Question 86

Regarding MSTP, the correct statement is

A.MSTP is defined in 802.1s^ which can not only meet fast convergence, but also achieve load sharing

B.A VLAN in MSTP can be mapped to multiple spanning tree instances

C.A spanning tree instance in MSTP can contain multiple VLANs

D.The basic idea of MSTP is to calculate a spanning tree for each VLAN, and each tree corresponds to a spanning tree instance

Question 87

If customers prefer to use TACACS+ protocol instead of RADIUS to complete user access authentication, this may be because _______

A.TACACS+ adopts UDP protocol, high network transmission efficiency

B.The TACACS+ protocol message is simple, which can be combined with authentication and authorization, or separated easily

C.TACACS+ protocol uses TCP reliable transmission

D.TACACS+ protocol message subject part is all encrypted, high security

Question 88

The figure shows the networking application of SmartLink and Monitor Link. The Smart Link group is configured on the switch SWD, and the Monitor Link group is configured on the switch SWB and switch SWC. The switch SWB is connected to the switch SWA port as the Monitor Link uplink port, and the switch SWB is connected to the switch SWD port. Monitor Link downlink port: The opposite port of the downlink port is the switch SWDSmart Link group port, which can be known from the above information

A.The link of the switch SWB uplink switch SWA is Down, and the status of the Smart Link group of the corresponding port of the switch SWD may not change

B.The link of the switch SWD upstream switch SWB is Down, and the status of the upstream port of the switch SWBMonitor Link group must change

C.The link of the upstream switch SWA of the switch SWB is Down, and the status of the Smart Link group of the corresponding port of the switch SWD must change

D.The link of the upstream switch SWB of the switch SWD is Down, and the status of the upstream port of the switch SWBMonitor Link group may not change

Question 89

Regarding the comparison of the calculation convergence of RSTP and STP, the correct statement is

A.Compared with STP, RSTP defines the basic port fast switching mechanism, so that the port connected to the host quickly enters the forwarding state

B.Compared with STP, RSTP defines a fast root port switching mechanism, which can make Altmate quickly become a new root port state when there is an obstacle to the port.

C.Compared with STP, RSTP defines a fast switching mechanism for designated ports, which can make the designated port enter the forwarding state without waiting for twice the Forward Delay time.

D.If STP wants to shorten the convergence time, you can only configure a smaller FORWARD Delay time, but it will affect the stability of the network

Question 90

Which of the following messages are TACACS+ authentication messages

A.Continue

B.Request

C.start

D.Rsponse
