A company has a BGP network and a BGP route of 196.27.125.0/24 that
should be propagated to all of the devices. The route is not now in any of the routing tables. The
administrator determines that an access list is the cause of the problem. The administrator changes the
access list to allow this route, but the route still does not appear in any of the routing tables. What should
be done to propagate this route?
A. Clear the BGP session.
B. Use the release BGP routing command.
C. Use the service-policy command to adjust the QOS policy to allow the route to propagate.
D. Change both the inbound and outbound policy related to this route.

Which two statements about the IS-IS routing protocol are true? (Choose
two.)
A. In the IS-IS routing domain, routers may have adjacencies with other routers on multipoint links.
B. IS-IS metrics are based on delay, bandwidth, reliability, load, and MTU.
C. Level 1 routers learn about paths within the areas that the routers are connected to.
D. Level 2 routers are equivalent to ABRs in OSPF and learn about paths both within and between areas.
E. Level 1 and Level 2 routing is a function of ES-IS.
