PAS-C01 Migration Practice Question
Which THREE factors should be considered when selecting an AWS Region for a migration to minimize latency for users in Europe? (Choose three.)
⚠ Common exam trap
Test-takers frequently confuse Availability Zone count with latency optimization, but Availability Zones are designed for resilience within a Region, not for reducing user-facing latency.

Correct answer & explanation
✓
Data residency and compliance requirements
Data residency and compliance requirements (Option A) are critical when selecting an AWS Region for a migration to minimize latency for users in Europe because many European countries have strict data sovereignty laws (e.g., GDPR) that mandate personal data remain within the EU/EEA. Choosing a Region outside Europe would violate these regulations, regardless of latency benefits, and could result in legal penalties. Therefore, compliance directly influences which Regions are permissible, making it a primary factor in Region selection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Data residency and compliance requirements
Why this is correct
Data may need to stay in specific countries.
- ✓
Availability of required AWS services in that Region
Why this is correct
Not all services are in all Regions.
- ✓
Proximity to user base
Why this is correct
Closer regions reduce latency.
- ✗
Number of Availability Zones in the Region
Why it's wrong here
All Regions have at least 2 AZs; not a latency factor.
- ✗
Cost of data transfer between Regions
Why it's wrong here
Cost is not the primary latency factor.
