Free Access Huawei H19-301_V4.0 New Release

Thefive-layer TCP/IP modelconsists of the following layers:

Application layer

Transport layer

Network layer

Data link layer

Physical layer

A. Application layer– Handles application-level protocols (e.g., HTTP, FTP).

B. Network layer– Handles logical addressing and routing (e.g., IP).

D. Transport layer– Manages end-to-end connections and reliability (e.g., TCP, UDP).

C. Radio layeris not part of the standard TCP/IP model — it's relevant in wireless physical-layer communication, butnot defined in the TCP/IP layering structure.

TheHuawei NetEngine AR6710-L14T2X4is a high-performance enterprise gateway router thatsupports more than just SD-WAN and switch convergence. It also supports:

WAN optimization

SRv6

Application-level routing

Integrated security (including firewall and IPS capabilities)

Wireless access and VPN features

This router is designed forconverged services,not limitedto only SD-WAN and switches.

Huawei’sWi-Fi Shield technologyis designed toenhance WLAN securityand includes features such as:

Unauthorized terminal detection and suppression

Data encryption and integrity protection

Air interface behavior analysisto block rogue APs or attackers

Contrary to the statement,Wi-Fi Shield prevents unauthorized terminals from accessing or parsing any data, making the correct answerFalse.

M-LAG (Multi-Chassis Link Aggregation Group) is a technology that implements link aggregation across two or more independent physical devices (i.e., switches).

It enables downstream devices (such as servers or switches) to connect to two upstream devices as if they were one logical device.

This allows for:

Active-active forwarding (traffic load balancing)

Device-level redundancy (if one upstream device fails, the other continues forwarding traffic)

Eth-Trunk refers to link aggregation but generally within a single device.

Stack creates a logical switch from multiple physical switches, but it does not address inter-device aggregation in the same distributed manner as M-LAG.

LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol for device discovery and has no role in link aggregation.
