20+ practice questions focused on Analyze and optimize technical and business processes — one of the most tested topics on the Google Professional Cloud Architect exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Analyze and optimize technical and business processes PracticeA company wants to reduce costs for a Cloud Storage bucket that stores infrequently accessed archival data. The data is accessed roughly once a quarter. Which storage class should they use?
Explanation: The Coldline storage class is designed for data accessed less than once a quarter, making it the most cost-effective choice for data accessed roughly once a quarter. It offers lower storage costs than Standard or Nearline, with retrieval fees and a 90-day minimum storage duration that suits quarterly access patterns.
A developer ran the command `gcloud compute instances describe instance-1 --zone us-central1-a` and received the above output. They want to create another instance with the same configuration, except with a different external IP. Which action should they take?
Explanation: The `gcloud compute instances describe` output shows the instance has an external IP that is ephemeral (not reserved). To create a new instance with the same configuration but a different external IP, the simplest approach is to create a new instance without specifying a static IP, which will automatically assign a new ephemeral IP. This avoids the overhead of reserving and managing a static IP when only a temporary, different address is needed.
Drag and drop the steps to set up a Cloud SQL for PostgreSQL instance with high availability into the correct order.
Explanation: HA configuration creates a primary and standby in different zones. Private IP requires VPC peering.
A company is migrating its on-premises Oracle database to Cloud SQL for PostgreSQL. The database team wants to minimize downtime during migration. Which approach should they use?
Explanation: Database Migration Service (DMS) for PostgreSQL with continuous migration is the correct approach because it supports ongoing change data capture (CDC) from Oracle to Cloud SQL for PostgreSQL, enabling near-zero downtime. DMS handles schema conversion and data replication continuously, allowing the target to stay synchronized until a cutover, which minimizes downtime compared to batch methods.
An e-commerce platform uses Cloud Spanner for order processing. Recently, latency spikes have occurred during flash sales. The team suspects hot spots due to monotonically increasing order IDs. Which table design change would best solve this?
Explanation: Monotonically increasing primary keys (like sequential order IDs) cause hot spots in Cloud Spanner because all writes are directed to a single split (tablet), overwhelming that node. Adding a random prefix (e.g., a hash of the customer ID) distributes writes across multiple splits, eliminating the hot spot and reducing latency spikes during high-throughput flash sales.
