[All Professional Cloud DevOps Engineer Questions]

You support a stateless web-based API that is deployed on a single Compute Engine instance in the europe-west2-a zone. The Service Level Indicator (SLI) for service availability is below the specified Service Level Objective (SLO). A postmortem has revealed that requests to the API regularly time out. The time outs are due to the API having a high number of requests and running out memory. You want to improve service availability. What should you do?

  • A. Change the specified SLO to match the measured SLI
  • B. Move the service to higher-specification compute instances with more memory
  • C. Set up additional service instances in other zones and load balance the traffic between all instances
  • D. Set up additional service instances in other zones and use them as a failover in case the primary instance is unavailable

Selected Answer: C
C. Set up additional service instances in other zones and load balance the traffic between all instances This option will provide redundancy and increase the availability of the service by distributing the traffic across multiple instances. Additionally, if one instance goes down, the load balancer will redirect the traffic to the other healthy instances, minimizing the impact on the service availability.
