質問 # 42
An optical link experiences unexpectedly high signal loss immediately after a fiber cable is routed around a very tight corner. What is the most likely cause?
正解：C
解説：
Macrobending occurs when an optical fiber is bent with a radius smaller than its supported minimum bend radius. The excessive bend can cause part of the optical signal to escape from the core, increasing attenuation and reducing the received optical power. This problem can appear after poor cable installation, improper storage, or routing the cable sharply around structural objects. Chromatic dispersion causes different wavelengths or spectral components of an optical pulse to travel at slightly different speeds, but it is not normally triggered by one tight physical corner. DSL crosstalk applies to copper pairs, while Dynamic Bandwidth Allocation controls upstream transmission opportunities in a PON. Correcting the cable routing and respecting the specified bend radius can remove or reduce the loss.

A QoS policy examines a packet's markings and assigns it to a forwarding class. Which QoS function is being performed?
正解：B
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 # 44
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：D
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.

What is the primary benefit of enabling IGMP snooping on a Layer 2 device carrying IPTV multicast traffic?
正解：C
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 # 46
A subscriber installs several coordinated Wi-Fi access points to provide consistent coverage throughout a large home. What type of solution is this?
正解：D
解説：
A Wi-Fi mesh system uses multiple coordinated Wi-Fi nodes or access points to extend wireless coverage across a home or other large area. The nodes operate as part of one managed system and can steer clients or select paths to improve coverage and user experience. This differs from a single Wi-Fi router, which combines routing, switching, and wireless access functions in one device but may not adequately cover a large property. A passive optical network delivers fiber access and does not describe the in-home wireless topology. DSL bonding combines copper pairs, while a virtual network function is a software implementation of a network function running on virtualized infrastructure. Placement, backhaul quality, interference, and radio-resource management all affect mesh performance.
