## Common Questions

Match user requests to endpoints in references/api-spec.lap. Key patterns:
- "List all expressRouteCrossConnections?" -> GET /subscriptions/{subscriptionId}/providers/Microsoft.Network/expressRouteCrossConnections
- "List all expressRouteCrossConnections?" -> GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections
- "Get expressRouteCrossConnection details?" -> GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}
- "Update a expressRouteCrossConnection?" -> PUT /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}
- "Partially update a expressRouteCrossConnection?" -> PATCH /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}
- "List all peerings?" -> GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}/peerings
- "Delete a peering?" -> DELETE /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}/peerings/{peeringName}
- "Get peering details?" -> GET /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}/peerings/{peeringName}
- "Update a peering?" -> PUT /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCrossConnections/{crossConnectionName}/peerings/{peeringName}
- "How to authenticate?" -> See Auth section
