Answer: A
Q3. Refer to the exhibit.
Switch A, B, and C are trunked together and have been properly configured for VTP. Switch C receives VLAN information from the VTP server Switch A, but Switch B does not receive any VLAN information. What is the most probable cause of this behavior?
A. Switch B is configured in transparent mode.
B. Switch B is configured with an access port to Switch A, while Switch C is configured with a trunk port to Switch B.
C. The VTP revision number of the Switch B is higher than that of Switch A.
D. The trunk between Switch A and Switch B is misconfigured.
Answer: A
Q4. After reviewing UDLD status on switch ports, an engineer notices that the." Which statement describes what this indicates about the status of the port?
A. The port is fully operational and no known issues are detected.
B. The bidirectional status of "unknown" indicates that the port will go into the disabled state because it stopped receiving UDLD packets from its neighbor.
C. UDLD moved into aggressive mode after inconsistent acknowledgements were detected.
D. The UDLD port is placed in the "unknown" state for 5 seconds until the next UDLD packet is received on the interface.
Answer: A
Q5. Refer to the exhibit.

C. BPDUignore
D. BPDUguard
E. BPDUdisable
Answer: B
