Show Suggested Answer

Suggested Answer: A, D

The MED (Multi-Exit Discriminator) is an optional, non-transitive attribute used to influence the exit path. MED is considered after attributes such as Local-Preference, AS-Path, and Origin during route selection. By default, if a MED value is missing, it is treated as 0 unless the bestroute med-none-as-maximum command is configured to treat it as 4294967295 .

I think option A is correct because I remember that MED is considered after Local Preference and AS Path in the BGP decision process.
