Nokia Certified Network Associate – IP/MPLS Services — Question 9

Which of the following statements about the MED BGP path attribute is FALSE?

Answer options

• A. The MED BGP path attribute is transitive.
• B. The MED BGP path attribute is optional.
• C. Routes having lower values in their MED BGP path attribute are preferred.
• D. The MED BGP path attribute's value is set by a router at the edge of an AS.

Correct answer: A

Explanation

The correct answer is A because the MED (Multi-Exit Discriminator) attribute is actually non-transitive, meaning it is not propagated to other Autonomous Systems (AS). Options B, C, and D are true statements: MED is optional, lower values are preferred, and the value is set by routers at the edge of an AS.
