Answer Interrupt refers to a software or hardware interrupt to a processor that causes the program to jump to another program to handle the interrupt request. Before leaving the program that was being executed at the time of the interrupt, the CPU must save the state of the computer so that the original program can continue after the interrupt has been serviced. *A physically constrained user interface is one in which a user's operations are limited by the physical characteristics of the interface device. An example would be a keypad with the choices limited to the operations permitted by each key. *View refers to database views, which restrict access to information contained in a database through content-dependent access control.

Explanation:
Two points are important to consider when it comes to ethical hacking: integrity and independence.
By not using an ethical hacking firm that hires or subcontracts to ex-hackers of others who have criminal records, an entire subset of risks can be avoided by an organization. Also, it is not cost-effective for a single firm to fund the effort of the ongoing research and development, systems development, and maintenance that is needed to operate state-of-the-art proprietary and open source testing tools and techniques.
External penetration firms are more effective than internal penetration testers because they are not influenced by any previous system security decisions, knowledge of the current system environment, or future system security plans. Moreover, an employee performing penetration testing might be reluctant to fully report security gaps.
Incorrect Answers:
A: External penetration service firms are more cost-effective than using corporate resources for penetration testing. This is a valid reason to use external penetration service firms.
B: External penetration service firms do offer a lack of corporate bias compared to corporate resources.
This is a valid reason to use external penetration service firms.
D: External penetration service firms do tend to ensure more complete reporting than corporate resources.
This is a valid reason to use external penetration service firms.
