Chapter 8 homework Flashcards
A network engineer is subnetting the 10.0.240.0/20 network into smaller subnets. Each new subnet will contain between a minimum of 20 hosts and a maximum of 30 hosts. Which subnet mask will meet these requirements?
255.255.255.224
How many host addresses are available on the 192.168.10.128/26 network?
62
How many host addresses are available on the 192.168.10.128/26 network?
62
A network administrator has received the IPv6 prefix 2001:DB8::/48 for subnetting. Assuming the administrator does not subnet into the interface ID portion of the address space, how many subnets can the administrator create from the /48 prefix?
65536
Refer to the exhibit. Which two network addresses can be assigned to the network containing 10 hosts? Your answers should waste the fewest addresses, not reuse addresses that are already assigned, and stay within the 10.18.10.0/24 range of addresses. (Choose two.)
Refer to curriculum topic: 8.1.5
Addresses 10.18.10.0 through 10.18.10.63 are taken for the leftmost network. Addresses 192 through 199 are used by the center network. Because 4 host bits are needed to accommodate 10 hosts, a /28 mask is needed. 10.18.10.200/28 is not a valid network number. Two subnets that can be used are 10.18.10.208/28 and 10.18.10.224/28.
What are two benefits of subnetting networks?
- reducing the size of broadcast domains
- grouping devices to improve management and security
what is the network address and broadcast address for subnet IP address 192.168.10.77/28
network 192.168.10.64/28
Broadcast 192.168.10.79/28
dual stack
The IPv4 packets and IPv6 packets coexist in the same network.
translation
IPv6 packets are converted into IPv4 packets, and vice versa.

A network administrator subnets the 192.168.10.0/24 network into subnets with /26 masks. How many equal-sized subnets are created?
4
2^2=4
