Exam 2V0-41.23 topic 1 question 39 discussion

AS-Path Prepend is a BGP attribute that influences the path selection by adding additional occurrences of the autonomous system (AS) number to the AS path. This can make a route less preferred by other BGP routers, effectively influencing the traffic to take an alternate path. MED (Multi-Exit Discriminator) is another BGP attribute that is used to influence the route path. It is a metric that represents the "cost" of reaching a specific BGP route. A lower MED value indicates a more preferred route.
