Assuming that all switches in a network have the default bridge priority for each MST instance, what effect does the command spanning-tree mst 10 root seconday have when entered on a single switch?

Assuming that all switches in a network have the default bridge priority for each MST instance, what effect does the command spanning-tree mst 10 root seconday have when entered on a single switch?

• sets the bridge priority on the switch to 28672 for MST instance 10
• sets the bridge priority on the switch to 24586 for MST instance 10
• sets the bridge priority on the switch to 24582 for MST instance 10
• sets the bridge priority on the switch to 24576 for MST instance 10

Explanation: In MST configuration, an MST instance priority can be defined in one of two methods:
spanning-tree mst instance-number priority priority , where the priority is a value between 0 and 61,440, in increments of 4096
spanning-tree mst instance-number root { primary | secondary }[ diameter diameter ], where the primary keyword sets the priority to 24,576, and the secondary keyword sets the priority to 28,672
