- DIP address: 192.168.10.41 subnet mask: 255.255.255.248, default gateway: 192.168.10.46
- EIP address: 192.168.10.254 subnet mask: 255.255.255.0, default gateway: 192.168.10.1

13A company has a network address of 192.168.1.64 with a subnet mask of 255.255.255.192. The company wants to create two subnetworks that would contain 10 hosts and 18 hosts respectively. Which two networks would achieve that? (Choose two.)

20In dotted decimal notation, the IP address [blank_start]172.25.0.126[blank_end] is the last host address for the network 172.25.0.64/26.
- A172.25.0.126
21 Fill in the blank.
In dotted decimal notation, the subnet mask [blank_start]255.255.254.0[blank_end] will accommodate 500 hosts per subnet.
Consider the following range of addresses:
2001:0DB8:BC15:00A0:0000::
2001:0DB8:BC15:00A1:0000::
2001:0DB8:BC15:00A2:0000::
…
2001:0DB8:BC15:00AF:0000::
The prefix-length for the range of addresses is [blank_start]/60[blank_end]- A255.255.254.0
- B/60
22A nibble consists of [blank_start]4[blank_end] bits.
- A4
23Given the network address of 192.168.5.0 and a subnet mask of 255.255.255.224, how many addresses are wasted in total by subnetting each network with a subnet mask of 255.255.255.224?
- A56
- B60
- C64
- D68
- E72
24Refer to the exhibit. Consider a datagram that originates on the PC and that is destined for the web server. Match the IP addresses and port numbers that are in that datagram to the description. (Not all options are used.)
destination IP address -> [blank_start]192.168.2.2[blank_end]
destination port number -> [blank_start]80[blank_end]
source IP address -> [blank_start]192.168.1.2[blank_end]
source port number -> [blank_start]2578[blank_end]
- A192.168.2.2
- B80
- C192.168.1.2
- D2578
