What is causing the problem?
You receive a ticket from a database group which is complaining about slow access to storage on
only one particular server, as compared to other servers in an active-active cluster. You verify
zoning and LUN masking which are fine. On the FC switch, you verify link speed, errors, and
throughput for the FC switch ports used by this server. There are no errors on the ports and the
link speed is the same as on the switch ports used by other servers in the cluster. You notice that
on one port on the FC switch used by this server, that there is no throughput at all.

What is the minimum length of fiber to use in a fabric?
What is the minimum length of fiber to use in a fabric?
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?
Which storage networking environment accesses the file system through a local area network?
Which storage networking environment accesses the file system through a local area network?
which RAID level should you use to create this LUN?
You have been asked to create a LUN on a storage array that is comprised of 7,200 rpm SATA
drives. Each drive is rated at 100 IOPS. The LUN should provide a minimum of 1100 IOPS and
withstand multiple drive failures using the least number of drives.
How many drives and which RAID level should you use to create this LUN?
What are two results of this change?
A customer has a demanding application which currently uses two HBAs. They will access the
same LUNs on the same storage ports but they will add four HBAs to the Host. This increases the
fan-in ratio of the host. What are two results of this change?
Which two (2) business management requirements will be met by the implementation?
A customer’s database environment includes remote synchronous mirroring across a DWDM link.
Which two (2) business management requirements will be met by the implementation? (Choose
two.)
Which two sub-components are required in a specialized NAS operating system?
Which two sub-components are required in a specialized NAS operating system? (Choose two.)
where will the oversubscribed link(s) occur?
The customer application requires a 50/50 R/W ratio with 100 MBps throughput requirements for
each direction of the link. The application servers will simultaneously sustain these data rates
across all LUNs in parallel.
Referring to the exhibit, where will the oversubscribed link(s) occur?
How must the volume be started?
A Database Administrator (DBA) has created a logical volume using disks from three different
arrays. The data from each array is synchronously replicated over a fibre channel link to one of
three arrays in a remote location. There is a rolling disaster which caused the remote links
between the arrays to fail at different times. The DBA is trying to start the volume at the remote
site. How must the volume be started?
