AWS DevOps Engineer Professional Final Exam Study
Guide 2022 with complete solution
Continuous Integration .>>Development practice that requires devs to push code to a
repo often. A tester/builder checks the code as soon as it is published which allows
devs to receive feedback faster. This allows devs to focus on writing code rather than
running and waiting for tests to build & compile.
Continuous Delivery .>>Development practice that ensures software can be released
reliably whenever needed. This ensures frequent as well as quick deployments. Most of
the deployment is automated but may involve a manual approval step. (semi
automation)
Continuous Deployment .>>A set of practices that enable every change that passes
automated tests to be automatically deployed to production with no need for manual
intervention (full automation).
branch, pull .>>GIT best practices dictate that if you have NEW changes to make to a
code base, you should utilize a _______ rather than a new repository. You can then
create _____ requests then merge into master.
IAM Policy With Explicit Deny .>>In AWS, how do you protect pushes/merges from
unauthorized users to the master branch (using Code Commit).
T .>>T/F: Code Commit contains several triggers and configurable notifications that can
call SNS topics and Lambda functions in response to various activity within your
repository.
AWS Code Build .>>A fully managed build service that is continuously scaling. It
leverages docker under the hood and is secured through compatibility with AWS KMS,
VPC's, and AWS Cloudtrail.
5 minutes, 8 hours .>>The minimum timeout for AWS Code Build?
The maximum timeout for AWS Code Build?
buildspec.yml .>>A collection of build commands and related settings, in YAML format,
that CodeBuild uses to run a build.
env .>>This optional parameter of the buildspec.yml file allows for variable declaration,
parameter-store, exported variables, secrets-manager, et.al.
phases .>>This parameter of the buildspec.yml file allows you to designate commands
that will occur during the install, pre_build, build, and post_build stages of the build/test.
artifacts .>>This parameter of the buildspec.yml file allows you to save various files after
a build is done (S3).
cache .>>This parameter of the buildspec.yml file is used to store files which can speed
up deployment during subsequent builds/tests.
finally .>>This parameter of the buildspec.yml file will allow you to designate commands
to run even if prior commands fail.
override .>>You can specify env variables in buildspec.yml OR you can add them as
environment variables ___________ when configuring a new build operation (from the
console).
Parameter Store, Secrets manager .>>What two services can you utilize/integrate with
your code build deployment to encrypt your environment variables during a build?
T .>>T/F: Code Build allows you to encrypt artifacts before your upload them to S3
(natively within Code Build)
Cloudwatch Logs .>>How can you view your previous Code Build history if the docker
container that was spun up to build your application has been terminated post-build?
T .>>T/F: You can utilize pre-built dashboards, create your own, and view metrics
related to your Code Build deployments.
CloudWatch Events .>>Using this service, you can trigger code build at certain fixed
intervals OR trigger a build in response to certain actions (i.e. code commit push)
Code Deploy .>>A fully managed deployment service that automates software
deployments to a variety of compute services such as Amazon EC2, AWS Fargate,
AWS Lambda, and your on-premises servers.
Code Deploy Agent .>>In order for EC2/On-premise server to work with Code Deploy,
what must each instance have?
F: only works for EC2 .>>T/F: Blue/Green deployment works for both EC2 and on-prem
T .>>T/F: Code Deploy does NOT provision resources (i.e. EC2 instances/lambda
functions)
Tags .>>You can utilize ____ with deployment groups to separate your different
environment types (for example) within a Code Deploy deployment.
In-Place .>>This type of Code Deploy deployment updates existing applications directly
(may result in down time).
