Question 13hardmultiple choice

A large enterprise has a campus network with a collapsed core design. The core switch connects to two distribution switches, each serving several access switches. The network uses OSPF as the IGP. Recently, after a link failure between the core and distribution switch A, the network experienced a 30-second outage before converging. The engineer wants to improve convergence time to under 5 seconds. The budget is limited, so hardware upgrades are not an option. The engineer is considering the following actions: A. Enable OSPF Fast Hello on all interfaces. B. Reduce OSPF dead timer to 1 second and hello timer to 333 milliseconds. C. Implement OSPF LSA throttling with a minimum interval of 0 ms. D. Use OSPF incremental SPF (iSPF).

Which action will provide the most significant improvement in convergence time for this scenario?

Question 14easymultiple choice

A small business has a single router connected to the internet and a switch for the LAN. They want to implement VLANs to separate guest and corporate traffic. The router has only one physical interface to the switch. The network engineer proposes using subinterfaces with 802.1Q trunking on the router interface. Which configuration step is required on the switch port connected to the router?

Question 21mediummultiple choice

A mid-size enterprise is deploying a new branch office with 50 users. The branch will have its own router, switch, and wireless AP. The WAN link is a 50 Mbps MPLS circuit. The company uses VoIP and requires Quality of Service. The network administrator has configured the router with a QoS policy that marks VoIP traffic with DSCP EF and all other traffic with DSCP 0. The policy also shapes traffic to 50 Mbps. After deployment, users report that voice quality is poor during peak hours. The administrator checks the router and sees that the output queue on the WAN interface is often full and drops are occurring. Which action should the administrator take to improve voice quality?
