An enterprise network engineer is analyzing performance degradation across a site-to-site WAN link supporting real-time voice traffic. Network monitoring shows low overall latency, but voice quality suffers from audio artifacts caused by uneven packet delivery intervals. Additionally, organization compliance policies mandate that device metrics gathered from edge routers must support user authentication and payload encryption. Which TWO of the following metrics or protocol configurations should the engineer implement to address these requirements? (Select TWO)
- Analyze packet jitter metrics to measure the variation in arrival delay across voice streams.Cevap
- Implement SNMPv3 using the authPriv security level to secure router telemetry polling.Cevap
- CConfigure SNMPv2c with community strings to encrypt router performance metrics sent across the WAN.
- DConfigure an IPFIX telemetry stream using TCP port 161 to guarantee reliable transport of delay metrics.
Cevap
The engineer must monitor jitter to measure latency variation in voice streams and deploy SNMPv3 with authPriv to encrypt telemetry polling.
Analyzing packet jitter allows engineers to isolate delay variance impacting real-time media streams, while configuring SNMPv3 with authPriv ensures device telemetry is protected using user authentication and AES payload encryption.
