You are building a new network for a small startup financial services company. Security is
paramount, so each organization within the company will have its own network segment
separated by a router. However, funds are limited, and you have been asked to keep costs to a
minimum.
You have acquired a used fiber optic switch and want to use it to create a fiber optic backbone
that interconnects all of the routers. You purchased several used single mode GBIC modules on
eBay that you will install in each router to allow them to connect to the switch.
Both the switch and the GBIC modules use MTRJ connectors. You connect each module to the
switch with 1 meter multimode patch cables.
Will this implementation work?

C) No, you shouldn’t use multimode patch cables with single mode GBIC modules.

eBay that you will install in each router to allow them to connect to the switch.
Both the switch and the GBIC modules use MTRJ connectors. You purchased several used 1
meter multimode patch cables from Amazon. However, when they arrived, you noticed that
they use LC connectors. Fortunately, with some force, you found that you are able to get the LC connectors on the cables to lock into the MTRJ connectors on the GBIC modules and on the
switch.
Will this implementation work?

A) No, you should purchase patch cables that use MT-RJ connectors.

While viewing the status of the interfaces on a Cisco switch, you see an abnormally large
number of CRC errors on one interface. This interface is connected to a user’s workstation
