In BGP path selection, which aspect is described as the overall attribute set controlling routing decisions?

• A. NEXT_HOP
• B. AS_PATH
• C. LOCAL_PREF
• D. ATTRIBUTES

Answer: (D)

BGP decides which route to install by examining a bundle of path attributes carried with each route. These attributes describe the route’s history and desirability, and they are evaluated in a specific order to pick the best path. The term for this complete collection is the path attributes, or simply the attributes set. Individual attributes like NEXT_HOP, AS_PATH, and LOCAL_PREF are parts of that set, but it’s the entire attributes collection that governs routing decisions. So, the overall attribute set is the correct description.
