There can only be one domain statement in the resolv.conf file.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the resolv.conf file is a configuration file for DNS resolution on Unix-like systems. It contains information about the domain name servers that the system should use to resolve domain names to IP addresses. Since the file is used for configuring DNS settings, it makes sense that there can only be one domain statement in the file. Having multiple domain statements would create ambiguity and could lead to conflicts in resolving domain names. Therefore, it is correct to say that there can only be one domain statement in the resolv.conf file.Rate this question:
