Which file on client4.bigcorp.com is misconfigured and must be modified to correct the user’s issue?
You receive a HelpDesk ticket from a user who is unable to access the host server6.bigcorp.com from the workstation client4.bigcorp.com. The user has issued a ping command and sends you the output:
% ping server6.bigcorp.com
ping: unknown host server6.bigcorp.com
Big Corp has recently transitioned from using DNS. It now uses LDAP exclusively and has decommissioned all of their internal DNS servers. With the exception of the primary LDAP server, no client has access to a DNS server.
The client4.bigcorp.com was reconfigured to be an LDAP client, as were all other hosts in the department. A check of the contents of the /etc/inet/hosts file on client4.bigcorp.com reveals that it does NOT contain an entry for server6.bigcorp.com. You discover that all of the other systems in the department can access server6.bigcorp.com, even though they do NOT contain an /etc/inet/hosts entry for server6.bigcorp.com.
You run the nslookup command on client4.bigcorp.com and receive the following:
# nslookup server6.bigcorp.com ;;
connection timed out; no servers could be reached
When running ldapsearch from client4.bigcorp.com, it returns the correct IP address for server6.big.corp.com.
Which file on client4.bigcorp.com is misconfigured and must be modified to correct the user’s issue?

Why is the loghost alias NOT displayed?
The host aubie has the following entry in its /etc/nsswitch.conf file (unrelated lines are omitted):
hosts: nis [NOTFOUND=return] files
And the following in its /etc/inet/hosts file:
#
# Internet host table
#
127.0.0.1 localhost

Given the output of the following command:
# getent hosts aubie
10.7.8.101 aubie
Why is the loghost alias NOT displayed?

What is a possible explanation for this problem?
A user is unable to access a host using the telnet command on a new workstation. The user provided the following output:
user1@w2100z% telnet sys42.abc.com
sys42.abc.com: node name or service name not known
user1@w2100z% getent hosts sys42.abc.com
user1@w2100z% nslookup sys42.abc.com
Server: dns.abc.com
Address: 192.168.224.10#53
Name: sys42.abc.com
Address: 192.168.222.15
user1@w2100z% grep sys42 /etc/hosts
user1@w2100z%
The user is able to access sys42 from an old workstation without issue. What is a possible explanation for this problem?
