这题答案是不是错了

Which command shows your active Telnet connections?
A. show session
B. show cdp neighbors
C. show users
D. show queue
答案是A

但我在模拟器看不到东西,用show user 可以看到东西
Router#show sess
% No connections open
Router#show user
    Line       User       Host(s)              Idle       Location
   0 con 0                idle                 00:00:21
* 67 vty 0                idle                 00:00:00 192.168.1.2
  Interface    User               Mode         Idle     Peer Address
Router#

Which two states are the port states when RSTP has converged?(choose two)
A. blocking
B. learning
C. disabled
D. forwarding
E. listening
Answer: AD
Explanation/Reference:
那两个是收敛后的RSTP状态，AD

STP有5种状态blocking, listening, disabled, learning, forwarding,而RSTP不是只有3种状态吗,forwarding learning,discarding,这里为什么会选个blocking?

show session 是看active Telnet connections
show user 只是看用户
例：
R1#show sessions
Conn Host                Address             Byte  Idle Conn Name
*  1 192.168.1.200       192.168.1.200          0     0 192.168.1.200

A. blocking

收敛的最终结果就只有blocking或者forwarding
