The answer is to increase maxReplicaCount to 10. This is correct because scaling endpoints to reduce latency relies on allowing the autoscaler to provision more replicas during traffic spikes, which directly distributes the incoming request load and reduces queueing at each individual instance. By raising the maximum replica count, you ensure the system has sufficient capacity to handle peak demand, preventing requests from piling up and causing high per-instance latency. On the Google Cloud Generative AI Leader exam, this tests your understanding of autoscaling configuration as a direct remedy for queueing-induced latency, often appearing as a trap where candidates mistakenly adjust thresholds or model versions instead of addressing capacity limits. A key memory tip is to think of maxReplicaCount as the “ceiling” for your fleet—raising it gives the autoscaler room to breathe during spikes, while lowering it creates a bottleneck.

This Generative AI Leader practice question tests your understanding of techniques to improve generative ai model output. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Refer to the exhibit. The endpoint is experiencing high latency during traffic spikes. The team wants to improve response time by reducing queueing. Which change to the configuration would be most effective?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase maxReplicaCount to 10
Increasing maxReplicaCount to 10 allows the autoscaler to provision more replicas during traffic spikes, distributing the incoming requests across additional endpoints. This directly reduces queueing at each replica because the load is spread over more instances, lowering per-instance latency. The change targets the root cause—insufficient capacity to handle peak load—rather than adjusting thresholds or model versions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Decrease minReplicaCount to 0
Why it's wrong here
Fewer minimum replicas can increase cold starts.
✗
Change the model version to '2'
Why it's wrong here
Model version doesn't affect latency directly.
✗
Decrease the target value in autoscaling metric to 50
Why it's wrong here
Lower target triggers scaling earlier but may not reduce queueing if max replicas are insufficient.
✓
Increase maxReplicaCount to 10
Why this is correct
More replicas handle higher load.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that lowering the autoscaling target metric (Option C) is the primary fix for high latency, when in fact the maxReplicaCount ceiling is the bottleneck that must be raised to allow sufficient capacity during spikes.
Detailed technical explanation
How to think about this question
Under the hood, autoscaling policies in platforms like SageMaker or Kubernetes-based inference endpoints use metrics such as 'requests per replica' or 'CPU utilization' to trigger scale-out events. The maxReplicaCount acts as a hard ceiling; if the ceiling is too low, even with aggressive scaling thresholds, the system cannot provision enough replicas to absorb the load, causing requests to queue in the load balancer or inference container. In real-world scenarios, a common mistake is to lower the target metric without raising maxReplicaCount, leading to rapid scaling but still hitting the cap and experiencing latency spikes.

Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
