A network administrator needs to establish a performance monitoring strategy for a critical enterprise WAN link. The requirements state that the solution must securely collect interface baseline utilization counters without exposing management data to sniffing, while also providing flow-level insight into which specific applications and endpoints are consuming bandwidth. Which of the following protocols and configurations should the administrator deploy? (Select TWO.)
- SNMPv3 configured with the authPriv security level to securely poll interface metrics and device health counters.Answer
- IPFIX flow export routed through an encrypted tunnel to provide granular traffic statistics and protocol breakdowns.Answer
- CSNMPv2c using a complex read-only community string to enforce payload encryption across the WAN link.
- DSyslog streaming over UDP port 23 to capture interface byte counts and performance telemetry in real time.
Answer
Deploying SNMPv3 configured with the authPriv security level alongside IPFIX flow export transmitted over an encrypted tunnel.
Complete network performance monitoring requires both metric counter polling and traffic flow analysis. SNMPv3 with authPriv fulfills the requirement for secure, encrypted baseline metric polling, while IPFIX exports granular flow-level metadata for application bandwidth profiling.
Step-by-Step Solution
Key Concept
Combining SNMPv3 authPriv polling with IPFIX flow exporting for comprehensive and secure network performance monitoring.
