A co-worker is developing an implementation plan for a design that uses OSPF 2 and RIPv2 routing domains, with two routers redistributing between the two domains.The co- worker asks your help in choosing how to prevent domain loops by setting administrative distance.
Assuming all other related settings use defaults, which of the following would solve the domain loop problem?（）
A. The distance ospf intra - area 80 inter - area 80 OSPF subcommand
B. T he distance ospf external 80 OSPF subcommand
C. The distance ospf intra - area 180 inter - area 180 OSPF subcommand
D. The distance ospf external 180 OSPF subcommand

A network includes a RIPv2 domain, an EIGRP domain, and an OSPF domain. Each pair of routing domains has multiple routers redistributing routes between the p air of domains. The design requires that the redistribution configuration avoid matching based on prefix/length because of the trouble in maintaining such configurations. Which one of the following tools can be used in all three routing domains to attem pt to prevent domain loops?（）
A. Setting route tags
B. Setting the default administrative distance differently for internal and external routes
C. Setting administrative distance differently per route
D. Setting metrics much higher for all ext ernal routes than for all internal routes -

Router R1 is redistributing between two OSPF processes. Given the configuration shown, which includes all commands in the route map named fred, which of the following answers is true regarding the redistribution into OSPF process 1?（） router ospf 1 redistribute ospf 2 external 2 route - map fred ! route - map fred permit 10 match ip address 1 set metric - type type - 1
A. No routes are redistributed because a route cannot be both E1 and E2.
B. Only OSPF E2 routes in the OSPF 2 domain will be considered for redistribution.
C. Inside the OSPF 2 domain, any formerly E2 routes will become E1 routes.
D. Routes permitted by ACL 1 will be redistributed, regardless of whether the routes are E1 or E2 routes.
