   A company is evaluating serverless computing for a new application. The application has a component that processes streaming data in near real-time and another component that performs a long-running batch analysis that can take up to an hour. What is a valid consideration when using serverless functions?

   • AServerless functions are not suitable for streaming data because they cannot be triggered by events
   • BServerless functions require managing underlying servers, which increases operational overhead
   • CServerless functions are suitable for the streaming component but may have execution time limits that affect the batch analysis
   • DServerless functions are ideal for both components because they have no execution time limits

   A team is developing a cloud-native application and wants to follow the twelve-factor methodology. They are facing a challenge: the application needs to handle different configurations for development, staging, and production, and they want to avoid storing configuration in the code repository. They also want to ensure that configuration changes can be made without redeploying the application. Which approach aligns with twelve-factor principles?

   • AStore configuration in environment variables
   • BUse a configuration management tool to inject configuration at build time
   • CStore configuration in a configuration file in the code repository
   • DHardcode configuration values in the application code

   A retail company is migrating its monolithic order-processing application to a cloud-native architecture. The team wants to deploy each business capability (inventory, payments, shipping) as an independently deployable unit, and they need to scale the inventory service separately during peak sales events. Which approach best meets these requirements?

   • AKeep the monolith but use a load balancer to distribute traffic to multiple VM instances
   • BRefactor the application into multiple microservices, each packaged as a container, and orchestrate them with Kubernetes
   • CUse serverless functions for the entire application, with each function representing a business capability
   • DDeploy the entire application as a single container and scale the container instance count
