AA software development discipline where software is built so that it can be released to production at any time.

BA software development discipline where software is released continuously as part of an automated pipeline.

CBuilding in 60 minutes or less.

DA software development practice where contributors are integrating their work very frequently.

Answer : D

Continuous integration doesn't mean that software can or will be released or pushed to production continuously.

Question 3

You want to deploy a Jenkins pipeline, but you are concerned about the total amount of time it will take for the deployment to complete, and you aren't concerned with files left in the working directory after a build. What should you do?

ATune the 'timer' section for the project.

BChoose not to use a clean checkout.

CThere's no way to reduce the time

DUse a clean checkout.

Answer : B

You can save time by not choosing to have a clean checkout for each build

Question 4

Your supervisor has asked you to explain to the company's development team how using Jenkins will implement continuous integration. You want to make sure the developers understand what that means to them. Which of the following is the most succinct ?

AThe changes the team makes will be released to production at any time.

BThe software development team will increase the frequency at which code changes are committed to the build, test, and deployment cycles.

CSoftware changes will now be added to an automated pipeline.

DBuild time objectives will be targeted to take less than 60 minutes.

Answer : B

A central tenant of continuous integration is integrating work frequently.

Question 5

What's a benefit of a clean checkout over an incremental update?

AIt ensures the working directory is clean and not tampered with

BNone of these

CIt's faster

DIt ensures there are no mistakes

Answer : A

A user, or previous build, could create or change a file in a workspace which could cause problems with future builds.

Question 6

What's the difference between pushing and pulling code from a CI perspective?

APulling is more efficient.

BWhen the source informs the build system of a code change, that's pushing. When the build system asks if there are changes to the source code, that's pulling

CPushing uses more resources.

DWhen the source informs the build system of a code change, that's pulling. When the build system asks if there are changes to the source code, that's pushing

Answer : B

Pushing is generally preferred as it assures the action is only performed as changes are made.

Question 7

What's a benefit of incremental updates over a clean checkout?

AIt ensures there are no mistakes

BNone of these

CIt's faster

DIt's more thorough

Answer : C

Instead of deleting and re-cloning a project repository into a workspace, you can save time by just pulling any changes. This can be problematic when files produced during the build may persist and cause issues in future builds.
