Exam A
Your customer is relocating its data center to a new building. The new data center is two miles from the existing data center. The customer’s scheduled maintenance window is too short to accommodate a flash cut, so it plans on relocating 25 percent of the servers on separate weekends. The customer does not wish to change the IP addresses of the servers and is trying to find a way to bridge its subnets between the two data centers during the migration period. Which Cisco product may be able to accomplish this?
A. SFS 3000
B. Aironet 1120
C. Aironet 1400
D. Cisco IP Transfer Point

Correct Answer: B
In a Cisco Catalyst 6500-E Series chassis, why is a special type of fan used?
A. Nonredundant power mode generates less heat, and consequently a slower fan speed can be used.
B. It provides additional cooling, which is required by new line cards that generate more heat due to increased power consumption.
C. A dual-speed fan is required to support the redundant and nonredundant power-mode features of the Catalyst 6500-E Series.
D. A larger fan is required to provide increased airflow because the Catalyst 6500-E Series has a smaller form factor; there isn’t more heat, there is less room.

Correct Answer: AB
Your retail customer has 330 branch locations that it wishes to connect via Frame Relay. At the headquarters location there will be two DS-3 Frame Relay circuits, each connected to an ISR 3845 router. Each branch location will have a fractional T1 with a 128-kbps CIR and a PVC mapped to each of the DS-3 circuits. Which two considerations must be addressed for this design? (Choose two.)
A. The MTU for the Frame Relay circuits should be set to 4470 to allow the LMI message to include all 330 DLCIs.
B. Additional routers and circuits should be installed at headquarters so that no more than 200 branch locations are mapped to each ISR due to IDB limitations.
C. The customer should not run OSPF. Since all branches are connected to the same circuit at headquarters they must be in the same OSPF area, and the number of branches exceeds the design recommendations for routers in an OSPF area.
D. Frame Relay traffic shaping should be implemented to prevent congestion in the Frame Relay switch.
E. The CIRs should be reduced so the DS-3 circuits are not oversubscribed.
