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 before it is promoted to production
- B. Restructuring and monitoring tests must be run after it is promoted to production
- C. Functional and nonfunctional tests must be run after it is promoted to production
- D. Restructuring and monitoring tests must be run before it is promoted to production
Answer: A
Explanation:
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.

NEW QUESTION # 57
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 CI server was not configured as a Git remote for the repository.
- B. The pipeline must be started manually after the code repository is updated.
- C. The webhook call from the code repository did not reach the CI server.
- D. Configuration changes must be sent to the pipeline, which then updates the repository.
Answer: C
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 # 59
As a department starts following NetDevOps principles, how should the network monitoring strategy be updated to provide more visibility into the user experience?
- A. Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols
- B. Identify and capture the key performance indicators that describe the state of the network
- C. Identify and fix network issues faster by leveraging streaming telemetry from network devices
- D. Leverage machine learning tools to more quickly identify problems m syslog and SNMP data
Answer: A
Explanation:
Explanation
Updating tools to pull or stream monitoring metrics from APIs instead of using legacy protocols is an important part of a NetDevOps strategy, as it allows for more efficient and automated data collection, as well as better visibility into the user experience. APIs for network monitoring are becoming increasingly common, as they allow for a more direct connection to the devices themselves, and can provide access to more detailed and specific metrics. Cisco's DevOps Solutions and Practices Guide recommends leveraging APIs to monitor the user experience, as they can provide access to more specific metrics and can be integrated with other monitoring tools.
NEW QUESTION # 60
Which method is a safe way to provide a username/password combination to an application running as a service in a Docker container?
- A. Docker environment variable
- B. encode the value with base64 in a secure DNS CTEXT entry

- D. Docker secrets
Answer: D
Explanation:
Explanation
a docker secret is a blob of data, such as a password, SSH private key, SSL certificate, or another piece of data that should not be transmitted over a network or stored unencrypted in a Dockerfile or in your application's source code

NEW QUESTION # 63
When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)
- A. cone testing
- B. mean time to recover
- C. mean time between success
- D. change lead time
- E. age of codebase
Answer: B,D
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.
