This set of Computer Architecture and Organization Multiple Choice Questions & Answers (MCQs) focuses on Computer Architecture And Organization Set 2

Q1 | Which one of the following is not an application layer protocol used in internet?
  • remote procedure call
  • internet relay chat
  • resource reservation protocol
  • local procedure call
Answer: resource reservation protocol
Explaination:
resource reservation protocol is a transport layer protocol used on the internet. it operates over ipv4 and ipv6 and is designed to reserve resources required by the network layer protocols.
Q2 | Which protocol assigns IP address to the client connected in the internet?
  • dhcp
  • ip
  • rpc
  • rsvp
Answer: dhcp
Explaination:
dhcp stands for domain host control protocol. it is responsible to remotely assign ip address to the clients connected to the internet. the server that performs this fuction is called the dhcp server.
Q3 | Which one of the following is not used in media access control?
  • ethernet
  • digital subscriber line
  • fiber distributed data interface
  • packet switching
Answer: packet switching
Explaination:
packet switching is not really related to media access control as it just features delivery of packets of data between devices over a shared network. internet is actually based on packet switching.
Q4 | Which level is the network layer in the OSI model?
  • third level
  • fourth level
  • second level
  • fifth layer
Answer: third level
Explaination:
the network layer is the third level of the open system interconnection model and the layer that provides data routing paths for network communication.
Q5 | Data in network layer is transferred in the form of                          
  • layers
  • packets
  • bytes
  • bits
Answer: packets
Explaination:
data is transferred in the form of packets via logical network paths in an ordered format controlled by the network layer.
Q6 | The network layer contains which hardware device?
  • routers, bridges
  • bridges only
  • bridges and switches
  • routers, bridges and switches
Answer: routers, bridges and switches
Explaination:
this layer contains hardware devices such as routers, bridges, firewalls, and switches, but it actually creates a logical image of the most efficient communication rout and implements it with a physical medium.
Q7 | Network layer protocol exits in                    
  • host
  • switches
  • packets
  • bridges
Answer: host
Explaination:
network layer protocols exits in every host or router. the router examines the header fields of all the ip packets that pass through it.
Q8 | What are the common protocols associated with the network layer?
  • address resolution protocol
  • reverse address resolution protocol
  • internet protocol
  • neighbour discovery protocol
Answer: internet protocol
Explaination:
internet protocol and netware ipx/spx are the most common protocols associated with the network layer.
Q9 | The network layer responds to request from which layer?
  • transport layer
  • data layer
  • application layer
  • session layer
Answer: transport layer
Explaination:
in osi model, we are having 7 layers in which the network layer responds to request from the layer above it called transport layer.
Q10 | The network layer issues request to which layer?
  • transport layer
  • data layer
  • application layer
  • session layer
Answer: data layer
Explaination:
in osi model, we are having 7 layers in which the network layer issues request to the layer below it called data link layer.
Q11 | IP is connectionless.
  • true
  • false
Answer: true
Explaination:
ip is connectionless, is that a data packet can travel from a sender to a receiver without the recipient having to send an acknowledgment connection-oriented protocols exits at other, higher layers of the osi model.
Q12 | Does network layer in TCP/IP and OSI Model are same.
  • true
  • false
Answer: false
Explaination:
the tcp/ip internet layer is in fact only a subset of functionality of the network layer. it describes only one type of network architecture, the internet.
Q13 | What are called routers?
  • the devices that operates at session layer
  • the devices that operates at data layer
  • the devices that operates at application layer
  • the devices that operates at network
Answer: the devices that operates at network
Explaination:
the network interconnection devices that operate at the network layer are usually called routes, which at this point should hopefully come as no surprise to you.
Q14 | ICMP stands for                      
  • internet coordinate message protocol
  • internet control message protocol
  • interconnect control message protocol
  • interconnect coordinate message protocol
Answer: internet control message protocol
Explaination:
the internet protocol is the key network layer protocol that implements the tcp/ip protocol suites. since ip is the protocol that provides the mechanism for delivering datagrams, between devices, it is designed to be relatively basic, and to function with few “bell and whistles”.
Q15 | Packets will be transferred in how many types?
  • 5 types
  • 4 types
  • 2 types
  • 3 types
Answer: 3 types
Explaination:
routing deals with determining how packet will routed (transferred) from source to destination. it can of three types : 1. static
Q16 | DDP stands for                    
  • datagram delivery protocol
  • device delivery protocol
  • datagram device protocol
  • device datagram protocol
Answer: datagram delivery protocol
Explaination:
datagram delivery protocol is a member of the appletalk networking protocol suite. its main responsibility is for socket to socket delivery of datagram over an appletalk network.
Q17 | RIP stands for                  
  • reduced information protocol
  • routing internet protocol
  • routing information protocol
  • reduced internet protocol
Answer: routing information protocol
Explaination:
the routing information protocol is one of the oldest distance vector routing protocols which employ the hop count as a routing metric.
Q18 | The                          model is 7-layer architecture where each layer is having some specific functionality to perform.
  • tcp/ip
  • cloud
  • osi
  • ois
Answer: osi
Explaination:
the osi model is 7-layer architecture where each layer is having some specific functionality to perform. all these layers work in collaboration for transmitting the data from 1 person to another worldwide.
Q19 | The full form of OSI is OSI model is
  • open systems interconnection
  • open software interconnection
  • open systems internet
  • open software internet
Answer: open systems interconnection
Explaination:
the osi model is 7-layer architecture where each layer is having some specific functionality to perform. all these layers work in collaboration for transmitting the data from 1 person to another worldwide.
Q20 | Which of the following is not physical layer vulnerability?
  • physical theft of data & hardware
  • physical damage or destruction of data & hardware
  • unauthorized network access
  • keystroke & other input logging
Answer: unauthorized network access
Explaination:
unauthorized network access is
Q21 | In                                      layer, vulnerabilities are directly associated with physical access to networks and hardware.
  • physical
  • data-link
  • network
  • application
Answer: physical
Explaination:
in the physical layer, vulnerabilities are directly associated with physical access to networks and hardware such as unauthorised network access, damage or destruction of data & hardware and keystroke & other input logging.
Q22 | Loss of power and unauthorized change in the functional unit of hardware comes under problems and issues of the physical layer.
  • true
  • false
Answer: true
Explaination:
loss of power and unauthorized change in the functional unit of hardware comes under problems and issues of the physical layer. other such issues are unauthorised network access, damage or destruction of data & hardware and keystroke & other input logging.
Q23 | Which of the following is not a vulnerability of the data-link layer?
  • mac address spoofing
  • vlan circumvention
  • switches may be forced for flooding traffic to all vlan ports

Answer: overloading of transport-layer mechanisms
Explaination:
mac address spoofing, vlan circumvention and switches may be
Q24 |                          is data-link layer vulnerability where stations are forced to make direct communication with another station by evading logical controls.
  • vlan attack
  • vlan circumvention
  • vlan compromisation method
  • data-link evading
Answer: vlan circumvention
Explaination:
vlan circumvention is data- link layer vulnerability where stations are forced to make direct communication with another station by evading logical controls implemented using subnets and firewalls.
