Refer to the exhibit. In this network， R1 is configured not to perform autosummarization within EIGRP. What routes will R3 learn from R2 through EIGRP？（）
A.172.30.1.0/24 and 10.1.2.0/24； EIGRP only performs autosummarization at the edge between two major networks.
B.172.30.0.0/16 and 10.1.2.0/24； R2 will perform autosummarization， although R1 will not.
C.Since R2 is configured without autosummarization， it will not propagate the 172.30.1.0/24 route.
D.172.30.0.0/8 and 10.0.0.0/8.
A.loop guard
B.storm control

A.The IOS default is for a last-hop router to trigger a switch to the shortest path tree as soon as a new source is detected on the shared tree.
B.The IOS default is for every one of the routers on the shared tree to trigger a switch to the shortest path tree as soon as a new source is detected on the shared tree.
C.The default behavior of switching to the shortest path tree as soon as a new source is detected on the shared tree can be disabled by setting the value in the ip pim spt-threshold command to "infinity."
D.The default behavior of switching to the shortest path tree as soon as a new source is detected on the shared tree can be disabled by setting the value in the ip pim spt-threshold command to "zero."
Refer to the exhibit. In this network， R1 has been configured to advertise a summary route， 192.168.0.0/22， to R2. R2 has been configured to advertise a summary route， 192.168.0.0/21， to R1. Both routers have been configured to remove the discard route （the route to null created when a summary route is configured） by setting the administrative distance of the discard route to 255.What will happen if R1 receives a packet destined to 192.168.3.1？（）
A.The packet will loop between R1 and R2.
B.It is not possible to set the administrative distance on a summary to 255.
C.The packet will be forwarded to R2， where it will be routed to null0.
D.The packet will be dropped by R1， since there is no route to 192.168.3.1.
