Salesforce Certified Technical Architect - Multiple Choice

After a long time since I attempted Salesforce Certified Technical Architect - Self-Evaluation (SP13) in January 2017 I finally got a chance to appear in the Salesforce Certified Technical Architect - Multiple Choice (WI17) exam. I would say this is the hardest exam so far I have given after Salesforce Certified Advanced Developer [DEV 501] - Multiple Choice exam because you need to read lots of content (60 long scenario-based-questions) within 120 minutes. So, you can't spend too long time on one question.

In 2016 at Dreamforce, Salesforce introduced the Salesforce Architect Journey, a new framework that provides a step-by-step approach for the CTA journey. All candidates who have already started the CTA path prior to the 2016 Dreamforce announcement, they can continue the existing program. However, they would have deadlines to complete all 3 steps to be awarded the Salesforce Certified Technical Architect credential!

Deadlines for the existing CTA program:
  • Step 2: Multiple-choice Exam = January 31, 2017 (After passing this, you will have two years from your exam pass date to complete your review board presentation)
  • Step 3: Review Board Presentation = January 31, 2019
If you will not pass by the specified deadline, then you will need to follow the new Architect Journey to complete your Certified Technical Architect credential. Please read further here.

The Multiple Choice exam has divided into high level categories:
  • General Architecture Concepts [10%]    
  • Platform Architecture Concepts [25%]    
  • Security [17%]    
  • Application Design Patterns [20%]    
  • Integration Patterns and Best Practices [15%]    
  • Development Lifecycle and Deployment Planning [12%]    
  • Communication [1%]
This is my experience and would recommend to read before appear in the exam.
