Answer: A

Question 2

Which of the following statements is FALSE regarding the S1-U interface?

A : It is the user plane interface used to connect the E-UTRAN and the EPC core.

B : It relies on the GTP-C path to exchange the 'Echo Request' / 'Echo Response' messages between the eNodeB and the SGW.

C : It may be used to transport user data during the inter-eNodeB handover.

D : It uses the GTP-U protocol.

E : The UDP protocol is used as the transport protocol.

Answer: B

Question 3

Based on the information shown in the exhibit, which of the following is TRUE when the PGW receives a 'Create Session Request' with the 'APN Restriction' set to 'Private1'? Assume everything else is in working condition.

A : The 'Create Session Request' is rejected by the PGW and no bearer is created.

B : The 'Create Session Request' is accepted by the PGW and the bearer is created successfully.

C : The APN cannot be configured with an 'APN Restriction' value of 'Private1'.

D : The 'Create Session Request' cannot have an 'APN Restriction' value of 'Private1'.

E : None of the above answers are correct.

Answer: A

Question 4

Which of the following statements is FALSE regarding the GTP tunnel?

A : The GTP-C tunnel is used to carry the signaling messages.

B : The GTP-U tunnel is used to carry the user data.

C : On the SGW, there is only one GTP-C tunnel over the S5 interface to handle all the bearers to reach the same PGW.

D : A GTP-C tunnel may be associated with multiple GTP-U tunnels over the S5 interface.

E : There is a one-to-one mapping between the S1 bearer and the S1-U GTP-U tunnel.

Answer: C

Question 5

During the establishment of a default bearer, which of the following statements are TRUE regarding the TEID-U assigned by the eNodeB to the S1-U tunnel? (Choose two)

A : The eNodeB includes this TEID-U value in the Create Session Request message sent to the SGW over the S1 interface.

B : The eNodeB includes this TEID-U value in the Attach Request message sent to the MME over the S1-MME interface.

C : The MME includes this TEID-U value in the Create Session Request message sent to the SGW over the S11 interface

D : The MME includes this TEID-U value in the Modify Bearer Request message sent to the SGW over the S11 interface.

E : The eNodeB includes this TEID-U value in the Attach Complete message sent to the MME over the S1-MME interface.

F : The eNodeB includes this TEID-U value in the Modify Bearer Request message sent to the SGW over the S1 interface.
