- A
Proximity to your user base to minimize network latency.
Closer regions reduce round-trip time.
- B
Availability of the specific Google Cloud services required by the application.
Not all services are in all regions.
- C
Pricing differences between regions due to variations in compute and storage costs.
Why wrong: Cost is a factor but not among the top three when low latency is critical.
- D
Compliance with data residency requirements (e.g., GDPR, CCPA).
Data must stay within specific geographic boundaries.
- E
Number of zones in the region to ensure high availability.
Why wrong: Most regions have three zones; difference is minimal.

Google PCA Manage implementation of cloud architecture Practice Question
This PCA practice question tests your understanding of manage implementation of cloud architecture. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 choosing a Google Cloud region for deploying a low-latency application serving global users? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Proximity to your user base to minimize network latency.
Option A is correct because deploying in a Google Cloud region geographically close to your user base minimizes network latency, which is critical for low-latency applications. Google Cloud's global network uses edge points of presence (PoPs) and premium tier routing to reduce round-trip time (RTT), but the physical distance between the region and users still directly impacts latency due to the speed of light and fiber optic propagation delays.
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
This exam often tests the misconception that high availability (zones) is equivalent to low latency for global users, but zones only provide redundancy within a region, not reduced network distance for geographically distributed users.
Detailed technical explanation
How to think about this question
Under the hood, Google Cloud's global network uses BGP anycast for Cloud Load Balancing, directing users to the nearest healthy backend region based on latency and capacity. For ultra-low latency, consider using Premium Tier networking, which routes traffic over Google's private fiber backbone rather than the public internet, reducing hop count and jitter. A real-world scenario is a real-time multiplayer game where even a 50ms latency increase can degrade user experience, making region selection critical.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
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 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.
