What is the cause of the errors?

You are trying to upgrade an existing 1Gb/s FC SAN that is using 62.5 micron multi-mode cable
from a tape library to a server that is 175 meters away to 2Gb/s Fibre Channel. After switching to
the 2Gb/s Fibre Channel equipment, a connection to the server cannot be maintained. When a
connection is made, numerous errors are reported. What is the cause of the errors?

You are looking at a Fibre Channel trace log and you notice that the class 2 communication
session between one initiator and target continually stops and then restarts. You suspect that
there is a flow control problem between this pair of devices. Which login communication session
would you analyze in the trace log for the number of flow control credits that have been allocated?

What storage event will occur as a result of this?

There are two datacenters separated by twelve (12) km with IP connections linking the two sites.
Site A is the primary production site, Site B is for test/development & disaster recovery. Site A
synchronously replicates data to Site B for disaster recovery purposes via a merged SAN fabric
between the two sites. The communication between the two sites is lost. What storage event will
occur as a result of this?

What is the most likely cause of the problem?

You have just completed installing, cabling, zoning, and device masking for a new server. HBA
configuration was successful, yet the host cannot see the storage after executing a device find
command. Investigation at the switch reveals that the host is not “seen” at the switch port. Light is
visible at either end of the fiber but no link light is seen on the switch. What is the most likely cause
of the problem?

Which option would allow for the addition of the new hosts while maintaining the redundant infrastructure at l

A customer has deployed redundant switched fabrics in a HA environment which also includes

non-HA, single-attached test servers. A new project requires additional connectivity for new HA
servers to be placed into production, but there are not enough free ports available in one of the
existing fabrics to complete the HA deployment. Which option would allow for the addition of the
new hosts while maintaining the redundant infrastructure at least cost?
