Question: What is the business value that Cloud Pub/Sub can provide?
- Availability, throughput, and latency
- Sources, sinks, and transforms
- VMs, network, and Non-SQL
- Queries, machine learning, and compute
Explanation
Pub/Sub is a managed messaging service that decouples systems using topics and subscriptions. Producers send messages without depending on the availability or processing speed of consumers. Google Cloud manages the messaging infrastructure, which supports reliable event ingestion and delivery at scale. This helps applications handle real-time events without building custom messaging infrastructure.
Why the other options are incorrect
Sources, sinks, and transforms describes Cloud Dataflow, not Pub/Sub.
VMs, network, and Non-SQL mixes unrelated infrastructure and database concepts, not managed messaging.
Queries, machine learning, and compute describes analytics and AI capabilities, not event messaging.
