IP Protocol Quiz

Craig and Jacob are setting up a network for their new startup. What is the primary function of IP as a Layer 3 connectionless protocol?

• To track and manage the flow of packets

• To deliver packets from host to destination over an interconnected system of networks

• To validate the source IP address

• To encrypt data packets

Jacob and Craig are studying for their networking exam. They come across a question: Which field in the IP header is responsible for error-checking the header?

• Total Length

• Header Checksum

• Protocol

• Time-to-Live

Jacob and Craig are setting up a network and need to know the size of the IP header in bytes. What is the size of the IP header?

• 10 bytes

• 15 bytes

• 20 bytes

• 25 bytes

Jacob and Craig are discussing network protocols. Jacob asks, 'The 'Differentiated Services' field in the IP header specifies (a)   .'

• The total length of the packet
• The type of service and priority of
• The source IP address
• The protocol used

Craig and Jacob are discussing network protocols. Craig asks, 'What does the 'Differentiated Services' (DS) field determine in an IPv4 packet?'

• The length of the IP packet

• The priority of each packet

• The version of the IP packet

• The fragmentation of the packet

Craig and Jacob are discussing network protocols. Craig asks, 'How many bits are used in the 'Differentiated Services' (DS) field?'

• 4 bits

• 6 bits

• 8 bits

• 10 bits

Craig and Jacob are discussing network protocols. Craig asks, 'What are the last two bits of the 'Differentiated Services' (DS) field used for?'

• Differentiated Services Code Point (DSCP)

• Explicit Congestion Notification (ECN)

• Internet Header length

• Total length

Jacob and Craig are discussing network protocols. Jacob asks, 'What is the maximum size of an IP packet as specified by the 'Total length' field?'

• 32,767 bytes

• 65,535 bytes

• 128,000 bytes

• 256,000 bytes

Jacob and Craig are sending a large file over the internet. An IP packet that needs to cross a route that cannot handle its size is (a)  

• It is discarded
• It is reassembled
• It is divided into smaller packets
• It is prioritized

Craig and Jacob are discussing network protocols. Which field in the IPv4 packet header identifies the next-level protocol?

• Time-to-Live (TTL)

• Protocol

• Header checksum

• Options and Padding
