• B.Adjust the power supply of the AP
• C.Adjust the AP's transmit power
• D.Adjust the angle of the AP antenna

Different messages use different message priorities.
Which of the following descriptions of message priority is incorrect?

• A.To maintain the packet priority as it passes through different networks, the priority field configured on the device must remain unchanged. Priority mapping cannot be performed.
• B.The 802.11 packets sent by the STA carry the UP priority or DSCP priority.
• C.To maintain the priority of packets as they pass through different networks, you need to configure a mapping between priority fields on the device.
• D.VLAN packets in a wired network use 802.1p priority, and IP packets use DSCP priority.

The biggest change in the optoelectronic hybrid cable 2.0 is that the optoelectronic hybrid switch port changes from optical and electrical separation to optical and electrical integration. The structural optimization makes the splicing and use of the optoelectronic hybrid cable easier, while doubling the density of the optoelectronic ports.

• A.Correct
• B.Error

In the LAN-WAN convergence scenario, which of the following descriptions of RR deployment design principles is incorrect? ( )

• A.Choose an independent RR if possible. In an independent RR scenario, a single device can be deployed:
• B.The Edge should be dual-uplinked to two RR devices to achieve egress backup;
• C.RR must be redundantly configured. A network must have at least two RR devices to prevent a single RR device from causing network-wide service interruption if the RR device fails.
• D.Use the RR model recommended in the specification list:

FireHunter is a high-performance APT threat detection system launched by Huawei. Building on traditional security detection technologies, FireHunter incorporates multi-engine virtual detection technology to analyze and collect static and dynamic software behaviors. Leveraging a unique behavioral pattern library, FireHunter accurately identifies malicious files and C&C connections transmitted across the network, effectively preventing the spread of unknown threats.

• A.Correct
• B.Error
