Use the questions here to review what you learned in the chapter. The correct answers are found in Appendix A, “Answers to Review Questions.”

  1. Which organization is driving the framework for NFV

    1. European Telecommunications Standards Institute (ETSI)

    2. Internet Engineering Task Force (IETF)

    3. International Telecommunication Union (ITU)

    4. Open Network Consortium (ONC)

  2. What are the three major blocks of the NFV architecture?

    1. VIM, NFVO, and VNFM

    2. ETSI, MANO, and VNF

    3. NF, NFVI, and MANO

    4. OSS, BSS, and VNF

  3. VNFM is responsible for which of the following?

    1. managing the infrastructure hardware and controlling its allocation to the VNFs

    2. managing the lifecycle of the VNF (instantiation, scaling up or down, termination) as well as FCAPS management of the VNF

    3. deploying the end-to-end service in the NFV architecture

    4. gathering the FCAPS information of the physical hardware from VIM and passing them to NFVO so that the resources can be appropriately managed by the upper layers for the ETSI framework

  4. Which management functional block facilitates running multiple virtual machines/VNFs on the same hardware?

    1. Virtualized Network Function Manager (VNFM)

    2. Virtualization Infrastructure Manager (VIM)

    3. Element Manager (EM)

    4. Network functions virtualization Orchestrator (NFVO)

  5. Communication between different functional blocks such as VIM to VNFM, VNFM to NFVO in the ETSI architecture is called?

    1. communication end points

    2. open network interconnects

    3. FCAPS data points

    4. reference points

  6. List three benefits of NFV compared to traditional network devices:

    1. deployment agility

    2. hardware-centric

    3. elasticity

    4. vendor independence

  7. The abbreviation “COTS” stands for

    1. custom option to service

    2. commodity-oriented technical solution

    3. commercial off the shelf

    4. commercially offered technical solution
