Q33Network
A network architect needs to propose a scalable network-monitoring solution in which data is repeatedly collected from network devices. The solution must use a push model and provide near-real-time access to operational data. Which technology must be used to satisfy these requirements?

D is correct
A. CLI-based scripting: This method uses scripts to pull data from network devices via their command-line interfaces (CLIs). While it can be used for data collection, it's not as scalable or real-time as streaming telemetry.
B. Logging: Logging usually means storing log data produced by network devices. While it can provide useful information, it is not inherently a real-time push model and may not satisfy the requirement for close to real-time access to operational data.
C. SNMPv3: SNMP (Simple Network Management Protocol) is a widely used protocol for monitoring and managing network devices. SNMPv3 does support data retrieval, but it uses a pull model (where the monitoring system requests data from devices) rather than a push model, which may not provide access as close to real-time as streaming telemetry does.
