Refer to the exhibit. A network designer is testing a prototype of WAN connections. All of the routers in the exhibit are configured for OSPF routing. The design requires that the path between routers A and D through ISP-A is the primary and the path through ISP-B servers as a backup. The designer notices that router A has two equal-cost paths to the LAN on router D. How can the designer correct this problem?
Issue a clock rate 2000000 interface command on S0/0/1 of router ISP-B.
Change the default OSPF reference bandwidth on router A.
Configure two static routes with administrative distances of 10.
Use the bandwidth command to change the default bandwidth on the link to router B.

11.3.2 Modifying the Cost of the Link
46
Refer to the exhibit. R1 and R2 are unable to establish an adjacency. What two configuration changes will correct the problem? (Choose two.)
Set a lower priority on R2.
Configure the routers in the same area.
Set a lower cost on R2 compared to R1.
Add a backup designated router to the network.
Match the hello and dead timers on both routers.
Observable Description Max Value
1 correctness of response Option 2 and Option 5 are correct.
1 point for each correct option.
0 points if more options are selected than required. 2

11.2.5 Verifying OSPF
47 All routers in a network are configured in a single OSPF area with the same priority value. No loopback interface has been set on any of the routers. Which secondary value will the routers use to determine the router ID?
The highest MAC address among the active interfaces of the network will be used.
There will be no router ID until a loopback interface is configured.
The highest IP address among the active FastEthernet interfaces that are running OSPF will be used.
The highest IP address among the active interfaces will be used.
Observable Description Max Value
1 correctness of response 2 points for Option 4
0 points for any other option 2

router A
router B
router C
router D
both A and D
