IN QOS DESIGN, THE DESCRIPTION OF THE DESIGN PRINCIPLES OF TRAFFIC SCHEDULING IS INCORRECT ()

• A.For TCP-based services, the queue must be configured with WRED dropping to avoid TCP global synchronization
• B.Unless the business has special requirements, some parameters of the scheduling policy should be defaulted as much as possible
• C.Core services and video-voice services should ensure the absolute priority of forwarding and use PQ scheduling
• D.Maintain the principle of uniformity in the scheduling strategy of the whole network, and use templated deployment as much as possible to facilitate network management
• E.The current QoS policy needs to take into account the subsequent expansion of the network
• F.LPQ/WFQ scheduling strategies can be used to avoid low-priority services not being able to obtain bandwidth resources

The maximum MCS supported by WIFI6 is:

• A.MCS11
• B.MCS9
• C.MCS7
• D.MCS13

In the LAN-WAN convergence scenario, the description of RR deployment design principles is wrong ()

• A.The RR must be redundant, and at least two RR devices must exist on the live network. Prevent network-wide service interruption caused by the failure of only one RR device on the entire network.
• B.Use the RR model recommended in the specification list;
• C.The Edge should be dual-uplink to the two RR devices to achieve egress backup;
• D.Try to choose an independent RR, which can be deployed on a single device in the independent RR scenario.

In the WLAN scenario, the following statements are wrong for demand collection ()

• A.Coverage are answer confirm the key coverage area (such as office, conference room, etc.) and common coverage area (such as stairs, toilets, etc.) required by the customer
• B.Bandwidth requirements: the main types of services planned by the customer and the bandwidth requirements for each user
• C.Number of concurrent users: the total number of terminals connected in the current coverage area, and how many people in the coverage area are planned to be connected at the same time
• D.Pay the signal field strength requirements in the area, for example, -40dBm~-65dBm in key areas, and
  >-75dBm in ordinary areas

In the campus SDN solution, the statement about the distributed gateway solution is wrong ()

• A.Distributed gateway - VxLAN to access, independent AC scenario, for wireless traffic, local forwarding mode is not recommended.
• B.The VTEP device is both an L2 gateway and an L3 gateway. The non-gateway node is not aware of the VXLAN tunnel and acts only as the forwarding node for VXLAN packets.
• C.Distributed gateway - VxLAN to aggregation, AC on the board, the wireless traffic service accompanying policy is executed on the edge, and tunnel forwarding is recommended.
• D.Distributed gateway - VxLAN to access, independent AC scenario, from the edge to the VN, on the edge to execute the service accompanying policy (the edge needs to subscribe to the IP-Group service), the current solution has supported automatic deployment.
