EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the links to R4.

When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?

R1 has no route to R2 and drops the traffic

R1 load-balances across the paths through R3 and R4 to reach R2

R1 forwards the traffic to R3, but R3 drops the traffic

R1 forwards the traffic to R3 in order to reach R2

11. A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup.

Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

Use EIGRP to establish a neighbor relationship with the main office via L3VPN MPLS and the IPSEC VPN tunnel.

Use BGP with the multipath feature enabled to force traffic via the primary path when available.

12. Refer to the exhibit.

Which solution decreases the EIGRP convergence time?

Enable sub second timers

Increase the hold time value

Increase the dead timer value

Enable stub routing on the spokes

to emulate LAN segments to transport Layer 2 frames over a Layer 3 network

to establish physical connectivity between switches and routers

to provide virtualization by encapsulating network traffic over IP tunnels

14. An engineer must design a solution to provide backup connectivity between two sites. The engineer plans to use an Internet connection but company policy requires the connection to be encrypted. Additionally, there are several applications that utilize multicast to deliver video streams between the sites.

17. Which design consideration must be made when using IPv6 overlay tunnels?

Overlay tunnels that connect isolated IPv6 networks can be considered a final IPv6 network architecture.

Overlay tunnels should only be considered as a transition technique toward a permanent solution.

Overlay tunnels can be configured only between border devices and require only the IPv6 protocol stack.

Overlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.
