Why each option
DNS resolves human-readable domain names to IP addresses by querying remote name servers. It does not assign addresses or validate logins.
Login validation is handled by authentication protocols such as RADIUS, LDAP, or Kerberos, not DNS.
Address assignment from internal cached tables describes ARP cache behavior or DHCP lease renewal, not DNS.
Address assignment is the function of DHCP, not DNS; DNS resolves names to addresses but does not assign them.
DNS clients communicate with a remote DNS server to perform address resolution - converting fully qualified domain names (FQDNs) into IP addresses. This lookup process is the core function of DNS on any client device, enabling the client to locate network resources by name rather than by IP address.
