Fat APs(Autonomous APs) operateindependentlyand donotrequire a centralized wireless controller.

Theyperform all wireless functions, including:

Wireless authentication

Encryption

User access management

Data packet forwarding

Fit APs, on the other hand, depend on a wireless controllerfor centralized management.

Fat APs are best suited for small-to-medium networkswhere centralized control is unnecessary.

Huawei Wi-Fi 6 solutionseliminate signal blind spotsusing their"Unique Dynamic-Zoom Smart Antenna"technology.

(C) True – Dynamic-Zoom Smart Antenna:

Automatically adjustsantenna beamformingbased on terminal location.

Improves signal coverage and reduces interference in complex environments.

Ensuresseamless roamingacross APs withstronger signal stability.

Other options:

(A) DFA (False): DFA optimizesfrequency selectionbut does not eliminate signal blind spots.

(B) AI Roaming Algorithm (False): Enhanceshandover between APs, but does not directly eliminate blind spots.

(D) 6 GHz Band (False): Providesmore spectrum, but coverage depends on the AP's antenna design.

Understanding Overlay Topologies in SD-WAN:

In Huawei's SD-WAN solution, overlay networks are created on top of the physical underlay network. These overlays can be customized based on specific services or applications.

Service Independence:

Different service topologies (e.g., voice, video, data) areindependent of each other, allowing granular control over traffic paths, QoS policies, and security settings.

Conclusion:The statement is TRUE because overlay topologies in Huawei's SD-WAN solution are service-specific and operate independently.

AMAC (Media Access Control) addressis a48-bit unique identifierassigned to network interfaces for communications at the data link layer. It is typically written inhexadecimal format(base-16), which consists of numbers (0-9) and letters (A-F).

Example formats:

Dash-separated:00-21-0A-B9-DC-79

Colon-separated:00:21:0A:B9:DC:79

Continuous:00210AB9DC79

Other options are incorrect:

(A) Decimal – False:MAC addresses are not expressed in decimal format.

(B) Octal – False:Octal (base-8) is not used for MAC addresses.

(D) Binary – False:While MAC addresses are ultimately stored asbinary, they are not presented in this format for human readability.

YANG (Yet Another Next Generation) is adata modeling languageused to define the structure of configuration and state data manipulated by network management protocols.

NETCONF (Network Configuration Protocol)is a network management protocol thatrelies on YANGto provide a standardized way to configure and manage network devices.

YANG defines the structure, while NETCONF provides the transport mechanism to read, modify, and delete configurations.

Other options explained:

SNMP(Simple Network Management Protocol) is used for monitoring but doesnotuse YANG.

CLI(Command-Line Interface) is a manual method for device configuration andnot standardized by YANG.

Telemetryis used for real-time data streaming but isnot dependent on YANG.

Let us analyze each statement in detail:

The CloudEngine S5731-S supports VXLAN and can be used for VXLAN deployment across core and access layers : This statement is false . The CloudEngine S5731-S series does not support VXLAN. VXLAN capabilities are typically found in higher-end switches like the S5731-H or S6730-H series.

The CloudEngine S6730-H24X6C/S6730-H48X6C supports six 100GE ports, which can be auto-negotiated to 40GE ports : This statement is true . The S6730-H series switches support six 100GE ports that can be auto-negotiated to 40GE ports, providing flexibility for high-speed connectivity.

The CloudEngine S5731-H supports native AC and can be used as the core of a small-sized network : This statement is true . The S5731-H series supports native Access Controller (AC) functionality, enabling it to act as the core switch in small-sized networks while managing wireless APs.

The CloudEngine S8706 switch supports four independent service slots and two main control board slots with service ports : This statement is false . The S8706 switch supports six independent service slots and two main control board slots. The description provided in the statement is incorrect.

Thus, the correct answers are B and C .

iMaster NCE (Huawei’s Network Cloud Engine)is anintent-driven network management and control systemdesigned forSDN networks.

It supports both traditional and SDN-capable networks:

SNMPis used to manage and controltraditional (non-SDN) devices.

NETCONF + YANGis used to manageSDN-capable devicesin a structured and automated manner.

CLI is not a preferred method in SDN environmentsas it lacks automation and scalability.

Data Center Networks (DCNs) are evolving towards All-Ethernet architecturesdue to various IT changes.

Key IT changes driving All-Ethernet DCNs include:

A (HDD to SSD transition)→ Increases storage speed, reducing network latency.

B (Centralized to Distributed IT architecture)→ Improves efficiency and scalability.

D (Enterprise Service migration to Cloud)→ Requires a more flexible, high-bandwidth network.

C (PCIe replacement) is incorrect because PCIe is not replaced but rather evolves to newer versions (e.g., PCIe Gen5/Gen6) to support high-speed connections inside servers.

Huawei's iMaster NCE-FabricInsight is an intelligent O&M platform for data center networks that leverages knowledge graph modeling to enhance network management and troubleshooting. Below is an explanation of each option:

"1-3-5" troubleshooting : This refers to a structured approach for fault detection, isolation, and resolution within 1 minute of fault detection, 3 minutes of fault location, and 5 minutes of fault recovery. FabricInsight uses AI-driven analytics to achieve this level of efficiency.

Data plane verification (DPV) : DPV ensures the correctness of the data forwarding path by verifying configurations and detecting anomalies in real time. This helps prevent issues like misconfigurations or routing errors.

Network snapshot comparison : This feature allows administrators to compare network states at different points in time, helping identify changes that may have caused performance degradation or faults.

Network health evaluation : FabricInsight continuously monitors the network and evaluates its health status, providing insights into potential risks and optimization opportunities.

All four options are valid O&M services provided by iMaster NCE-FabricInsight.
