Common exam traps

The trap here is that candidates often assume remote file access requires a VPN or that video meetings need a higher-tier plan like Business Standard, overlooking that Business Basic already includes Teams and OneDrive/SharePoint mobile apps for these exact scenarios.
Detailed technical explanation
How to think about this question
Microsoft 365 Business Basic includes the web and mobile versions of Office apps, but more critically, it provides full-featured OneDrive for Business (with 1 TB storage per user) and SharePoint Online, both of which support mobile app access with offline sync capabilities. Microsoft Teams, included in Business Basic, supports video meetings with up to 300 participants, screen sharing, and mobile client functionality, making it fully suitable for the sales team's needs. The trap here is that candidates may assume mobile file access requires a VPN or that video meetings need a higher-tier plan, but Business Basic's cloud-native architecture already delivers these capabilities securely via TLS 1.2+ encryption and modern authentication protocols.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
