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. Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols
- C. Leverage machine learning tools to more quickly identify problems m syslog and SNMP data
- D. Identify and capture the key performance indicators that describe the state of the network
Answer: B
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.
