What is a key benefit of using autoscaling for a web application?

It guarantees zero downtime during deployments

It reduces the need for a load balancer

It adjusts the number of instances based on demand, helping to avoid over-provisioning

It automatically fixes application bugs

What is the purpose of data replication across zones in a Google Cloud database?

To comply with data residency requirements

To reduce storage costs by deduplicating data

To improve query performance by distributing read traffic

To provide failover capability if a zone becomes unavailable

In which scenario is session affinity most beneficial?

When the application is stateless and each request is independent

When the application stores session data in a shared database

When the application maintains an in-memory session state that is not shared across instances

When the application needs to scale horizontally to handle high traffic

A developer needs to deploy a containerized web application that must scale to zero during periods of no traffic and requires no management of the underlying infrastructure. Which Google Cloud compute option best meets these requirements?

App Engine Flexible Environment

What is the primary benefit of using asynchronous integration patterns like Pub/Sub?

It eliminates the need for a database

It guarantees that messages are processed in the exact order they were sent

It allows the producer to continue processing without waiting for the consumer to finish

It reduces the need for authentication between services
