A service provider is redesigning its network monitoring to better understand user experience for a new cloud-based VoIP service. The operations team currently relies on SNMP polling of interface counters and periodic CLI checks. They want to detect subtle performance degradation before users complain. Which approach best aligns with the goal of moving from visibility to observability?

Deploy model-driven telemetry streaming from network devices to a centralized analytics platform, correlating with application performance data.

Use NetFlow exports from edge routers to analyze traffic patterns and identify top talkers for capacity planning.

Increase SNMP polling frequency to every 30 seconds and add more MIB variables to capture detailed interface statistics.

Implement a custom syslog aggregation system to collect all device logs and generate alerts based on keyword matching.

A university network team is deploying a new wireless network and wants to ensure that the monitoring system can provide both real-time alerts and historical reporting for compliance audits. They have a limited budget and prefer to use existing infrastructure. Which solution is most suitable?

Use only the wireless controller's built-in reporting and alerts.

Deploy an open-source monitoring stack (e.g., Prometheus and Grafana) on existing servers with long-term storage.

Purchase a commercial monitoring platform with a high license fee and dedicated hardware.

Implement a manual log collection process using spreadsheets.

In operational design, what is the role of alerting in a visibility and observability strategy?

To automatically fix network issues

To store historical data for compliance

To replace the need for dashboards

To notify operators of conditions that require attention

What is the primary purpose of integrating visibility and observability data with network management systems?

To enable automated correlation and alerting across multiple data sources

To reduce the amount of data collected from the network

To simplify the network design by reducing the number of devices

To replace the need for dedicated monitoring tools

What is the main advantage of passive monitoring over active monitoring?

It provides more accurate latency measurements

It does not introduce additional traffic into the network

It can test the network from the user's perspective
