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
Which statement about a none zero value for the load metric (k2) for EIGRP is true?() A.
