A network administrator is setting up a performance monitoring and telemetry strategy across an enterprise network that supports real-time voice communications and core infrastructure devices. The design requires secure polling of switch hardware metrics alongside precise measurement of packet delay variability for voice streams. Which of the following configuration options and metric analysis practices should the administrator implement? (Select TWO.)
- Implement SNMPv3 configured with the authPriv security level to ensure both cryptographic authentication and payload encryption during switch metric polling.Answer
- BDeploy SNMPv2c using complex community strings to encrypt CPU and memory baseline metrics in transit across the management VLAN.
- Monitor jitter metrics using IPFIX or NetFlow flow records transported via UDP to assess packet arrival time variation across real-time voice streams.Answer
- DConfigure IPFIX flow collection over TCP port 161 to guarantee reliable delivery of flow records without packet loss.
Answer
The correct selections are implementing SNMPv3 with the authPriv security level for encrypted hardware polling, and monitoring jitter metrics using IPFIX or NetFlow flow records over UDP to evaluate delay variation in voice streams.
Configuring SNMPv3 with authPriv satisfies enterprise security standards by authenticating the session and encrypting metric payloads. Additionally, tracking jitter metrics via IPFIX/NetFlow transported over UDP enables network engineers to diagnose delay variation affecting latency-sensitive traffic such as VoIP.
