Q75. In order to meet your service level agreement, your network designer created a design solution that includes interface dampening. In which two ways will interface dampening benefit your overall network design? (Choose two.) 

A. Interface dampening uses an exponential backoff algorithm to suppress event reporting to the upper-level protocols. 

B. When the interface is dampened, further link events are not reported to the upper protocol modules. 

C. When the interface is dampened, further link events are reported to the upper protocol module. 

D. Periodic interface flapping that affects the routing system as a whole should have a period shorter than the system convergence time. 

Answer: AB

Q79. In an OSPF network, users in a particular OSPF non-backbone area are complaining about slow access speeds to a shared corporate resource in another OSPF area. Traceroutes show that theusers are taking a suboptimal default route to the destinations. Which solution will improve access speed? 

A. Make the area totally stubby so that the default can be followed along the best path. 

B. Create a virtual link between the areas so that traffic can shortcut directly between them. 

C. Implement policy routing to channel the traffic in the optimal direction. 

D. Leak specific summaries on the ABRs for the remote subnets in addition to the default.
