All ONTs receive the same data. An ONU receives its own data and discards the data intended for other ONUs. Options: A. True B. False Answer: A Explanation: Answer: A. True In GPON, the downstream direction works as a broadcast from the Optical Line Terminal (OLT) to all Optical Network Terminals (ONTs/ONUs) on the same passive optical network. Here is what happens: - The OLT sends downstream data to all connected ONTs at once. - Every ONT receives the same downstream optical signal. - Each ONU/ONT checks the data frames and accepts only the data addressed to it. - Data meant for other ONUs is ignored or discarded by the receiving ONU. This is why the statement is correct: downstream GPON uses broadcast transmission, and each ONU receives the broadcast but keeps only its own data. So the correct answer is A. True. Question 2 In a POL, the PON transmits ETH data frames, and Ethernet frames are transmitted upstream by an OLT and downstream by an ONU. Huawei Huawei H19-413_V1.0 PDF https://www.certification-exam.com/ Options: A. True B. False Answer: B Explanation: The correct answer is B. False. In a Passive Optical Network (PON), the direction of transmission is as follows: - Downstream: The Optical Line Terminal (OLT) transmits data toward the Optical Network Units (ONUs). - Upstream: The ONUs transmit data back toward the OLT. The question states that Ethernet frames are transmitted upstream by an OLT and downstream by an ONU. This is the reverse of how a PON works. So the statement is false, which is why option B is correct. Question 3 PON is short for passive optical network. It uses a point-to-point (P2P) access mode. Options: A. True B. False Answer: B Explanation: The correct answer is B. False. PON stands for Passive Optical Network, but it does not use a point-to-point (P2P) access mode. Instead, it uses a point-to-multipoint architecture. In a PON: - A single optical line terminal (OLT) at the service provider side connects to multiple users. - The optical signal is split passively by optical splitters. - This allows one fiber to serve many endpoints without active electronics in the distribution network. By contrast, point-to-point access means each user has a dedicated direct link to the provider, which is not how a PON operates. So the statement is incorrect, making B. False the right answer. Question 4 A PON network consists of the OLTs, ODN, and ONUs. Options: Huawei Huawei H19-413_V1.0 PDF https://www.certification-exam.com/ A. True B. False Answer: A Explanation: The correct answer is A. True. A PON, or Passive Optical Network, is typically made up of three main parts: 1. OLT (Optical Line Terminal) This is the central device located at the service provider’s end. It manages the network and communicates with all connected user devices. 2. ODN (Optical Distribution Network) This is the passive part of the network that carries the optical signal from the OLT to the users. It usually includes fiber cables, splitters, and connectors. It is called passive because it does not require power. 3. ONU (Optical Network Unit) This is the device at the customer’s side that receives the optical signal and converts it for use by the end user. Since a PON network is indeed composed of OLTs, the ODN, and ONUs, the statement is true. Question 5 The NMS of Huawei access products supports rogue ONU detection. Options: A. True B. False Answer: A Explanation: The correct answer is A. True. NMS (Network Management System) for Huawei access products can support rogue ONU detection. A rogue ONU is an unauthorized or improperly registered ONU that may connect to the PON network and interfere with normal service, potentially affecting bandwidth, security, and stability. Huawei access systems include management functions that help detect such devices by monitoring registration behavior, identifying abnormal optical signals, and recognizing ONUs that do not match the expected network configuration. This allows administrators to locate and isolate rogue ONUs more quickly. So the statement is correct: Huawei access product NMS does support rogue ONU detection. Question 6 Type B protection protects OLT PON ports and distribution fibers. Huawei Huawei H19-413_V1.0 PDF https://www.certification-exam.com/ Options: A. True B. False Answer: B Explanation: The correct answer is B. False. Type B protection in a PON (Passive Optical Network) typically protects the optical line terminal (OLT) side by providing redundancy for the PON port or line card, but it does not protect both the OLT PON ports and the distribution fibers together in the way described. In general: - Type B protection usually means there is a standby or redundant OLT PON port, so if one port fails, another can take over. - The distribution fiber, which runs from the OLT to the splitter or optical distribution network, is not fully protected in Type B protection. Since the statement says Type B protection protects both OLT PON ports and distribution fibers, it is inaccurate. That is why the correct answer is False. Question 7 Which of the following rates are correct about 50G-PON? Options: A. 25 Gbit/s downstream and 50 Gbit/s upstream B. 25 Gbit/s downstream and 25 Gbit/s upstream C. 50 Gbit/s downstream and 50 Gbit/s upstream D. 50 Gbit/s downstream and 25 Gbit/s upstream Answer: C, D Explanation: 50G-PON refers to the next-generation passive optical network standard designed to support very high data rates over fiber access networks. The key point is that 50G-PON is defined to operate at 50 Gbit/s in the downstream direction, and it can also support 50 Gbit/s in the upstream direction. Depending on the specific deployment profile or interpretation of the standard, both symmetric and asymmetric rate options may be considered valid, but the rates associated with 50G-PON include: - 50 Gbit/s downstream and 50 Gbit/s upstream - 50 Gbit/s downstream and 25 Gbit/s upstream So the correct choices are C and D. Why the other options are incorrect: - A: 25 Gbit/s downstream and 50 Gbit/s upstream is not a standard 50G-PON rate pairing. Huawei Huawei H19-413_V1.0 PDF https://www.certification-exam.com/ - B: 25 Gbit/s downstream and 25 Gbit/s upstream describes a lower-speed symmetric PON, not 50G-PON. In summary, 50G-PON is associated with 50 Gbit/s downstream, and it may be implemented with either 50 Gbit/s or 25 Gbit/s upstream, making C and D correct. Question 8 The FTTM solution can be used in campus production scenarios such as manufacturing, coal mines, oil and gas, and ports. Options: A. True B. False Answer: A Explanation: The correct answer is A. True. FTTM stands for Fiber to the Machine, a network solution designed to provide reliable, high-speed, and low-latency connectivity in industrial and campus environments. It is commonly used in production scenarios where stable communication is critical for operations, monitoring, and automation. The listed environments, such as manufacturing, coal mines, oil and gas, and ports, are all typical campus production scenarios. These industries often require robust networking solutions to support industrial equipment, real-time data transmission, video surveillance, and control systems. FTTM is suitable for these settings because it can help ensure secure and efficient connectivity across complex operational areas. Therefore, the statement is true. Question 9 In a passive optical LAN (POL), upstream data is transmitted in time division multiplexing (TDM) mode. The OLT allocates independent bandwidth and timeslot to each ONU. Options: A. True B. False Answer: A Explanation: Answer: A. True In a passive optical LAN (POL), the upstream direction from the ONUs (Optical Network Units) back to the OLT (Optical Line Terminal) is typically shared among multiple users. To prevent collisions, the upstream traffic is sent using time division multiplexing (TDM), where each ONU transmits only during its assigned Huawei Huawei H19-413_V1.0 PDF https://www.certification-exam.com/ time slot. The OLT is responsible for managing this access. It schedules the upstream transmission by assigning: - Independent bandwidth to each ONU - Specific time slots for each ONU to transmit This coordination ensures efficient and orderly use of the shared optical fiber, allowing multiple ONUs to communicate upstream without interfering with one another. Why the statement is true: - Upstream data in POL uses TDM - The OLT allocates bandwidth dynamically or statically - Each ONU gets its own transmission timeslot - This prevents upstream contention on the shared medium Therefore, the statement is correct, and the answer is A. Question 10 An optical splitter evenly allocates bandwidth based on the split ratio. Options: A. True B. False Answer: B Explanation: The correct answer is B. False. An optical splitter does not allocate bandwidth based on the split ratio. Instead, it divides optical power among multiple output paths. The split ratio refers to how the optical signal’s power is distributed, such as 1:2, 1:4, or 1:8. Bandwidth is not evenly allocated by an optical splitter in the way the question suggests. In fiber-optic networks, splitters passively split the light signal, which means each output receives a portion of the signal power, not a dedicated amount of bandwidth. So the statement is false because: - Split ratio describes power division, not bandwidth allocation. - Optical splitters are passive devices. - They do not manage or assign bandwidth to users or devices. Therefore, the correct answer is B. False. Would you like to see more?
