MACsec is an important feature to make sure security and reliability. Which of the following routers can support MACsec?
Correct Answer:
BCD
MACsec (Media Access Control Security)is a Layer 2 encryption protocol that ensures secure and reliable communication over Ethernet links. Among Huawei'sNetEngine 8000 series routers, the following models support MACsec:
NetEngine 8000 M6:High-performance router with MACsec support for secure WAN connections.
NetEngine 8000 MIC:Modular interface card-based router with MACsec capabilities. NetEngine 8000 F1A:Fixed configuration router supporting MACsec for secure access links.
TheNetEngine 8000 MIAdoes not support MACsec, making it unsuitable for scenarios requiring Layer 2 encryption.

In order to simplify Huawei many access switches network configuration, we need to use dedicated stack ports or stack cards with iStack technology to support.
Correct Answer:
A
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.
