A. Increase the number of SSIDs to load-balance the client traffic.
B. Choose a high minimum data rate to reduce the duty cycle.
C. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.
D. Enable 802.11ag channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
E. Use directional antennas to achieve better sector separation channel reuse.
F. Implement a four-channel design on 2.4 GHz to increase the number of available channels.
Answer: BCE
Q8. Refer to the exhibit.
A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane. How will they adjust the design to reduce the flooding of update packets?
A. Change the area type of the links to be level-1-2 to allow level-1 updates.
B. Change the network type of the links from broadcast to point-to-point.
C. Use IS-IS mesh groups.
D. Configure SPF timers to be more aggressive so that updates are more quickly cleared from the queue.
Answer: C
Q9. What are two benefits of using BFD for failure detection in the design of a network?
(Choose two.)
A. BFD can provide failure detection in less than one second.
B. BFD can be used as a generic and consistent failure detection mechanism for EIGRP, IS-IS, and OSPF.
C. BFD eliminates router protocol hello notification.
D. BFD can be used for all types of network interfaces.
E. BFD is independent of the network protocol.
Answer: AB
Q10. Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity to all locations in both networks. How is this accomplished without creating routing loops?
A. Use route maps on the ASBRs to allow only internal routes to be redistributed.
B. Use route maps on the ASBRs to allow internal and external routes to be redistributed.
C. Use route maps on the ASBRs to set tags for redistributed routes.
D. Use route maps on the ASBRs to filter routes with tags so they are not redistributed.
Answer: D
Q11. What is the definition of the ITIL framework?
A. an ISO framework that establishes a model for network management and contains guidelines for managing objects, the management database, and the application entity
