Summary


In this chapter we have examined the structure of IP datagrams, and how IP addresses can be best managed by using the Dynamic Host Configuration Protocol (DHCP). Although Chapter 38 covered some operational aspects of IP, it’s important to understand the structure of IP datagrams for troubleshooting.


Questions

















































1.


What functions does IP not carry out in the stack?



  1. Addressing



  2. Routing



  3. Formatting



  4. Securitization






2.


What protocols does IP not rely upon for its operation?



  1. Address Resolution Protocol (ARP)



  2. Reverse Address Resolution Protocol (RARP)



  3. Simple Mail Transfer Protocol (SMTP)



  4. Internet Control Message Protocol (ICMP)






3.


What command is typically used as the interface to check for errors on the network?



  1. snoop



  2. watch



  3. in.rarpd

4.


What does the Type of Service not specify?



  1. Packets are designated as requiring high speed.



  2. Packets are designated as requiring TCP.



  3. Packets are designated as requiring high reliability.



  4. Packets are designated as requiring maximum bandwidth.






5.


If bits 0–2 of the Type of Service were 000, what would be the message priority?



  1. Normal traffic



  2. Priority traffic



  3. Immediate traffic



  4. Flash traffic






6.


If bits 0–2 of the Type of Service were 001, what would be the message priority?

  2. Priority traffic



  3. Immediate traffic



  4. Flash traffic






7.


If bits 0–2 of the Type of Service were 010, what would be the message priority?



  1. Normal traffic



  2. Priority traffic



  3. Immediate traffic



  4. Flash traffic






8.


If bits 0–2 of the Type of Service were 011, what would be the message priority?



  1. Normal traffic



  2. Priority traffic



  3. Immediate traffic



  4. Flash traffic






9.


What is the maximum total packet length in bytes?



  1. 1500



  2. 16636
