Question 1

A retailer pays a specialist firm to look for weaknesses in its own systems. There is a written agreement beforehand setting out what may be tested and when. What makes this legitimate, and what does the retailer get out of it?

Accepted Answer

It is legitimate because the owner of the systems gave permission in advance and the limits were agreed in writing; what the retailer gets is a report saying what was found and what to fix, in order of importance.

Answer

It is legitimate because the intention is to help, which is what the law looks at rather than whether permission was given.

Answer

It is legitimate only if nothing is found, since a test that uncovers a weakness has caused the very harm it was meant to prevent.

Answer

It is legitimate because the firm doing the work is qualified, which is what separates this from unauthorised access.

Question 2

A marketing agency collects extensive personal data from its users, including information it does not need, and keeps this data for over ten years. Which data protection principles are being violated?

Accepted Answer

The principles of data minimisation and storage limitation.

Answer

The principles of data sharing and public transparency.

Answer

The principles of data encryption and hardware security.

Answer

The principles of data accuracy and user consent.

Question 3

A software house offers two products. One is supplied with its source code, under a licence letting anybody read it, change it and pass on their changed version. The other arrives as a finished program only, under a licence forbidding copying it or taking it apart. What are the two arrangements called, and what may a user do with each?

Accepted Answer

The first is open source and the second is proprietary: a user of the first may read the code, change it and pass the changed version on under the licence's terms, while a user of the second may only run the program as supplied. Note that a proprietary program can still cost nothing to download, since price and licence are separate questions.

Answer

The first is freeware and the second is shareware, and what separates them is what each one costs.

Answer

The first is open source and the second proprietary, and the difference is that open source software is always free of charge while proprietary software always has to be paid for.

Answer

Both are proprietary, since somebody wrote each of them and therefore owns it; all that differs is how much of the code they chose to publish.

Question 4

A large office replaces all its functional computers every two years to ensure they have the latest models. Beyond the financial cost, what are the primary environmental impacts of this policy?

Answer

The increase in electricity usage during the manufacturing process only.

Answer

The loss of data during the transition between old and new machines.

Answer

The environmental costs associated with manufacturing new devices and disposing of old ones.

Answer

The reduction in the amount of software updates required for the new machines.

Question 5

A government service is moved entirely online, but some citizens cannot access it because they lack a reliable internet connection or a suitable device. What is this issue called and how should it be addressed?

Answer

The digital divide, which should be addressed by forcing users to buy better equipment.

Answer

The digital divide, which should be addressed by designing services to be accessible to all users.

Answer

The connectivity gap, which should be addressed by limiting the service to those with high-speed internet.

Answer

The hardware deficit, which should be addressed by providing free computers to every citizen.
