An organization has issues with code-based failures after implementing a CI/CD pipeline to automate the builds and deployment phases of an application.
Which action must be added to the pipeline, after the application is deployed in the staging environment to minimize failures and to ensure a successful continuous deployment?
Restructuring and monitoring tests must be run after it is promoted to production
Restructuring and monitoring tests must be run before it is promoted to production
Functional and nonfunctional tests must be run after it is promoted to production
Functional and nonfunctional tests must be run before it is promoted to production
Explanation:
According to Cisco's Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, it is important to run functional and non-functional tests before promoting the application to production. This is essential in order to identify and address any issues that could cause code-based failures. Additionally, a pipeline should include automated tests that can be used to verify that processes are running correctly. By running these tests before promoting to production, you can ensure that any potential issues are identified and addressed before the application is released.
When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)
mean time between success
mean time to recover
cone testing
change lead time
age of codebase
Explanation:
Change lead time is the amount of time it takes for a proposed change to go from the idea phase to being fully deployed in production. This metric can be used to measure the speed and efficiency with which changes are implemented, which is often indicative of an organization's DevOps maturity.
Mean time to recover (MTTR) is the average amount of time it takes to restore a service or application to its working state when an issue arises. MTTR is an important metric for measuring the resilience of an organization's infrastructure, and is another indicator of DevOps maturity.

A DevOps engineer must build a Docker image to containerize an application. Then the image must be pushed to a repository on Docker Hub in a CI/CD pipeline using GitHub Actions.
Which approach securely encrypts the Docker Hub access token as an environment variable within the CI/CD pipeline?
Store the access token with GitHub environment variables
Store the access token with GitHub encrypted secrets
Store the access token in an environment file in the repository
Hard code the access token in the repository with Base64 encoding
An application has been designed based on microservices. The application is deployed on Kubernetes using multiple pods that share the same IP address. Each pod is responsible for a service in the application.
Which command validates the success of the application deployment?
kubectl get pods -o wide -w
kubectl rollout status deployment
kubectl describe pods/
kubectl rollout history deployment
A team must roll out updates on the production instance of an application. To avoid any service down time, the new version must be released alongside the old version. After the team ensures that the new version operates as it should, traffic will be redirected to the new version. Then the old version will be shut down.
Which deployment strategy must be used?
Unlock Premium Member
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.)
Changes must be scheduled to deploy at a specific time that has minimal traffic
Changes must include automated tests
Changes must be validated during deployment to the production environment
Smaller, individually testable changes must be merged first
Team members must be responsible for the code committed by any team member
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?
Implement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored
Generate the ConfigMaps specific to the environment by using a templating language such as Jinja2 and store the ConfigMaps in unique branches of a repository
In the master branch where the ConfigMaps are stored, create a branch for each environment that contains an environment-specific ConfigMap.
Create a unique repository for each environment that contains ConfigMaps for that environment to ensure that each environment can be deployed independently
An application is being developed to be used by the HR department of a company on a global scale.
The application will be used as a central repository for employee contracts. For user access, a RADIUS server will be used with authorized user groups.
Which action must be used to prevent developers from accidentally committing secrets in the code?
Add a unit test to block the secrets
Add a precommit Git hook to block the secrets
Add dast to the repository to block the secrets
Add a job in the CI build to block the secrets

The IT team is creating a new design for a logging system. The system must be able to collect logs from different components of the infrastructure using the SNMP protocol. When the data is collected it will need to be presented in a graphical UI to the NOC team.
What is the architectural component that needs to be placed in the unlabeled box to complete this design?
message queue
web server
log parser
time-series database
Explanation:
A log parser is a software component that is used to collect and parse log data from various sources, such as infrastructure devices, applications, and services. It is responsible for collecting log data from the various sources and then mapping it to a specific format that can be easily consumed and interpreted by the NOC team. The log parser can also be used to filter out irrelevant data and store the processed data in a time-series database. This data can then be used by the NOC team to generate visualizations and reports, which will help them identify and address any issues within the infrastructure.

Which two statements about Infrastructure as Code are true? (Choose two.)
Test-driven development practices make use of Infrastructure as Code.
Infrastructure as Code refers to automated testing libraries.
DevOps builds upon Infrastructure as Code.
Infrastructure as Code is based on practices from software development.
Infrastructure as Code must use the same programming language as the application.
Explanation:
(IaC) is a practice that allows for the automation of infrastructure configuration and deployment, allowing DevOps teams to deploy and manage infrastructure with the same release pipelines and versioning as source code [1]. IaC is based on practices from software development, and promotes the use of automation and repeatable processes to ensure consistency of deployments.
