• Question 255:

  Which mechanism is enabled by default in the OTV technology to conserve bandwidth?

  A. Automatic unicast flooding is suppressed over the OTV link.
  B. BPDUs are allowed to traverse the OTV link.
  C. Control plane traffic is prevented from traversing the OTV link.
  D. Data plane traffic is prevented from traversing the OTV link.
  A. Automatic unicast flooding is suppressed over the OTV link.

• Question 256:

  An engineer has been asked to purpose a solution for a campus network that offers the capability to create multiple Layer 3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding. The proposed design must be scalable to support a high number of virtual networks allowing simple configuration and management with minimal administrative overhead.

  Which technology does the engineer recommend?

  A. hop-by-hop VRF-Lite
  B. multihop IPsec tunneling
  C. multihop MPLS core
  D. hop-by-hop easy virtual network
  D. hop-by-hop easy virtual network

• Question 257:

  Which statement about Fibre Channel communications is correct?

  A. N_Port to N_Port connections use logical node connection points.
  B. Flow control is only provided by QoS.
  C. It must be implemented in an arbitrated loop.
  D. Communication methods are similar to those of an Ethernet bus.
  A. N_Port to N_Port connections use logical node connection points.

  ---

  Fibre Channel supports a logical node connection point between node ports (N_ports). This is similar to TCP and UDP sockets.

• Question 258:

  An engineer wants to have a resilient access layer in data center so that switches on the access layer have separate physical connections to a pair of redundant distribution switches. Which technology achieves this goals?

  A. PaGP
  B. LACP
  C. VSL
  D. EVPC
  E. VSS
  F. ECMP
  E. VSS

• Question 259:

  A network engineer is implementing virtualization into the enterprise network. Which system should be used to address policy enforcement at the distribution layer?

  A. Cisco IOS based firewall
  B. multilayer switches
  C. integrated firewall services
  D. identity services engine
  E. intrusion protection systems
  C. integrated firewall services

• Question 260:

  DRAG DROP An engineer must provide segmentation for a shop floor environment that has only a single /24 network available. Each area of machinery needs to have its own subnet. Drag and drop the subnet from the left onto the corresponding IP addressing design on the right. Not all options are used.
