.
Thanks for all esp Jason (virtualtiers) who pointed me in right direction.
How I Prepared:-
1. Know your Risks, Constraints and Assumption
2. Know your Conceptual, Logical and Physical Design
3. Functional and Non-Functional Requirements
4. All vSphere Products and vSphere cluster settings.
