A systems administrator needs to configure monitoring for a private cloud environment. The administrator has decided to use SNMP for this task.
The Correct Answer is: D. 161
SNMP (Simple Network Management Protocol) uses UDP port 161 for sending and receiving management and monitoring data between devices and monitoring systems. It's the standard port for querying and receiving updates about device status, performance, and configuration in a networked environment.
Why the other options are incorrect:
A. 53
Port 53 is used by DNS (Domain Name System) for resolving domain names to IP addresses—not for monitoring via SNMP.
B. 123
Port 123 is used by NTP (Network Time Protocol), which synchronizes time across devices. It’s not involved in system monitoring.
C. 139
Port 139 is used by NetBIOS Session Service, often associated with file and printer sharing on Windows networks. It is unrelated to SNMP or cloud monitoring.
