Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2AutomationMedium
A network administrator needs to automate the process of collecting operational data from multiple Cisco devices at regular intervals and sending it to a central monitoring system. This data includes interface statistics, CPU utilization, and routing table changes. The administrator wants to use a push-based mechanism for efficiency. Which technology is best suited for this requirement?
- ANETCONF <get>
- BSNMP Polling
- CModel-Driven Telemetry (MDT)
- DSyslog
Show answer & explanationAnswer & explanation
Correct answer: C. Model-Driven Telemetry (MDT)
Model-Driven Telemetry (MDT) uses YANG data models to stream operational data from network devices to collectors. Unlike traditional pull-based methods like SNMP polling or NETCONF <get>, MDT is push-based, offering higher frequency, granular data collection, and efficient data transfer.
Why the other options are wrong
- A. NETCONF <get> is a pull-based request for current state data, not a continuous push stream.
- B. SNMP Polling is a pull-based mechanism, less efficient for high-frequency, granular data collection.
- D. Syslog sends event messages and logs, not structured operational data streams for continuous monitoring.
Model-Driven Telemetry (MDT)
A push-based mechanism that streams operational data from network devices to collectors using YANG data models, offering high-frequency and granular data collection.
- Push-based data delivery.
- Uses YANG data models for structured data.
- Supports high-frequency and granular data collection.
- More efficient than traditional polling for real-time monitoring.
Memory trick: Telemetry is like a real-time data stream, always pushing fresh info.
