I would argue D is the correct answer. It allows you to check host name to IP resolution. Use answer A to check which DNS server you are using. Use B to check Rack ID and Rack Name. Use C to (possibly) check which IP addresses are configured. Possibly: because I am unsure if `ifconfig` is part of SLES.
