What are two important guidelines for implementing VTP?

1. Enabling VTP pruning on a server will enable the feature for the entire management domain

2. Only configure management domain passwords on VTP servers when using secure mode VTP

3. All switches in the VTP domain must run the same version of VTP

4. CDP must be enabled on all switches in the VTP management domain

The correct answer is: Enabling VTP pruning on a server will enable the feature for the entire management domain

In the context of implementing VLAN Trunking Protocol (VTP), enabling VTP pruning on a server indeed affects the entire management domain. This feature is designed to optimize the use of bandwidth by reducing unnecessary VLAN traffic on trunk links. When VTP pruning is enabled on a VTP server, it propagates information to all switches in the VTP domain, thereby ensuring that only the VLANs that are active on specific switches are advertised across trunk links. Therefore, enabling this feature on one server has a cascading effect throughout the entire management domain, making it an essential guideline for proper implementation. The other options reflect different aspects of VTP configuration but do not accurately represent crucial guidelines for implementation. For instance, while it is advisable to maintain consistent versions of VTP across switches, not all VTP domain configurations require all switches to run the same version, provided they are compatible. Additionally, while securing management domain passwords is important, the context under which they are used can vary. Lastly, CDP (Cisco Discovery Protocol) is useful for network topology discovery and device communication but is not a requirement for VTP functioning, as VTP can operate independently of CDP. Thus, the correct understanding revolves around the unique impact of enabling VTP pruning on the
