   How does the maximum-paths feature interact with the BGP path selection algorithm?

   • AIt only works for iBGP paths
   • BIt allows multiple paths that are equal according to the algorithm to be installed
   • CIt changes the order of the path selection criteria
   • DIt bypasses the path selection algorithm entirely

   What is the primary purpose of the BGP path selection algorithm?

   • ATo calculate the optimal path based on the IGP metric to the destination network
   • BTo choose the single best route to a destination from multiple learned paths
   • CTo determine the shortest path based on the physical distance between routers
   • DTo select all equal-cost paths and load balance traffic across them

   A service provider operates a dual-homed BGP network with two upstream providers. The network team wants all outbound traffic for a specific customer prefix to prefer the link to Provider A, regardless of the AS path length or local preference values learned from either provider. The team has already configured a route map on the neighbor statements for both providers. Which BGP attribute should be set in the route map to achieve this requirement?

   • ASet MED to a lower value on the Provider A neighbor
   • BSet local preference to a higher value on the Provider A neighbor
   • CSet weight to a higher value on the Provider A neighbor
   • DSet the AS path prepend on the Provider B neighbor

   What does the 'maximum-paths' command in BGP allow a router to do?

   • AChange the administrative distance of BGP routes
   • BAllow BGP to select a path with a longer AS path
   • CInstall multiple equal-cost paths in the routing table for load balancing
   • DAdvertise multiple paths for the same prefix to a neighbor
