Which Wi-Fi 7 capability allows a compatible device to use more than one frequency-band link as part of the same connection?
正解：B
質問 # 42
Which component of a typical Optical Distribution Network requires no electrical power to perform its primary function?
正解：C
解説：
A passive optical splitter divides an incoming optical signal into multiple output paths without requiring electrical power. It is a fundamental component of the Optical Distribution Network connecting an OLT to multiple ONTs or ONUs. The splitter does not regenerate, amplify, or actively switch the optical signal. Consequently, splitting introduces optical loss that must be considered when calculating the PON power budget. The OLT and ONT are active devices because they require power to transmit, receive, process, and convert signals. A residential gateway also requires power to provide functions such as routing, firewall enforcement, DHCP, Ethernet switching, and Wi-Fi connectivity. The use of passive splitters reduces the need for powered equipment in the outside plant, which can simplify field maintenance and lower operational costs.

Which Lightspan interface type normally connects an access node directly to subscriber-facing equipment?
正解：A
解説：
A User Network Interface is the subscriber-facing interface through which an access node connects to customer-side equipment or services. Depending on the access technology, this relationship can involve ONTs, subscriber ports, or other access termination functions. A Network-to-Network Interface connects the access node toward another network device, typically the Ethernet aggregation or transport network. A subtending interface is used when one access node is connected through another access node, allowing the downstream node's traffic to reach the aggregation network through the upstream node. A loopback interface is a logical interface generally used for management, routing identification, or testing and is not a physical subscriber connection. Correctly distinguishing UNI, NNI, and subtending roles is essential when interpreting an access-node datapath.
質問 # 44
A QoS policy examines a packet's markings and assigns it to a forwarding class. Which QoS function is being performed?
正解：D
解説：
Classification examines packet information and determines how the packet should be treated by the QoS system. The decision can use fields such as VLAN priority, Differentiated Services Code Point, protocol information, or interface context. After classification, the packet is assigned to an appropriate forwarding class and queue so that scheduling, congestion management, and other policies can provide the intended treatment. Shaping controls an outgoing rate by buffering excess traffic, while policing enforces a traffic profile by dropping or remarking nonconforming packets. Optical amplification increases optical signal power and is unrelated to packet classification. Effective classification is essential when a fixed-access network carries services with different requirements, such as voice, IPTV, management traffic, and best-effort Internet access.
質問 # 45
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.
