Cisco 642-997 Online Questions & Answers

• Question 81:

  Which three selections represent implementations of Cisco VN-Link technology? (Choose three.)

  A. Cisco Nexus 1000V
  B. Cisco Nexus 2000 FEX
  C. Cisco VM-FEX
  D. VMware PTS
  E. vMotion
  A. Cisco Nexus 1000V
  C. Cisco VM-FEX
  D. VMware PTS

  ---

  The VM is powered on and resides on the ESX Host 1 with all the information stored on the shared storage.

  The VM was connected to the PODy (where y is the number of your POD) PTS VDS by associating it to port group VLAN61 that was created on the Cisco Nexus 5548 device. The VM has been connected to the vPC system automatically

  using a VN-Link in the hardware in PTS mode or in VM-FEX mode.

  The VEM bits are used in PTS mode to connect the VM VNIC to the VMNIC interface.

  In this case, the VMNIC interface is not a real VMNIC but a dynamic VNIC that is presented as an interface to the ESX OS. The dynamic VNIC is enabled when the Cisco UCS VIC creates and configures the VNIC parameters inherited from

  port group VLAN61.

• Question 82:

  Which two Cisco Nexus platforms support Adapter FEX? (Choose two.)

  A. Cisco Nexus 7000 Series Switches
  B. Cisco Nexus 5000 Series Switches
  C. Cisco Nexus 5500 Series Switches
  D. Cisco Nexus 4000 Series Switches
  E. Cisco Nexus 2000 Series Fabric Extenders
  C. Cisco Nexus 5500 Series Switches
  E. Cisco Nexus 2000 Series Fabric Extenders

  At the access layer, the Adapter-FEX requires a FEX-enabled adapter on a server that connects to a parent device that supports virtualization of interfaces. The Adapter-FEX is supported on the following platforms:

  The Cisco Unified Computing System (UCS) platform supports Adapter-FEX between UCS

  servers and the UCS Fabric Interconnect.

  ?

  The Adapter-FEX is supported on the Cisco Nexus 5500 Series platform and on the Cisco Nexus 2200 Fabric Extender that is connected to a Cisco Nexus 5500 Series parent device. This implementation works on a variety of FEX-capable

  adapters, including the Cisco UCS P81E virtual interface card (VIC) adapter for the UCS C-Series platform and third party adapters such as the Broadcom BCM57712 Convergence Network Interface Card, that implement the virtual network

  tag (VNTag) technology.

  A. EHV
  B. vPC
  C. Cisco FabricPath
  D. Cisco OTV
  E. VN-Tag
  A. EHV

  ---

  EHV is the feature that enables NIV.

  A. cleartext
  B. DES-SHA1
  C. DES-CBC3-SHA
  D. Cisco Type 7
  E. RC4-SHA
  F. 3DES
  A. cleartext
  D. Cisco Type 7
  F. 3DES

• Question 88:

  Refer to the exhibit.

  

  Which two outcomes occur when the state is Other? (Choose two.)

  A. The VSAN on each end of the connection does not match.
  B. The interface is not an E Port.
  C. The interface is not an F Port.
  D. The interface is administratively shut down.
  E. Cisco Fabric Services is not enabled.
  F. NPIV should be disabled.
  G. The interface is functioning, but may have errors.
  H. Encryption is not enabled.
  C. The interface is not an F Port.
  D. The interface is administratively shut down.

• Question 89:

  Which two functions are enabled when you set up vPC+ at the FabricPath edge? (Choose two.)

  A. the ability to attach Cisco Fabric Extenders in FEX active/active mode
  B. the ability to stop all Layer 3 egress traffic
  C. the ability to attach servers to edge switches with port-channel teaming
  D. the ability to attach additional Classic Ethernet switches in vPC+ mode
  A. the ability to attach Cisco Fabric Extenders in FEX active/active mode
  C. the ability to attach servers to edge switches with port-channel teaming

• Question 90:

  Which two types of traffic are carried over a vPC peer link when no failure scenarios are present? (Choose two.)

  A. multicast data traffic
  B. unicast data traffic
  C. broadcast data traffic
  D. vPC keep-alive messages
  A. multicast data traffic
  C. broadcast data traffic

  ---

  The vPC peer link is the link used to synchronize states between the vPC peer devices. The vPC peer link carries control traffic between two vPC switches and also multicast, broadcast data traffic. In some link failure scenarios, it also carries unicast traffic. You should have at least two 10 Gigabit Ethernet interfaces for peer links.
