Google Associate Cloud Engineer (ACE) Exam Study Guide 2026

ACE vs. Professional Cloud Architect: Which One First?

The Google Associate Cloud Engineer (ACE) and the Professional Cloud Architect (PCA) are both widely respected GCP credentials, but they target very different skill levels. The ACE validates your ability to deploy, monitor, and maintain GCP workloads using the console and the gcloud CLI. The PCA validates your ability to design enterprise-grade cloud architecture from scratch.

If you are new to GCP, start with the ACE. It gives you the hands-on foundation — Compute Engine, GKE, Cloud Storage, IAM, VPC networking — that makes the Professional exams approachable. Many professionals also hold only the ACE, as it is sufficient for most cloud engineering and DevOps roles that involve day-to-day GCP operations.

The 5 Exam Domains

Google structures the ACE around five task categories:

• Setting up a cloud solution environment (17.5%): Creating projects, billing accounts, enabling APIs, configuring Cloud Identity, and setting up the gcloud CLI.
• Planning and configuring a cloud solution (17.5%): Choosing compute options (GCE, GKE, Cloud Run, App Engine), selecting storage classes, and estimating costs with the pricing calculator.
• Deploying and implementing a cloud solution (25%): Deploying VMs, managed instance groups, GKE clusters, Cloud Functions, and data solutions like Cloud SQL and Bigtable.
• Ensuring successful operation of a cloud solution (20%): Managing and monitoring resources with Cloud Monitoring, Cloud Logging, and Error Reporting; managing IAM roles; scaling and updating deployments.
• Configuring access and security (20%): IAM best practices, service accounts, VPC firewall rules, SSL certificates, and Cloud Armor.

Compute, Storage, and Networking Fundamentals

Compute

Know when to use each compute option: Compute Engine for full VM control, GKE for containerized workloads needing orchestration, Cloud Run for stateless containers without cluster management, App Engine Standard for fully managed HTTP apps with fast scaling to zero, and Cloud Functions for event-driven single-purpose code.

Storage

Understand the four Cloud Storage classes (Standard, Nearline, Coldline, Archive) and their retrieval cost trade-offs. Know when to use Cloud SQL vs. Cloud Spanner vs. Firestore vs. Bigtable — this is one of the most-tested decision trees on the ACE exam.

Networking

VPC fundamentals are essential: subnets, firewall rules, Cloud NAT, VPC peering, and Shared VPC. Know the difference between Internal and External IP addresses, and understand when to use Cloud Load Balancing types (HTTP(S), TCP, UDP).

Essential gcloud Commands

The ACE exam includes questions about CLI commands. You do not need to memorize every flag, but you should recognize correct command structure for common tasks:

• gcloud compute instances create — create a VM with specified machine type, zone, and image.
• gcloud container clusters create — create a GKE cluster.
• gcloud iam service-accounts create — create a service account.
• gsutil cp / mb / rb — copy files, create buckets, and delete buckets in Cloud Storage.
• gcloud config set project — switch active project context.
