Which DNS record type specifies authoritative information about a DNS zone such as a primary name server, email address of the domain administrator, and domain serial number?1 pointSOA - Start for Authority:NS - Name Server:PTR - Pointer:CNAME - Canonical Name:

Sure, let's break down the question step by step to find the correct DNS record type that specifies authoritative information about a DNS zone.

1. Understanding DNS Record Types:

   • SOA (Start of Authority): This record provides authoritative information about a DNS zone. It includes details such as the primary name server, the email address of the domain administrator, the domain serial number, and other important information.
   • NS (Name Server): This record specifies the authoritative name servers for the domain.
   • PTR (Pointer): This record is used for reverse DNS lookups, mapping an IP address to a domain name.
   • CNAME (Canonical Name): This record is used to alias one name to another, essentially redirecting one domain name to another.

2. Analyzing the Question:

   • The question asks for the DNS record type that specifies authoritative information about a DNS zone, including the primary name server, email address of the domain administrator, and domain serial number.

3. Matching the Description:

   • The description provided in the question matches the details of the SOA (Start of Authority) record.

4. Conclusion:

   • The correct DNS record type that specifies authoritative information about a DNS zone, such as a primary name server, email address of the domain administrator, and domain serial number, is the SOA (Start of Authority) record.

So, the answer is: SOA - Start of Authority

The DNS record type that specifies authoritative information about a DNS zone, such as a primary name server, email address of the domain administrator, and domain serial number is SOA - Start of Authority.
