質問 # 17
What is a typical function of the Network Termination card in a Nokia Lightspan access node?
正解：D
解説：
The Network Termination card provides network-facing connectivity for a Lightspan access node. Its faceplate can contain connectors and optical cages used to connect the node to external aggregation, transport, management, synchronization, or other supported interfaces. The card participates in forwarding traffic between subscriber-facing line termination resources and the upstream network. It is an active component and must not be confused with a passive optical splitter in the outside plant. It also does not provide in-home Wi-Fi directly to subscriber devices; that function belongs to a residential gateway or Wi-Fi access point. Analog telephones are normally connected through voice-capable subscriber equipment, such as an ONT with appropriate telephone interfaces, rather than directly to the Lightspan NT card.

What is a key characteristic of software disaggregation in an access network?
正解：D
解説：
Software disaggregation separates access-network software into modules, with each module responsible for a particular functional area. Defined interfaces allow these modules to interact with one another, with higher-level applications, and with abstracted hardware resources. This architecture can improve development flexibility, automation, scalability, and the ability to introduce new functions without replacing an entire vertically integrated platform. It does not mean that all physical constraints disappear or that every module can operate on every device without adaptation. Embedding every function permanently in one appliance describes a tightly integrated architecture rather than disaggregation. APIs are important because they enable communication and programmability between components. Passive optical splitters cannot execute software because they contain no powered processing or control functions.
質問 # 19
Which Lightspan interface type normally connects an access node directly to subscriber-facing equipment?
正解：D
解説：
A User Network Interface is the subscriber-facing interface through which an access node connects to customer-side equipment or services. Depending on the access technology, this relationship can involve ONTs, subscriber ports, or other access termination functions. A Network-to-Network Interface connects the access node toward another network device, typically the Ethernet aggregation or transport network. A subtending interface is used when one access node is connected through another access node, allowing the downstream node's traffic to reach the aggregation network through the upstream node. A loopback interface is a logical interface generally used for management, routing identification, or testing and is not a physical subscriber connection. Correctly distinguishing UNI, NNI, and subtending roles is essential when interpreting an access-node datapath.
質問 # 20
What is a principal responsibility of the NFV Orchestrator in an NFV environment?
正解：B
解説：
The NFV Orchestrator coordinates the lifecycle of network services composed of one or more virtualized network functions and helps coordinate the infrastructure resources required by those services. It can work with Virtual Network Functions Managers and Virtualized Infrastructure Managers during service instantiation, scaling, modification, and termination. The VNFM focuses on the lifecycle of VNF instances, while the VIM manages virtualized compute, storage, and networking resources. The NFV Orchestrator does not terminate GPON optical signals, manage individual home Wi-Fi radio channels as its primary function, or perform physical fiber installation. Its higher-level coordination role helps translate a network-service definition into the deployment and resource actions necessary to create and maintain that service within the virtualized environment.
質問 # 21
In an 802.1X-based subscriber authentication design, which role does the residential gateway normally perform?
正解：B
解説：
The residential gateway normally acts as the 802.1X supplicant. It supplies identity information and participates in the Extensible Authentication Protocol exchange required to obtain network access. The access device or OLT commonly performs the authenticator role, controlling the subscriber-facing port and relaying authentication information between the supplicant and the authentication server. The authentication server, frequently using RADIUS, validates the credentials and returns an authorization result or related policy attributes. The gateway is therefore not itself the RADIUS database or authentication server in this design. A multicast querier performs a separate function by sending IGMP queries to maintain multicast membership information. Before successful authentication, the authenticator generally restricts ordinary subscriber traffic while allowing the authentication exchange required to complete access control.
