H12-211 Exam - Question 142


On the interface serial 1/0/1 of RTA, the command "ip address unnumbered interface loopback 0" has been configured.

Which following statements are correct? (Choose two).

Show Answer
Correct Answer: BC

When the command 'ip address unnumbered interface loopback 0' is used, the serial interface 1/0/1 borrows the IP address of the loopback interface but with a /32 subnet to conserve IP addresses. Thus, the IP address of interface serial 1/0/1 is 10.1.1.1/32. This makes option B correct. The unnumbered interface configuration allows the serial interface to operate without a unique IP address, so the route entry 10.1.1.0/24 would exist in RTA’s routing table, meaning option C is also correct.

C option is right. Display Ip routing-table shows interface serial with the route and output interface as loopback 0

I think it will show you with a /32 prefix instead /24
