Question 2
Which of the following statements most accurately describes the Diameter protocol?
  1. The Diameter is a peer-to-peer protocol that uses the TCP or SCTP as the transport protocol.
  2. A Diameter peer could act as a Diameter client or a Diameter server to its remote peer.
  3. The Alcatel-Lucent 7750 PGW acts as a Diameter client to the PCRF server via the Gx interface.
  4. The Diameter protocol uses TCP and SCTP port number 3868.
  5. All of the above answers are correct.
  6. Only answers A and B are correct.
Correct answer: E

Correct answer: F
Question 4
Which of the following statements is FALSE regarding the S1-MME interface?
  1. It is the control plane interface between the E-UTRAN and the MME.
  2. It is used to signal the TEIDs for the S1 bearers between the eNodeB and the SGW.
  3. The eNodeB receives the Paging messages over the S1-MME interface.
  4. It is used for the management of the Radio Access Bearers.
  5. It is based on the IP/UDP protocols.
Correct answer: E
Question 5
Which of the following statements is TRUE when the Alcatel-Lucent 7750 MG receives a GTP packet that has a zero TEID?
  1. The ingress IOM forwards the packet directly to the MG-ISM module for further processing.
  2. The ingress IOM drops the packet.
  3. The ingress IOM forwards the packet to the CPM for further processing.
  4. The Alcatel-Lucent 7750 MG forwards the packet to its IP destination by looking into the local IP routing table.
  5. None of the above answers are correct.
Correct answer: C
Question 6
Which of the following statements is FALSE regarding the MG-ISM module on an Alcatel-Lucent 7750 MG?
  1. The MG-ISM module implements the PCC rules for the EPS bearers.
  2. The MG-ISM module can be configured as a SGW/SGSN or a PGW/GGSN.
  3. The MG-ISM module enforces the QoS rules for the EPS bearers.
  4. On an Alcatel-Lucent 7750 MG, two MG-ISM modules can be configured as 1+1 redundant.
  5. The switchover from the active MG-ISM card to the standby MG-ISM card has no impact on other EPC nodes
Correct answer: B

  2. 5 seconds
  3. 6 seconds
  4. 60 seconds
  5. 90 seconds
Correct answer: D
Question 9
On an Alcatel-Lucent 7750 PGW, which of the following is the CLI context where you can specify the IP address and port number of a PCRF server?
  1. Under the Diameter profile context.
  2. Under the Diameter Peer profile context.
  3. Under the Gx interface context.
  4. Under the APN context.
  5. None of the above answers are correct.
Correct answer: B
Question 10
Based on the information shown in the exhibit, which of the following is TRUE when the PGW receives a "Create Session Request" with the "PDNTYPE" set to IPv4? 
  
  1. The PGW tries to allocate an IP address from the subnet "5.5.0.0/16" and assigns it to the UE.
  2. The PGW tries to allocate an IP address from the subnet "3FFE::/48" and assigns it to the UE.
