(VERSION A AND B) COMPLETE 500
QUESTIONS WITH DETAILED
VERIFIED ANSWERS (100% CORRECT
ANSWERS) /ALREADY GRADED A+
VERSION A
which OSI model transport layer protocol uses
connectionless protocol to sends simple broadcast
messages
A TCP
B UDP
C IP
D PPTP - ....ANSWER...UDP
,what is the address size of IPv6 addresses
32 bits
64 bits
128 bits
256 bits - ....ANSWER...128 bits
private IP range - ....ANSWER...10.0.0.0 to
10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
NDP (Neighbor Discovery Protocol) -
....ANSWER...similar to ARP(address resolution
protocol) for IPv4
TTL (Time to live) - ....ANSWER...one of the IP header
values
Which application architecture is the only
architecture in which all processing functions occur
on the client?
,Client-based
Client/server
Cloud computing
P2P - ....ANSWER...P2P
_________ is a rapidly emerging use case for
untrusted P2P applications. - ....ANSWER...blockchain
technology
N-tier - ....ANSWER...The new architecture was so
successful, many organizations began adding
multiple appServers, leading to the more common
term, N-tier architecture.
This N-tier architecture used to exist only in an in-
house data center. Today, cloud computing makes it
possible for organizations of any size to lease data
center infrastructure and implement an N- tier
architecture.
Compare and contrast the TCP/IP model with the OSI
model. How are they different? How are they similar?
- ....ANSWER...Difference: The number of layers and
, naming conventions. Similarity: Both provide
conceptual frameworks for understanding network
communication.
What are the major differences between circuit-
switched, packet-switched, and IP-based
communications? - ....ANSWER...Circuit-switched -
old POTS lines, support real-time communications
without much delay, full integrity, no collision,
transmit full message. Expensive due to circuit per
conversation until terminated and network carriers
need to charge for that amount even if the line isnt
used
How does IP-based communication work in today's
networks? - ....ANSWER...Devices communicate
using IP addresses, and data is transmitted in
packets over networks, primarily using the TCP/IP
protocol suite.
What is the difference between routing and
switching in network technology? -
....ANSWER...Routing: Involves directing data
between different networks. (over IP addresses)
