The correct answer is: C. POP3
POP3 (Post Office Protocol version 3) is an application-layer Internet standard protocol for accessing e-mail. POP3 is a client-server protocol, where the client (user’s computer) connects to the server (mail server) and requests to download new emails. The server then transfers the emails to the client, which can then read them offline.
SNMP (Simple Network Management Protocol) is a network management protocol that allows network administrators to remotely monitor and manage devices on a network. ICMP (Internet Control Message Protocol) is a network protocol that is used to send error messages and control messages between hosts on a network. DHCP (Dynamic Host Configuration Protocol) is a network protocol that allows a server to automatically assign IP addresses to devices on a network.
POP3 is the only protocol that allows a workstation to dynamically access mail drops on a server host in a useful manner. The other protocols are not used for this purpose.
