What type of VTP advertisement does a VTP enabled switch request upon being reset or connected to the network for the first time?

Advertisement Request
VLAN Information Request
Advertisement Acquisition
Standard VLAN Announcement

The correct answer is: Advertisement Request

Upon being reset or initially connected to the network, a VTP (VLAN Trunking Protocol) enabled switch sends out a specific type of request known as a VLAN Information Request. This request is made to retrieve the current VLAN database from other switches functioning as VTP servers within the same VTP domain. The purpose of this request is to ensure that the switch can synchronize its VLAN information with the existing network configuration. By issuing a VLAN Information Request, the switch looks for a response from other VTP switches to obtain the necessary VLAN details, such as VLAN IDs and names, that are essential for proper network operation. This process is crucial in maintaining consistency and preventing misconfigurations in VLAN assignments across switches in a VTP domain. When a switch is newly connected or reset, it does not have any VLAN information, hence the need to request this data from neighboring switches effectively.
