• Question 75:

  Which two items are services that are provided by Cisco Fabric Services? (Choose two.)

  A. device alias distribution
  B. VLAN database distribution
  C. Kerberos proxy distribution
  D. RSA key pair distribution
  E. DPVM configuration distribution
  A. device alias distribution
  E. DPVM configuration distribution

  ---

  The device alias application uses the Cisco Fabric Services (CFS) infrastructure to enable efficient database management and distribution. Device aliases use the coordinated distribution mode and the fabric-wide distribution scope. DPVM

  can use CFS to distribute the database to all switches in the fabric. This allows devices to move anywhere and keep the same VSAN membership. You should enable CFS distribution on all switches in the fabric. Using the CFS infrastructure,

  each DPVM server learns the DPVM database from each of its neighboring switches during the ISL bring-up process. If you change the database locally, the DPVM server notifies its neighboring switches, and that database is updated by all

  switches in the fabric.
