Your network has a mixture of Fast Ethernet and Gigabit Ethernet links. What needs t o be done to ensure optimal data routing when using OSPF?()

A. Nothing. OSPF will determine the most optimal path for routing data by default.
B. Adjust the hello and dead timers for more rapid detection of link failures.
C. Increase the reference - bandw idth used to calculate the interface default metrics, on all routers in your network.
D. Set the priority values on every broadcast interface to ensure that the designated and backup designated routers are the routers with the most processor and memory  resources.

OSPF is enabled on router A. You execute the following command on router A and receive theaccompanying output:RouterA#ping 224.0.0.5 repeat1Type escape sequence to abort.Sending 1, 1 00 - byte ICMP Echos to 224.0.0.5, timeout is 2 seconds:Reply to request 0 from 10.100.100.1, 4 ms10.100.100.1 is the IP address of a loopback interface on router A.
What can you conclude about router A?()

A. Only the router A loopback interface is parti cipating in the OSPF routing process
B. None of the router A interfaces are participating in the OSPF routing process
C. Router A is using the loopback interface IP address as its OSPF router ID

Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to be functioning properly. What can you conclude from the exhibit and the show running - configuration command output? ()

A. The OSPF areas are not configured correctly.
B. The wildcard masks for the 10.x .x.x networks are incorrect.
C. The 172.16.x.x networks need to be connected to area 0 using virtual links.
D. The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to 172.16.0.0/16 and data is being "black holed."
E. There  is not enough information to make a determination.
