Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 43

The implementations group has been using the test bed to do a "˜proof-of-concept' that requires both Client 1 and Client 2 to access the WEB Server at
209.65.200.241. After several changes to the network addressing, routing schemes, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address.
Use the supported commands to isolate the cause of this fault and answer the following question.
What is the solution to the fault condition?

Answer options

• A. Under the global configuration, delete the no ip dhcp use vrf connected command.
• B. Under the IP DHCP pool configuration, delete the default -router 10.2.1.254 command and enter the default-router 10.1.4.5 command.
• C. Under the IP DHCP pool configuration, delete the network 10.2.1.0 255.255.255.0 command and enter the network 10.1.4.0 255.255.255.0 command.
• D. Under the IP DHCP pool configuration, issue the no ip dhcp excluded-address 10.2.1.1 10.2.1.253 command and enter the ip dhcp excluded-address 10.2.1.1 10.2.1.2 command. D

Correct answer:

Explanation

The correct answer is D because it addresses the exclusion of IP addresses in the DHCP pool, which can prevent Client 1 from obtaining a valid IP address necessary for communication with the WEB Server. Options A, B, and C do not directly resolve the DHCP address allocation issue affecting Client 1's ability to ping the server.
