I believe the correct answer is B. "NBMA operation" is generally referring to running EIGRP on Frame Relay, where a hub site can have multiple spoke sites connecting to the same interface. In such situations you may need to modify how much bandwidth EIGRP can use for routing protocol packets.
I believe answer C is incorrect, because it talks about modifying the interface bandwidth value. That's not what the bandwidth-percent command does, but modifying the interface bandwidth may be one, not necessarily recommended, way of specifying how much bandwidth EIGRP is allowed. The IOS docs say: "EIGRP will use up to 50 percent of the bandwidth of a link, as defined by the bandwidth interface configuration command. This command may be used if some other fraction of the bandwidth is desired. Note that values greater than 100 percent may be configured. The configuration option may be useful if the bandwidth is set artificially low for other reasons." So I think answer C is trying to trick you by throwing the 50% in there, assuming that you know something is 50% but not really understanding what they are talking about. Bandwidth-percent modifies the percentage of total bandwidth that can be used by EIGRP, the default IS 50%.

What is the purpose of the IP bandwidth-percent EIGRP' command? a. It adjusts the percentage of bandwidth that EIGRP packets can use on all of the router's interfaces. b. It adjusts the percentage of bandwidth that EIGRP packets can use on an individual router interface. c. It overwrites the bandwidth setting on an interface to ensure that EIGRP packets receive 50% of the available bandwidth on the router's interface. d. It limits the % of bandwidth that EIGRP packets can use. The percentage cannot exceed 50% of the configured bandwidth on all of the router's interfaces. I am confused between answers b & c. Could someone clarify ?
