A network engineer has finished designing and implementing a new network. What two protocols would they use to gain insight into the network and determine the components that require optimization? (Choose two.)
A. CDP
B. NetFlow
C. ICMP Echo
D. NMAP
E. SNMP
D could also be correct as NMAP (Network Mapper) is designed to scan large networks or even a single host. It is
an open source utility used for network exploration and security audits. Simple Network Management Protocol (SNMP) is a popular protocol for network management. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.
