Question 5

An organization is developing an application using Git. Each team member is assigned to work on specific parts of the application. At the end of each task, individual code parts are merged in the main build.

Which two requirements should be implemented to increase the likelihood of continuous integration? (Choose two.)

AChanges must be scheduled to deploy at a specific time that has minimal traffic

BChanges must include automated tests

CChanges must be validated during deployment to the production environment

DSmaller, individually testable changes must be merged first

ETeam members must be responsible for the code committed by any team member

Answer : B, C

Question 6

A development team uses Kubernetes for application development. Any changes on ConfigMap are performed manually for each development, test, and production environment. The edits are performed to deploy applications. This approach causes inconsistent deployments across all environments.

Which practice improves the consistency of the deployments?

AImplement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored

BGenerate the ConfigMaps specific to the environment by using a templating language such as Jinja2 and store the ConfigMaps in unique branches of a repository

CIn the master branch where the ConfigMaps are stored, create a branch for each environment that contains an environment-specific ConfigMap.

DCreate a unique repository for each environment that contains ConfigMaps for that environment to ensure that each environment can be deployed independently

Answer : A

Question 7
