Option A

Option B

Option C

Option D

A new neighbor exists on the link.

The cost of a link to an existing neighbor has changed.

IS-IS sends link-state PDUs at random intervals.

NO.39 Referring to the exhibit, which two statements about BGP prefixes advertised by R1 to AS 65501
are true? (Choose two.)

R1 will modify the originator ID attribute in prefixes advertised to AS 65501
