200-101 Question #152: Real Exam Question with Answer & Explanation

Question

Options

• AVTP works at Layer 3 of the OSI model and requires that a management VLAN IP address be configured.
• BWhen properly configured, VTP minimizes VLAN misconfigurations and configuration inconsistencies.
• CWhen properly configured, VTP maintains VLAN configuration consistency and accelerates trunk link negotiation.
• DEach broadcast domain on a switch can have its own unique VTP domain.
• EVTP pruning is used to increase available bandwidth in trunk links.
• FTo configure a switch to be part of two VTP domains, each domain must have its own passwords.
• GClient, server, and transparent are valid VTP modes.

Explanation

B is correct: VTP propagates VLAN database changes from the VTP server to all clients in the domain, preventing misconfigurations and inconsistencies. E is correct: VTP pruning stops unnecessary flooded traffic (broadcasts, multicasts, unknown unicasts) from being sent over trunk links to switches that have no ports in that VLAN, freeing up bandwidth. G is correct: the three valid VTP modes are server (can create/modify/delete VLANs), client (receives updates, cannot modify), and transparent (forwards VTP messages but maintains its own local VLAN database). A is incorrect: VTP operates at Layer 2, not Layer 3-no IP address is required. C is incorrect: trunk link negotiation is handled by DTP (Dynamic Trunking Protocol), not VTP. D is incorrect: a switch belongs to only one VTP domain at a time. F is incorrect: a switch cannot simultaneously belong to two VTP domains.
