Which of the following computer services associates IP network addresses with text-based names in order to facilitate identification and connectivity?
The correct answer is D. DNS. DNS (Domain Name System) is the service that maps human-readable domain names (like example.com) to IP addresses (like 93.184.216.34), allowing users to access resources by name rather than memorizing numeric addresses.

Explanation
DNS (Domain Name System) is the service that maps human-readable domain names (like example.com) to IP addresses (like 93.184.216.34), allowing users to access resources by name rather than memorizing numeric addresses.
The distractors each describe unrelated services:
- LDAP (A) is a directory protocol for authenticating and querying user/resource information in a network directory.
- NTP (B) is the Network Time Protocol, used to synchronize clocks across networked devices.
- DHCP (C) does deal with IP addresses, but it assigns them dynamically to devices - it doesn't translate names to addresses.
Memory tip: Think "DNS = Directory of Name-to-Server addresses." The word Names in DNS (Domain Name System) directly hints at its role in name-to-IP translation. If a question mentions translating names ↔ addresses, DNS is your answer.
