A network technician needs to establish baseline performance monitoring and secure telemetry for a company's voice-over-IP (VoIP) infrastructure. Which of the following operational measures should the technician implement to effectively monitor audio quality and secure management traffic? (Select TWO).
- Track jitter and latency metrics to identify delay variations that degrade real-time audio quality.Cevap
- Implement SNMPv3 using the authPriv security level to authenticate polling requests and encrypt payload data.Cevap
- CConfigure SNMPv2c community strings to provide packet-level payload encryption for metric data.
- DRequire TCP for all voice streaming payloads to eliminate header overhead and minimize end-to-end delay.
Cevap
The correct measures are tracking jitter and latency metrics to assess audio performance, and deploying SNMPv3 with the authPriv security level to encrypt monitoring traffic and authenticate polling requests.
Tracking jitter and latency measures real-time delivery performance required for VoIP call stability. Configuring SNMPv3 with the authPriv setting guarantees that device monitoring requests are securely authenticated and all telemetry payload data is encrypted over the network.
