ACA ACA Container and Serverless Services 1 — Questions and Answers
Question 1: What is Alibaba Cloud Container Service for Kubernetes (ACK)?
- A managed relational database optimized for containers
- A fully managed Kubernetes service that simplifies deploying and managing containerized applications (Correct answer)
- A serverless function execution environment
- A container image registry service
Correct answer: A fully managed Kubernetes service that simplifies deploying and managing containerized applications
ACK is Alibaba Cloud's managed Kubernetes offering that handles the control plane, node provisioning, and upgrades so users can focus on running workloads.
Question 2: Which Alibaba Cloud service is used as a private registry to store and manage Docker container images?
- Container Service for Kubernetes (ACK)
- Container Registry (ACR) (Correct answer)
- Elastic Container Instance (ECI)
- Function Compute (FC)
Correct answer: Container Registry (ACR)
Alibaba Cloud Container Registry (ACR) provides secure private repositories for storing, versioning, and distributing Docker and OCI-compatible container images.
Question 3: What is Alibaba Cloud Elastic Container Instance (ECI)?
- A managed Kubernetes cluster service
- A serverless container runtime that runs pods without managing underlying nodes (Correct answer)
- A CI/CD pipeline tool for container deployments
- A container image scanning and vulnerability tool
Correct answer: A serverless container runtime that runs pods without managing underlying nodes
ECI lets you run Kubernetes pods in a serverless fashion — you specify the container image and resources, and Alibaba Cloud handles all node-level infrastructure.
Question 4: Which ACK cluster type provides the highest level of managed infrastructure by running worker nodes as serverless ECI pods?
- Dedicated Kubernetes Cluster
- Managed Kubernetes Cluster
- Serverless Kubernetes Cluster (ASK) (Correct answer)
- Edge Kubernetes Cluster
Correct answer: Serverless Kubernetes Cluster (ASK)
Alibaba Cloud Serverless Kubernetes (ASK) runs workloads directly on ECI, eliminating both master and worker node management for a fully serverless Kubernetes experience.
Question 5: What is Alibaba Cloud Function Compute (FC)?
- A managed Kubernetes cluster for microservices
- An event-driven serverless compute service where you run code without provisioning servers (Correct answer)
- A batch processing service for large-scale data jobs
- A managed virtual machine service with auto-scaling
Correct answer: An event-driven serverless compute service where you run code without provisioning servers
Function Compute is Alibaba Cloud's FaaS (Function-as-a-Service) offering that executes your code in response to events and automatically scales with no server management.
Question 6: Which of the following can be used to trigger a Function Compute function automatically?
- Only HTTP requests from the internet
- Events from OSS, API Gateway, Log Service, Timer, CDN, and more (Correct answer)
- Only manual invocations via the Alibaba Cloud console
- Only messages from a dedicated Function Compute message bus
Correct answer: Events from OSS, API Gateway, Log Service, Timer, CDN, and more
Function Compute supports multiple trigger types including HTTP, OSS events, RocketMQ messages, Timer (cron), Log Service, API Gateway, and CDN, enabling event-driven architectures.
