Chapter 8 Quiz

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

• data link layer
• network layer
• transport layer
• session layer

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

• data link layer
• network layer
• transport layer
• session layer

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

• encapsulation
• segmentation
• serialization
• fragmentation

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

• Connectionless
• best effort
• media independent

5. What are the two most commonly referenced fields in the IPv4 packet header?

• destination IP address
• source IP address
• protocol
• Time to Live

6. Which statement is correct about IPv4 packet header fields?

• the source and destination IPv4 addresses remain the same while traveling from source to destination
• the TTL 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

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

• IP address depletion
• Increased network complexity and Internet routing table expansion
• Lack of end-to-end connectivity
• Always on connections
• Global and political boundaries

8. 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

9. Which statement about host forwarding decisions is true?

• A host cannot ping itself
• A remote destination host is on the same local network as the sending host
• Local hosts can reach each other without the need of a router
• Routing is enabled on switched to discover the best path to a destination

10. Which default gateway statement is true?

• A default gateway is required to send packets to other hosts on the local network
• A default gateway address is the IP address of the router on the local network
• A default gateway address is the IP address of a switch on a remote network
• Traffic can only be forwarded outside the local network if there is not default gateway
