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%.

Subject: EIGRP Question [7:73068]
You are configuring EIGRP for NBMA operation. 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 ?
