The router must have one routing protocol configured, but configuration for both routing protocols is not necessaryB. The router must hav e at least one working link connected to each routing domainC. The redistribute command must be configured under EIGRP to send the routes to OSPFD. The redistribute command should be configured under OSPF to take routes from EIGRP into OSPF

2.Refer to the exhibit. Which statement about dynamic routing protocols for this network is true? ()A.No dynamic interior routing protocol can summarize as shownB.Unless configured otherwise, EIGRP would automatically summa rize the prefixes as shown in the exhibitC.With this IP addressing scheme, EIGRP can be manually configured to summarize prefixes at the specified summarization pointsD.The IP address design lends itself to OSPF Each summarizing router would be an ABR, summarizing to the next area in the address hierarchy

3.Which two statements about route redistribution when implementing OSPF are true?()A. Routes learned using any IP routing protocol can only be redistributed into non IP routing protocols.B. OSPF can import routes learned using EIGRP, RIP, and IS - IS.C. OSPF routes cannot be exported into EIGRP, RIP, an d IS - IS.D. At the interdomain level, OSPF cannot import routes learned using BGP.E. OSPF routes can be exported into BGP.

4.One of the most important characteristics of OSPF is Multiple areas. Which statement best describes why this feature is such an important enhancement to earlier routing protocols?()A. The network domain, when divided into areas, allows for the use of both IANA classful addressing and private addressing.B. The use of multiple areas allows for the use of prioritization.C. All computation is kept within the area, with minimum communication between the areas,allowing the network to scale to larger sizes.D. It is easier to implement security.
