  Explanation Explanation/Reference:2, 4, and 8 Gb Fibre Channel all use 8b/10b encoding. Meaning, 8 bits of data gets encoded into 10 bits of transmitted information ?the two bits are used for data integrity. Well, if the link is 8Gb, how much do we actually get to use for data ? given that 2 out of every 10 bits aren't "user" data? FC link speeds are somewhat of an anomaly, given that they're actually faster than the stated link speed would suggest. Original 1Gb FC is actually 1.0625Gb/s, and each generation has kept this standard and multiplied it. 8Gb FC would be 8?.0625, or actual bandwidth of 8.5Gb/s. 8.5*.80 = 6.8. 6.8Gb of usable bandwidth on an 8Gb FC link. 10GE (and 10G FC, for that matter) uses 64b/66b encoding. For every 64 bits of data, only 2 bits are used for integrity checks. While theoretically this lowers the overall protection of the data, and increases the amount of data discarded in case of failure, that actual number of data units that are discarded due to failing serialization/deserialization is minuscule. For a 10Gb link using 64b/66b encoding, that leaves 96.96% of the bandwidth for user data, or 9.7Gb/s. https://www.iol.unh.edu/sites/default/files/knowledgebase/10gec/10GbE_Cl49.pdf

  D. ISCSI between the servers and the ToR switches that passes the FCoE traffic to the MDS switches
  B. FCoE between the servers and the ToR switches that passes the Ffcee Channel traffic to the MDS switches

• Question 84:

  A customer requires a tool to manage Cisco network hardware. The solution must use secure communication using a secure network protocol, support the use of declarative language to manage the state of resources, and periodically pull changes to the controlled nodes.

  Which tool meets these requirements?

  A. Ansible

• Question 85:

  A Cisco engineer is preparing a service profile template for a design, which consists of 20 x UCS B200M6 blade servers 2 x UCS 6454 Fabric Interconnect in End Host Mode, and 3 x UCS 5108 server chassis with 2408 Fabric Extenders The blade servers are equipped with VIC 1480 adapters The engineer does not configure a vNIC/vHBA placement policy in the service profile and the vNICs and vHBAs are assigned to the vCon in a particular order What is the mapping scheme in which Cisco UCS assigns the vCons based on the type of server and the selected virtual slot?

  A. linear ordered
  B. network mesh
  C. cross match
  D. round robin
  D. round robin

• Question 86:

  An engineer finishes the initial set up of a VXLAN EVPN network. The engineer is asked to plan for connectivity that supports redundancy and extends multiple virtual routing and forwarding domains.

• Question 87:

  A engineer wants to eliminate the manual process of checking the system hardware and firmware against a specified hardware compatibility tool. The tool must be able to manage an extensive list of devices including cisco HyperFlex, MDS, and Nexus switches.
