質問 # 16
Within the ETSI NFV management and orchestration architecture, which functional block manages virtualized compute, storage, and networking resources?
正解：A
解説：
The Virtualized Infrastructure Manager manages the compute, storage, and networking resources that form the NFV Infrastructure. Its responsibilities can include allocating resources to virtual workloads, tracking available capacity, and controlling the virtualized environment. The Virtual Network Functions Manager has a different role: it manages the lifecycle of VNF instances, including operations such as instantiation, scaling, updating, and termination. Higher-level NFV orchestration coordinates network services and resources across the NFV environment. A traditional Network Management System can perform fault, configuration, accounting, performance, and security management, but it is not the NFV functional block specifically defined to control virtual infrastructure resources. An ONT is subscriber-premises access equipment and is unrelated to NFV infrastructure resource management.

質問 # 17
A network controller must modify configuration data stored on a NETCONF-capable access device. Which NETCONF operation is designed for this purpose?
正解：C
解説：
The NETCONF <edit-config> operation is used to create, change, merge, replace, or delete configuration data in a target configuration datastore. The target can be a datastore such as running or candidate, depending on the capabilities supported by the network device. By comparison, <get-config> retrieves configuration data and does not modify it. <close-session> requests an orderly termination of the current NETCONF session, while <kill-session> forces the termination of another session identified by its session ID. NETCONF operations are carried within RPC messages and commonly transported over a secure protocol such as SSH. YANG models define the structure, types, constraints, and relationships of the configuration and operational data manipulated through NETCONF.
質問 # 18
In a voice service delivered through an ONT, which component commonly provides signaling toward the operator's SIP infrastructure?
正解：B
解説：
A voice-capable ONT commonly contains a SIP agent that handles signaling toward the operator's SIP registrar and proxy infrastructure. An analog telephone can connect to a telephone interface on the ONT, which converts between the analog user interface and the packet-based voice service. Within the access node, voice traffic can be carried through a voice forwarder and an appropriate VPLS toward the aggregation network. A passive optical splitter merely divides optical power and cannot originate or terminate SIP signaling. A Wi-Fi mesh satellite extends wireless coverage, while IGMP snooping manages Layer 2 forwarding for multicast groups. SIP signaling establishes and manages communication sessions, whereas the actual media stream is commonly carried separately using a real-time transport protocol once the call has been established.
質問 # 19
In a GPON system using Dynamic Bandwidth Allocation, which device determines when an ONT may transmit upstream traffic?
正解：A
解説：
The OLT controls upstream access to the shared GPON medium. Multiple ONTs use the same upstream wavelength, so uncoordinated transmissions could overlap and cause collisions. Through Dynamic Bandwidth Allocation, the OLT evaluates bandwidth requirements and assigns upstream transmission grants to the ONTs. These grants specify when an ONT can transmit and how much upstream capacity it may use. Traffic containers, or T-CONTs, help represent different upstream traffic and service requirements. The passive splitter cannot schedule traffic because it has no processing capability. The residential gateway handles subscriber-side functions, while an aggregation switch forwards Ethernet traffic beyond the access network. Centralized upstream scheduling enables efficient bandwidth sharing and helps the operator support different service priorities and performance commitments across subscribers.
質問 # 20
What is a principal responsibility of the NFV Orchestrator in an NFV environment?
正解：C
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.
