CompTIA A+ Core 1 (220-1201) — Question 79

Which of the following network services is used to assign an IP address to a network host?

Answer options

• A. DHCP
• B. DNS
• C. LDAP
• D. SMTP

Correct answer: A

Explanation

DHCP (Dynamic Host Configuration Protocol) is specifically designed to assign IP addresses to devices on a network automatically. DNS (Domain Name System) is used for resolving domain names to IP addresses, LDAP (Lightweight Directory Access Protocol) is for directory services, and SMTP (Simple Mail Transfer Protocol) is for email transmission, making them unsuitable for IP address assignment.
