Worked practice questions

Which drawback attaches to a virtual private network?

  1. It cannot be used by employees who travel
  2. It requires a leased line for every remote user
  3. It exposes all traffic in unencrypted form
  4. Its performance depends on factors outside the firm
Show answer and solution

Correct answer: D. Its performance depends on factors outside the firm

1. A virtual private network saves on telecommunications costs and on networking equipment. 2. On the downside, its availability and performance, especially over the internet, depend on factors largely outside the control of the organization. 3. Travelling salespeople and telecommuters are among its main beneficiaries, so the first option is false. 4. It exists precisely to avoid leasing expensive private lines. 5. Data are encrypted once tunnelled, which defeats an interceptor. 6. The genuine weakness is therefore dependence on a public network the firm does not run. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 13 "Using Technology to Manage Information", section 13.2 Private Lines: Virtual Private Networks_

Show answer and solution

Correct answer: C. Operational, tactical, and strategic levels

1. Companies typically have several types of information system. 2. Each type serves a particular level of decision-making. 3. Those levels are operational, tactical, and strategic. 4.

What do management support systems allow users to do?

  1. Record every sale as the transaction occurs
  2. Print payslips for the whole workforce monthly
  3. Back up the database to an off-site location
  4. Analyse data to forecast and model strategies
Show answer and solution

Correct answer: D. Analyse data to forecast and model strategies

1. Management support systems are dynamic systems built for analysis rather than record keeping. 2. They allow users to analyse data to make forecasts, identify business trends, and model business strategies. 3. Recording sales as they happen is the work of the transaction processing system. 4. Payroll printing and backups are routine processing tasks rather than management support. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 13 "Using Technology to Manage Information", section 13.3 Management Information Systems_
