| Question 4 |
A router uses the following routing table:
A packet bearing a destination address 144.16.68.117 arrives at the router. On which interface will it be forwarded?
| eth0 | |
| eth1 | |
| eth2 | |
| eth3 |
Question 4 Explanation:
Firstly start with longest mask.
144.16.68.117 = 144.16.68.01110101 AND 255.255.255.224 = 255.255.255.11100000
= 144.16.68.96(Not matching with destination)
Now, take 255.255.255.0
144.16.68.117 AND 255.255.255.0
= 144.16.68.0 (matched)
Hence, option (C) is correct.
144.16.68.117 = 144.16.68.01110101 AND 255.255.255.224 = 255.255.255.11100000
= 144.16.68.96(Not matching with destination)
Now, take 255.255.255.0
144.16.68.117 AND 255.255.255.0
= 144.16.68.0 (matched)
Hence, option (C) is correct.
