Net8

Which OSI layer sends segments to be encapsulated in an IPv4 or IPv6 packet?

• Data link layer

• Network layer

  
  

• Transport layer

• Session layer

Which layer is responsible for taking an IP packet and preparing it for transmission over the communications medium?

• Physical layer

• Network layer

• Data link layer

• Transport layer

What is the term for splitting up an IP packet when forwarding it from one medium to another medium with a smaller MTU?

• Encapsulation

• Fragmentation

• Segmentation

• Serialization

Which delivery method does not guarantee that the packet will be delivered fully without errors?

• Connectionless

• Best effort

• Media independent

What are the two most commonly referenced fields in an IPv4 packet header that indicate where the packet is coming from and where it is going? (Choose two.)

• Destination IP address

• Protocol

• Time to Live

• Source IP address

• Differentiated Services (DS)

Which statement is correct about IPv4 packet header fields?

• The source and destination IPv4 addresses remain the same while travelling from source to destination.

• The Time to Live field is used to determine the priority of each packet.

• The Total Length and Header Checksum fields are used to reorder a fragmented packet.

• The Version field identifies the next level protocol.

Which field is used to detect corruption in the IPv4 header?

• Header Checksum

• Time to Live

• Protocol

• Differentiated Services (DS)

Which field includes common values such as ICMP (1), TCP (6), and UDP (17)?

• Header Checksum

• Time to Live

• Protocol

• Differentiated Services (DS)

Which three options are major issues associated with IPv4? (Choose three.)

• IP address depletion

• Increased network complexity and Internet routing table expansion

• Too many IPv4 addresses available

• Lack of end-to-end connectivity

• Global and political boundaries

Which two options are improvements provided by IPv6 as compared to IPv4? (Choose two.)

• Header supports additional fields for complex packets

• Increased the IP address space

• Standardizes the use of NAT

• Supports class-based networks

• Uses a simpler header to provide improved packet handling
