1.

The following is a correct statement of the spanning tree:

Adoption of the physical path redundancy to improve the reliability of the network bridge Adoption of the logical path redundancy to improve the reliability of the network bridge to eliminate bridging by blocking the links may exist in the network path loop when the current active path fails to restore active redundant network connectivity link

2.

The following statement on the STP is not correct

a switched network can have only one designated switch All switch ports are root port root switch ports are designated ports for all switching network switches the switch priority value as the smallest non-root switch

3.

STP protocol bridge ID consists of two parts, namely,

bridge priority The port ID bridge The MAC address of bridge The IP address of the bridge

4.

STP bridge ID in agreement with bits

8 32 48 64

5.

The following description of the principle of spanning tree protocol is correct

From all the switches in the network, select a switch as the root (Root) Calculate the switch to the shortest path to the root switch For each LAN, elect the root switch from the recent switch as the designated switch that is responsible forforwarding this data on the LAN non-root switch will choose the number of root port, the root port switch gives the path to the root switch isthe best path set

6.

In the STP protocol, which of the following factors will affect the election of the root switch?

switch priority switch port ID switch interface bandwidth MAC address of switch the IP address of the switch

7.

The following description of the advantages and disadvantages of spanning tree protocol is not correct

Spanning Tree Protocol to manage redundant links Spanning Tree Protocol to block redundant links, to prevent the generation of loop Spanning Tree Protocol to prevent the temporary loss of network connectivity Spanning Tree Protocol will enable Ethernet switch can work in the presence of physical loops in thenetwork environment

8.

Site A and Site B, respectively, and two ports connected to the switch, assuming that Site B does not send any messages, then site A to site B to send the first data packet, the following statements is correct

switch MAC address table cannot be found in site B of the destination port, it will discard the packet. Site B switch to learn the address and message in the Site B to connect the port to send out A switch to learn the site's address and broadcast packet out all ports from A switch to learn the site's address and port to receive packets from the outside in addition to otherbroadcast out all ports

9.

STP on the following statements is correct is

A switched network can have only one root switch All switch ports are root root port root switch ports are designated ports for all switching network switches the switch priority value becomes the root switch minimum

10.

In the STP, the switch port's role can be

Root port backup root port optional port Preliminary port Designated port
