Short Answer

  1. Describe the principle of "Cost of Change is Dead"



  1. Explain the difference between docker and ansible.



  1. Describe the principle of "Rule of 3".



Scenarios

  1. A company wants to increase the responsibility of their development team to include handling testing, staging, and production. They want to reduce communication barriers and team silos separate groups imposes. What team model might be appropriate?


  1. A company has recently adopted continuous deployment of their product, but has started receiving complaints from their customer that new features are coming too fast and running too slow. What practice would you recommend they adopt to prevent these problems while allowing continuous deployment?


### Implementation
  1. Measure the branch coverage of a code snippet. (10 points)

Test suite:

  • weird(0, 0, 0, "strictly", [0,0])
  • weird(88, 42, 42, "stricter", [0,0])
function weird(x,y,z, mode, results)
{
      if( x > 100 || y > 70 )
      {
          z = 33;
          results[0] = getData().data.server().first.name;
      }    
      else if( z == 0 && y < 0)
      {
          if( mode == "strictly" )
          {
              return 0;
          }
      }
      else if( z < 42 )
      {
          if( mode != "stricter" )
          {
              results[1] = getData().cachedResults.first.name;
              return y = z / x;
          }
      }
      return 1;
  }









  1. Write a parser using a simple visitor pattern.

You can assume a basic visitor function already exists and provide your own tokens and AST structure you assume exist (feasibly parsed).

A) Count the number of branches in a function. (10 points)

  • What is number of branches in the above weird function?
  • Parser implementation.








B) Count the number of conditions in a function. (10 points)

  • What is number of conditions in the above weird function?
  • Parser implementation.








Analyze

  1. Two developers are debating about what type of configuration management to use in their organization: traditional or modern. Provide one advantage of traditional CM and one limitation. Provide one advantage of modern CM and one limitation. br/>











  1. Compare and contrast using mocking versus canary releasing. Describe their impact on testing.












Design and Architecture

  1. How might you create a microservice architecture for your bot, running in the cloud? Focus on creating a well annotated diagram that illustrates essential components, paragraphs of just text will not be given credit.
