Correct answer & explanation
✓
Purchase Microsoft 365 Business Basic licenses
Microsoft 365 Business Basic is the most cost-effective option for temporary contractors needing only email (Exchange Online) and Teams, as it provides these core services at the lowest per-user price. It is designed for small and medium businesses (up to 300 users) and includes web and mobile versions of Office apps, which are sufficient for basic communication needs. F3, E3, and E5 licenses include additional features (e.g., desktop Office apps, advanced security, compliance) that are unnecessary for short-term contractors, making them more expensive.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose F3 thinking it is the cheapest option for temporary workers, but they overlook that Business Basic is actually lower cost and sufficient for basic email and Teams, while F3 is designed for shift workers with specific frontline scenarios and includes extra features that increase price.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft 365 Business Basic provides Exchange Online Plan 1 (50 GB mailbox) and Microsoft Teams with standard messaging and meeting capabilities, but no desktop Office apps—users must use the web versions. This licensing tier is ideal for scenarios where users only need communication tools and can access Office via a browser, avoiding the cost of full Office ProPlus subscriptions. In a real-world scenario, if contractors later require desktop Office, you could upgrade individual users to Business Standard without changing the entire tenant plan.

Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
