Refer to the exhibit. R2 has two paths to reach 192.168.13.0/24, but traffic is sent only through R3.
Which action allows traffic to use both paths?
Configure the variance 4 command under the EIGRP process on R2.
Configure the bandwidth 2000 command under interface FastEthernet0/0 on R2.
Configure the delay 1 command under interface FastEthernet0/0 on R2.
Configure the variance 2 command under the EIGRP process on R2.

Refer to the exhibits. Phase-3 tunnels cannot be established between spoke-to-spoke in DMVPN.
Which two commands are missing? (Choose two.)
The ip nhrp redirect command is missing on the spoke routers.
The ip nhrp shortcut command is missing on the spoke routers.
The ip nhrp redirect command is missing on the hub router.
The ip nhrp shortcut command is missing on the hub router.

Refer to the exhibit. The network administrator configured redistribution on an ASBR to reach to all WAN networks but failed.
Which action resolves the issue?
The route map EIGRP->OSPF must have the 10.0.106.0/24 entry to exist in one of the three prefix lists to pass
EIGRP must redistribute the 10.0.106.0/24 route instead of using the network statement
The OSPF process must have a metric when redistributing prefixes from EIGRP
The route map must have the keyword prefix-list to evaluate the prefix list entries
