Question 2

For implementing IP mobility with different level of support for residents within

its domain, which protocol is best suited?(*)

a) PMIPv6

b) MIPv6

c) SDN-PMIPv6

Question 3

MIPv6 provides local and global IP mobility, so that it is widely implemented in:

a) Wireless LAN

b) Mobile networks

c) Enterprise wireless networks

d) None of the above

Question 4

Triangular routing is a method for transmitting data packets in communication

networks. Which definition of triangle routing in MIPv6 is correct?

a) Routing of packets to and from MN in foreign link

b) Routing of packets from MN ➔ HA ➔ CN, and vice versa

c) Routing of Binding Update messages from MN to HA

d) None of the above

MN: Mobile Node

HA: Home Agent

CN: Correspondent Node

BU: Binding Update

Question 5

What is/are correct about MIPv6 and PMIPv6:

a) In MIPv6, MN tells the Home Agent about the MN mobility

b) In PMIPv6, MN tells the new MAG to inform the LMA when the MN is connected to

the new MAG

c) In MIPv6, there is no device playing proxy role

MN: Mobile Node

LMA: Local Mobility Anchor

MAG: Mobile Access Gateway

Question 6

PMIPv6 domain is like a home link in MIPv6, what is/are correct among these

statements?

a) Between LMA and MAG, we need to create two tunnels (forward and backward)

b) With tunneling, the source and destination addresses are unchanged in the original

packets between MN and CN

c) When LMA receives a packet from CN toward MN, it only modifies the payload field

d) None of the above

LMA: Local Mobility Anchor

MAG: Mobile Access Gateway

CN: Correspondent Node

MN: Mobile Node

Question 7

Route optimization in PMIPv6 is needed because:

a) Route through LMA has high transmission cost

b) Packet route between LMA and CN has more transmission cost than between

LMA and MN

c) PMIPv6 does not require route optimization

d) None of the above

Question 9

Home Network Prefix (HNP) is sent to MN through Router Advertisement (RA)

message. Who assigns HNP to MN?

a) MAG

b) AAA

c) LMA

d) CN

AAA: Authentication, Authorization, and Accounting

Question 10 During the handover in PMIPv6, if the time for PBU from next MAG (MAG 2) to

reach the LMA is greater than LMA waiting time after DeReg PBU from

previous MAG (MAG 1), then this is regarded as:

a) New MN registration

b) MN handover

c) MN handover relapsed

d) None of the above
