Pass the Huawei HCIP Transmission H31-341_V2.5 Questions and answers with CertsForce

The Delay Measurement (DM) function in MPLS-TP OAM can be used to measure the delay and jitter of service packets accurately. This function is essential for maintaining quality of service (QoS) in transport networks by monitoring timing and synchronization characteristics. Accurate delay and jitter measurement helps in diagnosing performance issues and ensuring service-level agreements are met. HCIP-Transmission emphasizes the use of DM in OAM for real-time monitoring and fault localization in MPLS-TP environments.

In Link Aggregation Group (LAG) settings, port priority determines which ports carry traffic preferentially. (A) If a primary port is configured to preferentially carry services, it must have a higher priority than other ports to ensure it is selected first. Port priority is numerically represented, and (D) a lower value of “port priority” means higher priority, which can be counterintuitive but is standard in networking. For manual aggregation groups that don’t run LACP, priority settings typically do not apply. This priority mechanism helps optimize link utilization and failover in aggregated links, as detailed in HCIP-Transmission documentation on Ethernet and service aggregation.

Abnormal optical power can be caused by external factors such as (A) bent optical cables causing increased attenuation or microbends, (B) contaminated connectors reducing transmission efficiency due to dirt or dust, and (C) old optical fibers suffering from aging and degradation that increase loss. (D) Crossed pairs on the ODF (Optical Distribution Frame) is more related to wiring errors but may not directly cause optical power anomalies. HCIP-Transmission stresses proper handling and maintenance of fibers and connectors to maintain optimal optical power levels and network reliability.

Among the differences between MPLS-TP OAM and MPLS OAM, the interval for sending OAM packets is not changed by canceling 3.3 ms and 10 ms values (D). This means these intervals remain in place or are not the key differentiators. The other options (A, B, C) correctly describe differences such as packet formats, label alarms (AIS, RD1, UNEXPMEG), and added functions (CC, AIS, LB, LT) unique to MPLS-TP OAM. HCIP-Transmission materials clarify these differences to aid in understanding the enhanced OAM capabilities for transport profile MPLS networks.

For an OA system, the lower threshold of receive optical power of a line board with an APD receiver or the WDM side of an OTU board is the optical module’s receiver sensitivity plus 3 dB, not 5 dB. The 5 dB margin applies mainly to PIN receivers. This distinction is critical because APDs have higher sensitivity and thus require a smaller margin to avoid false alarms or unnecessary protection switching. HCIP-Transmission clearly differentiates these thresholds to ensure proper optical power management and alarm settings in the network.

The term “Directioned” in WDM systems means that the wavelength carrying local services can be transmitted in a specific direction. This contrasts with directionless systems, where wavelengths can propagate in either direction without restriction. Directioned capability allows more controlled and secure wavelength routing, especially in ring or mesh networks where traffic flows need clear paths. Colorless refers to wavelength independence (a device can handle any wavelength), while colored means the device or port is assigned to a fixed wavelength. Thus, directioned accurately describes the wavelength propagation direction property as per HCIP-Transmission explanations on optical network design and wavelength routing.

Data dumping on Network Management Systems (NMS) can occur in several types: (A) Periodic dumping, where data is saved at set intervals for monitoring and analysis; (C) Overflow dumping, triggered when buffer capacity is exceeded; and (D) Manual dumping, initiated by user commands. (B) Automatic dumping is not a standard term here or is often encompassed within periodic or overflow dumping mechanisms. HCIP-Transmission references these types as part of NMS data handling and fault diagnosis strategies, enabling efficient network performance management and troubleshooting.
