Start Analyze and optimize technical and business processes PracticeA 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.
A startup uses Cloud Functions with a Pub/Sub trigger to process incoming orders. They notice that the function sometimes fails to process messages, and those messages are lost. What is the most likely cause?
Explanation: Option D is correct because when a Cloud Function fails to process a Pub/Sub message and retry on failure is set to false, the message is not redelivered. Pub/Sub relies on the subscriber (the Cloud Function) to acknowledge messages; without retries, a failed execution causes the message to be dropped after the ack deadline expires, leading to message loss.
A company uses BigQuery for analytics. They have a large partitioned table that is queried frequently. The query performance has degraded over time. Which optimization should they try first?
Explanation: Clustering on frequently filtered columns reorganizes the data within partitions based on the values of those columns, which allows BigQuery to prune blocks more effectively during queries. This directly addresses the performance degradation by reducing the amount of data scanned, without requiring additional storage or compute resources.
An organization runs a Kubernetes cluster on GKE with cluster autoscaling enabled. They notice that pods are frequently in 'Pending' state due to insufficient CPU, but the cluster autoscaler does not add nodes quickly enough. What is the most likely cause?
Explanation: Option D is correct because the cluster autoscaler cannot add new nodes if the node pool has already reached its maximum node count limit. This limit is configured at the node pool level in GKE, and once reached, the autoscaler will not scale up further, leaving pods in 'Pending' state due to insufficient CPU resources.
