A systems administrator needs to configure monitoring for a private cloud environment. The administrator has decided to use SNMP for this task.
Which of the following ports should the administrator open on the monitoring server's firewall?
Correct Answer: D
Port 161 is the default port used by Simple Network Management Protocol (SNMP) to communicate with network devices and collect information about their status, performance, configuration, and events. Opening port 161 on the monitoring server's firewall will allow SNMP traffic to pass through and enable monitoring for a private cloud environment. If port 161 is closed or blocked, SNMP traffic will be denied or dropped, resulting in a failure to monitor the network devices.
