Which protocol is primarily used to manage and monitor network devices?

• A. Simple Network Management Protocol (SNMP)
• B. Lightweight Directory Access Protocol (LDAP)
• C. Server Message Block (SMB)
• D. Network Time Protocol (NTP)

Answer: (A)

Network device management and monitoring relies on a protocol that lets a central manager talk to agents on routers, switches, and servers to read status, collect performance data, and get alerted to issues. Simple Network Management Protocol provides this capability. It uses managed objects described in MIBs, supports queries like GET and GET-NEXT, can set configuration parameters with SET, and can send asynchronous notifications called traps or informs when something notable happens. This standardization makes it possible to oversee many devices from a single console, automate threshold-based alerts, and perform remote configuration changes. The other listed protocols serve different purposes: LDAP is for directory services information, SMB is for file and resource sharing, and NTP is for time synchronization. While accurate time helps correlate events, SNMP is the one designed for management and monitoring.
