0100.0ccc.cccd (with a PVID = to the VLAN) QUESTION NO: 94 Refer to the exhibit.All switches have default bridge priorities, and originate BPDUs with MAC addresses as indicated.The numbers shown are STP link metrics.After STP converges, you discover that traffic from switch SWG toward switch SWD takes a lessoptimal path. What can you do to optimize the STP tree in this switched network? Cisco 400-101 Exam "Pass Any Exam. Any Time." - 75

A. Change the priority of switch SWA to a lower value than the default value. B. Change the priority of switch SWB to a higher value than the default value. C. Change the priority of switch SWG to a higher value than the default value. D. Change the priority of switch SWD to a lower value than the default value. Answer: DExplanation: In this topology, we see that all port paths and priorities are the same, so the lowest MAC addresswill be used to determine the best STP path. From SWG, SWE will be chosen as the next switch inthe path because it has a lower MAC address than SWF. From SWE, traffic will go to SWCbecause it has a lower MAC address, and then to SWD, instead of going from SWE directly toSWD. If we lower the priority of SWD (lower means better with STP) then traffic will be sentdirectly to SWD. Answer: D,E,FExplanation: VSS operates on a unified control plane with a distributed forwarding architecture in which theactive supervisor (or switch) is responsible for actively participating with the rest of the networkand for managing and maintaining control plane information. VSS actually removes the need for a next-hop redundancy protocol like HSRP or VRRP. Thesefirst-hop redundancy protocols are usually heavily tied to a fast-converging routing protocol likeEIGRP, and still require that each device maintain it’s own control plane. The standby chassis monitors the active chassis using the VSL. If it detects failure, the standby QUESTION NO: 95 Which three statements are true about VSS? (Choose three.) A. VSS separates the control planes of the active and the standby chassis. B. Configuration changes can be made on both active and standby chassis. C. When the VSS active chassis recovers after a failure, it initiates a switchover and takes on the active role again. D. VSS unifies the control planes of the active and the standby chassis. E. HSRP configuration is not required to run VSS. F. The VSS standby chassis monitors the VSS active chassis using the VSL.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
