Exam Certified Platform Developer II topic 1 question 56 discussion

I think B is correct answer because only has "dynamic visualforce binding", not "dynamic schema binding". https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_dynamic_vf.htm

But they talking about getting the list of fields to display a multi select list for them to select so B would be right

C is the correct answer. https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_dynamic_vf.htm

C is the correct answer. https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_dynamic_vf.htm

C is correct. Question asked "Apex code". Dynamic schema binding allows developers to write Apex code that dynamically references custom or standard Salesforce objects, fields, and relationships based on user selections or dynamic criteria. In this case, the users want to pick the five fields to use as filter fields when they run the page. With dynamic schema binding, the Apex code can read the user selections and dynamically construct a query that includes the selected fields as filter criteria.

B. They use it to give the user the choice, which fields he wants to filter on. SOSL can be used as well and can be limited to one SObject, but the search cannot be adjusted to specific fields.

I honestly would throw this question out. It would be better to use dynamic SOQL, not SOSL, because we are searching a single object. I don't see B being relavent as describeSobjects() provides a list of describe results for, generally, a list of sObjects. Again, we are only interested in one. D is irrelavent as the information is already in the org. C doesn't seem to be a thing, so unless there is a typo here and should be simplified to 'dynamic apex', then C is wrong as well.

B seems to be correct as requirement is to dynamically select the fields at run time, which we can achieve with describeSObjects() by fetching all fields. Option A says SOSL queries, rather than dynamic SOSL.

Why not A it is clear that user needs to search via SOSL fields (5)? https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_dynamic_sosl.htm

I think they talking about getting the list of fields to display a multi select list for them to select so B would be right

It should be C.
