A DNS _____________ creates, maintains and updates the zone file.
A DNS _____________ creates, maintains and updates the zone file.
The correct option is A Primary
A DNS Primary creates,
maintains and updates the zone file.
DNS zone transfer, also
sometimes known by the inducing DNS query type AXFR, is a type of DNS
transaction. It is one of the many mechanisms available for administrators to
replicate DNS databases across a set of DNS servers. ... The portion of the
database that is replicated is a zone.
Primary DNS zone is
hosted in the Primary DNS Server. Secondary DNS Zone: A Secondary DNS Zone is
Read-Only copy of a Primary Zone, or another Secondary Zone, kept in a
Secondary DNS Server. A Secondary DNS Zone is used to reduce the load on
Primary DNS Servers and also for preventing single point of failure.
A DNS zone is a subset,
often a single domain, of the hierarchical domain name structure of the DNS.
The zone file contains mappings between domain names and IP addresses and other
resources, organized in the form of text representations of resource records
(RR).
The connection is
established between the DNS Server to transfer the zone data and Source and
Destination DNS Servers will make sure that data is consistent by using TCP ACK
bit. A client computer will always send a DNS Query using UDP Protocol over
Port 53.
