質問 # 13
Which connection is normally used by a Fixed Wireless Access indoor gateway to reach the service provider's access network?
正解：A
解説：
A Fixed Wireless Access indoor gateway normally uses a 4G or 5G radio connection to reach the service provider's mobile or fixed-wireless access network. Inside the home, the gateway can provide Ethernet and Wi-Fi connectivity to subscriber devices. This separates the wide-area access technology from the in-home distribution technology: cellular radio connects the premises to the operator, while Wi-Fi connects local user devices. A DSLAM is associated with copper-based DSL access, and a passive optical splitter belongs to a PON deployment. A subtending interface connects access nodes rather than a subscriber gateway to a radio network. Depending on the deployment, the FWA gateway may also be remotely provisioned and monitored using an external management platform and standardized CPE-management mechanisms.

What is the primary benefit of enabling IGMP snooping on a Layer 2 device carrying IPTV multicast traffic?
正解：B
解説：
IGMP snooping allows a Layer 2 device to examine IGMP messages exchanged between multicast receivers and the multicast router or querier. From these messages, the device learns which ports lead to hosts that have joined particular multicast groups. It can then forward each multicast stream only to the relevant ports instead of flooding it throughout the broadcast domain. This conserves access bandwidth and prevents subscribers from receiving unnecessary IPTV traffic. IGMP snooping does not replace multicast routing, which remains a Layer 3 function. It also does not prevent hosts from sending membership reports; those reports are essential for learning group membership. The feature is particularly valuable in fixed-access IPTV deployments where several high-bitrate channels may be transported across shared aggregation and subscriber-facing infrastructure.
質問 # 15
Which traffic-delivery method is commonly used for a live IPTV channel watched simultaneously by many subscribers?
正解：C
解説：
Live IPTV channels are commonly distributed using multicast because many subscribers may request the same content at the same time. The network carries a shared stream across common paths and replicates packets only where delivery paths branch toward participating receivers. Subscribers signal membership using protocols such as IGMP. This approach is more bandwidth-efficient than delivering a separate unicast copy from the source to every viewer. Video on Demand is commonly delivered using unicast because each viewer may start, pause, or seek through different content independently. NETCONF notifications carry management events rather than television content. IPTV is packet-based and does not require a separate analog transmission for every copper pair. Effective multicast deployment also depends on correct group control, snooping, routing, QoS, and service-forwarding configuration.
質問 # 16
A YANG model specifies that a configuration leaf can contain an integer from 1 through 4094. What is the principal benefit of this restriction?
正解：A
解説：
YANG can define data types, ranges, patterns, mandatory nodes, default values, and relationships between configuration elements. A range restriction allows management software and network devices to verify that a submitted value falls within the permitted limits. For example, restricting a VLAN-related integer to an appropriate range prevents clearly invalid values from being accepted. This model-driven validation reduces configuration errors and makes automation more predictable. A passive optical splitter has no processing capability and cannot correct invalid configuration. The restriction also does not convert a value into an Ethernet frame or prevent NETCONF access. Instead, NETCONF can carry configuration data structured according to the YANG model, and the server can reject an <edit-config> request when the proposed data violates applicable schema constraints.
質問 # 17
Which Wi-Fi 7 capability allows a compatible device to use more than one frequency-band link as part of the same connection?
