This updated guide examines Computer Network Test with Answer P11 and organizes the essential facts, background, and practical takeaways in clear American English.

• Question 1: The commonly used protocol on the Internet is:
  • Ethernet
  • TCP / IP
  • OSI
  • IEEE
• Question 2: Hub is the operating device at the top of OSI model:
  • Data Link floor
  • Network floor
  • Transport floor
  • Physical floor
• Question 3: A 100Mbps Hub has 12 ports, the speed of each port will be:
  • Maximum 100Mbps when 12 computers are plugged into the Hub
  • Minimum of 100Mbps when only one computer plugs into the Hub
  • Maximum 100Mbps when only one computer plugs into the Hub
  • Minimum of 8.3Mbps when 12 computers are plugged into the Hub
• Question 4: What kind of device does the NIC operate in the OSI model:
  • Grade 4
  • Grade 3
  • Grade 2
  • Grade 1
• Question 5: Switch is the device that operates in any layer of the OSI model:
  • Grade 4
  • Grade 3
  • Grade 2
  • Grade 1
• Question 6: Topologies commonly used in LANs:
  • Ethernetbus
  • Token Ring
  • Token bus
  • Bus
• Question 7: To connect two computers directly, we can use:
  • Rollover Cable
  • Cross-Cable
  • Straight Cable
  • None of the above
  Refer to: How to connect 2 laptops by network cable
• Question 8: How many layers of OSI classification model:
  • 2
  • 3
  • 5
  • 7
  Further reference: Check knowledge of OSI model
• Question 9: The unit of protocol data in the OSI model is called:
  • Frame
  • Packet
  • PDU
  • CSU
  PDU stands for Protocol Data Unit.
• Question 10: The order of packing data when passing through OSI model:
  • Data, Segment, Packet, Frame, Bit
  • Data, Segment, Frame, Packet, Bit
  • Data, Packet, Segment, Bit, Frame
  • Data, Packet, Segment, Frame, Bit
• Question 11: If you take a class B address to divide Subnet with Netmask is 255.255.240.0, how many subnets can be used (useable subnets)? 240 = 11110000/2
  • 2
  • 6
  • 16 or 14
  • 30
• Question 12: Which network device is used to connect networks and control broadcast?
  • Ethernet switch
  • Bridge
  • Hub
  • Router
• Question 13: Which address is the broadcast address of class 2?
  • 111.111.111.111
  • AAAA. AAAA. AAAA
  • FFFF. FFFF. FFFF
  • 255.255.255.255
  FFFF. FFFF. FFFF (11111111. 11111111. 11111111. 11111111. 11111111. 11111111/2)
• Question 14: Which address is used by SWITCH when deciding which port to send data to?
  • Destination MAC address
  • Source MAC address
  • Subnetwork address
  • Network address
• Ques 15: A subnet of Class C borrows 5 bits to divide Subnet, then SubnetMask will be:
  • 55.255.255.1
  • 255.255.224.0
  • 255.255.255.128
  • 255.255.255.248
  255.255.255.248 (11111000/2 = 248)
• Question 16: Which network interface card (NIC) is in the OSI model?
  • Layer 4

• Question 17: How many IP addresses are needed for 4 PCs connected to each other via HUB?
  • first
  • 2
  • 3
  • 4
• Question 18: What layer does Routers work in in the OSI model?
  • Layer 1
  • Layer 2
  • Layer 3
  • Layer 4
• Question 19: What is the maximum permitted length when using UTP network cables?
  • ten
  • 100
  • 200
  • 600
• Question 20: How many collision domains are there in the network including 88 computers, 10 HUBs and 2 REPEATERs?
  • 0
  • first
  • twelfth
  • 15
