Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureHard
A network engineer is deploying a new service that requires precise, deterministic measurements of end-to-end latency and jitter between two network devices. The measurements need to be active, synthetic, and able to simulate various types of network traffic (e.g., VoIP, video). The engineer wants to proactively monitor performance and trigger alerts if thresholds are exceeded. Which Cisco technology is best suited for this purpose?
- ASNMP (Simple Network Management Protocol)
- BSyslog
- CIP SLA (IP Service Level Agreement)
- DNetFlow
Show answer & explanationAnswer & explanation
Correct answer: C. IP SLA (IP Service Level Agreement)
IP SLA (IP Service Level Agreement) is a Cisco technology that performs active monitoring by generating synthetic traffic to measure network performance metrics such as latency, jitter, and packet loss. It can simulate various traffic types and trigger events or alerts when performance thresholds are violated, making it ideal for proactive monitoring of critical services.
Why the other options are wrong
- A. SNMP collects device health and interface statistics, not active end-to-end performance metrics for services.
- B. Syslog collects event messages, not performance measurements.
- D. NetFlow collects traffic flow statistics, not active synthetic measurements of latency and jitter.
IP Service Level Agreement (IP SLA)
A Cisco technology that actively monitors network performance by generating and analyzing synthetic traffic to measure metrics such as latency, jitter, packet loss, and connectivity.
- Performs active, synthetic measurements.
- Can simulate various application traffic types (e.g., ICMP echo, UDP jitter, HTTP).
- Used for proactive monitoring, troubleshooting, and verifying QoS policies.
