CompTIA Server+ (SK0-005) — Question 257

A technician is working on a Linux server and is trying to access another server over the network. The technician gets server not found messages when trying to execute ping servername but no error messages when using ping servername.domain.com. Which of the following should the technician do to resolve the error?

Answer options

• A. Configure the domain search variable.
• B. Change the permissions on resolv.conf.
• C. Configure the DNS address.
• D. Modify nsswitch.conf.

Correct answer: A

Explanation

The correct answer is A because configuring the domain search variable allows the system to append the domain suffix to unqualified domain names, enabling successful pings to 'servername'. Options B and C are not directly related to resolving the issue of the unqualified name, while D pertains to name resolution services but does not specifically address the domain search configuration.
