JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing — Question 37

Using industry best practices, which two BGP attributes would you modify to influence how traffic enters your network? (Choose two)

Answer options

• A. AS Path
• B. Local Preference
• C. Next Hop
• D. MED

Correct answer: A, D

Explanation

Modifying the AS Path can influence the route selection process by affecting the path length. The Multi-Exit Discriminator (MED) is used to indicate the preferred entry point into an autonomous system from a neighboring AS, making it effective for influencing incoming traffic. The other options, Local Preference and Next Hop, do not directly impact how traffic enters the network from external sources.
