Review Questions


1:

List the major entities in a Mobile IP deployment.

2:

Mobile IP provides which of the following features? (Select two.)

  1. A dynamic security association between the Mobile Node and Home Agent that changes as the Mobile Node roams across different subnets

  2. Seamless roaming across IP subnets

  3. Redirection routing to the Mobile Node based on the distance to the Mobile Node's new location

  4. Mobility transparent to Correspondent Nodes

  5. Host-specific routing to the Mobile Node

3:

In Mobile IP, when a Mobile Node moves to another domain, how do the Correspondent Nodes (CNs) now communicate with the Mobile Node?

  1. The Mobile Node informs the Correspondent Node of its movement, and thus a dynamic tunnel is created between the Correspondent Node and the Mobile Node's Care-of Address. The Correspondent Node sends packets for the Mobile Node through the tunnel.

  2. The Correspondent Nodes communicate as normal with the Mobile Node, sending packets to the Mobile Node's home IP address. The Home Agent intercepts the packets and forwards them to the Mobile Node through a dynamic tunnel established between the Home Agent and Care-of-Address.

  3. The Correspondent Nodes sends packets to the home network and requests the Home Agent to tunnel the packets to the Mobile Node through the Mobile Node's Care-of Address.

  4. The Correspondent Node suspends communication with the Mobile Node until the Mobile Node returns home.

4:

Which two features of a mobility protocol are facilitated by agent advertisements in Mobile IP?

  1. Location discovery

  2. Move detection

  3. Update signaling

  4. Path (re)establishment

5:

Which of the following is not used for move detection?

  1. The router address and prefix length extension portion of the agent advertisement

  2. The Care-of Address portion of the agent advertisement

  3. Link-state information

  4. RRQ message

6:

Mobile IP handover occurs at Layer 2.

  1. True

  2. False

7:

Name three different types of Mobile IP handover policy algorithms. Briefly describe each one.

8:

How does a Mobile Node know whether it is on its Home Network or a Foreign Network?

  1. By comparing the lifetime granted in its current Mobile IP registration against that advertised in Mobile IP agent advertisements

  2. By comparing the FA address configured on the Mobile Node against that advertised in the Mobile IP agent advertisements

  3. By comparing its CoA against the Home Agent address advertised in Mobile IP agent advertisements

  4. By comparing its Home Address and network prefix against those advertised in Mobile IP agent advertisements

9:

A Mobile Node finds itself away from home on a network with a FA. Describe the Mobile IP registration process, starting with how the Mobile Node learns that it is not home.

10:

What types of CoAes can a Mobile Node use on a Foreign Network?

11:

Which of the following are advantages of a Mobile Node using a FA CoA? (Select two.)

  1. Many Mobile Nodes can roam off of the same CoA, which saves address space in IPv4.

  2. The Mobile Node can retain the same FA CoA as it moves across different foreign domains.

  3. The Mobile Node can be preconfigured with the FA CoA.

  4. The same tunnel between the Home Agent and FA can support numerous Mobile Nodes.

  5. The Mobile Node does not need to reregister with its Home Agent when it moves to a different foreign domain.

12:

Which of the following indicate situations when the Mobile Node would use a Colocated CoA? (Select two.)

  1. If the Mobile Node is statically configured with a Colocated CoA

  2. If the Mobile Node doesn't hear an agent advertisement from a FA on the foreign domain

  3. If the Mobile Node doesn't hear an agent advertisement from its Home Agent on the foreign domain

  4. If the Mobile Node cannot detunnel its own packets

  5. If the FA is not providing services that the Mobile Node would like

13:

How does a Mobile Node signify to the Home Agent that it would like a dynamic Home Address to be assigned?

14:

Describe the steps that a FA follows during the registration process.

15:

Describe the steps that the Home Agent follows upon receiving a RRQ from a Mobile Node.

16:

What is triangle routing?

17:

What does a Mobile Node do upon returning home?
