   A network engineer is configuring streaming telemetry from Nexus switches to a custom collector that only supports JSON encoding over HTTP. The engineer needs to select a data model and transport that are compatible with these constraints. Which combination should they choose?

   • AYANG model with gRPC and GPB encoding
   • BCLI-based show commands with HTTP and XML encoding
   • CYANG model with HTTP and JSON encoding
   • DMIB objects with HTTPS and GPB encoding

   Which statement correctly contrasts streaming telemetry with traditional polling-based monitoring?

   • AStreaming telemetry requires more bandwidth than polling because it always sends all data, even when nothing changes.
   • BStreaming telemetry uses a push model with lower latency, while polling uses a pull model that can miss transient events.
   • CPolling is more efficient than streaming telemetry because it only sends data when changes occur.
   • DStreaming telemetry is pull-based, while polling is push-based.

   An engineer is configuring streaming telemetry on a Nexus switch to monitor interface state changes. They want to receive an update immediately when an interface goes down or comes up, but they do not need periodic updates. Which subscription type should they configure?

   • APeriodic subscription with a 30-second interval
   • BSNMP trap configuration
   • COn-change subscription
   • DA combination of periodic and on-change

   A data center team currently uses SNMP polling every 5 minutes to monitor interface utilization on their Nexus switches. They need to detect micro-bursts that cause intermittent packet drops, and they want to reduce the load on the management station. Which approach best addresses their requirement?

   • AImplement model-driven streaming telemetry with on-change and periodic subscriptions to a collector
   • BConfigure SNMP traps for interface errors and increase polling frequency to 30 seconds
   • CUse SNMP bulk retrieval to collect all interface counters at once every minute
   • DEnable NetFlow on the switches and analyze flow records for utilization trends

   A data center team is setting up a streaming telemetry pipeline to monitor fabric health. They need to collect data from multiple switches, store it for historical analysis, and generate alerts when anomalies are detected. Which architecture best supports this requirement?

   • ASwitches stream to a message broker, which is consumed by a custom application that stores data in flat files
   • BSwitches send data to a syslog server, which forwards to a log analyzer
   • CSwitches stream directly to a time-series database, which is queried by an alerting system
   • DA central poller collects data via SNMP and stores it in a spreadsheet
