Drag and drop the OSPF adjacency states from the left onto the correct descriptions on the right.

Question

Exhibit

Explanation

The exhibit image, detailing a network topology with route redistribution configurations, does not provide the visual elements (OSPF adjacency states or their descriptions) required to answer the drag-and-drop question about OSPF adjacency states.

Approach. As the question asks to 'Drag and drop the OSPF adjacency states from the left onto the correct descriptions on the right,' the correct approach is to identify the OSPF adjacency states and their corresponding descriptions within the provided exhibit. However, the exhibit images do not contain any visual representations or textual lists of OSPF adjacency states (such as Down, Init, ExStart, Exchange, Loading, Full) nor their descriptions for a drag-and-drop interaction. The images exclusively depict a network topology and router configuration related to route redistribution, prefix-lists, and route-maps. Therefore, based on the provided exhibit, it is impossible to correctly perform the requested drag-and-drop operation, rendering the question unanswerable with the given materials.

Common mistakes.

• common_mistake. Any attempt to answer the stated question about 'OSPF adjacency states' by making assumptions or extrapolating from the provided network diagram and configuration snippet would be incorrect. The exhibit simply lacks the specific drag targets and descriptions required by the question. For instance, trying to infer adjacency states from router connections shown in the topology, or guessing at what descriptions might be associated with certain states, would not align with the format of a drag-and-drop question that requires specific interactive elements to be present. Without the actual OSPF adjacency states and their descriptions in the exhibit, any selection would be arbitrary and unverified.

Concept tested. The stated question explicitly aims to test the candidate's knowledge of the OSPF neighbor discovery and adjacency formation process, specifically the different OSPF adjacency states (e.g., Down, Init, Two-Way, ExStart, Exchange, Loading, Full) and their meanings. However, the provided exhibit images, if intended for a different question, would test concepts such as route redistribution between different routing protocols (EIGRP into OSPF), the application and logic of route-maps for controlling redistribution (including deny and permit statements, and setting tag values), and the use of IP prefix-lists for granular route filtering based on network address and mask length (using the 'ie' keyword).
