    VCAP-DCA Practice questions

    Krenztor Enthusiast
    Visibility: Open to anyone

      I've been studying for the VCAP-DCA on and off for a few months now and because of the nature of this being a hands on exam I haven't found a whole lot of practice quizzes to help get me ready for the test.  I decided to write my own list of questions instead.  The questions might not be well worded because I didn't have this idea of creating my own questions from the get go so some of them are just notes that I converted to questions.  Anyways, I hope this helps.  I haven't taken the test yet to not sure how much these questions relate to it but I've pulled from a lot of resources related to VCAP studying and stuck closely to the Blueprint.  If anyone sees any incorrect answers let me know

          >380. How do you add a custom driver using Image Builder in PowerCLI?  Image name is ESXi-5.5.zip, driver package is Driver1.zip, and new ISO should be ESXi-5.5-Install.iso

          The questions would look more like:

          An environment includes several hosts using Auto-Deploy.  A new driver has shipped that the server vendor recommends for performance and stability.

          Create a new image that incorporates the driver.


          Software Directory: c:\Autodeploy on the ControlCenter server

          Image name: ESXi-5.5.zip

          Driver package: Driver1.zip

          New ISO: ESXi-5.5-Install.iso

          Do not overwrite the existing ISO.

          Do not use the new ISO to deploy hosts at this time.

          Note: Deploying hosts or changing the existing rules may end your exam prematurely.
