Quick Answer
The answer is proximity to user base, data residency and compliance requirements, and AWS Region service availability. Proximity to user base directly minimizes latency by reducing the physical distance data must travel between European users and the SAP system, while data residency and compliance requirements—such as GDPR—are non-negotiable in Europe, often mandating that personal data remain within the EU/EEA, which can restrict Region choice regardless of latency benefits. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to balance performance with legal constraints during an SAP migration; a common trap is to focus solely on latency metrics and overlook that a non-compliant Region is simply invalid. Remember the mnemonic “Proximity, Privacy, Provisioning” to recall that user location, data laws, and available SAP services must all align before you select a Region for European users.
This PAS-C01 practice question tests your understanding of migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE factors should be considered when selecting an AWS Region for a migration to minimize latency for users in Europe? (Choose three.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Data residency and compliance requirements
Data may need to stay in specific countries.
Availability of required AWS services in that Region
Not all services are in all Regions.
Proximity to user base
Closer regions reduce latency.
Number of Availability Zones in the Region
Why wrong: All Regions have at least 2 AZs; not a latency factor.
Cost of data transfer between Regions
Why wrong: Cost is not the primary latency factor.

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Cost of data transfer between Regions
Why it's wrong here
Cost is not the primary latency factor.
Common exam traps
The trap here is that candidates often confuse Availability Zone count with latency optimization, but Availability Zones are designed for resilience within a Region, not for reducing user-facing latency.
Detailed technical explanation
Latency is primarily governed by the speed of light and the physical distance between the user and the AWS Region; each additional 100 km adds approximately 0.5 ms of propagation delay. AWS Global Accelerator or CloudFront can further reduce latency by using edge locations, but the underlying Region selection still determines the baseline latency for services like EC2 or RDS. For users in Europe, Regions such as eu-west-1 (Ireland), eu-central-1 (Frankfurt), or eu-west-2 (London) provide the lowest latency due to their geographic proximity.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
