Cisco 640-864 Online Questions & Answers

• Question 21:

  DRAG DROP

  Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and is logically separate from the other segments.

  Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independent routing paths.

  Here are some examples of network virtualization technologies:

  VLAN: Virtual local-area network

  VSAN: Virtual storage-area network

  VRF. Virtual routing and forwarding

  VPN: Virtual private network

  vPC. Virtual Port Channel

  Device virtualization allows for a single physical device to act like multiple copies of itself. Device virtualization enables many logical devices to run independently of each other on the same physical piece of hardware. The software creates

  virtual hardware that can function just like the physical network device. Another form of device virtualization entails using multiple physical devices to act as one logical unit.

  Here are some examples of device virtualization technologies:

  Server virtualization: Virtual machines (VM)

  Cisco Application Control Engine (ACE) context

  Virtual Switching System (VSS)

  Cisco Adaptive Security Appliance (ASA) firewall context

  Virtual device contexts (VDC)

• Question 25:

  By default, how does EIGRP's metric differ from OSPF?

  A. hops
  B. cost
  C. bandwidth
  D. delay
  D. delay

• Question 26:

  Which WLC interface is dedicated for WLAN client data?

  A. virtual interface
  B. dynamic interface
  C. management interface
  D. AP manager interface
  E. service port interface
  B. dynamic interface

  ---

  WLC Interface Types

  A WLC has five interface types:

  Management interface (static, configured at setup, mandatory) is used for in-band management, connectivity to AAA, and Layer 2 discovery and association. Service-port interface (static, configured at setup, optional) is used for out-of-band

  management. It is an optional interface that is statically configured. AP manager interface (static, configured at setup, mandatory except for 5508 WLC) is used for Layer 3 discovery and association. It has the source IP address of the AP that

  is statically configured.

  Dynamic interface (dynamic) is analogous to VLANs and is designated for WLAN client data. Virtual interface (static, configured at setup, mandatory) is used for leaver 3 security authentication, DHCP relay support, and mobility management.

• Question 27:

  An enterprise campus module is typically made up of four sub modules, as described by the Cisco Enterprise Architecture Model. Which two sub modules are part of this module?

  A. DMZ
  B. enterprise branch
  C. building distribution
  D. server farm/data center
  E. MAN
  C. building distribution
  D. server farm/data center

• Question 28:

  Which three technologies are recommended to be used for WAN connectivity in today's Enterprise Edge designs? (Choose three.)

  A. DWDM
  B. Metro Ethernet
  C. Frame Relay
  D. MPLS VPN
  E. ISDN
  F. DSL
  G. Wireless
  A. DWDM
  B. Metro Ethernet
  D. MPLS VPN

  ---

  There is some discussion about whether ISDN not DWDM should be the answer but it does say TODAYS network

• Question 29:

  A hierarchical design of the EIGRP domain facilitates which two of the following? (Choose two.)

  A. route summarization
  B. faster convergence
  C. unequal cost load balancing
  D. redistribution
  E. virtual links
  A. route summarization
  B. faster convergence

• Question 30:

  During which phase of the PPDIOO model would you conduct interviews with supporting staff to develop and propose a viable solution?

  A. Prepare
  B. Plan
  C. Design
  D. Implement
  E. Operate
  F. Optimize
  A. Prepare

  ---

  

  Prepare Phase The Prepare phase establishes organization and business requirements, develops a network strategy, and proposes a high-level conceptual architecture to support the strategy. Technologies that support the architecture are identified. This phase creates a business case to establish a financial justification for a network strategy.
