13. You are configuring a Linux DHCP server. You have it setup and working (as Linux clients are getting ip addresses from the DHCP server fine) but some Windows 95 clients are not getting ip addresses properly from your DHCP server. What do you need to do?
A. route add -host 255.255.255.255 dev eth0
B. route add -net 255.255.255.255 dev eth0
C. service dhcp restart
D. touch /var/state/leases
E. Windows 95 is not compatible with a Linux DHCP server.
You answered this question incorrectly
Explanation: Windows 95 insists that the DHCPOFFER messages be sent to 255.255.255.255. Linux will send them to the broadcast address instead. Adding a host entry for the host 255.255.255.255 will trick Linux into working with the Windows 95 clients.

A. /etc/sysconfig/profile B. /etc/sysconfig/profile
C. /etc/bashrc
D. /etc/profile
E. /etc/env
You answered this question incorrectly
Explanation: The /etc/profile script is used for system-wide enviornment variables and startup files. You could also create a new file in /etc/profile.d/ that ends in .sh and set the enviornment variable in there. Keep in mind that not all users will necessarily use bash.
