Quick Answer
The answer is global endpoints, because Vertex AI Global Endpoints enable multi-region serving with automatic traffic routing to the nearest region that has available capacity, which directly meets the requirement of low-latency inference for a large 10 GB model across geographically distributed users. This feature leverages a single endpoint URL that intelligently directs requests based on the client’s origin, ensuring minimal latency without requiring manual failover or load balancing. On the Google Professional Machine Learning Engineer exam, this concept tests your understanding of real-time serving architecture versus batch or private access options—a common trap is confusing global endpoints with regional endpoints or assuming private endpoints solve latency across regions. Remember that global endpoints are for global traffic distribution, not for VPC isolation or batch processing. A useful memory tip: think “global for globe-trotting traffic, regional for local latency.”
This PMLE practice question tests your understanding of serving and scaling models. 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.
An organization needs to serve a large model (10 GB) with low latency across multiple regions. Which Vertex AI feature best meets this requirement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Private endpoints
Why wrong: Private endpoints only serve traffic within a VPC, not optimized for multiple geographic regions.
Batch prediction
Why wrong: Batch prediction is for asynchronous, large-scale predictions, not real-time low latency.
Model Monitoring
Why wrong: Model Monitoring detects drift, not serving requests.
Global endpoints
Global endpoints automatically route to the closest region, providing low latency across regions.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Global endpoints
Option A is correct because Vertex AI Global Endpoints automatically route traffic to the nearest region with capacity, reducing latency for geographically distributed users. Option B is for batch jobs, not real-time. Option C is for private access within VPC, which does not address multi-region latency. Option D is for monitoring, not serving.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Private endpoints
Why it's wrong here
Private endpoints only serve traffic within a VPC, not optimized for multiple geographic regions.
Batch prediction
Why it's wrong here
Batch prediction is for asynchronous, large-scale predictions, not real-time low latency.
Model Monitoring
Why it's wrong here
Model Monitoring detects drift, not serving requests.
Global endpoints
Why this is correct
Global endpoints automatically route to the closest region, providing low latency across regions.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
