A network operations team is upgrading the enterprise monitoring architecture to address bandwidth degradation, security compliance, and service level agreement (SLA) tracking across site-to-site WAN links. Match each network performance monitoring technology or protocol on the left with the specific operational monitoring requirement it directly satisfies on the right.
- NetFlow / IPFIX Flow Record TelemetryQuantifying top talkers, protocol breakdown, and interface bandwidth utilization without storing packet payloads
- SNMPv3 with authPriv Security LevelSecurely polling switch CPU, memory, and interface error counters over an encrypted and authenticated management connection
- IP SLA Active Synthetic ProbingContinuously measuring end-to-end latency, jitter, and packet loss metrics to validate real-time VoIP performance
- Full Packet Capture via Physical Network TAPInspecting exact bit-level TCP windowing behavior, frame errors, and unencrypted application payload contents
Cevap
NetFlow / IPFIX matches with quantifying top talkers and protocol breakdown without payload storage; SNMPv3 authPriv matches with securely polling system health metrics over encrypted connections; IP SLA active probing matches with measuring latency, jitter, and loss for VoIP SLAs; Full Packet Capture matches with inspecting exact bit-level TCP behavior and raw payload contents.
Each technology satisfies a distinct performance monitoring requirement: NetFlow/IPFIX aggregates layer 3/4 header stats for top talkers without storing payloads; SNMPv3 authPriv enforces encryption and authentication for device health polling; IP SLA injects synthetic probes to calculate delay, jitter, and loss for voice SLAs; and full packet capture duplicates physical traffic for low-level TCP and payload analysis.
