Tonight I took and passed the exam to become Salesforce Certified Sharing and Visibility Designer. This is one of the two missing certifications on my track to become a Salesforce Certified Application Architect. Very happy I passed and must say that it is among the hardest Salesforce certifications I’ve taken so far.
Not necessarily because of the topic but more because the questions asked are very long and very hard to decipher at times. Many questions seems to test your ability to read and understand English more than your ability to grasp sharing and visibility topics. Also for many of the questions you need to select 2 or 3 answers instead of the single radio-button answer of many other certifications.
