143
Which IP address is a public IP address?

Which IP address is valid for an individual host expressed in dotted decimal notation?
215.233.32.91
Which subnet mask is an example of classless subnetting?
255.255.240.0

2x - 2, where x represents the number of zeroes in the subnet mask
Which formula would you use to calculate the number of new subnets?
2y , where y is the number of bits you add to the subnet mask
How many binary digits are in an IPv4 address?
32
How long is a subnet mask?
32 bits
Which port do HTTP Web servers use?
80
Which statement about subnet masks is true?
All machines on the same network have the same subnet mask.
Which method of sending a packet allows every computer on the LAN to hear the message?
Broadcast
"If the first decimal value of an IP address is between 128 and 191, to what IP class does the network belong?"
Class B
Which statement best describes a Class E address ID?
Class E is considered to be experimental.
Which tool automatically assigns an IP address whenever a computer connects to the network?
DHCP
What is a better known name for dynamic IP addressing?
Dynamic Host Configuration Protocol (DHCP)
What is the universal MAC address for broadcast?
FF-FF-FF-FF-FF-FF
"When a computer gives itself an Automatic Private IP Address (APIPA), it also includes a valid default gateway address."
False
"When you want to be positive that the data moving between two systems gets there in good order, use a connectionless application."
False
The Internet Protocol (IP) works at the Link layer.
False
The Link layer is the most important part of the TCP/IP protocol suite.
False
The part of the IP address that is the same for all computers on a network is called the host ID.
False
User Datagram Protocol (UDP) is a connection-oriented protocol.
False
Using class blocks enables a much more efficient use of IP addresses compared to subnetting.
False
Which protocol uses TCP as its transport layer protocol?
HTTP
Which method of sending a packet allows a single computer to send a packet to a group of interested computers?
Multicast
To what layer of the OSI model does the TCP/IP model's Internet layer roughly correspond?
Network
What is the cornerstone of subnetting?
Subnet mask
Which protocol is connection-oriented?
TCP
What is the de facto protocol suite of the Internet?
TCP/IP
What network protocol do Apple systems use today?
TCP/IP
"When a DHCP client boots up, it automatically sends out a special DHCP Discover message using the broadcast address."
True
"When a technician installs a range of IP addresses, this is called a DHCP scope."
True
Domain Name System (DNS) uses the User Datagram Protocol (UDP).
True
Subnet masks are always 32 binary digits long.
True
Systems that use static IP addressing can never have DHCP problems.
True
The first binary octet of a Class C IP address always begins with 110 (110xxxxx).
True
Transmission Control Protocol (TCP) chops up data into segments.
True
Which protocol do Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) use?
UDP
Which method of sending a packet allows one computer to send a message directly to another user?
