Troubleshooting Name Resolution Flashcards
CorpServ is a small company with 14 client systems and a network printer. Because there are only a limited
number of networked systems, you decide to use APIPA addressing for the network. With APIPA configured,
all systems are able to communicate with each other but you are having trouble configuring Internet access.
What is the likely cause of the problem?
All client systems must be rebooted.
The DNS server is unavailable to resolve Internet hostnames.
The default gateway is not set on the client systems.
The default gateway is not set on the server.
Private addresses cannot directly communicate to hosts outside the local subnet.
Private addresses cannot directly communicate to hosts outside the local subnet.

You are implementing a DHCP server for your segment. Your segment’s IP address is 192.168.1.0. Your
default gateway address is 192.168.1254. Your DNS server address is 192.168.1.1. Your default gateway is
configured as a NAT router to translate addresses between network segments.
You configured the 03 Router option on your DHCP server so it can deliver the IP address of the default
gateway to workstations. After configuring your workstations to get their IP addressing information
dynamically, your users complain that they are unable to access web sites on the Internet.
How can you resolve this problem?
You must configure your DHCP server with an option that delivers the IP address of the default worldwide web server (Option 72).
You must implement a BOOTP server instead of a DHCP server.
You must configure Automatic Private IP Addressing (APIPA) on each workstation using default settings.
an option that enables IP forwarding (Option 19).
You must configure your DHCP server with an option that delivers the IP address of the DNS server
You can’t implement a DHCP server in conjunction with a NAT router.
You must configure your DHCP server with an option that delivers the IP address of the DNS server
(Option 06).
After installing a new DHCP server on the network, you need to verify that network devices are receiving IP
addressing via DHCP. You reboot a Windows XP client system and using the ipconfig command, receive the
following information:

Which of the following statements are true? (Select two).
The client system is unable to reach the DHCP server.
The Default gateway address needs to point to the DHCP server.
The network subnet mask is incorrect.
The client system is configured to use DHCP.
The network is configured to use static IP addressing.
DHCP is disabled on the client system.
The client system is unable to reach the DHCP server.
The client system is configured to use DHCP.
You are troubleshooting a network connectivity issue on a Unix system. You are able to connect to remote
systems by using their IP address, but unable to connect using the hostname. You check the TCP/IP
configuration, and note that a DNS server IP address is configured.
You decide to run some manual resolution queries to ensure that the communication between the Unix
system and the DNS server are working correctly. Which utilities can you use to do this? (Choose two.)
dig
nslookup
traceroute
tracert
dig
nslookup
A user reports that he can’t browse to a specific Web site on the Internet.
From his computer, you find that a ping test to the Web server succeeds. A trace route test shows 17 hops to
the destination Web server.
What is the most likely cause of the problem?
Incorrect DNS server address
Incorrect subnet mask value
Duplicate IP addresses
Incorrect default gateway address
Incorrect DNS server address
Mary calls to tell you that she can’t connect to an intranet server called WebSrvl. From her computer, you
ping the server’s IP address. The ping test is successful. Which tool would you use on her workstation next to
troubleshoot the problem?
nslookup
tracert
nbtstat
arp
netstat
nslookup
