ITPEC FE Morning October 2020 Question 32
ITPEC FE Morning October 2020 — Question 32 of 80
DNS (Domain Name System) — associates domain or host names with IP addresses.
DNS resolves human-readable names like example.com into IP addresses like 93.184.216.34.
Why not others:
- (a) — describes DHCP (assigns IP addresses from a pool)
- (c) — describes NAT (converts private IPs to global IPs)
- (d) — describes RPC (calls remote programs by name without knowing the server IP)
Key rule: DNS = name ↔ IP mapping. DHCP = IP assignment. NAT = private ↔ public IP translation.
