A company is using several network applications that require high availability and responsiveness, such that milliseconds of latency on network traffic is not acceptable. An engineer needs to analyze the network and identify ways to improve traffic movement to minimize delays. Which information must the engineer obtain for this analysis?
A. total throughput on the interface of the router and NetFlow records
B. output of routing protocol authentication failures and ports used
C. running processes on the applications and their total network usage
D. deep packet captures of each application flow and duration
Its A. The questions asks for a “profiling” of the network to identify a way to improve the traffic movement, and the way to make that profiling is by studying the network throughput by analyzing network packets (For example, with Wireshark) and the network Flows (With NetFlow or IPFIX) Reference: Official Certification Guide , Cisco CyberOps Associate CBROPS 200-201 page 419 by Omar Santos
