Question
Which of the following files would a junior systems administrator check to verify DNS server settings?
Options
- A/etc/network
- B/etc/rsolveconf
- C/etc/nsswitch,conf
- D/etc/hosts
Explanation
This question asks for the standard Linux file that contains DNS resolver configuration.
Common mistakes.
- A. /etc/network is a directory often used for network interface configuration scripts, not DNS resolver settings directly.
- C. /etc/nsswitch.conf configures the Name Service Switch (NSS) which determines the order in which sources are queried for information, but it doesn't specify the DNS server IPs themselves.
- D. /etc/hosts maps hostnames to IP addresses locally on the system, bypassing DNS for those specific entries, but it does not specify the DNS servers to be used.
