Alibaba ACA Cloud Operator study guide
Alibaba ACA Cloud Operator · Work through your exam, one topic at a time.
The ACA Cloud Operator credential is an Alibaba Cloud associate-level certification aimed at practitioners who run day-to-day cloud environments rather than design them. It suits cloud operations engineers, system administrators, NOC/SOC staff, and DevOps or platform team members who are expected to provision, monitor, secure, and keep cloud workloads cost-efficient. Candidates typically already have hands-on exposure to a cloud console and basic Linux or networking skills. The exam is delivered as multiple choice and is organized into four equally weighted domains, each worth 25 percent: Cloud Operations Fundamentals; Compute Operations (ECS); Storage and Networking Operations; and Monitoring, Security and Cost Operations. The Alibaba ACA Cloud Operator study guide has 4 sections and about 1,965 words.
01Cloud Operations Fundamentals
Alibaba Cloud operations rest on a shared responsibility split: the platform secures the physical data centers, hypervisor, and managed service control planes, while the customer secures guest OS configuration, identity and access, data, and network policy inside their VPCs. Questions frequently test where that line falls for a given service type.
388 words, about 2 min02Compute Operations (ECS)
Elastic Compute Service (ECS) instances are defined by instance family (general purpose, compute-optimized, memory-optimized, and specialized types), vCPU/memory ratio, and the image used to boot. Understand the lifecycle states: creating, running, stopped, and released.
388 words, about 2 min03Storage and Networking Operations
Alibaba Cloud offers Object Storage Service (OSS) for unstructured objects in buckets, cloud disks (block storage) for ECS, Network Attached Storage (NAS) for shared file access, and archive/cold tiers within OSS. Key concepts: buckets are region-scoped and globally unique in name; objects have keys and storage classes (standard, infrequent access, archive, cold archive) with different retrieval behavior and minimum storage durations.
391 words, about 2 min04Monitoring
CloudMonitor is the central service for metrics, events, and alerts across Alibaba Cloud resources. It collects built-in metrics for services like ECS, RDS, SLB, and OSS, and supports custom metrics pushed from applications.
