第9题:
All ports will temporarily transition to the learning state for a period equal to the max age timer plus the forward delay interval.
All ports will transition temporarily to the learning state for a period equal to the forward delay interval.
The default aging time for MAC address entries will be reduced for a period of the max age timer plus the forward delay interval.
The default hello time for configuration BDPUs will be reduced for the period of the max age timer.
第10题:
802.1D and 802.1w interoperate only when the 802.1D STP domain supports rapid convergence.
Ports leading to 802.1D devices will run in compatibility mode, while the rest of the ports will run in 802.1w mode.
This is an invalid configuration and a partial migration cannot be done.
The bridge timers will be set to match the 802.1D devices.
A secondary root bridge will always be populated within the 802.1D domain.
If the root bridge is selected within the 802.1D domain, the whole STP domain will run in 802.1D compatibility mode.
In partially migrated 802.1w networks, it is recommended to keep the STP diameter below 4.

to protect against user-side loops
in order to support business applications
because of the risk of lost connectivity without STP
