Sometimes SDN leverages various overlay networking technologies to create layer(s) of network abstraction. What describes an overlay network?

• A.It transmits packets that traverse over network devices like switches and routers
• B.It encapsulates packets at source and destination, which incurs additional overhead
• C.It is responsible for the delivery of packets; NAT- or VRF-based segregation is required
• D.Packet delivery and reliability occurs at Layer 3 and Layer 4

• B.IP packets with identical source and destination IP addresses
• C.IP packet with the multicast IP destination address

This network is running legacy STP 802.1d. Assuming "hello_timer" is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

• A.The transit_delay=5 and bpdu_delay=20 are recommended values, considering hello_timer=2 and specified.
• B.Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in
  802.1d to speed up STP convergence process.
• C.The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
• D.Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
