NEW QUESTION # 13
Which experience-assurance technologies does Huawei SD-WAN provide?
Answer: A,B,C,D
Explanation:
Huawei SD-WAN provides all four technologies. Per-flow load balancing distributes separate application flows among multiple links that have the same priority and satisfy the required SLA. Per-packet load balancing can transmit packets from one flow across multiple eligible links, improving aggregate bandwidth utilization for large file transfers, backups, and replication.
Multi-fed and selective receiving duplicates critical traffic across different links. The receiving device selects valid packets, removes duplicates, and preserves packet order. Packet loss or failure on one path therefore does not interrupt the service, enabling zero-millisecond link switchover in applicable deployments.
A-FEC dynamically generates redundant packets and adjusts the redundancy ratio according to measured packet loss. The receiving device reconstructs lost packets, reducing video freezing and voice-quality deterioration. Huawei describes both adaptive FEC and multi-fed selective receiving as WAN-optimization mechanisms for key traffic.
Intelligent traffic steering selects links according to application identity, quality, bandwidth, priority, and load.
Therefore, A, B, C, and D are all correct.
NEW QUESTION # 14
Which of the following WLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer network?
Answer: C
Explanation:
A network serving 15,000 wireless terminals is a large-scale WLAN and should use a standalone WAC solution. A dedicated WAC provides independent controller resources, scalable AP and user management, centralized WLAN policy control, and the ability to deploy controller redundancy without tying wireless- control capacity directly to a specific core-switch service card.
Huawei recommends a standalone WAC when the wireless network scale is large or when the wireless network is deployed independently over an existing wired campus. The WAC is typically connected to the aggregation or core layer in off-path mode, and VRRP hot standby can be used to improve reliability.
Native WAC solutions are valuable for unified wired and wireless management, authentication, forwarding, and policy enforcement. However, for a very large number of wireless terminals, the controller platform must be selected according to user, AP, traffic, and forwarding-capacity specifications. A standalone WAC allows the wireless control plane to be sized and expanded independently.
Option C provides the dedicated WAC together with the required core and aggregation or access infrastructure. Therefore, it is the recommended architecture for 15,000 wireless terminals.
NEW QUESTION # 15
Which of the following can be prevented by using the unauthorized access prevention function of Huawei switches?
Answer: A,B
Explanation:
Huawei switches' unauthorized access prevention function can prevent users from connecting unauthorized hubs and sharing network access through unauthorized Wi-Fi hotspots. An unauthorized hub allows multiple terminals to enter the network through a port intended for a single managed endpoint. This can bypass normal terminal-count limitations, admission controls, and access-policy enforcement.
Unauthorized Wi-Fi hotspot sharing occurs when a user connects an authenticated endpoint to the enterprise network and then enables hotspot or connection-sharing functionality. Other terminals can subsequently access the network through that endpoint without completing the required authentication process. Huawei switches can analyze terminal behavior, MAC-address relationships, packet characteristics, and access patterns to identify and restrict this behavior.
A USB flash drive is a local storage device and does not provide Ethernet network access, so option A is unrelated to switch-based unauthorized network access prevention. An unauthorized router is normally controlled through device identification, NAC, port security, or explicit access policies rather than the specific hub and hotspot-sharing prevention function described by this question.
Huawei intelligent terminal management combines terminal identification, authorization, traffic analysis, and bogus-terminal detection to achieve visualized access and prevent unauthorized connectivity.
NEW QUESTION # 16
What is the function of the PROFINET DCP?
Answer: A
Explanation:
PROFINET DCP, meaning Discovery and Basic Configuration Protocol, is used during device discovery and initial network configuration. It operates at the data-link layer and enables an engineering station or PROFINET IO controller to locate devices on the local Ethernet segment, identify them by MAC address or station name, assign a PROFINET device name, and configure IP parameters such as the IP address, subnet mask, and default gateway.
DCP is therefore not responsible for normal cyclic process-data exchange. Real-time PROFINET communication performs that function after the controller and I/O device have been configured and an application relationship has been established. Alarm exchange and acyclic parameterization are also handled through other PROFINET communication relationships and services.
The distinction matters during commissioning. A new I/O device may initially have no usable IP configuration. DCP allows the controller or engineering tool to discover it at Layer 2 and provision the identity and addressing information required before higher-layer communication can begin. PROFINET documentation identifies DCP as mandatory for assigning IP addresses and configuring station names on the local network.
NEW QUESTION # 17
In hierarchical networking, which of the following devices is used for communication between different areas?
Answer: B
Explanation:
A border device, or more precisely a device at a border site, provides communication between different areas in a hierarchical SD-WAN topology. The hierarchical model divides a large WAN into multiple areas. Each area can independently use a hub-spoke or full-mesh topology, while selected border sites connect the local area to a centralized backbone area.
When a non-border site receives a route originating in another area, the route's next-hop site ID is changed to the border site in its own area. The local border device then forwards traffic toward the border site in the destination area or toward an interconnected hub site. Ordinary edge devices provide connectivity for their own sites but do not automatically perform cross-area transit.
Huawei describes border sites as members of both the level-2 area network and the level-1 backbone network.
These sites collectively implement interconnection between areas. Huawei further explains that inter-area routes point to border sites and recommends two border sites operating in active/standby mode for reliability.
Therefore, the correct answer is B.
