A four-way cluster is attached to two fabrics. Each member has two HBAs connected to
each fabric. Each fabric has two subsystem connections. Each cluster member is a primary
for one application. All LUNs appear on all storage ports with workload equally distributed
across all. Each host has two dedicated HBAs for tape that can each see four independent
LTO II (35MB/s) tape drives. All files are large and involve sequential I/O. Performance
reporting shows a large read pending at the host during multi-threaded backup. What is the
most probably cause for the large read pending at the host?
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?
A. Add a new switch to the problem fabric to increase available ports on the switches.
B. Add a new switch to both fabrics to increase available ports on the switches.
C. Add ISL's between the existing fabrics to leverage all available ports on the switches.
D. Cascade the existing switches into a new director class switch and add the hosts to the director.
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?
A. 2Gb/s Fibre Channel must convert to LC from SC connectors
B. 2Gb/s Fibre Channel must use 50 micron multi-mode cable
C. 2Gb/s Fibre Channel cable length requires an optical splitter
D. 2Gb/s Fibre Channel cable length has been exceeded
The customer has an existing fabric switches installed from one manufacturer. They have
decided to add a redundant fabric using switches from a different manufacturer.
Interoperability is their main concern. What is important when considering interoperability in
You have noticed some unusual behavior in your storage environment. You need to
troubleshoot the problem and review the available options there are to resolve the issues
and to restore stability. What will restore stability to the environment?
A. Install system upgrades promptly after successful testing.
B. Align applications to information policy management requirements.
C. Limit collaboration with other organizations with similar storage networks and configurations.
D. An annual security audit should be performed and system logs should be scrutinized for unusual activity.
After a company experienced a localized disaster, the Business Continuance Plan was
reviewed. The plan was revised to include a Recovery Time Objective (RTO) of four (4)
hours and a Recovery Point Object (RPO) of one hour. What two (2) processes must be
implemented to support this requirement? (Choose two.)
A. mirrored snapshots of data and applications
B. backup tapes recovered from offsite storage
C. data snapshots from the previous day
D. operating system and application reinstallation media
The storage administrator has a request to add more storage to support added features on
an application. Which two (2) steps must be taken for the application to recognize the
added storage? (Choose two.)
A customer has a database server that processes a great deal of data very quickly. They
have identified a bottleneck in the storage subsystem and requested a change to the RAID
configuration. How would you configure the new RAID group? (Choose two.)
