Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureMedium
A network operations team is implementing a new monitoring solution that requires detailed information about application performance and latency between various network segments. They need to generate synthetic traffic to specific destinations and measure metrics like response time, jitter, and packet loss. Which network service is best suited for this proactive performance monitoring?
- ANetFlow
- BSNMP
- CIP SLA
- DCDP
Show answer & explanationAnswer & explanation
Correct answer: C. IP SLA
IP SLA (IP Service Level Agreements) allows network devices to generate and analyze synthetic traffic to measure performance metrics like jitter, latency, and packet loss. This proactive monitoring is ideal for assessing application performance and network health from an end-to-end perspective.
Why the other options are wrong
- A. NetFlow collects data about actual traffic flows, but does not generate synthetic traffic or directly measure application performance metrics like jitter.
- B. SNMP is for polling device statistics and configuration, not for generating synthetic traffic or measuring end-to-end performance metrics.
- D. CDP (Cisco Discovery Protocol) discovers directly connected Cisco devices, it has no role in performance monitoring.
IP Service Level Agreements (IP SLA)
A Cisco technology that allows network devices to generate and analyze traffic to measure network performance and health proactively.
- Measures metrics like jitter, latency, packet loss, and connection setup times.
- Can be configured for various protocols (e.g., ICMP, UDP, TCP, HTTP).
- Used for network troubleshooting, performance baselining, and verifying QoS policies.
Memory trick: Proactive Performance: IP SLA Tests the Way.
