If you've missed any of the Storage Smarts questions in our daily e-mails, here's another chance to test your memory. We've compiled questions 41 to 50 below. Good luck!

Question #41
SAN expert Chris Poelker recently listed his six-step prescription for SAN backup. Listed below are four of those steps but which one is NOT one of the six?
a. Consolidate your server environment using clustering for better availability with fewer servers
b. Incorporate all servers into the SAN
c. Use SAN based storage for file services if you can
d. For remote servers, if your network supports it, use iSCSI connections into the SAN to consolidate backup across the enterprise

Question #42
This is an Internet protocol-based storage networking technology developed by the Internet Engineering Task Force (IETF). Its mechanisms enable the transmission of Fibre Channel (FC) information by tunneling data between storage area network (SAN) facilities over IP networks; this capacity facilitates data sharing over a geographically distributed enterprise.
a. iSCSI
b. iFCP
c. FCIP
d. SCSI

Question #43
Your environment supports three different types of operating systems: Linux, Win2000 and Tru64. Can you use all three with SAN technology?
a. Yes
b. No
c. Only Linux and Win2000
d. Only Tru64
e. None of the above

Question #44
This is the primary organization for fostering the development of technology standards in the United States. It works with industry groups and long-established computer standards from this organization include the American Standard Code for Information Interchange (ASCII) and the Small Computer System Interface (SCSI).
a. ISO
b. BCBS
c. IBTA
d. ANSI
e. IEC
Click to see if you are correct.

Question #45
How can you tell the difference between SCSI and IDE hard drives?
a. Check the instruction manual
b. Ask the guy sitting next to you
c. Read the labels
d. There is no noticeable difference
e. Ask the vendor
Click to see if you are correct.

Question #46
This technology transmits data between computer devices at a data rate of 1 or 2 Gbps (and 10 Gbps in the near future). It is especially suited for connecting computer servers to shared storage devices and for interconnecting storage controllers and drives.
a. Fiber connectivity
b. Legacy cabling
c. High speed Internet
d. Fibre Channel
e. Fiber optic
Click to see if you are correct.

Question #47
SAN expert Chris Poelker pointed out the many benefits of moving towards a SAN strategy. Listed below are five benefits. Which one is NOT listed by Chris?
a. Increased disk utilization
b. Decreased workload
c. Improved DR capabilities
d. Improved overall availability
e. Support server clustering
Click to see if you are correct.

Question #48
This is a network -- typically a storage network -- that channels incoming data flow from any of multiple input ports to the output port. Used with multiple storage disk drives, it is said to be able to improve latency and to ensure "fairness."
a. Switch-on-a-chip
b. External storage
c. Fibre Channel
d. Salsa-on-a-chip
e. Direct-attached storage
Click to see if you are correct.

Question #49
This is a centralized repository for business information that provides common data management and protection, as well as data sharing functions, through connections to numerous computer systems.
a. File storage
b. Enterprise storage
c. Lock box
d. Block storage
e. Savings and Loan
Click to see if you are correct.

Question #50
SAN expert Christopher Poelker says that in general, there are a few basic areas where employing a SAN can reduce overall storage costs significantly. Which of the five choices listed below is NOT one them?
a. Availability
b. Storability
c. Management
d. Disk utilization
e. Backup
