DHCP Questions 2

Question 1

Explanation

The command “show ip dhcp conflict” displays address conflicts found when addresses are offered to the client. Below is an example:

Question 2

Question 3

Question 4

Question 5

Explanation

In the DHCP pool we need to configure a default gateway (via the “default-route …” command) for the DHCP clients to communicate with outside subnets.

Question 6

Question 7

Explanation

In this case the printer is statically assigned an IP address so we have to make sure DHCP server does not assign the same IP address to another device. We can configure the DHCP server with the command “ip dhcp excluded-address <ip-address>” (suppose it is a Cisco device).

    Which command can you enter to display duplicate IP addresses that the DHCP server assigns?
    A. show ip dhcp conflict 10.0.2.12
    B. show ip dhcp database 10.0.2.12
    C. show ip dhcp server statistics
    D. show ip dhcp binding 10.0.2.12

    Can some tell me why the answer A is correct .
    I think answer D is correct because in the new iOS Version 15.2(4)S5, there is no option to enter the IP address after the command sh ip dhcp conflict (***).

    @sachu good observation. none of these commands allow to enter specific ip address

    @9tut could you please specify why it is correct?

    thanks
