    SY0-501 Part 03 Q08 011

    Which of the following should be the NEXT step to determine if there is an unauthorized user on the network?

    • Apply MAC filtering and see if the router drops any of the systems.
    • Physically check each of the authorized systems to determine if they are logged onto the network.
    • Deny the “unknown” host because the hostname is not known and MAC filtering is not applied to this host.
    • Conduct a ping sweep of each of the authorized systems and see if an echo response is received.
  9. When performing data acquisition on a workstation, which of the following should be captured based on memory volatility? (Choose two.)
