Which three steps will help determine the cause of DNS name resolution failure?

Correct Answer: A,B,F
Explanation/Reference:
Explanation:
Check DNS
* (A) Check whether DNS is configured on your client by verifying that a non-empty /etc/resolv.conf file exists.
* (F) If /etc/resolv.conf does not exist or is empty, check that your DHCP server is providing DNS server information to the client:
# /sbin/dhcpinfo DNSserv
If this command returns nothing, the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct this problem.
* (B) If an /etc/resolv.conf file exists and is properly configured, check for the following possible problems and contact your system administrator for resolution:
** The DNS server might not be resolving your IPS repository server name.
