질문 # 42
Which component of a typical Optical Distribution Network requires no electrical power to perform its primary function?
정답：B
설명：
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.
질문 # 43
Which of the following statements correctly distinguishes traffic shaping from traffic policing?
정답：C
설명：
Traffic shaping regulates an outgoing traffic stream by buffering packets that temporarily exceed the configured rate and transmitting them later. This smooths bursts but can introduce additional latency because packets remain in a queue. Traffic policing checks traffic against configured rate limits without normally delaying nonconforming packets. Depending on the policy, packets exceeding the permitted profile can be dropped or marked with a lower priority. Both mechanisms are QoS tools and are independent of whether the physical access medium is fiber, copper, or wireless. They also do not control multicast membership or VLAN assignment. In a fixed-access network, shaping can help produce a smoother egress rate, while policing can enforce subscriber or service bandwidth limits at an ingress boundary.
질문 # 44
What is the primary function of the cladding in an optical fiber?
정답：B
설명：
The cladding surrounds the optical fiber core and has a lower refractive index than the core. This difference causes light to remain confined within the core through total internal reflection, allowing the optical signal to travel along the fiber. The cladding does not generate or amplify light; transmitters and optical amplifiers perform those functions. It also does not divide an optical signal among subscribers, which is the role of a passive optical splitter in an Optical Distribution Network. Outside the cladding, protective coatings and buffers help protect the glass from moisture, bending, and mechanical damage. The core and cladding therefore perform essential optical functions, while the surrounding protective layers primarily provide physical protection.
질문 # 45
Which Corteca component is intended primarily for use by the subscriber during Wi-Fi installation and management?
정답：D
설명：
The Corteca mobile application provides subscriber-facing capabilities that can support self-installation and home Wi-Fi management. Depending on the enabled service, the subscriber can receive installation guidance, view the home network, manage connected devices, and perform supported troubleshooting or configuration tasks. The service provider uses other Corteca platform components for centralized service management, visibility, and operational control. An OLT network termination card provides access-node network connectivity and is not a subscriber application. An IPFIX collector receives traffic-flow records, while a NETCONF candidate datastore holds proposed device configuration before it is committed. Separating subscriber-facing and operator-facing functions allows the provider to offer controlled self-service capabilities without exposing the complete network-management environment or low-level access-device configuration to the end user.
질문 # 46
What is the primary purpose of vectoring in a DSL access network?
정답：B
설명：
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.
