質問 # 25
Which characteristic distinguishes G.fast from traditional ADSL technologies?
正解：E
質問 # 26
In intent-based networking, what does an operator primarily specify through an intent?
正解：B
解説：
An intent describes the desired network outcome or target state rather than requiring the operator to manually enter every device-level command. The intent system maps the requested outcome to the configurations and resources needed on the relevant network elements. It can then compare the intended state with the observed operational state and take corrective action when supported. Intent types, profiles, and associated models provide the logic and parameters required for this translation. An intent does not normally specify the electrical construction of hardware or list every packet to be forwarded. Optical measurements may be used as operational inputs, but they are not the general definition of an intent. This abstraction improves consistency, supports automation, and reduces repetitive device-by-device configuration work.
質問 # 27
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.
質問 # 28
In a Lightspan High-Speed Internet service architecture, what is the role of the HSI VPLS on the IHUB?
正解：B
解説：
The HSI VPLS on the integrated hub provides the Layer 2 switching context used to carry High-Speed Internet traffic between HSI forwarders and the network-facing side of the access node. Subscriber traffic arriving through an ONT is associated with an HSI forwarder on the relevant line termination resources. The forwarder connects that traffic to the HSI VPLS, which then switches it toward one or more NNIs leading to the aggregation network. The VPLS does not perform optical-to-analog voice conversion, Wi-Fi radio management, or DSL vectoring. Those functions belong to different service components or technologies. This logical service architecture allows subscriber-facing resources and network-facing interfaces to participate in a controlled Ethernet forwarding domain while supporting the required service separation and policies.
質問 # 29
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：A
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.
