A network administrator needs to monitor the operational status and performance metrics of various network devices (routers, switches, servers) in real-time. They also want to receive immediate alerts if critical thresholds are exceeded. Which protocol is best suited for this purpose?
- ANTP
- BDHCP
- CSNMP
- DDNS
Show answer & explanationAnswer & explanation
Correct answer: C. SNMP
SNMP (Simple Network Management Protocol) is specifically designed for managing and monitoring network devices. It allows administrators to collect data, modify configurations, and receive event notifications (traps) from devices.
Why the other options are wrong
- A. NTP synchronizes device clocks across a network.
- B. DHCP automatically assigns IP addresses to devices.
- D. DNS translates domain names to IP addresses.
SNMP (Simple Network Management Protocol)
SNMP is an application-layer protocol used for organizing and exchanging information between network devices. It enables network administrators to monitor network performance, find and solve network problems, and configure network devices.
- Used for network device management and monitoring.
- Uses agents on devices and a manager for collection.
- Operates on UDP ports 161 (requests) and 162 (traps).
Memory trick: SNMP makes monitoring Simple, Not Managing Painful.
