Which statement compares traditional networks and controller-based networks?

• Only traditional networks natively support centralized management.

• Traditional and controller-based networks abstract policies from device configurations

Refer to the exhibit. Which route does R1 select for traffic that is destined to 192.168.16.2?

• 192.168.16.0/27

• 192.168.16.0/24

• 192.168.16.0/21

Which action does the router take as it forwards a packet through the network?

• The router replaces the source and destination labels with the sending router interface label as a source and the next hop router label as a destination.

• The router replaces the original source and destination MAC addresses with the sending router MAC address as the source and neighbor MAC address as the

  destination.

• The router encapsulates the original packet and then includes a tag that identifies the source router MAC address and transmit transparently to the destination.

• The router encapsulates the source and destination IP addresses with the sending router P address as the source and the neighbor IP address as the

  destination.

Which function is performed by DHCP snooping?

• rate-limits certain traffic

• propagates VLAN information between switches

• listens to multicast traffic for packet forwarding

• provides DDoS mitigation

What are two benefits of using the PortFast feature? (Choose two)

• Enabled interfaces come up and move to the forwarding state immediately.

• Enabled interfaces wait 50 seconds before they move to the forwarding stat

• Enabled interfaces never generate topology change notifications.

• Enabled interfaces are automatically placed in listening state.

• Enabled interfaces that move to the learning state generate switch topology change notifications.
