  A. full mesh
  B. peer-to-peer
  C. partial mesh
  D. hub and spoke

• Question 8:

  In which NAS operating mode are ACL filtering and bandwidth throttling only provided during posture assessment?

  A. Layer 2
  B. Layer 3
  C. in-band
  D. out-of-band
  E. edge
  F. central
  D. out-of-band

  ---

  explanation:

  https://www.safaribooksonline.com/library/view/foundation-learning-guide/9780132652933/ch06.html "In out-of-band traffic flow, the Cisco NAS is in the traffic path only during the posture assessment. Out-of-band mode provides VLAN port-based and role-based access control. ACL filtering and bandwidth throttling are provided only during posture assessment."

• Question 9:

  Which two of these correctly describe Fibre Channel? (Choose two.)

  A. supports multiple protocols
  B. works only in a shared or loop environment
  C. allows addressing for up to 4 million nodes
  D. allows addressing for up to 8 million nodes
  E. provides a high speed transport for SCSI payloads
  F. may stretch to a distance of up to 100 km before needing extenders
  A. supports multiple protocols
  E. provides a high speed transport for SCSI payloads

  ---

  explanation:

  Fibre Channel includes these features: Addressing for up to 16 million nodes Loop (shared) and fabric (switched) transport options Host speeds of 100 to 400 MBps, or an effective throughput of 1 to 4 Gbps on the fabric Segment distances of up to 6 miles (10 km) Support for multiple protocol https://www.safaribooksonline.com/library/view/foundation-learning-guide/9780132652933/ch06.html

  A. to provide service internetworking
  B. to support transparency for Layer 2 frames
  C. as a connection identifier to indicate destination
  D. as a mapping to the DLCI in service internetworking
  E. to provide a trunk by which all VLANs can navigate from one site to one or multiple sites
  C. as a connection identifier to indicate destination
