Huawei'sAdaptive Security Engine (ASE)is a key feature in its security products, such as firewalls. ASE dynamically allocates CPU resources to different service modules (e.g., firewall, intrusion prevention, antivirus) based on real-time traffic demands. This ensures optimal resource utilization and performance.Additionally, ASE supportscomponent-based function delivery, allowing administrators to enable or disable specific security features as needed. This flexibility enhances scalability and reduces unnecessary resource consumption.

The statement accurately describes the functionality of ASE, making itTRUE.

Huawei'sCloudEngine series switchesare designed to meet the evolving demands of modern data center networks (DCNs). For customers requiring25G Top-of-Rack (TOR) switches, theCE6881is the ideal choice.Key details about the models mentioned:

CE6820:A lower-end switch that does not support 25G ports.

CE6870:Primarily supports 10G and 40G ports, not 25G.

CE6881:Specifically designed for 25G access and 100G uplinks, making it suitable for AI-era DCNs.

CE6863E:Focuses on high-density 100G/400G switching, not 25G TOR requirements.

TheCE6881aligns perfectly with the need for 25G TOR switches, enabling higher bandwidth and scalability for AI and cloud workloads.

Huawei'sAI roaming technologyenhances wireless network performance by optimizing roamingbehavior for client devices (STAs). Key features include:

Optimal roaming experience:Ensures seamless roaming for different types of STAs, improving wireless speeds by up to30%.

Flexible steering policies:Supports dynamic and differentiated steering based on STA profiles, making option BFALSE.

802.11V support:Requires STAs to support the 802.11V standard for efficient roaming.

The claim that roaming steering policies are inflexible is incorrect, as AI roaming leverages intelligent algorithms to adapt policies dynamically based on network conditions and device characteristics.

Understanding iStack Technology:

iStack is Huawei's stacking technology that allows multiple switches to be managed as a single logical device. This simplifies network configuration, management, and troubleshooting.

Dedicated Stack Ports or Stack Cards:

To enable iStack functionality, Huawei switches require either dedicated stack ports or stack cards. These ports/cards facilitate high-speed interconnection between stacked switches.

Benefits of iStack:

Simplifies network topology by reducing the number of managed devices.

Enhances scalability and reliability through unified management.

Conclusion:The statement is TRUE because dedicated stack ports or stack cards are required to support iStack technology.

Huawei’sFree Mobilitysolution providesconsistent network accessusingUser-Based Policy Control.

(B) True – User-Based Policy Control:

Ensures thatuser policies(VLAN, QoS, security) remainconsistentacross the network.

Users canmove freelyacross different subnets while maintainingthe same network access privileges.

Other options:

(A) IP Address-Based Control (False): Users' IP addresses may change, disrupting policy continuity.

(C) MAC Address-Based Control (False): MAC addresses aredevice-specific, limiting user mobility.

(D) Terminal-Based Control (False): Controls access perdevice, not per user.

MACsec(Media Access Control Security) is aLayer 2 security protocolthat provides end-to-end encryption for Ethernet frames. It ensuresconfidentiality, integrity, and authenticityof data on wired networks.

A (Service data encryption):Encrypts Ethernet frames to protect against eavesdropping.

B (Data frame integrity check):Prevents data tampering and corruption.

C (Replay protection):Detects and prevents replay attacks by using unique sequence numbers.

D (Data source authenticity verification):Ensures that received data is from a legitimate source by using cryptographic authentication.

Adefault routeis a special type of route used in routing tables to forward packets when no specific route matches the destination IP address. It acts as a "catch-all" route for traffic that does not match any other routes in the routing table.The default route is typically represented as0.0.0.0/0, where:

0.0.0.0represents any destination IP address.

/0indicates a subnet mask of 0 bits, meaning it applies to all possible IP addresses.

Default routes are commonly used in scenarios where a router needs to forward traffic to a gatewayor next-hop device for further processing. This simplifies routing table management, especially in networks with limited or centralized connectivity.
