Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureEasy
A network engineer is deploying a new service that requires precise, deterministic measurements of network performance metrics like jitter and packet loss between two critical points in the network. The measurements need to be active and on-demand. Which feature should the engineer implement?
- AIP Service Level Agreement (IP SLA)
- BSyslog
- CNetFlow
- DSNMP
Show answer & explanationAnswer & explanation
Correct answer: A. IP Service Level Agreement (IP SLA)
IP SLA (IP Service Level Agreement) is designed to actively monitor network performance by generating and analyzing traffic to measure metrics like jitter, latency, and packet loss. This fits the requirement for precise, deterministic, and active measurements.
Why the other options are wrong
- B. Syslog collects log messages for events and errors, not performance statistics.
- C. NetFlow monitors existing traffic flows but does not actively generate traffic for performance measurement.
- D. SNMP collects device statistics and status, but not active performance metrics like jitter between two points.
IP Service Level Agreement (IP SLA)
A Cisco IOS feature that allows for active monitoring of network performance by generating and analyzing traffic to measure metrics like jitter, latency, and packet loss.
- Actively generates synthetic traffic.
- Measures network performance metrics (e.g., jitter, latency, packet loss).
- Can be used for path monitoring and troubleshooting.
Memory trick: IP SLA actively checks, not passively watches.
