A. Verify that the DNS server address is correct in the DHCP pool.
B. Ping the default gateway to populate the ARP cache.
C. Use the tracert command on the DHCP client to first determine where the problem is located.
D. Clear all DHCP leases on the router to prevent address conflicts.
E. Issue the ipconfig command with the /release and /renew options in a command window.

 

Answer: E[/am4show]

Question 3

[am4show have=’p2;’]You have configured the host computers on a campus LAN to receive their DHCP addresses from the local router to be able to browse their corporate site. Which statement about the network environment is true?

A. It supports a DNS server for use by DHCP clients.
B. Two host computers may be assigned the same IP address.
C. The DNS server must be configured manually on each host.
D. The domain name must be configured locally on each host computer.

 

Answer: A[/am4show]

Explanation

The local router in this case is called a DHCP server. The main purpose of a DHCP server is to assign IP addresses to the clients. Besides that, a DHCP server can also specify the IP address of the DNS server and specify the domain name for the clients.
