A residential gateway ONT provides routed Internet access to devices in a subscriber's home. Which DHCP role does it normally perform on the home LAN?
正解：B
解説：
A Layer 3 residential gateway normally operates as a DHCP server on the subscriber's home LAN. It assigns private IP addresses and other configuration information, such as the default gateway and DNS server addresses, to connected devices. On its network-facing WAN interface, the gateway may operate as a DHCP client to obtain service parameters from the operator's network. These two DHCP roles must not be confused. The gateway also commonly performs routing, Network Address Translation, firewall enforcement, and local Ethernet or Wi-Fi connectivity. The OLT transports and controls subscriber access traffic but does not normally allocate private LAN addresses directly to individual home devices. This architecture separates the operator-facing connection from the subscriber's private local network and allows multiple home devices to share the broadband service.

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.

Which transport protocol is commonly used to provide a secure connection for NETCONF sessions?
正解：A
解説：
NETCONF is commonly transported over Secure Shell, which provides encryption, integrity protection, and peer authentication for the management session. After establishing the secure transport connection, the client and server exchange NETCONF capabilities and use RPC messages to retrieve or modify device data. IGMP manages IPv4 multicast group membership and does not provide a secure management transport. ARP resolves IPv4 addresses to Layer 2 hardware addresses within a local network. SIP establishes and manages communication sessions such as voice calls. Although NETCONF can conceptually operate over supported secure transports, NETCONF over SSH is the widely recognized deployment model. Secure transport is particularly important because NETCONF can expose operational information and perform configuration changes that materially affect access-network devices and subscriber services.

What is the primary purpose of vectoring in a DSL access network?
正解：C
解説：
DSL vectoring is primarily used to reduce or cancel far-end crosstalk between copper pairs operating within the same cable bundle. Crosstalk can significantly reduce the attainable data rate, particularly with high-frequency technologies such as VDSL2. A vectoring system measures interference among coordinated lines and generates compensating signals that counteract the crosstalk. This can improve connection stability and allow lines to operate closer to their theoretical performance. Vectoring is different from bonding. Bonding combines the capacity of multiple physical copper pairs to increase the aggregate subscriber bitrate. Vectoring also does not divide optical signals because that is the function of a splitter in a passive optical network. Its effectiveness generally depends on coordinating the relevant DSL lines through compatible access equipment.
質問 # 34
Which YANG node type represents multiple scalar values under the same node name without allowing child nodes?
正解：D
解説：
A YANG leaf-list represents a sequence of scalar values of the same defined type. Like a leaf, each value is terminal and cannot contain child nodes. However, unlike a single leaf, a leaf-list can have multiple entries. A YANG list also supports multiple instances, but each list entry can contain child nodes and is normally identified by one or more key leaves. A container groups related child nodes but does not itself represent a repeated collection of scalar values. A choice defines alternative branches in a data model, allowing one set of nodes from the available cases to be selected. Correctly distinguishing these node types is important when interpreting YANG schemas used to configure and monitor access devices through model-driven management interfaces.
