QUESTION 3 2.4-7 The local DNS server. Check all of the phrases below that state a true property of a local DNS server. The local DNS server record for a remote host sometimes different from that of the authoritative server for that host. The local DNS server holds hostname-to-IP translation records, but not other DNS records such as MX records. The local DNS server can decrease the name-to-IP-address resolution time experienced by a querying local host over the case when a DNS is resolved via querying into the DNS hierarchy. The local DNS server is only contacted by local host if that local host is unable to resolve a name via iterative or recursive queries into the DNS hierarchy.
