Exam Question 17
What cultural shift does DevOps describe?
A. Close collaboration between developers and IT operations staff
B. Sharing of responsibilities across departmental lines
C. The dissolution of departmental silos
D. All of the above
Correct Answer:
D. All of the above
Answer Description:
DevOps is an attempt to consolidate IT departments into a more cohesive team — not just developers and IT operations, as the term itself belies, but networking, security and quality assurance as well, just to name a few. There are now offshoots, such as DevSecOps, BizDevOps and DevNetOps, that aim for additional unification. All ultimately aim for the same goal: cohesion and efficiency.
Exam Question 18
What defines the DevOps process loop?
A. Plan, build, release, deploy, monitor
B. Code, test, deploy, operate, monitor, plan
C. Plan, code, build, test, deploy, operate, monitor, plan
D. Build, test, release, monitor
Correct Answer:
C. Plan, code, build, test, deploy, operate, monitor, plan
Answer Description:
It reads like a lot of steps, but the addition of scripts, automation and machine learning reduces a significant volume of manual intervention. The planning stage is the loop’s starting and ending point, informed by the existing code to inform the development of subsequent code updates. DevOps’ emphasis on collaboration also means that some steps act concurrently, such as continuous testing through the coding and building processes, and monitoring is a key aspect of ongoing operation.
Exam Question 19
True or false: A new DevOps team will revolutionize the IT department.
A. True
B. False
Correct Answer:
B. False
Answer Description:
The easiest route is often the most deceiving. While it seems like a good idea to pull the best IT pros out of each department to work together as a cohesive team, what results is simply another new siloed IT team to join the lineup. Instead of creating a department to oversee other departments, instate a DevOps center of excellence to foster a panel of experts who can, instead, lead both the IT divisions and the business as a whole toward the organization’s end goal.
Exam Question 20
What problems does DevOps solve?
A. Long deployment cycles
B. Brittle infrastructure and application code
C. Inefficient or out-of-date applications
D. All of the above
Correct Answer:
D. All of the above
Answer Description:
DevOps is designed to break up deployments into much smaller pieces to enable IT organizations to make faster and simpler updates that don’t take months of effort to complete — and that don’t create extended periods of downtime. DevOps also encourages IT organizations to update their tooling to take advantage of these benefits.
