Refer to the exhibit. A network administrator is configuring PVST+ for the three switches. What will be a result of entering these commands?

• S1 will set the priority value for VLAN 20 to 24596.
• S2 will set the priority value for VLAN 10 to 24576.
• S1 will set the priority value for VLAN 10 to 0.
• S3 will set the priority value for VLAN 30 to 8192.

Explanation: In PVST+ configuration, the spanning-tree vlan vlan-id root primary global configuration mode command will set the priority for the switch to the predefined value of 24,576 or to the highest multiple of 4,096, less than the lowest bridge priority detected on the network. The spanning-tree vlan vlan-id root secondary global configuration mode command will set the priority for the switch to the predefined value of 28,672. Because S1 is configured with the priority value of 12,288 for VLAN 30, S3 has to be configured with the priority value of 8,192 (highest multiple of 4,096 but lower than 12,288) to become the root bridge for VLAN 30.
