300-435 Question 114
Single answerYou are tasked with configuring an automation workflow for a Cisco network where the system should only send notifications when a specific interface status changes (e.g., from 'up' to 'down'). Which method would best align with this requirement in a scalable manner?
- A
Using a continuous polling script that checks the interface status every 5 seconds
- B
Leveraging an on-change subscription model to trigger notifications
- C
Configuring a cron job to periodically execute interface status checks
- D
Implementing a manual check process where administrators monitor the interface status
Show answer and explanation
Correct answer: B
Explanation
The on-change subscription model is the best solution for this scenario as it enables real-time notifications only when a change occurs, minimizing resource consumption and ensuring timely updates. This aligns with the automation and scalability requirements for Cisco Enterprise Solutions.
- A. Incorrect.
This approach is resource-intensive and not efficient for scalable solutions. Polling continuously consumes unnecessary CPU and bandwidth, especially in large networks.
- B. Correct.
An on-change subscription model is designed to monitor changes in real-time and send notifications only when changes occur, making it an efficient and scalable solution.
- C. Incorrect.
While cron jobs can automate periodic checks, they are not real-time and may miss events that happen between execution intervals.
- D. Incorrect.
Manual monitoring does not meet the automation requirement and is prone to human error, making it unsuitable for scalable solutions.
