Zorluk: OrtaNetwork Performance Monitoring and Metrics

A network administrator is implementing a telemetry and metric collection framework across core edge routers. The management policy mandates cryptographic authentication and payload encryption for device health polling, alongside flow-level traffic analysis to identify bandwidth-intensive applications. Which of the following solutions should the administrator deploy to fulfill these monitoring objectives? (Select TWO.)

  1. SNMPv3 configured with authPriv to encrypt polling traffic and authenticate management requests for hardware metrics.Cevap
  2. IPFIX flow telemetry exported to a centralized collector to analyze protocol distribution and bandwidth consumption per flow.Cevap
  3. C
    SNMPv2c utilizing community strings to supply encrypted payload transmission for device CPU and interface error counters.
  4. D
    Syslog logging configured over TCP port 23 to capture real-time interface throughput and jitter metrics.

Cevap

The administrator should deploy SNMPv3 configured with authPriv for encrypted health polling and IPFIX flow telemetry for tracking application bandwidth consumption.
Deploying SNMPv3 with authPriv satisfies security requirements by providing authenticated and encrypted polling for router CPU, memory, and interface metrics. Implementing IPFIX provides flow-based telemetry to track volume and application-level bandwidth usage across network interfaces.

Adım Adım Çözüm

1
Evaluate secure polling requirements for hardware health metrics.
Identified SNMPv3 with authPriv mode as the only standard SNMP version that enforces both message integrity/authentication and privacy/encryption.
Legacy versions like SNMPv2c transmit data and credentials unencrypted in cleartext.
2
Evaluate traffic flow analysis requirements for application bandwidth consumption.
Selected IPFIX flow telemetry export.
Flow telemetry protocols such as IPFIX gather detailed layer 3/4 metadata to analyze flow-level throughput, top talkers, and protocol breakdowns.
