A company is migrating 100 TB of on-premises file shares to Cloud Storage. The network bandwidth is limited to 100 Mbps and the migration must complete within 2 weeks. Which TWO services should they consider? (Choose 2)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Transfer Appliance
Transfer Appliance is ideal for large data volumes with limited bandwidth as it physically ships the data. Storage Transfer Service can handle the final synchronization from a temporary staging location. Migrate for Compute Engine is for VM migration, not file data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
