The tunnel detection function can be used to check the tunnel status, for example, whether the tunnel is reachable. Which of the following mechanisms is used for GRE tunnel detection?
In a dual-link backup scenario, the active/standby link switchover mode is set to priority. When the active link recovers, the AP detects that the original active link has a higher priority and triggers a switchback. How many Echo intervals does the AP wait for before switching back to the original primary WAC?
Radio frequency identification (RFID) is a non-contact automatic identification technology that automatically identifies objects. Which of the following components are included in a typical RFID system?
During a project lifecycle, the______ document needs to be output after the high level design be output after the low level design is complete. (Enter the acronyms in capital letters.)
After RADIUS packet retransmission is triggered, if the device detects that the RADIUS server status is Down, the device marks the RADIUS server status as Down. If the maximum number of retransmissions has not been reached, which of the following will occur?
Drag the short-range wireless IoT technologies on the left to their corresponding descriptions on the right.
Which of the following statements are true about data collection of IMaster NCE-Campuslnslght? (Select All that Apply)
After traffic suppression is enabled on a Huawei WAC, the device monitors the rate of broadcast, multicast, and unknown unicast packets and compares the rate with the configured threshold. When the incoming traffic rate exceeds the configured threshold, the device discards the excess traffic.
Which of the following statements about the authentication rules of the RADIUS server are true?
Deploying user authentication points at the access layer achieves fine-grained permission management and high network security. However, as the network scale is rapidly expanding, problems arise, such as heavy configuration workloads and high O & M difficulties. To mitigate these problems, user authentication points can be moved upward from the access layer to the aggregation or core layer. In this way, authentication information across the entire network is centralized and the number of user authentication points is decreased, thereby reducing the configuration and maintenance workload.
Sticky STAs always associate with the AP that they initially connect to and da not proactively roam to a better one. Which of the following roaming optimization technologies is used to resolve the sticky STA problem?
Which of the following layers is not included in the overall networking logic of energy efficiency management in the loT solution?
Which of the following tools are commonly used for WLAN network planning, acceptance, or health evaluation? (Select All that Apply)
Which of the following statements are true about the site design in Huawei ' s CloudCampus Solution?
An IPv6 packet consists of three parts. Which of the following is not one of them?
In mesh networking, APs have different roles. Drag the AP roles on the left to the role descriptions on the right.
When calculating the number of APs, you can divide the total required bandwidth by the maximum bandwidth of a single AP.
In centralized gateway deployments, border nodes are used as gateways, facilitating centralized management and simplifying O & M. In distributed gateway deployments, edge nodes are used as gateways, facilitating network expansion.
In 802. IX authentication, if the RADIUS server has insufficient processing capability to parse a large number of EAP packets and complete authentication, the EAP______mode should be used. (Enter only lowercase letters.)
In DHCPv6 stateful autoconfiguration, if a DHCPv6 client receives Advertise messages from multiple DHCPv6 servers, the client selects the DHCPv6 server with the highest priority. Then which of the following type of messages does the client send to all DHCPv6 servers?
Either of the two APs that have established a mesh connection can send a Mesh Peering Close frame to the other AP to tear down the mesh connection.
On a campus network, which of the following problems may occur when you manually create a static VXLAN tunnel? (Select All that Apply)
Huawei ' s leader AP solution supports both Layer 2 and Layer 3 roaming for STAs.
STAs can roaming within the local site only when cloud APs are deployed at the same site, and the AP deployment distance is proper to ensure that the local cloud AP can receive air interfaces packets from the remote cloud AP.
On a WLAN, if PoE+ + power supply is used, the distance between a PoE switch and an AP can exceed 100 m.
After the HTTP domain name is entered in a browser, the user Is not redirected to the Portal URL. Which of the followings is the possible cause for this failure? (Select All that Apply)
A Wi-Fi RFID tag is a signal generator manufactured by tag vendors to help locate the objects. Which of the following types of tags can be located by Huawei devices?
VXLAN uses a VXLAN Network Identifier (VNI) field similar to a VLAN ID to identify users. The VNI field occupies 28 bits and supports up to 16M VXLAN segments.
In large-scale campus network design, which of the following security technologies are recommended to be deployed at the access layer?
Smart roaming enables STAs to promptly roam to neighboring APs with better signals, improving the WLAN roaming experience. When the WAC detects a sticky STA. it immediately triggers a smart roaming policy to enable the STA to associate with a better AP.
When planning WLAN outdoor coverage using external 2.4 GHz omnidirectional antennas with 3 dBi gain, what is the recommended coverage radius?
In cloud-based WAC management, d ' ter WACs register with iMaster NCE-Campus. administrators can remotely manage and control WACs and their connected Fit APs on enterpnse networks, enabling automatic deployment, service provisioning, monitoring, and OS.M of wireless networks. The WAC can obtain the IP address of iMaster NCE-Campus through multiple methods. Sort the methods in descending order of priority.
After a WLAN is deployed, the customer finds that STAs fail to roam. What are the possible causes?
The AP models are different. For example, the HAP model is AirEngine 5760-51, and the FAP model is AirEngine 6760-X1.
Which of the following statements are true about directional and omnidirectional antennas?
Which of the following statements are true about management frames on a mesh network?
To enable WPA3-incapable ST As to access a WPA3-conflgured network, the WI-FI Alliance defines the WPA3 transition mode in which WPA3 and WPA2 can coexist for a period of time in the future. This mode applies only to WPA3-Enterprise, not to WPA3-Personal.
Which of the following parameters must have the same settings for the 2.4 GHz and 5 GHz radios of an AP to implement band steering?
