    D. Only the vpxuser can access the host remotely via the DCUI but not vCLI, VMA and vSphere PowerCLI
    • B, D
    • Lockdown Mode restricts access to a host to the vpxuser via the DCUI or vCenter server only. The vCLI, VMA, and vSphere PowerCLI are all blocked from direct access.
  45. You've enabled lockdown mode, which of the following services are available at the host?
    A. View and change any service
    B. View and change some service, but not others
    C. View some services, but not others
    D. View any services, but changes cannot be made.
    A. Lockdown Mode has no effect on the services that are available to those who can access the host.
    (this multiple choice question has been scrambled)
  46. How do you enable Lockdown Mode?
    • From vCenter:
    • 1. Host and Clusters view
    • 2. Click your host
    • 3. Open the Configuration tab and choose Security Profile 
    • 4. Scroll past firewall setting and click Edit next to lockdown mode

  48. What is the default setting for Promiscuous Mode?
    Reject
  49. What is the effect of MAC Address Change policy and what is the default?
    Default is "Accept."  When set to "reject" the switch will not allow incoming packets to flow to the new effective MAC address.
  50. What is the effect of Forged Transmits and what is the default?
    Default is "Accept". When set to reject, the switch checks to see whether the MAC addresses on the outbound packets are the MAC addresses assigned to the VMs, if not the switch discards the traffic.
  51. Why are some security policies set to "Accept" by default when they reject would be more secure?
    MAC Address Changes and Forget transmits are both "Accept" by default in order to accomodate PSV or Microsoft Cluster Server Nework Load Balancing in Unicast mode.
