Demo Questions

Question 1

You must use one logical uplink for Fibre Channel traffic and Ethernet traffic on a Cisco UCS system. Which type of port should you use to accomplish this task?

  • A: FCoE storage
  • B: server
  • C: FCoE uplink
  • D: uplink

Correct Answer: C

Server and Uplink Ports on the Fabric Interconnect  
Each fabric interconnect has a set of ports in a fixed port module that you can configure as either server ports or uplink Ethernet ports. These ports are not reserved. They cannot be used by a Cisco UCS instance until you configure them. You can add expansion modules to increase the number of uplink ports on the fabric interconnect or to add uplink Fibre Channel ports to the fabric interconnect.   
You need to create LAN pin groups and SAN pin groups to pin traffic from servers to an uplink port. 
Each fabric interconnect can include the following types of ports:  
Server Ports 
Server ports handle data traffic between the fabric interconnect and the adapter cards on the servers. You can only configure server ports on the fixed port module. Expansion modules do not include server ports. 
Uplink Ethernet Ports 
Uplink Ethernet ports handle Ethernet traffic between the fabric interconnect and the next layer of the network. All network-bound Ethernet traffic is pinned to one of these ports. By default, Ethernet ports are unconfigured. However, you can configure them to function in the following ways:  
✑ Server 
✑ 
Uplink 
✑ FCoE 
✑ Appliance 
You can configure uplink Ethernet ports on either the fixed module or an expansion module.  
Uplink Fibre Channel Ports 
Uplink Fibre Channel ports handle FCoE traffic between the fabric interconnect and the next layer of the network. All network-bound FCoE traffic is pinned to one of these ports.  By default, Fibre Channel ports are uplink. However, you can configure them to function as Fibre Channel storage ports. This is useful in cases where a Cisco UCS requires a connection to a Direct-Attached Storage (DAS) device.  
You can only configure uplink Fibre Channel ports on an expansion module. The fixed module does not include uplink Fibre Channel ports.

Question 2

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 3

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 4

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 5

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 6

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 7

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 8

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 9

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 10

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
