Question: 1 / 400

What does a Start of Authority (SOA) record identify in DNS?

The IP address of a server

The primary name server for a zone

The Start of Authority (SOA) record is crucial in the Domain Name System (DNS) as it holds vital information about a specific domain's DNS zone. It primarily identifies the primary name server for that zone, which is responsible for managing the zone's DNS records. This primary name server is the authoritative source for the domain, meaning it holds the most reliable and updated data concerning the domain's records.

In addition to designating the primary name server, the SOA record includes information such as the email address of the domain administrator, the serial number for the zone which helps with versioning, and timers for refreshing and retrying, among other details. However, the key function and the answer to the question is the identification of the primary name server, which serves as the main point of reference for managing DNS queries for that domain.
