I was recommended by one of my friend, he used the Lead2pass 300-320 dumps and said they are helpful. He was right! I passed my Cisco 300-320 exam yesterday. I was lucky, all my questions in the exams were from Lead2pass dumps. Following questions and answers are all new published by Cisco Official Exam Center: https://www.lead2pass.com/300-320.html QUESTION 301Which statement about vPC technology is true?

Return traffic is policy-based routed back to the SLB.Which SLB design has been implemented? A.    router modeB.    inline bridge modeC.    one-armed modeD.    two-armed mode Answer: D QUESTION 303Recently, the WAN links between the headquarters and branch offices have been slow under peak congestion, yet multiple alternate WAN paths exist that are not always congested. What technology can allow traffic to be routed in a more informed manner to utilize transport characteristics such as delay, loss, or link load? A.    performance routingB.    static routingC.    on demand routingD.    policy based routing Answer: A QUESTION 304Which two design principles should be followed to scale EIGRP properly? (Choose two.) A.    Ensure that the network design follows a structured hierarchical topology.B.    Utilize route summarization on edge devices.C.    Implement multiple autonomous systems, regardless of the size of the network.D.    Tune EIGRP delay metric on all core devices.E.    Configure offset lists on the network border. Answer: AB QUESTION 305An engineer is attempting to improve OSPF network performance and discovers that the entire SPT recomputes whenever a type 1 or type 2 LSA is received within an area.Which action can optimize SPT operations? A.    Tune LSA throttling thresholds.B.    Enable incremental SPF.C.    Configure totally stubby areas throughout the domain.D.    Summarize networks on all ABRs. Answer: BExplanation:https://www.cisco.com/c/en/us/td/docs/ios/12_0s/feature/guide/ospfispf.html#wp1027184Benefits of OSPF Incremental SPF OSPF uses Dijkstra's SPF algorithm to compute the shortest path tree (SPT). During the computation of the SPT, the shortest path to each node is discovered. The topology tree is used to populate the routing table with routes to IP networks. When changes to a Type-1 or Type-2 link-state advertisement (LSA) occur in an area, the entire SPT is recomputed. In many cases, the entire SPT need not be recomputed because most of the tree remains unchanged. Incremental SPF allows the system to recompute only theaffected part of the tree. Recomputing only a portion of the tree rather than the entire tree results in faster OSPF convergence and saves CPU resources. Note that if the change to a Type-1 or Type-2 LSA occurs in the calculating router itself, then the full SPT is performed.Incremental SPF is scheduled in the same way as the full SPF. Routers enabled with incremental SPF and routers not enabled with incremental SPF can function in the same internetwork.
