NEW QUESTION # 80
As a department starts following NetDevOps principles, how should the network monitoring strategy be updated to provide more visibility into the user experience?
- A. Identify and fix network issues faster by leveraging streaming telemetry from network devices
- B. Leverage machine learning tools to more quickly identify problems m syslog and SNMP data
- C. Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols
- D. Identify and capture the key performance indicators that describe the state of the network
Answer: C
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 # 81
Microservices architecture pattern has been applied and the system has been architected as a set of services.
Each service is deployed as a set of instances for throughput and availability. In which two ways are these services packaged and deployed? (Choose two.)
- A. Service must be independently deployable and scalable.
- B. Service instances do not need to be isolated from one another.
- C. Service must be dependent, deployable, and scalable.
- D. Service are written using the same languages, frameworks, and framework versions.

Answer: A,E
NEW QUESTION # 82
Fill in the blank to complete the statement.
A user wants a Kubernetes deployment to run three separate pods of a web application at one time.

NEW QUESTION # 83
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. Configuration changes must be sent to the pipeline, which then updates the repository.
- B. The webhook call from the code repository did not reach the CI server.
- C. The pipeline must be started manually after the code repository is updated.
- D. The CI server was not configured as a Git remote for the repository.
Answer: B
Explanation:
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."
