Which type of VTP advertisement informs adjacent switches of the current VTP domain name and revision number?

  1. Summary advertisement

  2. Subset advertisement

  3. VLAN advertisement

  4. Configuration advertisement

The correct answer is: Summary advertisement

The correct choice is the summary advertisement. This type of VTP (VLAN Trunking Protocol) advertisement serves to inform adjacent switches of essential information about the VTP domain. Specifically, it includes the current VTP domain name and the revision number, which helps ensure that all switches in the domain are synchronized with the same configuration information. In a VTP environment, summary advertisements are sent every five minutes or immediately when there is a change. They provide crucial details about the overall configuration of the VTP domain, allowing switches to determine whether their local configuration is up to date with the rest of the network. Configuration advertisements are focused on different aspects of the VTP information, such as VLAN configuration changes, and subset advertisements transmit information about specific VLANs. VLAN advertisements specifically deal with VLAN-specific information but do not convey the overarching details of the VTP domain name and revision number. Thus, understanding the role of summary advertisements is key to managing and maintaining VTP configurations effectively.
