Advanced SAN Architecture
Questions, Answers, Braindumps (HP0-438)
every body , feeling free to clear my paper and sending
some questions from my paper which were exactly the
same ones which i got from www.examcheets.com.
Which are two of the most important considerations
when deciding to expand a fabric? Select TWO.
A. maintain the original fabric topology
B. maintain the original data access needs
C. expand the fabric for maximum bandwidth
D. expand the fabric for maximum connectivity
E. expand the fabric so that it supports future growth
Answer: B, E
Before merging a fabric in a high-available redundant
SAN environment with B-Series switches, you change
conflicting zoning configurations and domain IDs.
What else must you do in case of a mismatch to avoid
A. Adjust the name table entries for one switch at
B. Adjust the buffer-to-buffer credits settings in
one fabric at a time.
C. Adjust the Core PID parameter bit settings in one
fabric at a time.
D. Adjust the TCP/IP subnet address settings for one
switch at a time.
What is the consequence of merging a zoned fabric
with a non-zoned fabric?
A. The fabrics do not merge. They segment and require
B. Devices that were in the non-zoned fabric are not
accessible until they are added to the currently enabled
C. Devices in the fabric are not accessible until
the devices in the non-zoned fabric are zoned and
made part of the effective configuration.
D. Any devices that were in the non-zoned fabric are
automatically configured into a new zone as part of
the effective configuration so they can function.
A SAN administrator has an existing test SAN based
on 1 Gbps B-series SAN switches with zoning. To evaluate
the compatibility of 1 Gbps and 2 Gbps switches, the
administrator powers on a 1 Gbps and a 2 Gbps SAN
switch (factory default settings without zoning).
An ISL is then installed between the two switches.
The administrator notices that the fabric segments.
What are two possible causes of the segmentation?
A. The zoning information is incompatible.
B. The core PID parameters are conflicting.
C. The new switch has a conflicting domain ID.
D. The two switches are not at the same firmware version.
E. The speed on the port must first be set for 1 Gbps
Answer: B, C
Which two factors affect the merging of SANs? Select
A. IP addresses
B. SNMP configuration
C. zone naming standards
D. switch fabric parameters
E. switch naming standards
Answer: C, D
A SAN consists of two cascaded switches with no free
ports and one ISL. The SAN administrator intends to
add a new switch and cascade it off one of the existing
switches. What is the recommended procedure?
A. Shut down the SAN and recable it with the new switch.
B. Use the ISL to connect the two existing switches
to the new switch.
C. Shut down one of the existing switches and recable
with the new switch.
D. Attach the new switch to the least critical device
port and recable the SAN.
What is required to consolidate two fabrics with B-Series
switches in a Meta SAN with some common storage? Select
A. MP Router
B. fabric merge
C. proxy devices
D. proxy switches
E. unique domain IDs
Answer: A, C
Which PID formats use the same PIDs for a port?
A. native and core
B. VC encoded and native
C. core and extended edge
D. native and extended edge
What is a typical consequence when you migrate a cascaded
to a meshed fabric?
A. average hop count increases
B. number of user ports decreases
C. ISL latency affects data throughput
D. number of device paths does not change
Why is it important to secure the WWNs in the storage
A. to disable WWN spoofing attacks from FCAs
B. to allow safe promiscuous mode on FC ports
C. to prevent FC ports from entering promiscuous mode
D. to harden the name service in the fabric for security
