Q3. Router R1, in ASN 11, learns a BGP route from BGP peer R22 in ASN 22. R1 and then uses BGP to advertise the route to R2, also in ASN 11. What ASNs would you see in the BGP table on R2 for this route?

c. The eBGP peer uses the same ASN as the local router.
d. The eBGP peer updates its AS_Path PA before sending updates to this router.
Q6. Which of the following is the primary motivation for using BGP between an Enterprise and its ISPs?
a. To influence the choice of best path (best route) for at least some routes
b. To avoid having to configure static routes
c. To allow redistribution of BGP routes into the IGP routing protocol
d. To monitor the size of the Internet BGP table
