When an OSPF design is planned, which implementation can help a router not have memory resource issues？（）

A. OSPF is not supported by the design

B. HSRP is not supported by the design

C. preempt tuning of the default gateway is needed

D. the design implements Layer 3 between the access switch and the distribution switch

A. Never use passive interfaces.

B. Use NSSA areas from the core down.

C. Use totally stub areas to stop type 3 LSAs.

D. Use the lowest Ethernet interface IP address as the router ID.

E. Tune OSPF timers to enable OSPF to achieve quicker convergence.

Route redistribution (RR) has become an integral part of IP network design as the res ult of a growing need for disseminating certain routes across routing protocol boundaries. By default, which description is true when redistributing routes from other routing protocols into OSPF？（）

A. Summarized routes are unacceptable

B. They will appe ar in the OSPF routing table as type E2 routes

C. Only routes with lower administrative distances will be imported

D. All imported routes are to be automatically summarized if possible

A.it reduces the number of required OSPF neighbor adjacencies

B.It reduces the types of LSAs that are generated

C.It is less CPU intensive for routers in the single area

D.It increases LSA response times.

E.It removes the need for virtual links

outing 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.to confine network instability to single areas of the network.

B.to reduce the complexity of router configuration

C.to speed up convergence

D.to lower costs by replacing routers with distribution layer switches

E.to decrease latency by increasing bandwidth

F.to reduce routing overhead

求翻译，谢谢！

A.No dynamic interior routing protocol can summarize as shown

B.Unless configured otherwise, EIGRP would automatically summa rize the prefixes as shown in the exhibit

C.With this IP addressing scheme, EIGRP can be manually configured to summarize prefixes at the specified summarization points

D.The IP address design lends itself to OSPF Each summarizing router would be an ABR, summarizing to the next area in the address hierarchy
