질문 # 29
What is the primary purpose of Zero-Touch Provisioning for a newly installed residential Wi-Fi gateway?
정답：C
설명：
Zero-Touch Provisioning allows a newly connected gateway or Wi-Fi device to discover the appropriate management environment and obtain its required configuration with minimal manual intervention. This reduces installation time, lowers the chance of configuration errors, and makes subscriber self-installation more practical. In a managed home-network solution, the device can be associated with the subscriber, receive service parameters, and become visible to the provider's management platform. Zero-Touch Provisioning does not mean that no configuration exists; it means the configuration is delivered automatically instead of being entered locally by a technician. It also does not prevent management communication or turn an active gateway into a passive device. Successful provisioning still depends on network connectivity, device identity, authorization, and compatible management procedures.
질문 # 30
What is a key characteristic of software disaggregation in an access network?
정답：D
설명：
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.
질문 # 31
A service provider combines two copper pairs to increase the available DSL rate for one subscriber. Which technology is being used?
정답：A
설명：
DSL bonding combines two or more physical copper pairs into a single logical subscriber connection. Traffic is distributed across the available pairs, allowing the aggregate bitrate to increase, provided the individual lines have suitable quality and compatible performance. Bonding can also provide operational benefits where one pair alone cannot deliver the required service rate. It is different from vectoring, which reduces crosstalk among coordinated copper lines by generating compensating signals. Optical splitting divides optical power in a PON and does not combine copper capacity. Multicast replication creates copies of multicast packets for different receiver paths and is unrelated to DSL transmission capacity. Both ends of a bonded DSL connection must support the applicable bonding method and coordinate traffic across the paired lines.
질문 # 32
What is a principal responsibility of the NFV Orchestrator in an NFV environment?
정답：C
설명：
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.
질문 # 33
What is a typical function of the Network Termination card in a Nokia Lightspan access node?
정답：A
설명：
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.
