Q41.

How did media-based protections work on floppy disks?

By creating special sectors in the distribution floppies

By checking for the presence of a hardware device

By requiring users to enter a serial number

By activating the software online

Discuss

Answer: (a).By creating special sectors in the distribution floppies Explanation:In floppy disks, this was implemented by creating special “bad” sectors in the distribution floppies and verifying that these sectors were present when the program was executed.

Q42.

Which programs could deal with the special sectors created in media-based protections?

Programs that required users to activate the software online

Programs that used a hardware device to secure the software

Programs that could duplicate the special sectors

Programs that used a serial number to authenticate software

Discuss

Answer: (c).Programs that could duplicate the special sectors Explanation:Several programs were written that could deal with these special sectors and actually try to duplicate them as well. Two popular ones were CopyWrite and Transcopy.

Q43.

Are programs that duplicate the special sectors in media-based protections legal?

Yes

May be Yes or No

Can't say

Discuss

Answer: (b).No Explanation:There was significant debate on whether these programs were legal or not. Nowadays they probably wouldn’t be considered legal.

Q44.

What is the purpose of using serial numbers in software?

To prevent the installation of software on unapproved hardware

To track the number of installations on a given machine

To ensure that the user has a valid copy of the software

To reduce the likelihood of unauthorized software modifications

Discuss

Answer: (c).To ensure that the user has a valid copy of the software Explanation:The purpose of using serial numbers in software is to ensure that the user has a valid copy of the software.

Q45.

How does the installation program verify the validity of a serial number?

It checks the user’s name and address against a database of authorized users

It uses a secret validation algorithm

It sends the serial number to the software vendor for verification

It compares the serial number to a list of known pirated keys

Discuss

Answer: (b).It uses a secret validation algorithm Explanation:The installation program verifies the validity of a serial number by using a secret validation algorithm.

Q46.

Why is relying exclusively on a plain serial number flawed?

It is too difficult for legitimate users to enter correctly

It is easily sharable among users

It does not provide enough information to the software vendor about the user

It is too expensive to produce and distribute serial numbers

Discuss

Answer: (b).It is easily sharable among users Explanation:Relying exclusively on a plain serial number is flawed because it is easily sharable among users.

Q47.

What is the impact of the internet on the effectiveness of serial numbers as a protection mechanism?

It has no impact

It has made serial numbers more effective

It has made serial numbers less effective

It has made serial numbers unnecessary

Discuss

Answer: (c).It has made serial numbers less effective Explanation:The impact of the internet on the effectiveness of serial numbers as a protection mechanism is that it has made them less effective because it is easy for malicious users to post valid serial numbers online.

Q48.

What is a challenge response in the context of software copy protection mechanisms?

A well-known authentication protocol used for authenticating specific users or computers in computer networks

A unique machine identifier used during installation to register a user with the software vendor

An encryption key known only to the user and software vendor

A response generated by the software vendor that is mathematically confirmed to be valid during installation

Discuss

Answer: (a).A well-known authentication protocol used for authenticating specific users or computers in computer networks Explanation:A challenge response is a well-known authentication protocol typically used for authenticating specific users or computers in computer networks. This protocol can be used in the context of software copy protection mechanisms.

Q49.

What is the difference between the original serial number protection scheme and the challenge response scheme?

The challenge response scheme retrieves a unique machine identifier during installation.

The original serial number scheme sends a challenge response to the software vendor.

The challenge response scheme does not require the user to type in a serial number during installation.

The original serial number scheme does not provide usage information to the software vendor.

Discuss

Answer: (a).The challenge response scheme retrieves a unique machine identifier during installation. Explanation:In the challenge response scheme, during installation, the installation program retrieves a unique machine identifier (such as the CPU ID), and generates a unique value from the combination of the serial number and the machine identifier. In the original serial number scheme, the installation program only requires the user to type in the serial number during installation.

Q50.

How does the challenge response scheme provide usage information to the software vendor?

By sending a response back to the installation program that is mathematically confirmed to be valid

By limiting the number of installations that the user is authorized to make

By retrieving a unique machine identifier during installation

By sending a unique value to the software vendor that is generated from the combination of the serial number and the machine identifier

Discuss

Answer: (d).By sending a unique value to the software vendor that is generated from the combination of the serial number and the machine identifier Explanation:In the challenge response scheme, during installation, the installation program retrieves a unique machine identifier (such as the CPU ID), and generates a unique value from the combination of the serial number and the machine identifier. This value is then sent to the software vendor, which provides usage information to the software vendor.
