What type of LMI is referred to as Status-Inquiry LMI?

1. LMI from Frame Relay switch to router

2. LMI sent by router to Frame Relay switch

3. LMI that indicates network congestion

4. LMI for configuring virtual circuits

The correct answer is: LMI sent by router to Frame Relay switch

The term "Status-Inquiry LMI" specifically refers to the signaling process where a router sends an LMI message to the Frame Relay switch to request the status of virtual circuits and other network conditions. This inquiry is crucial for the router to understand the operational status and the current state of the routes it is managing. This type of LMI allows the router to gather important information about the virtual circuits it's communicating with, including whether they are operational or if there are any issues that might affect connectivity. By sending this inquiry, the router seeks to maintain an accurate view of the network's status, which is essential for effective traffic management and troubleshooting. The other options do not align with the concept of Status-Inquiry LMI. For instance, LMI from a Frame Relay switch typically indicates the operational status but does not involve active inquiry from the router's side. Similarly, LMI indicating network congestion or for configuring virtual circuits pertains to different functions that do not specifically fit the description of an inquiry initiated by the router. Thus, the nature of Status-Inquiry LMI directly points to the router's action in querying the switch.
