B. highest world wide name
C. assigned priority
D. lowest Domain ID
Q2. What should the administrator verify before connecting a stand-alone populated switch to an existing fabric?
A. Verify port type assignment
B. Verify domain ID assignment
C. Verify FC_ID port assignment
D. Verify principle switch assignment
Q3. What must you do to implement boot from a Fibre Channel SAN in your server infrastructure?
A. Configure the SAN Boot setting on the Fibre Channel HBA.
B. Enable direct disk access on the SAN switch.
C. Enable the BIOS on the Fibre Channel HBA.
D. Perform a loopback data test on the Fibre Channel HBA.
Q4. You are about to allocate storage to a host that includes adding new paths, devices, and zones to the configuration. What must be done prior to making any changes to the configuration? (Choose two.)
A. create new zones
B. activate change tracking
C. activate the new zone set
D. backup the configuration
E. copy the active zone set
Q5. The fabric security has been compromised and an unauthorized administrative session is established, removing zones from the active zone set. Which two (2) countermeasures should you take to reduce this risk? (Choose two.)
A. redirect logging to syslog of a protected system
B. enable port authentication using DH-CHAP
C. enable access control list and role based access control
D. disable Telnet and enable secure shell
E. enable storage access controls and link encryption
Q6. Users are complaining the response times are out of range on a retail application. Performance monitoring of the storage subsystem indicates that there are no problems. A check of the host error logs shows that there are excessive SCSI re-transmit errors. The 2Gb/s HBA on the host was recently replaced with a 4Gb/s HBA. What is the most probable cause of the timeout errors?
A. the link is utilizing 9 micron fiber
B. SCSI timeout value is set too small
C. the switch port to the storage subsystem is set at 2Gb/s
D. the distance from the host to the storage subsystem is greater than 175 meters

A. ISL aggregation
B. throughput requirement
C. location of principal switch
D. acceptable latency to the application
E. disk subsystem RAID level compatibility

B. Virtual Fabric
Q9. You are diagnosing a performance problem with a Fibre Channel attached server that is configured to run multipathing with dynamic I/O load balancing. You are not seeing the expected performance. You have determined that the server configuration is correct and that the fabric paths are not congested. What could be a possible cause for the lower than expected performance?
A. storage ports are configured to run half duplex
B. storage architecture is cache centric
C. storage ports are configured to run full duplex
D. storage architecture is controller centric
Q10. What is the primary reason for making an adjustment to the queue depth?
A. number of LUNs presented to the HBA changes
B. average size of I/O blocks going through the HBA changes
C. read/write ratio of I/O going through the HBA changesread/write ratio of I/O? going through the HBA changes
D. size of cache on the storage system changes
