The provided image displays the output of a show spanning-tree command. The section "Root ID" contains information about the Spanning Tree Protocol (STP) root bridge for this instance. The "Priority" field under "Root ID" shows a value of 32768. This value is in decimal format. The question requires this priority to be expressed in hexadecimal. The decimal value 32768 converts to 8000 in hexadecimal (32768 = 8 16³). Therefore, the bridge priority of the root bridge in hexadecimal is 8000.

B. 0: This is incorrect. A hexadecimal value of 0 would correspond to a decimal priority of 0, but the output explicitly shows the priority is 32768.

C. 9c49: This is incorrect. This value corresponds to the first part of the MAC address (9c49.eb00.0000) listed under the "Bridge ID", not the priority value.

D. 20009: This is incorrect. This hexadecimal value corresponds to the decimal value 131081, which has no relevance to the priority shown in the command output.

Section: "Displaying STP information" (Chapter 2: Spanning Tree Protocols)

Reference: This guide provides examples of the show spanning-tree command output. It confirms that the "Priority" field displays the decimal value of the bridge priority, which defaults to 32768. The guide states, "The bridge priority. The default is 32768." This confirms the value in the output is the standard decimal representation.

Section: show spanning-tree command description.

Reference: This document details the fields in the show spanning-tree output. The "Priority" field under "Root ID" is defined as the priority of the root bridge. The conversion from the displayed decimal value (32768) to hexadecimal (8000) is a standard numerical conversion required to answer the question.
