ITN 101 Network+ Final Study QUESTIONS
WITH ANSWERS
Which two of the following are DHCP options that a DHCP server
can assign to a DHCP client?
default gateway
DNS server
Dynamic Host Configuration Protocol (DHCP) can be used to
dynamically assign a variety of IP address parameters to a DHCP
client. This eliminates the administrative overhead involved with an
administrator having to manually configure the IP address
information on that client.
Examples of IP addressing parameters (called DHCP options)
include: IP address, subnet mask, default gateway, DNS server, and
WINS server.
A DHCP server would not hand out the IP address of a BOOTP
server, because a BOOTP server is the predecessor to DHCP. A client
would not need to contact both a BOOTP server and a DHCP server.
The Automatic Private IP Addressing (APIPA) feature allows a
networked device to self-assign an IP address from the 169.254.0.0/16
,network. Therefore, if a DHCP client cannot contact their DHCP
server, they can automatically assign themselves an IP address from
the APIPA IP address range.
An IP version 6 (IPv6) address contains how many bits?
128
An IPv6 address has eight fields. Each field contains four
hexadecimal digits. Each hexadecimal digit is made up of four bits.
Therefore, the number of bits in an IPv6 address can be calculated as
follows: 4 bits per digit 4 digits per field 8 fields = 128 bits.
A Byte contains eight bits. An IP version 4 (IPv4) address contains 32
bits. A Media Access Control (MAC) address contains 48 bits.
What is the name of the protocol used with IPv6 to learn the Layer 2
addresses that exist on the same local network?
NDP
Whereas the Address Resolution Protocol (ARP) is used for IPv4,
IPv6 uses the Network Discovery Protocol (NDP) for a similar
,purpose to translate between IPv6 addresses and device Layer 2 MAC
addresses.
You are designing a small office/home office (SOHO) network, and
you wish to have four subnets, while maximizing the number of
hosts per subnet. The network you need to subnet is 192.168.5.0/24.
Which of the following is one of the four subnets you should create?
192.168.5.64/26
Four subnets are supported with two borrowed bits, based on the
formula: number of subnets = 2^s, where s is the number of
borrowed bits (that is, 2^2 = 4). Since a design requirement stated
that the number of hosts per subnet be maximized, you would not
want to use more borrowed bits than necessary. Therefore, you
should choose a 26-bit subnet mask (that is, 255.255.255.192).
The block size is 64 (that is, 256 - 192 = 64). Therefore, the subnets
created by subnetting the 192.168.5.0/24 network with a 26-bit
subnet mask are:
192.168.5.0/26
192.168.5.64/26
192.168.5.128/26
192.168.5.192/26
, What service is typically used to resolve a FQDN?
DNS
Dynamic Host Configuration Protocol (DHCP) allows a network
device to dynamically acquire IP address information from a DHCP
server. This IP address information can contain options such as:
DNS server and WINS server IP addresses.
Address Resolution Protocol (ARP) is a protocol used to resolve the
MAC address for a known IP address.
Domain Name System (DNS) is a protocol used to resolve the IP
address for a known fully-qualified domain name (FQDN).
Windows Internet Name Service (WINS) is a protocol used to resolve
the IP Address for a known NetBIOS computer name.
Given a subnet mask of 255.255.192.0, what is the corresponding
prefix notation?
/18
