DNS (Domain Name System) is the technology responsible for matching a name to an IP address of an application running on a host. When a user types a domain name into a browser, DNS translates that domain name into the corresponding IP address, enabling the user's device to connect to the server hosting the application.

For the distributed application developed using the Cisco Intersight SDK to communicate with the Intersight API, the traffic needs to be allowed through the firewall. The correct URL and port that need to be provided to the firewall administrator are svc.intersight.com on port 443. Port 443 is the standard port for HTTPS traffic, which ensures secure communication between the application and the Intersight server.

Simple Network Management Protocol (SNMP) is widely used for network management and monitoring. It allows administrators to monitor and manage network devices such as routers, switches, and servers by collecting information on device performance, status, and errors.

SNMP: Provides a framework for exchanging management information between network devices. It helps in monitoring network performance, detecting faults, and configuring devices remotely.

Other Protocols:

DHCP: Used for dynamic IP address assignment.

DNS: Resolves domain names to IP addresses.

NTP: Synchronizes time across network devices.
