You need to ensure that messages sent to users in Wingtip Toys by users in Tailspin Toys will be sent by using the Lotus Notes connector. What should you do?

A.
Configure the cost of the SMTP connector on Exch1 to be 20.

B.
Configure the cost of the Lotus Notes connector on Exch2 to be 5.

C.
Configure a Lotus Notes connector between Exch1 and Notes1.

D.
Configure the SMTP connector on Exch1 to allow a maximum message size of 1,000 KB for outgoing messages.

E.

Explanation:

The smtp route will be taken irrespective unless the Lotus notes connector is configured for an address space of *foobar.com and has
a lower cost than the smtp route over the internet. Hence setting the cost on the connector from the Bridgehead Exch1 alone will not
be enough. Note it Exch1 not 2 as the answer in B says
