Hey Ruben! I think the answers (a) and (b) are correct. Routers use
the Longest prefix match algorithm
https://en.wikipedia.org/wiki/Longest_prefix_match. Hence, the answer (c)
is incorrect because the 1st interface has the longest prefix match
comparing to the 2nd interface. With the same logic, answer (d) is
incorrect because the 3rd interface has the longest prefix match comparing
to the 2nd interface.

Suppose addresses are 8 bits. Given the following forwarding table:
Prefix? Interface
1011? ? 1
101? ? ? 2
10101? ? 3
0? ? ? ? 4
00? ? ? 5
What range of addresses is forwarded to interface 2 ?
