NEW QUESTION 53
As shown in the figure, the network has a loop because STP is not enabled. Which of the following phenomena may be bowed?

Hostreceive a large number of broadcasts

The device will generate a loop alarm

equipmentCPUOccupancy is too high

MA, CAddress table flapping

NEW QUESTION 54
Which description is correct about the label encapsulation format in MPLS? (Multiple choice)

The total length of a single MPLS label is 4 bytes (32 bits)

For Ethernet and PPP packets, the label stack is located between the layer 2 header and the data like a “underlay*”: when there is a VLAN tag, the MPLS header is placed between the Ethernet header and the VLAN tag

The S field in the label: 1 bit, used to identify whether the label is the bottom label of the stack, when the value is 1, it indicates the second-to-last label

The TTL field in the label is similar to the TTL (Time To Live.) in the IP packet, and it also has the effect of preventing loops.
