Which step should be omitted from the pipeline?
  1. Deploy the code to one or more environments, such as staging and/or production.
  2. Build one of more containers that package up code and all its dependencies.

  5. Log files are aggregated into a single file on individual nodes.

Question 3
An organization manages a large cloud-deployed application that employs a microservices architecture. No notable issues occur with downtime because the services of this application are redundantly deployed over three or more data center regions. However, several times a week reports are received about application slowness. The container orchestration logs show faults in a variety of containers that cause them to fail and then spin up brand new. 
Which action must be taken to improve the resiliency design of the application while maintaining current scale?
  1. Update the base image of the containers.
  2. Test the execution of the application with another cloud services platform.
  3. Increase the number of containers running per service.
  4. Add consistent “try/catch(exception)” clauses to the code.
Correct answer: D
