  • 2. 

    Which one of the following describes how a portable or removable device can be protected from theft when NOT in use?

    • A.

      A. By activating a firewall.

    • B.

      B. By installing anti-virus software.

    • C.

      C. By locking it in a drawer.

    • D.

      D. By storing documents in a folder.

    Correct Answer
    C. C. By locking it in a drawer.
    Explanation
    The best way to protect a portable or removable device from theft when it is not in use is by physically securing it. Locking it in a drawer provides a physical barrier and prevents unauthorized access to the device. Activating a firewall and installing anti-virus software are measures to protect the device from online threats, but they do not prevent physical theft. Storing documents in a folder may provide some level of organization, but it does not protect the device itself from being stolen.

    Rate this question:

  • 3. 

    Which one of the following is MOST likely to happen if a network is unsecured?

    • A.

      A. Information will be accessible to others.

    • B.

      B. Information will be only be available during office hours.

      D. Forward it.

    Correct Answer
    A. A. Delete it.
    Explanation
    If you receive a chain letter email, the best course of action is to delete it. Chain letters are typically considered spam and can potentially contain harmful attachments or links. Replying to or forwarding the email can perpetuate the chain letter, causing it to spread to more people. Downloading any attachments from the email can also put your computer at risk for viruses or malware. Therefore, the safest and most appropriate response is to delete the chain letter email.

      D. The Firewall settings will be turned down.

    Correct Answer
    A. A. Any files saved only on the hard disk of the computer will be lost.
    Explanation
    Proximity to a heat source can cause a computer to malfunction, potentially leading to hardware failure. In such cases, files saved only on the hard disk of the computer may be lost if the malfunction affects the integrity of the storage device. Heat can damage the physical components of the hard disk, leading to data loss. Options B, C, and D are incorrect because they do not directly relate to the consequences of a computer malfunction due to proximity to a heat source.

    Correct Answer
    B. B. An Internet connection filter.
    Explanation
    A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and an untrusted external network, such as the internet. By examining the data packets, a firewall can block or allow traffic based on various criteria, such as IP addresses, port numbers, and protocols. It helps to prevent unauthorized access to a network and protects against malicious attacks, making B. An Internet connection filter the correct description for a firewall.

By marking these emails as junk, they are automatically filtered into a separate folder, reducing the risk of accidentally opening a malicious program. This practice is a common security measure to protect against malware and other harmful programs that can be spread through email attachments.

    Rate this question:

  • 20. 

    Which one of the following describes how confidential information should be sent using an unsecured network?

    • A.

      A. In a text only file.

    • B.

      B. In an encrypted format.

    • B.

      B. The checks listed in an help forum.

    • C.

      C. The checks listed in the device manual.

    • D.

      D. The checks sugguested by a colleague.

    Correct Answer
    A. A. The checks listed in the organisation’s security policy.
    Explanation
    The correct answer is A because an organization's security policy outlines the specific security measures and checks that should be followed when using any device, whether it is part of the organization's IT infrastructure or not. This policy ensures that consistent security practices are followed to protect the organization's data and systems from potential threats. Help forums, device manuals, or suggestions from colleagues may provide some guidance, but they may not be tailored to the organization's specific security requirements. Therefore, relying on the organization's security policy is the most appropriate approach.

    Which one of the following is an example of phishing?

    • A.

      A. An email containing a trojan via a file attachment.

    • B.

      B. An email asking you to forward it on to ten people in your address book.

    • C.

      C. An email directing the recipient to a website to verify credit card details.

    • D.

      D. An email warning the recipient of a computer virus threat.

    Correct Answer

    Explanation
    Phishing is a type of cyber attack where the attacker poses as a legitimate entity in order to deceive the recipient into revealing sensitive information such as passwords or credit card details. Option C fits this definition as it involves an email directing the recipient to a website to verify credit card details, which is a common tactic used by phishers to steal personal information. Options A, B, and D do not involve the deception of the recipient for personal gain, making them incorrect choices for examples of phishing.

    Rate this question:

  • 25. 

    Which one of the following describes how confidential information should be sent using an unsecured network?

    • A.

      A. Compressed using a data compression tool.

      D. Encrypted, so that only a person with a key can decrypt it.

    Correct Answer
    D. D. Encrypted, so that only a person with a key can decrypt it.
    Explanation
    Confidential information should be sent using encryption on an unsecured network to ensure that it remains secure and cannot be accessed by unauthorized individuals. Encryption involves converting the information into a coded form that can only be decrypted by someone who has the correct key. This ensures that even if the information is intercepted during transmission, it cannot be understood or accessed without the key. This is a crucial measure to protect sensitive data and maintain confidentiality.

    Rate this question:

  • 30. 

    Which one of the following would be considered the BEST way to remember a password?

    • A.

      A. Enter in in your mobile phone.

    • B.

      B. Write it down on a piece of paper.

    • C.

      C. Tell your work colleague.

    • D.

    Explanation
    The recommended action to prevent the risk of access to a network by outside users is to adjust the Internet security settings. This means configuring the settings to ensure that only authorized users can access the network and that proper security measures are in place to protect against unauthorized access. Swapping network cables in a hub cabinet, complaining to the system administrator, or hiding the computer under the desk would not effectively address the risk of outside users accessing the network.

      D. The device will be stolen.

    Correct Answer
    D. D. The device will be stolen.
    Explanation
    Leaving a mobile phone unattended on a desk increases the risk of theft. Unattended phones are easy targets for thieves who can quickly grab the device and disappear. The other options are less likely to happen in this scenario. The battery leaking is unlikely unless there is a defect in the phone or it is exposed to extreme conditions. The phone's memory being erased or causing mobile interference on a landline are also unlikely unless there is a specific technical issue or malicious intent.
