A large enterprise is deploying a new data center fabric and needs to monitor network health with minimal impact on the control plane. They require sub-second visibility into interface utilization and queue drops. Which data collection method is most appropriate?

Periodic CLI parsing of 'show interface' output every minute.

Model-driven telemetry using gRPC with a subscription to interface statistics.

NetFlow export of all traffic flows for analysis.

SNMP polling every 5 minutes for interface counters.

When selecting a data collection method for network assurance, which factor is most important to consider?

The cost of the management platform

The vendor of the network devices

The type of data needed and the required granularity and latency

A cloud provider is designing a monitoring solution for a multi-tenant environment. They need to collect performance data from virtual network functions (VNFs) and physical infrastructure, but they must ensure that tenant data is isolated. Which approach is most appropriate?

Use a single shared telemetry stream and rely on the analytics platform to filter data per tenant.

Use model-driven telemetry with separate subscriptions per tenant and role-based access control (RBAC) on the collector.

Use CLI scraping on each VNF and store data in separate files per tenant.

Collect all data via SNMP and store it in a common database without tenant tagging.

How do visibility and observability complement each other in network design?

Visibility provides the raw data, and observability provides the context and insight needed to understand and troubleshoot the network.

Visibility is achieved through SNMP, while observability is achieved through streaming telemetry.

Visibility is used for security monitoring, while observability is used for performance monitoring.

Visibility is a design-time activity, while observability is a runtime activity.
