Question 513

Regarding the DSCP field, the following statement is incorrect: single selection

The DSCP value can be 0, and packets use the default forwarding mechanism when 0

When the value of DSCP is EF, it indicates that the data belongs to the accelerated forwarding class.

In addition to indicating the priority of the data, DSCP can also indicate the probability of data being discarded.

DSCP divides data into 8 priorities.

Question 514

The following description of VLANs in Ethernet is correct?

VLANs do not support bulk creation on devices

The range of VLANs is 0 to 4096

The default reserved VLANs for Huawei devices are 4000~4010

VLANs can be extended through QinQ technology.

Auto-negotiate mode is to obtain the maximum interface rate and operating mode, the network administrator configures all Ethernet interface rates of a working switch to 10OMbps, and the operating mode is configured as Full-duplex, when a network card is configured After the auto- negotiate workstation is connected to the switch, the negotiation result is that the interface rate is 10OMbps and the working mode is half-duplex, which of the following explanations is the most reasonable for this phenomenon?

The problem is on the workstation's NIC, mostly due to the aging of the NIC driver on the workstation , which causes the workstation NIC to learn the interface rate and operating mode configured on the switch

Port rate negotiation is negotiated through the initial port sending FLP , and the operating mode is not negotiated through FLP

STP initializes the port into the blocking state, causing auto-negotiation to fail, so the port should be configured as an edge port

At higher port rates and operating modes, the workstation's network interface card cannot be configured as auto-negotiate

Question 518

IPV6 multicast introduces the concept of multicast scope, which of the following ways is the multicast scope concept implemented? Multi-select

When the group shake source sends IP6 multicast data, the TTL value of the packet is set to limit the transmission range of the group shake

There is a special field in the IPv6 multicast address that specifies the propagation range of multicast.

Multicast scope is just a concept of spreading scope, and there is no specific technical implementation.

During network configuration, the administrator uses the configuration command at the edge of the network to limit the multicast scope.
