  Summary address blocks can be used to support several network applications:

  Separate VLANs for voice and data, and even role-based addressing Bit splitting for route summarization Addressing for virtual private network (VPN) clients Network Address Translation (NAT)

• Question 655:

  Which three options are basic technical metrics that a good SLA includes? (Choose three.)

  A. packet loss
  B. devices
  C. latency
  D. clients
  E. IP availability
  F. distance

• Question 656:

  What are two benefits of migrating from a vPC design to FabricPath? (Choose two.)

  A. infrastructure scalability
  B. lower latency
  C. ease of configuration
  D. network stability
  E. easy to manage
  A. infrastructure scalability

• Question 657:

  What are the two methods of ensuring that the RPF check passes? (Choose two.)

  A. implementing static mroutes
  B. implementing OSPF routing protocol
  C. implementing MBGP
  D. disabling the interface of the router back to the multicast source
  E. disabling BGP routing protocol
  A. implementing static mroutes
  C. implementing MBGP

  RPF is checking does the multicast traffic comes from shortest path, due to avoid loop. It checks it according to routing table and underlying IGP. So if it is needed to send traffic between subnets you can use static routes or OSPF as underlying protocol.

• Question 658:

  How does stub routing affect transit routes in EIGRP?

  A. Transit routes are passed from a stub network to a hub network.
  B. It is designed to prevent the distribution of external routes.
  C. It prevents the hub router from advertising networks learned from the spokes.
  D. Transit routes are filtered from stub networks to the network hub.
  C. It prevents the hub router from advertising networks learned from the spokes.

• Question 659:

  A. VSS
  B. VLAN
  C. VRF-Lite
  D. MEC
  C. VRF-Lite

• Question 660:

  Which STP feature allows an access port to bypass the learning and listening?

  A. Port Fast
  B. BPDU Guard
  C. BPDU Filter
  D. UplinkFast
  A. Port Fast
