Demo Questions

Question 1

Which statement accurately describes the configuration requirements for disjoint Layer 2 networks on Cisco UCS?

  • A: The Cisco UCS Fabric Interconnect must be in switch mode.
  • B: The VLAN IDs must overlap in both Layer 2 domains.
  • C: All of the uplinks must be in one port channel to keep all of the ports active.
  • D: The Cisco UCS Fabric Interconnect must be in end-host mode.

Correct Answer: D

Question 2

Which component is required to run FCoE?

  • A: converged network adapter
  • B: iSCSI gateway
  • C: host bus adapter
  • D: Fibre Channel adapter

Correct Answer: A

Computers can connect to FCoE with converged network adapters (CNAs), which contain both Fibre Channel host bus adapter (HBA) and Ethernet Network Interface Card (NIC) functionality on the same adapter card. CNAs have one or more physical Ethernet ports. FCoE encapsulation can be done in software with a conventional Ethernet network interface card, however FCoE CNAs offload (from the CPU) the low level frame processing and SCSI protocol functions traditionally performed by Fibre Channel host bus adapters.




Question 3

Which component of a Cisco Nexus 1000V Series switch is responsible for propagating configurations to virtual switches?

  • A: SUP
  • B: FEX
  • C: VSM
  • D: VEM

Correct Answer: D

Product Architecture  
The Cisco Nexus 1000V Series Switch has two major components (Figure 1): the virtual Ethernet module (VEM), which runs inside the hypervisor, and the virtual supervisor module (VSM), which manages the VEMs. 
Virtual Supervisor Module  
The Cisco Nexus 1000V Series VSM controls multiple VEMs as one logical modular distributed virtual switch. Configuration is performed through the VSM and is automatically propagated to the VEMs.

Question 4

Which two characteristics are associated with the access layer of a Data Center Unified Fabric network? (Choose two.)

  • A: voice, data, and wireless convergence
  • B: no packet manipulation
  • C: QoS-policing
  • D: routing manipulation and filtering
  • E: QoS – classification and queueing

Correct Answer: AE




Question 5

Which technology provides additional scalability and simplification of an Ethernet network, providing more efficient forwarding and eliminating the need for the STP?

  • A: vPC
  • B: PVST+
  • C: FabricPath
  • D: OTV

Correct Answer: C




Question 6

Which two actions must be performed when you configure Cisco VN-Link in hardware? (Choose two.)

  • A: Create a port profile and profile clients in Cisco UCS Manager.
  • B: Create a distributed virtual switch under the datacenter folder in VMware vCenter.
  • C: Create a standard switch on an ESXi host and map the network adapters to the switch.
  • D: Create a distributed virtual switch in Cisco UCS Manager.
  • E: Add an ESX host to the distributed virtual switch in Cisco UCS Manager.

Correct Answer: AD




Question 7

You plan to configure LISP between two data centers. Which two LISP components must be configured? (Choose two.)

  • A: VTEP
  • B: the site identifier
  • C: a map resolver
  • D: a map server
  • E: VNI

Correct Answer: CD




Question 8

Which two terms relate to the capability of a physical NIC to present virtual NICs to the operating system or hypervisor? (Choose two.)

  • A: VM-FEX
  • B: NIV
  • C: NPIV
  • D: NIC teaming
  • E: Adapter-FEX

Correct Answer: BE




Question 9

You have a Cisco UCS Fabric Interconnect that connects to upstream switches via four 10-Gbps port channels. You have a fully populated Cisco UCS B-Series Blade Server chassis that has a UCS-IOM-2208XP installed and uses all of the ports for the blade servers. What is the oversubscription ratio between the chassis and the upstream switch?

  • A: 6:1
  • B: 3:1
  • C: 2:1
  • D: 4:1

Correct Answer: B




Question 10

Which two options are advantages of the core-edge SAN topology as compared to the collapsed-core SAN topology? (Choose two.)

  • A: predictable performance
  • B: minimized ISL usage
  • C: easier to analyze and tune performance
  • D: single management interface
  • E: higher scalability

Correct Answer: AE
