Show answer & explanation
Correct answer: B
Correct answer: DHCP (ii) and BOOTP (iii) assign dynamic IP addresses.
Explanation:
DHCP (Dynamic Host Configuration Protocol): Assigns IP addresses dynamically to hosts, provides address leasing and additional configuration options (gateway, DNS, etc.). It is the modern standard for dynamic IP assignment.
BOOTP (Bootstrap Protocol): An older protocol that also provided dynamic addressing for hosts (commonly used for diskless workstations). Largely superseded by DHCP but historically used for IP assignment.
POP (Post Office Protocol): An email retrieval protocol; it does not assign IP addresses.
SNMP (Simple Network Management Protocol): Used for network management and monitoring; it does not perform IP assignment.
ICMP (Internet Control Message Protocol): Used for control messages and diagnostics (for example, ping); it does not assign IP addresses.
Therefore, only DHCP and BOOTP assign dynamic IP addresses.
