NO.1 A UPK content author has a single-user installation of UPK 3.6.1 on his or her computer.The author
would like to keep this installation on his or her machine, but also wants to Install the single user of UPK
11.0.
Identify the process that enables this.
A.The content author needs to create an .odarc file of all the content he or she wants to keep from the
3.6.1 single-user Installation, and then uninstall 3.6.1.After 3.6.1 is uninstalled, the author can install
11.0.Two different versions of UPK single user cannot be installed on one computer at the same time.
B.The content author can run the UPK 11.0 setup and install UPK 11.0 in a folder structure that is different
from where the UPK 3.6.1 is installed.Both versions of the developer can be launched independently.
C.The content author can run the UPK 11.0 setup and Install UPK 11.0 in the same folder structure as the
3.6.1 Installation.This will upgrade the 3.6.1 installation to version 11.0.Two different versions of UPK
single user cannot be installed on one computer at the same time.
D.The content author can run the UPK 11.0 setup and install UPK 11.0 in the same folder structure as the
3.6.1 installation.Because the cache locations of 11.0 and 3.6.1 are different, the two versions of the UPK
can be launched independently.

The UPK Developer does not correctly recognize objects and action areas while recording a target
application.The author provides you with a sample topic to review.You notice that the target application
appears in a VMware Player virtual machine window in the screenshots.The action areas cover the entire
virtual machine window, and the objects in the target application cannot be recognized.
How can you fix this problem?

a virtualization software.
B.The author should maximize the VMware Player window during recording so that the UPK Developer
can recognize the objects in the application.
C.The UPK Developer should be installed in the virtual machine, and the target application should be
recorded inside the virtual machine.

NO.4 UPK Developer requires Microsoft .NET Framework 3.5.Some of the machines in the organization
where Developer will be installed already have .NET Framework 3.5 installed, but most do
not.Organizational policy dictates that ALL of the machines where Developer will be installed DO NOT
have access to the internet for security reasons.The UPK installer comes packaged with a "bootstrap"
installer for .NET Framework 3.5, which connects to the Internet to install .NET Framework 3.5 from there.
Identify the method that would ensure that UPK Developer is installed securely with its .NET Framework
3.5 requirement.
A.Temporarily allow all machines access to the Internet during the duration of the distribution of the
installation, so that the "bootstrap" installer can connect properly.
B.Embed the full .NET Framework 3.5 installer package within the UPK installer, allowing the UPK
installer to use that package Instead of "bootstrap."
C.Ensure force installation of .NET Framework 3.5 on ALL machines before the installation of UPK
Developer.
D.Install only to the machines with .NET Framework 3.5 already installed; delay installation on other
machines until they have been updated with .NET Framework 3.5.

running in the same Citrix session.
*(E)Sound output will likely be choppy.
