    Answer the following questions, and then refer to Appendix A, “Answers to Review Questions,” for the answers.

    1.What are characteristics of Fibre Channel? (Choose three.)

    1. Parallel standard

    2. Full duplex

    3. Half duplex

    4. Addresses more than 16 million nodes

    5. Segment lengths of up to 6 miles (10 km)

    6. Bus lengths of up to 75 feet (25 meters)

    2.What technology allows multiple logical SANs to exist in the same physical fabric?

    1. FICON

    2. IVR

    3. Zoning

    4. VSAN

    5. SANTap

    3.What is a means of restricting visibility and connectivity between devices connected to a common Fibre Channel SAN or VSAN?

    1. IVR

    2. FICON

    3. Zoning

    4. SANTap

    5. VSAN

    4.What are the characteristics of a large-scale SAN design? (Choose two.)

    1. Uses a collapsed core to support much larger port densities than the core-edge design FICON

    2. Uses a core-edge design to support much larger port densities than the collapsed-core design

    3. Has a lower port-density efficiency as compared to small- or medium-scale designs

    4. Has the highest port-density efficiency as compared to small- or medium-scale designs

    5. Uses oversubscribed interconnectivity on the ISLs

    6. Does not use ISLs

    5.What can be a factor in SAN design? (Choose three.)

    1. Port density and topology

    2. Fast convergence and stability

    3. Fast routing protocol reservations

    4. Fault isolation using VSAN

    5. Simplified SAN management through storage captivity

    6. Network-attached file service

    6.Which three are benefits of a unified fabric?

    1. Reduced cabling

    2. Improved network performance

    3. Reduced bandwidth requirements

    4. Fewer network adapters per server

    5. Power and cooling savings

    6. IP-enabled storage

    7.Which of these types of adapters is used by a server when deploying FCoE? (Choose two.)

    1. HBA

    2. Ethernet NIC

    3. CNA

    4. HBA and Ethernet NIC

    5. HBA and CNA

    6. CNA and Ethernet NIC

    8.Which three are best-practice guidelines for unified fabric design?

    1. If you enable MST, you should ensure that the MST instance for the FCoE VLANs is the same as the instance for the data VLANs.

    2. If you enable MST, you should use a separate MST instance for FCoE VLANs.

    3. Use separate FCoE VLANs for SAN A and SAN B in dual-fabric SAN designs.

    4. Use identical FCoE VLANs for SAN A and SAN B in dual-fabric SAN designs.

    5. When using FCoE on the Cisco Nexus 2000 FEXs, these FEXs should be connected straight through.

    6. When using FCoE on the Cisco Nexus 2000 FEXs, these FEXs should be connected as active/active extenders.

    9.Which are DCB standards? (Choose three.)

    1. 802.1Qbb PFC

    2. 802.1w STP

    3. 802,1Qau Congestion Notification

    4. 802.1Qaz ETS

    5. 802.1F SAN over MAN
