I cleared exam yesterday and passes it. It was really
hard. I did not find any dumps for this exam. some
of the questions from exams are there. I thank to
all the dumpers who all sent their brain dumps to

An FCIP between two sites with MDS directors was successfully
implemented. Dual FCIP links were connected between
the two geographically separate sites. Abc .com was
running a highly available IP network utilizing the
HSRP protocol between their ingress/egress routers.
Recently a network event caused Abc .com IT Networking
team to change the IP load balancing/HA configuration
from HSRP to VRRP. Since making the change the FCIP
links have either been down, or worked only intermittently.
Why would the change to the IP load balancing/HA configuration
cause this behavior?
A. The VRRP needs to be implemented on the MDS switches
B. The VRRP protocol will represent the inbound link
as a VIP
C. The HSRP and VRRP protocols make no difference
with the MDS FCIP link
D. The VRRP protocol is encrypting all of the FCIP
traffic and striping the FCIP headers as part of the
Abc .com uses ControlCenter SAN Manager to manage
their fabric. Some of the SAN administrators prefer
to use switch native tools such as command line to
do zoning. You have been asked to make zoning changes
to the SAN. What will you do?
A. Activate zoneset using SAN Manager before any zoning
B. Re-discover the switches in SAN Manager before
C. Use command line to export zones to SAN Manager
D. Zone using command line and export zones to SAN
Abc .com has a performance issue on their IP network.
You find that write I/O's are making multiple round
trips between the host initiator and target array.
What do you do to fix the problem?
A. Write exchange
B. Reduce number of hops
C. Increase the host cache
D. Write acceleration
There are 12 Solaris hosts connected to two fabrics
and a DMX2000. All the hosts are dual-pathed using
Emulex HBAs. All 12 HBAs in each fabric are connected
and zoned to one FA port. Each host is doing 2000
IOPS. Each I/O size is 64KB. Two of the hosts are
receiving the following error in their /var/adm/messages
file: SCSI transport failed:
reason 'timeout': retrying command What do you advise
Abc .com to do?
A. Use Unix command sysdef queue_depth command to
increase the queue_depth
B. Reduce the queue depth of the HBAs reporting the
SCSI retry messages in /kernel/drv/lpfc.conf file
C. Reduce the queue depth of the HBA reporting the
SCSI retry messages in /kernel/drv/sd.conf file
D. Increase the queue depth of the HBAs reporting
the SCSI retry messages in /kernel/drv/lpfc.conf file
Which iSCSI discovery method requires the target's
IP address, TCP port, and iSCSI target name?
Abc .com wants to consolidate their current SAN consisting
of four fully populated ED-64M2s, two DS-32M2 switches
and two DS-32B2 switches. Current total throughput
is 80% of their aggregate bandwidth. Customer anticipates
70% increase in throughput over the next two years.
Abc .com wants ED-64M2. How many ED-64M2's are required
considering the future growth?
Customer has implemented HP-UX Campus Cluster using
dual-lock disks. They have experienced "split
brain" syndrome in the past. What is a permanent
fix for this problem?
A. Unlock cluster lock disks
B. Implement a single lock disk
C. Add one more node to both sides of the cluster
D. Implement multiple network and heartbeat configurations
for each node in the cluster
