Q1. Cisco VM-FEX technology extends Cisco Fabric Extender technology to the virtual machine that eliminates which one of the following?

A.The dedicated interface on the parent switch is eliminated.

B.The software-based switch in the hypervisor is eliminated.

C.All virtual machine traffic is eliminated.

D.The need for a physical switch is eliminated.

Answer: B

Q2. Which Cisco Nexus product operates inside the VMware ESX hypervisor, and supports the Cisco VM-FEX server virtualization technology?

A.1010

B.2000

C.5500

D.7000

Answer: A

Q3. Which four statements about Cisco Overlay Transport Virtualization are true? (Choose four.)

A.OTV is a "MAC in IP" technique for supporting Layer 2 VLANs over any transport.

B.OTV is not a public standard, even though the technology is based on standardized protocols.

C.OTV is public standard because the technology is based on standardized protocols.

D.OTV is supported on all M-Series modules of Cisco Nexus 7000.

E.OTV is core and site transparent. Changes to the Layer 2 design of the sites are needed.

F.OTV enables the network administrator to statically map MAC addresses to IP addresses.

G.OTV cannot support multiple concurrent overlays.

H.OTV supports Catalyst 6500.

Answer: ABDF

Q4. What is a typical output of the design planning phase that characterizes an existing data center?

A.a high-level conceptual architecture proposal

B.a gap analysis

C.a verification plan

D.reactive fault detection and correction

Answer: B

Q5. Given the requirements, which Cisco Nexus product is Cisco recommended?

A rich feature set that makes it well suited to top-of-rack, middle-of-row, or end-of-row access-layer applications.

Data center racks with standards-based 1 and 10 Gigabit Ethernet and FCoE features, and virtual machine awareness features that allow IT departments to consolidate networks.

A combination of high port density, lossless Ethernet, wire-speed performance, and extremely low latency that makes the switch family well suited to meet the growing demand for 10 Gigabit Ethernet.

A.1000v

B.1010

C.2000

D.3000

E.4000

F.5500

Answer: F

Q6. Which is a feature of the Data Center Core layer?

A.The core layer provides the high-speed packet switching backplane for all flows going in and out of the data center.

B.The core layer provides the high-speed packet switching backplane for all flows going out of the data center.

C.The core layer is purely a Layer 2 environment. As a result, the core layer is not free of spanning tree and vPC.

D.The core layer provides connectivity to multiple aggregation modules and provides a resilient Layer 3 routed fabric with a single point of failure.

Answer: A

Q7. In a medium size Data Center, which three routing protocols would you use? (Choose Three.)

A.EIGRP

B.ISIS

C.OSPF

D.RIPv2

E.HSRP

Answer: ABC

A.Layer 3 data center core

B.Layer 3 data center core with Layer 2 extension

C.Layer 2 data center core

D.Layer 2 data center core with Layer 3 extension

Answer: A

Q9. Which two options are business requirements that drive the data center design? (Choose two.)

A.Increase virtual machine-to-host ratio.

B.Reduce power consumption.

C.Reduce latency within the network.

D.Migrate to FCoE.

E.Reduce operation expenditure.

F.Increase network throughput.

Answer: BE
