NEW QUESTION # 64
When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)
- A. mean time between success
- B. mean time to recover
- C. change lead time
- D. age of codebase
- E. cone testing
Answer: B,C
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.

NEW QUESTION # 67
Refer to the exhibit.
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?
- A. Functional and nonfunctional tests must be run after it is promoted to production
- B. Restructuring and monitoring tests must be run before it is promoted to production
- C. Restructuring and monitoring tests must be run after it is promoted to production
- D. Functional and nonfunctional tests must be run before it is promoted to production
Answer: D
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.

- B. Create a unique repository for each environment that contains ConfigMaps for that environment to ensure that each environment can be deployed independently
- C. 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
- D. Implement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored

NEW QUESTION # 72
Which interface is most commonly used to integrate logging, monitoring, and alerting applications into your CI/ CD pipeline?
- A. SSH
- B. SNMP
- C. REST
- D. AMQP
Answer: C
Explanation:
The most commonly used interface to integrate logging, monitoring, and alerting applications into your CI/CD pipeline is REST. Representational State Transfer (REST) is an architectural style that defines a set of constraints and properties based on HTTP. It enables developers to create APIs that are easy to use and access, and is well-suited for integrating logging, monitoring, and alerting applications into your CI/CD pipeline.
NEW QUESTION # 73
A developer has created a deployment that should launch a pod to run their database service. The pod should launch with a metadata name of "Cisco-DB," and the developer has added it to the "Cisco" namespace in their deployment.
Which Kubernetes command confirms that the service is running and usable?
- A. kubectl get pods | grep "Cisco-DB"
- B. kubectl -n Cisco get services | grep "Cisco-DB"
- C. kubectl -n Cisco get service | grep "Cisco-DB"
- D. kubectl -n Cisco get pods | grep "Cisco-DB"

NEW QUESTION # 74
A company has a CI/CD pipeline implemented to automate application deployment. An urgent change is required in the production environment. A developer produces and tests the required change in the company's environment, but the pipeline fails when pushed.
Which action conforms to the rules of a CI/CD pipeline and enables the pipeline to pass?
- A. Remove the failing test.
- B. Replicate the production environment in the pipeline before applying
- C. Manually deploy the change into the production environment
- D. Use a backup pipeline
Answer: B
Explanation:
Explanation
This ensures that the change is applied in the same environment that it was tested in, and that the pipeline will pass. This is in accordance with the rule of a CI/CD pipeline that states that the same environment should be used for testing and deploying code into production. As stated in the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, "the same environment should be used for testing and deploying code into production, or the pipeline will fail."

NEW QUESTION # 82
Configuration changes to the production network devices are performed by a CI/CD pipeline. The code repository and the CI tool are running on separate servers. Some configuration changes are pushed to the code repository, but the pipeline did not start.
Why did the pipeline fail to start?
- A. The webhook call from the code repository did not reach the CI server.
- B. The pipeline must be started manually after the code repository is updated.
- C. Configuration changes must be sent to the pipeline, which then updates the repository.
- D. The CI server was not configured as a Git remote for the repository.
Answer: A
Explanation:
A webhook is basically a callback URL that is triggered when certain events occur, such as a code commit. If the webhook call from the code repository does not reach the CI server, then the pipeline will not start. According to the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, "A webhook is a web-based feature that enables a remote service to communicate with a local service, usually through a web server. Webhooks are used to trigger an action when a specific event occurs, usually in a remote service or application."
NEW QUESTION # 83
What are two advantages of using Configuration Management Tools? (Choose two.)
- A. reduction in policy violations caused by human errors
- B. reduction in network changes already performed automatically
- C. reduction in networking team skills
- D. reduction in administration costs
- E. reduction of on-premises networking equipment
Answer: A,D
Explanation:
Explanation
Configuration Management Tools allow for automated configuration of networking equipment, which helps to reduce human errors and the time and money needed to manage and configure the equipment. For example, Cisco Configuration Professional (CCP) is a configuration management tool that provides automated configuration, validation, and troubleshooting of network infrastructure devices. CCP enables administrators to configure and deploy network changes quickly and efficiently, while also reducing the costs associated with manual configuration and troubleshooting.

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?
- A. message queue
- B. log parser
- C. web server
- D. time-series database
Answer: D
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.
