A network administrator needs to establish a comprehensive network performance monitoring strategy across remote branch routers. The solution must securely collect hardware state metrics (such as CPU utilization and interface counters) while also capturing granular flow-level statistics (such as packet loss and jitter) for latency-sensitive applications. Which TWO performance telemetry mechanisms should the administrator implement to fulfill these requirements?
- Deploy SNMPv3 configured with the authPriv security level to poll hardware state metrics and interface telemetry securely.Cevap
- Export IPFIX (IP Flow Information Export) records to analyze per-flow performance parameters such as packet loss and delay variation.Cevap
- CConfigure SNMPv2c using default community strings to collect real-time per-flow packet loss and jitter measurements.
- DUtilize syslog streaming over UDP port 23 to capture continuous metric metrics and calculate per-flow packet timing.
Cevap
The administrator should implement SNMPv3 with authPriv for secure device state monitoring and IPFIX for granular flow-level performance analysis.
The combination of SNMPv3 with authPriv and IPFIX satisfies both requirements. SNMPv3 authPriv guarantees secure, encrypted polling of system hardware counters and interface statistics. IPFIX allows edge devices to export detailed flow records that track timing, packet loss, and jitter for real-time application traffic analysis.
