Exam CV0-003 topic 1 question 65 discussion

Port 53 is used for the Domain Name System (DNS) service. DNS is responsible for translating domain names (e.g., www.example.com) into IP addresses (e.g., 192.0.2.1) and vice versa. Port 123 is used for the Network Time Protocol (NTP) service. NTP is used for synchronizing the time of networked devices, ensuring accurate timekeeping across systems. It helps maintain synchronization between servers, workstations, routers, switches, and other networked devices. Port 139 is used for the NetBIOS Session Service, which is part of the Server Message Block (SMB) protocol suite. It is commonly associated with file and printer sharing in Windows environments. Port 139 facilitates communication between devices for accessing shared files, directories, and printers over a network. Port 161 is used for the Simple Network Management Protocol (SNMP) service. SNMP is used for monitoring and managing network devices, such as routers, switches, servers, and printers. It allows network administrators to collect information about device status, performance, and configuration through SNMP agents running on managed devices.

wait, we're gonna get port questions?

To enable SNMP monitoring in a private cloud environment, you should open **port 161** on the firewall of the monitoring server. SNMP (Simple Network Management Protocol) uses this port for communication between the monitored devices (in this case, your private cloud resources) and the SNMP manager (the monitoring server). So, the correct answer is **D. 161**.
