You need to create a trust relationship between your company and a vendor. You need to
implement the system so that it will allow users from the vendor's organization to access your
accounts payable system using the accounts created for them by the vendor. What type of

permission to roles and then the administrator would simply adjust the role of the user when he
or she changes jobs
Which of the following authenticators is appropriate to use by itself rather than in combination
with other biometric factors?
A. Voice pattern recognition
B. Hand geometry
C. Palm scans
, D. Heart/pulse patterns - answer- C. Palm scans compare the vein patterns in the palm to a
database to authenticate a user.
As part of hiring a new employee, Sven's identity management team creates a new user object
and ensures that the user object is available in the directories and systems where it is needed.
What is this process called? - answer- Provisioning includes the creation, maintenance, and
removal of user objects from applications, systems, and directories.

implement an access control system that allows administrators to set access rights but does not
allow the delegation of those rights to other users. What is the best type of access control

Steve is the risk manager for a company on the east coast of the United States. He recently
undertook a replacement cost analysis and determined that rebuilding and reconfiguring the
data center would cost $20 million. Steve consulted with hurricane experts, data center
specialists, and structural engineers and they determined that a typical CAT 3 hurricane that
successfully hits the east coast would cause approximately $5 million in damages. The
meteorologists determined that Steve's facility lies in an area where they are likely to experience
a CAT 3 hurricane once every 10 years.
Based upon the information in this scenario, what is the exposure factor for the effect of a CAT 3
hurricane on Steve's data center? - answer- The exposure factor is the percentage of the
facility that risk managers expect will be damaged if a risk materializes. It is calculated by
