Q: An AWS Lambda cold start occurs on every single invocation of a function.
- True
- False
A: False

Q: What is the maximum execution duration for a single AWS Lambda invocation?
- 5 minutes B) 15 minutes C) 60 minutes D) No limit
A: 5 minutes B) 15 minutes C) 60 minutes D) No limit

Q: A team sets up a scheduled ping every 5 minutes to keep their Lambda function "warm." What is the main limitation of this approach?
- It increases cold start duration B) It only keeps one instance warm, so concurrent bursts still hit cold starts C) It violates AWS's terms of service D) It disables auto-scaling entirely
A: It increases cold start duration B) It only keeps one instance warm, so concurrent bursts still hit cold starts C) It violates AWS's terms of service D) It disables auto-scaling entirely

Q: With standard EKS or GKE (non-Autopilot), the cloud provider manages the control plane, but the customer is still responsible for node management, upgrades, IAM/RBAC, and network policy.
- True
- False
A: True

Q: Which managed Kubernetes offering goes furthest in fully abstracting away the data plane (node management) by default?
- EKS standard B) AKS standard C) GKE Autopilot D) Self-managed Kubernetes
A: EKS standard B) AKS standard C) GKE Autopilot D) Self-managed Kubernetes

Q: What Kubernetes custom resource must you explicitly configure (with min/max replicas and a target metric) before pods will scale automatically based on load?
Feedback: Sample/expected answer: HorizontalPodAutoscaler (HPA)

Q: Which managed ML platform generally requires you to explicitly configure EC2 instance types and networking (VPCs, security groups) for training jobs, reflecting a philosophy of granular control?
- Vertex AI b) Azure ML AutoML c) Amazon SageMaker AI d) All three require identical configuration
A: Vertex AI b) Azure ML AutoML c) Amazon SageMaker AI d) All three require identical configuration

Q: Stopping a SageMaker notebook instance also automatically stops billing for its attached EBS storage volume.
- True
- False
A: False
