질문 # 13
Which of the following statements correctly distinguishes traffic shaping from traffic policing?
정답：A
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 # 14
Which Corteca component is intended primarily for use by the subscriber during Wi-Fi installation and management?
정답：C
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 # 15
A network controller must modify configuration data stored on a NETCONF-capable access device. Which NETCONF operation is designed for this purpose?
정답：A
설명：
The NETCONF <edit-config> operation is used to create, change, merge, replace, or delete configuration data in a target configuration datastore. The target can be a datastore such as running or candidate, depending on the capabilities supported by the network device. By comparison, <get-config> retrieves configuration data and does not modify it. <close-session> requests an orderly termination of the current NETCONF session, while <kill-session> forces the termination of another session identified by its session ID. NETCONF operations are carried within RPC messages and commonly transported over a secure protocol such as SSH. YANG models define the structure, types, constraints, and relationships of the configuration and operational data manipulated through NETCONF.
질문 # 16
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.
질문 # 17
Which connection is normally used by a Fixed Wireless Access indoor gateway to reach the service provider's access network?
정답：C
설명：
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.
