QUESTION NO: 31
You are troubleshooting an OSPF problem where external routes are not showing up in the OSPF database. Which two options are valid checks that should be performed first to verify proper OSPF operation? (Choose two.)
A. Are the ASBRs trying to redistribute the external routes into a totally stubby area?
B. Are the ABRs configured with stubby areas?
C. Is the subnets keyword being used with the redistribution command?
D. Is backbone area (area 0) contiguous?
E. Is the CPU utilization of the routers high?
QUESTION NO: 32
When an OSPF design is planned, which implementation can help a router not have memory resource issues? Select the best response.
A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinations.
B. Have a backbone area (area 0) with 4 routers and 30,000 external routes injected into OSPF.
C. Have less OSPF areas to reduce the need for interarea route summarizations.
D. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2.
QUESTION NO: 33
The administrator wants to verify the current state of the OSPF database loading process. Which show command should the administrator use? Select the best response.
A. show ip ospf [process-id] interface
B. show ip ospf neighbor
C. show ip ospf [process-id]
D. show ip ospf [process-id area-id] database
QUESTION NO: 34
During a recent OSPF election among three routers, RTA was elected the DR and RTB was elected the BDR, as seen in the graphic. Assume that RTA fails, and that RTB takes the place of the DR while RTC becomes the new BDR. What will happen when RTA comes back online?
A. A new election will take place establishing an all new DR and BDR based on configured priority levels and MAC addresses.
B. RTA will take the place of DR immediately upon establishing its adjacencies.
C. RTA will take the place of DR only if RTB fails.
D. RTA will take the place of DR only if both RTB and RTC fail.
If a router with a higher priority value gets added to the network, it does not preempt the DR and BDR. The only time a DR and BDR changes is if one of them is out of service. If the DR is out of service, the BDR becomes the DR, and a new BDR is selected. If the BDR is out of service, a new BDR is elected. In a multi-access network, the router that is powered on first will generally become the DR, since the DR/BDR process is not pre-emptive.
