QUESTION 164
You are a technician at Certkiller.com. Your newly appointed Certkiller trainee wants to know which device will act as a bridge between a Fiber Channel SAN and an IP network.
What would your reply be?
A. Storage Router
B. Switching hub
C. FC-HBA attached host
D. FC Switch
E. NAS GE Switch
Correct Answer: A Section: (none) Explanation
Explanation/Reference: Explanation:
The Cisco storage router delivers redundant iSCSI paths to a pair of Fibre Channel switches. iSCSI takes advantage of the connection-oriented TCP protocol for reliable service. Ethernet was already part of the IT network. This meant trained personnel were on board, and simplified
the storage networking installation shown in the figure.
Cost was an important factor in choosing iSCSI. Because the research facility already had TCP/IP and
Gigabit Ethernet networks installed, the iSCSI solution fit their budget and met their storage networking
needs.

QUESTION 165
You are the network administrator at Certkiller. Your newly appointed Certkiller trainee wants to know which protocol encapsulates Fiber Channel frames so that they can be transported transparently over an IP network.
What will your reply be?
A. iSCSO
B. FCIP
C. SCSI-FP
D. eSCSI
E. CIFS
Correct Answer: B Section: (none) Explanation
Explanation/Reference: Explanation:
An important technology for linking Fibre Channel SANs is FCIP. FCIP and iSCSI are complementary solutions for enabling company-wide access to storage. FCIP transparently interconnects Fibre Channel SAN islands over IP networks through FCIP tunnels, while iSCSI allows IP-connected hosts to access iSCSI or FC-connected storage.

Which storage networking model would you include your network upgrade design?
A. Metro Optical
B. NAS
C. SAN
D. Universal IP
Correct Answer: C Section: (none) Explanation
QUESTION 167
Which IP storage network solution is best suited for high-volume, write-intensive, transaction-driven applications?
A. Storage area networking
B. Network-attached storage
C. Local storage
D. Metro optical storage
Correct Answer: A Section: (none) Explanation
Explanation/Reference:Explanation:
SAN provides block-oriented access to native disk storage. It is based on a shared or switched
infrastructure, often Fibre Channel. You can extend SAN to an ip infrastructure.
New protocols and products are emerging that allow the integration of SANs with the IP network.
Historically, SANs have been well suited to high-volume, write-intensive transaction-driven applications.
Reference: Arch student guide p.13-7.
QUESTION 168
In which scenario would a SAN storage solution be a better choice than an iSCSI-based NAS solution?
A. Traditional file-sharing applications.
B. Fast growing data storage needs.
C. Applications that cannot tolerate block level, storage access latency.
D. Highly reads-intensive applications.
E. Web serving applications with many active pages.
Correct Answer: C Section: (none) Explanation
QUESTION 169
What are disadvantages to storage directly attached to the application servers? (Choose three)
A. Reliability
B. Scalability
C. Redundancy
D. Manageability
E. Available bandwidth
F. Access speed
Correct Answer: ABD Section: (none) Explanation
Explanation/Reference: Explanation:
B: System administrators are faced with the challenging task to managing storage and making it scalable to accommodate future needs. With storage directly attached to the server, scalability is difficult. The storage expansion capability is limited to the capacity of the server (for example, as measured by the number of I/O controllers and devices per controller configured is the server). The nature of the small computer system (SCSI) bus commonly used to connect commodity disks to a commodity server makes it difficult to allocate more disk storage without interrupting and rebooting the server, and thus affecting applications.
C: No redundancy is provided
Incorrect answers:
A: Reliability would be good. **CONTRADICTING ANSWER!!**
E: Bandwidth would be excellent.
F: Access speed would be excellent.
Reference: Arch student guide p.13-6.
QUESTION 170
Which protocol enables the location of a fully synchronized hot backup Fiber Channel storage solution at a remote site over existing optical WAN links?
A. iSCSI
B. SCSI-FCP
C. FCIP
D. HSRP
Correct Answer: C Section: (none) Explanation
Explanation/Reference: Explanation:
You can use FCIP to connect two geographically dispersed Fibre Channel storage arrays for the purpose of synchronous data storage. If the local storage array becomes unavailable, an application could utilize the FCIP link to access the data on the “hot backup” storage system at the remote site. It is also possible to implement remote tape backups to further protect customers’ valuable information in the event of disaster at the primary site.
