ITS 170 Final Exam
IPv4 address is limited resource and depleting. To overcome this problem, shot-term solution was introduced. What are they?
DHCP Non routable Address NAT/NAPT
ISDN stands for
Integrated services digital network
Subnetting offers all of the following benefits except
It helps DNS operations
One of the popular interior routing protocols is
OSPF
OSPF
Open Shortest Path First
The basic unit of Internet routing is
a router
In dynamic allocation, IP addresses are assigned by DHCP
automatically and for a short period ,based on a first come, first serve basis from a pool of addresses
DHCP
enables IP address reuse
The pull model of communication used on the web means that
end user must choose to pull down content on web pages
Subnetting is most useful for
network administatiors
You have created a new application protocol for online games. To use this protocol, users will need to install
only the new application protocol
Wide area are defined by their ability to
provide data communication services to a large number of users
Compared to routers, switches typically cannot
select the correct path from multiple available paths
Routing is the process of
selecting information paths from the source network to the destination network
The number of subnets in the organization is best determined by
the structure of the organization
A unique feature of the application layer compared to the other layers of the TCP/IP stack is that
there is a separate protocol for each application
DNS stands for
Domain Name System
Dense Wave Division Multiplexing(DWDM) is one of multiplexing technique which uses time slot
False- it uses dense wave
MPLS stands for multi-process label switching
False-Multi-protocol label switching
When a client wishes to translate the hostname www.example.com, it sends a translation request to
The DNS server
A URL is
a character string describing the location and access method of a networked resource
ATM specifies data rates in the range of
1.544Mbps - 622.08 Mbps
All of the following are RFC 1918(Non-Routable) address blocks except
118.7.8.0/24
When the subnet mask 255.255.0.0 is applied to the IP address 172.16.151.45, the result is
172.16.0.0
An organization has 64 subnets. The subnet part of the IP addresses in the organization must have a least
6 bits
WAN links are relatively expensive and it is suggested to use those link more efficiently. Link utilization can be improved by.
Aggregating the traffics
Since WAN support large number of users, multiplexing technologies such as TDM and FDM were used to overcome the limitation of point to point connection. What does FDM and TDM stand for
FDM- Frequency Division Multiplexing TDM- Time Division Multiplexing
Class A IP address has 8 host bits
False 8 Network 24 Host
The application layer is responsible for segmenting user data?
False-
Non-routable addresses are useful because they enable automatic IP address assignment
False- DHCP
Address Resolution Protocol(ARP) is used to acquire IP address from DHCP server
False- It acquires MAC address
Broadcast is the easiest data transfer method and mainly used in WAN technology
False- It uses LAN
SMTP stands for
Simple Mail Transfer Protocol
The limitations of point to point technologies include all of the following except
The split the physical medium into multiple time slots
ATM stands for Asynchronous Transfer Mode
True
An autonomous system is a collection of routers under one administrative entity
True
DHCP stands for Dynamic Host Configuration Protocols
True
HTTP stands for HyperText Transfer Protocol
True
Routing protocols are the mechanisms used by routers on the internet to maintain routing tables
True
Simple Main Tranfer Protocol(SMTP) is one of the application protocols to transfer email between mail servers?
True
Subnetting is a way of breaking down large blocks of IP addresses into smaller address blocks
True
The subnet mask of class B IP address is 255.255.0.0
True
