Which of the following DNS records could be a glue record?

Answer options

• A. ns1.lab A 198.51.100.53
• B. lab NS 198.51.100.53
• C. ns1.lab NS 198.51.100.53
• D. ns1. A 198.51.100.53
• E. ns1.lab GLUE 198.51.100.53

Correct answer: A

Explanation

A glue record is necessary when a name server is located within the zone it is authoritative for. Option A, 'ns1.lab A 198.51.100.53', fits this definition as it provides the IP address of the name server ns1.lab, which is within the lab zone. The other options either do not provide a valid glue record or do not meet the requirements to be classified as such.
