Please select only the non-functional requirements that Charming Waters asks you to implement.

B.The portal content should comply with the latest travel industry regulations
C.Every morning the sales manager should receive a sales report with the previous day results
D.The portal authentication should be based on the OAuth2 protocol only
E.The mobile app initial load should take not more than 1.5 seconds
F.Before purchasing a cruise, the customers should contact the sales team directly using the portal’s Contact form.

Correct Answers: B and E 
The project requirements are divided into two groups: functional and non-functional. 
The functional requirements define what the system should do and behave like if you push the save button, the system saves the document. The non-functional requirements describe the system`s properties that support system behavior, like saving the document should not take more than 3 seconds on average. 
The typical non-functional requirements include regulatory, compliance, privacy, performance specifications, recovery time, availability, etc. Option B is correct because the requirement for portal content compliance is a non-functional requirement.
Option E is correct because the requirement for mobile app initial load should take not more than 1.5 seconds is a performance non-functional requirement.
Option A is incorrect because the offline capabilities of the mobile app are the app`s behavior functional requirement.
Option C is incorrect because the report generation and delivery is the system behavior functional requirement.
Option D is incorrect because the requirement for the OAuth2 authentication is the portal functional requirement.
Option F is incorrect because the requirement to direct the Contact form content from the prospective clients to the sales team is the portal functional requirement.
