CIS 4355 exam 1 review

What does the %C/A(percent complete and accurate) metric measure in technology value system?

• The speed of code deployment

• The quality of output at each step

• Customer Satisfaction

• Lead time efficiency

How is the DevOps ideal of achieving deployment lead times of minutes primarily accomplished?

• By tightly coupling applications

• By relying on manual testing

• By continuously checking small code changes into version control and automating testing and deployment

• By performing exploratory testing

What characterizes the second phase of work in the technology value stream?

• Sequential processing of large batches of work

• Near-Zero defects and low creativity,

• Long and unpredictable lead times

• High variability of process time and high uncertainty

What is the value stream in the context of Lean Manufacturing?

• A.The sequence of activities to deliver upon a customer request

• B. The sequence of activities to design a product

• C. The sequence of activities to clean the factory floor

• D. the sequence of activities to hire new employees

What does the focus on deployment lead time entail in dev Ops?

• A. Ensure a smooth and even flow of work,

• B. Reducing the role of IT operations

• C. Minimizing the use of version control

• D. Maximizing security and compliance failures

At what point does the technology value stream typically begin in DevOps?

• A. when the business hypothesis is formulated

• B. When the application is running in production

• C. When QA and testing are initiated

• D.When the code is checked into version control

Which of the following is not a technique used to create a smooth flow of work in manufacturing value streams?

• A. Reducing work in Process

• B.Small batch sizes

• C. Continuous system optimization

• D. Increasing rework

  
  

In a typical DevOps transformation, what is often the initial constraint that need to be addressed?

• A. Test setup and run

• B. Code Deployment

• C. Tight architecture

• D. Environment creation

What was the common manufacturing practice prior to the lean revolution regarding batch sizes?

• A. Manufacturing in small batch sizes

• B.Manufacturing in single piece flow

• C. Manufacturing in large batch sizes

• D. Manufacturing with minimal setup time

According to Dominica DeGrandis, why is controlling queue size (WIP) important in managing work in technology value stream?

• A. It makes work invisible

• B.It is a leading indicator of lead time

• C. It encourages multitasking among team members

• D. It eliminates the need for Kanban boards
