Checkpoint Exam: The Internet ProtocolConsider the group of five IPv4 addresses with the subnet mask of 255.255.255.0. Select three of them that belong to the same logical network.
172.16.45.56
172.16.35.45
172.16.45.12
172.16.45.35
173.16.45.18 - answer 172.16.45.56
172.16.45.12
172.16.45.35
How many bits make up an IPv4 address?
32
64
128
48 - answer 32
True or False? Every device on a network needs an IP address to identify itself and communicate on the network.
false
true - answer true
All network devices must have an IP address to communicate on the network. The IP address is used to uniquely identify each device on the network.
When IPv4 is configured for a computer on a network, what does the subnet mask identify?
the part of the IP address that identifies the network
the dynamic subnetwork configuration
the pool of addresses assigned within the network
the device that the computer uses to access another network - answer The IP addressing system is a hierarchical addressing system. An IP address is made up of two parts: the network address and the host address. For IPv4, the subnet mask is used
to identify which portion of an IPv4 address is the network address and which portion is the host address.
What is the purpose of the subnet mask in conjunction with an IP address?
to identify whether the address is public or private
to determine the subnet to which the host belongs
to mask the IP address to outsiders to uniquely identify a host on a network - answer to determine the subnet to which the host belongs
With the IPv4 address, a subnet mask is also necessary. A subnet mask is a special type of IPv4 address that coupled with the IP address determines the subnet of which the device is a member. What are two reasons a network administrator might want to create subnets? (Choose two.)
simplifies network design
easier to implement security policies
improves network performance
reduction in number of switches needed
reduction in number of routers needed - answer easier to implement security policies
improves network performance
Two reasons for creating subnets include reduction of overall network traffic and improvement of network performance. Subnets also allow an administrator to implement
subnet-based security policies. The number of routers or switches is not affected. Subnets do not simplify network design.
A student is helping a friend with a home computer that can no longer access the Internet. Upon investigation, the student discovers that the computer has been assigned
the IP address 169.254.100.88. What could cause a computer to get such an IP address?
unreachable DHCP server
static IP addressing with incomplete information
reduced computer power supply output
interference from surrounding devices - answer unreachable DHCP server
When a PC does not have a static IP address or cannot pick one up from a DHCP server, Windows will automatically assign the PC an IP address using APIPA, that uses the range of addresses 169.254.0.0 to 169.254.255.255.
What are the three ranges of IP addresses that are reserved for internal private use? (Choose three.)
64.100.0.0/14
192.31.7.0/24
172.16.0.0/12
127.16.0.0/12
10.0.0.0/8
192.168.0.0/16 - answer The private IP address blocks that are used inside companies are as follows:
10.0.0.0 /8 (any address that starts with 10 in the first octet)
172.16.0.0 /12 (any address that starts with 172.16 in the first two octets through 172.31.255.255)
