A municipal AI factory NOC finds that blind SNMP polling misses microbursts on Spectrum-X. What should they enable?
Select an answer to reveal the explanation.
Short Explanation
SNMP byte counters polled every five minutes will miss Spectrum-X microbursts the way a slow security camera misses a sprint. Turn on WJH and in-band telemetry so the NOC actually sees those short congestion hits.
Full Explanation
A municipal AI factory NOC that finds blind SNMP polling misses microbursts on Spectrum-X should enable WJH and in-band telemetry rather than relying only on coarse SNMP polling for microbursts. AI Ethernet microbursts are short and intense; minute-scale SNMP samples often average them away. WJH captures real-time discard/congestion events, and in-band telemetry exposes path congestion with the fidelity Spectrum-X RoCE fabrics need. For a city AI factory, that upgrade in observability is how the NOC stops flying blind between SNMP polls.
Polling interface byte counters via SNMP at five-minute intervals to track average buffer utilization fails because five-minute SNMP averages smooth over microbursts, leaving the NOC blind to the short congestion spikes that WJH and in-band telemetry capture. Streaming drop and queue counters via gNMI telemetry using one-second export intervals fails because generic queue counters still aggregate bursts and lack WJH's real-time, per-packet discard and congestion context on Spectrum-X. Enabling adaptive routing with DCQCN tuning to rebalance elephant flows across Spectrum-X links fails because it changes traffic behavior rather than giving the NOC the observability needed to see microbursts.
Exam caveat: WJH and in-band telemetry complement SNMP; they do not always replace every legacy poll for device health, but they are required for microburst-class Spectrum diagnosis. Operational check: deploy or enable WJH and in-band telemetry on the municipal Spectrum-X fabric, compare a known microburst window against SNMP charts to show what SNMP missed, alert on WJH discard signatures, and update NOC runbooks so Spectrum AI incidents start with high-fidelity fabric telemetry.
