Exam Certified Business Analyst topic 1 question 105 discussion

While user adoption and system downtime are also important considerations, scalability addresses the fundamental challenge posed by growth and is crucial in ensuring that the security architecture supports the organization's expansion smoothly and efficiently.

I dont think user adoption should be a factor here because users arent working with the ins and outs of the security system setup, it will just be running in the background while they work Scalability makes the most sense as its specified that as your company grows your org grows with it, if you've only built for say 100 customers and next year you serve 10,000 you'll bottleneck your system. Question states they're going to significantly grow their workforce so B makes the most sense https://trailhead.salesforce.com/content/learn/modules/scalability-with-salesforce/understand-scalability-at-salesforce

A complex OWD and dozens of user profiles. BA should focus in 1st instance on scalability.

Complex solution implemented must be based on NTO's complex requirement. Rather than re-inventing the whole security solution, it will be better to device a solution keeping the existing security solution as base and hence the 'User Adoption' is quite important while thinking for any further solution.

When it comes to security solutions for Sales Cloud, there are many aspects to consider. However, the most important aspect for a business analyst (BA) to consider when recommending a solution is scalability. This is because NTO plans to significantly grow its workforce and the security solution must be able to accommodate this growth .

I believe it would be scalability

Why would BA consider User Adoptions because of Sharing Rules and Org-Wide Default? Why wouldn't he consider Scalability?
