Which IP service is used to monitor the performance of network devices?

The correct answer is A. SNMP. SNMP (Simple Network Management Protocol) is the standard protocol used to monitor and manage network devices such as routers, switches, servers, and printers. It operates over UDP (ports 161/162) and uses a manager-agent architecture: network management systems (NMS) poll SNMP a

Explanation

SNMP (Simple Network Management Protocol) is the standard protocol used to monitor and manage network devices such as routers, switches, servers, and printers. It operates over UDP (ports 161/162) and uses a manager-agent architecture: network management systems (NMS) poll SNMP agents on devices to collect performance metrics (CPU usage, interface statistics, error rates) and receive traps (alerts) for events. DHCP (B) dynamically assigns IP addresses to hosts - it has no monitoring function. DNS (C) resolves hostnames to IP addresses. NTP (D) synchronizes clocks across network devices, which is important for log correlation but is not a performance monitoring protocol. SNMP is the foundational protocol for network performance visibility and is tested extensively on CCNA and similar certifications.
