Which statement Is correct regarding the DR election process In this OSPF implementation?
A.
Both the CE5 and PE6 routers are DROTHERs
B.
PE5 is the OSPFv2 DR for the GigabitEthernet link between PE5 and PE6
C.
PE6 is the OSPFv2 and OSPFv3 DR for the GigabitEthernet link between PE5 and PE6
D.
PE6 is the DR for the GigabitEthernet link between PE5 and PE6 because it has a higher
OSPF priority

Passed exam on 20/Dec/2015! OSPFv2 and OSPFv3 Routing in Service Provider Environments, IS-IS, IPv4, and IPv6 in Service Provider Environments, BGP Routing in Service Provider Environments, Route Manipulations in Service Provider Environments, High Availability Routing Features are the main topics of the exam. Used passleader 642-883 exam dumps (http://www.passleader.com/642-883.html) and got all new questions!!!
