- D. IP address: 192.168.20.30 Subnet Mask: 255.255.255.240 Default Gateway: 192.168.20.17
- E. IP address: 192.168.20.30 Subnet Mask: 255.255.255.240 Default Gateway: 192.168.20.25
Answer: Option C.
Explanation:
A /29 network has only 8 IP addresses, of which 6 are usable IP addresses. This means that 192.168.20.24 represents the network, 192.168.20.25 is the first usable IP address, 192.168.20.30 is the last usable IP address and 192.168.20.31 is the broadcast address on the network. Another way to write /29 is
255.255.255.248, so the answer is C.
