What range of ports can either be used by TCP to identify the requested service on the destination device or as a client source port?
- 0 to 1023
- 0 to 49151
- 1024 to 49151
- 49152 to 65535
Explanation: Well-known ports (numbers 0 to 1023) are commonly used to request a connection to that specific port, and its associated service. Registered ports (numbers 1024 to 49151) are assigned to user processes or applications. These processes are primarily individual applications that a user has chosen to install, rather than common applications that would receive a well-known port number. When not used for a server resource, these ports can also be dynamically selected by a client as its source port. Dynamic or private ports (numbers 49152 to 65535) are most often used to identify the client application during communication.
