What is the default priority value for a Spanning Tree Bridge ID?
- 16384
- 32768 ✓
- 8192
- 4096
Correct answer: 32768
The default Spanning Tree Protocol (STP) bridge priority is 32768, as defined in IEEE 802.1D. This value serves as the middle of the priority range (0 to 65535) so administrators can easily raise or lower it in increments of 4096. Option A (16384) is a valid priority value that can be configured but is not the default. Option C (8192) and Option D (4096) are also configurable values below the default, often used to force a switch to become the root bridge, but neither is the factory default.
