Health Safety and Security at Workplace

Correct answer: A. People may have already seen, saved, or shared it

Deleting a post may remove it from the original account or platform view, but it cannot undo copies already downloaded, forwarded, archived, or captured in screenshots. Search caches or other records may also persist for some time. Therefore users should consider the possible audience and long-term effect before posting. A printer or mouse does not create or remove a digital footprint.

Correct answer: A. Privacy and digital etiquette

A photograph can identify a person and may reveal personal information or embarrass them when shared without consent. Respectful digital behaviour requires asking permission, considering the audience and purpose, and removing the image if the person objects. Privacy and digital etiquette therefore apply directly. Spreadsheet calculation, Print Preview, and the taskbar do not address consent or respectful sharing.

Correct answer: D. The connection may be secure, but the request is still suspicious

A lock usually indicates that the connection is encrypted; it does not prove that the website or its offer is trustworthy. A request for a password in exchange for a prize is a warning sign of phishing or fraud. Do not enter or share the password; verify the service through an independent official route.

Correct answer: B. Remove private files, sign out, and clear browser history

A public computer may retain downloaded files, an open session, or browsing history for the next user. Remove private downloads where appropriate, sign out of the account, and clear relevant history according to the system’s rules. Never save credentials or leave the account open; cleaning hardware does not protect the account.

Correct answer: A. Access permission

Access permissions define which users or groups may read, modify, or manage a shared file. The administrator can give teachers viewing or management rights while giving students no access or read-only access. Mouse speed, monitor brightness, and print colour affect use or appearance, not authorization to open or edit a file.

Correct answer: C. Connect only after confirming the correct network name

A familiar-looking network name may be fake, especially in a crowded public place. The student should confirm the exact name and connection details with the school, venue, or authorized provider before connecting, and avoid sensitive activity on an untrusted network. Choosing by appearance or connecting randomly is unsafe.

Correct answer: A. Wired networks use cables and wireless networks connect without cables, but both may need security

A wired network generally carries data through cables, while a wireless network uses radio communication instead of a physical cable for the link. Both still connect devices, exchange information, and require appropriate authentication, permissions, and protection. Wireless is not automatically unsafe and wired is not automatically risk-free.

Correct answer: A. Anyone can change the content

Edit permission allows a person to change text, delete material, or sometimes alter sharing settings. Giving it to everyone can lead to accidental or intentional changes, loss of work, or confusion about the final version. The safer practice is to give edit access only to collaborators who need it and view access to others.

Correct answer: A. Run a security scan and remove suspicious applications

Sudden slowness, pop-ups, and unknown applications can be warning signs of malware, although other technical causes are also possible. The safe response is to avoid suspicious links, disconnect when appropriate, run a trusted security scan, and remove or quarantine detected threats. Important files should not be deleted without diagnosis.

Correct answer: B. Do not share it and verify through an official source

A caller who creates urgency and asks for a payment PIN, one-time password, or other secret is showing a common sign of social engineering. The user should not disclose it, click links, or rely on the caller’s number. Instead, end the call and contact the bank or service through its official app, website, or known helpline.

Correct answer: A. Information may be intercepted and fake network risk may exist

A public wireless network may be poorly protected, maliciously configured, or imitated by an attacker. This can expose a user to fake login pages, harmful downloads, or attempts to intercept traffic, especially if a service is not using secure encryption. Banking is safer on a trusted network or mobile connection, with the official app and HTTPS used carefully.

Correct answer: A. Change the background or turn off the camera

A camera can reveal documents, identity details, addresses, screens, or other information that meeting participants do not need to see. The participant should move to a private setting, blur or replace the background, or turn off the camera when video is unnecessary. Sharing the information or a screenshot would increase the privacy risk.

Correct answer: B. Do not share without checking source and facts

Urgency, fear, and the absence of a source are warning signs that a message may be false or manipulative. Forwarding it without checking can spread misinformation and cause unnecessary harm. A responsible user should pause, inspect the original source, compare the claim with reliable information, and share it only if the facts and context are clear.

Correct answer: A. The post may have already been seen, saved, or shared

Deleting a post can remove it from the original account or platform view, but it cannot reliably undo what happened before deletion. Other people may have read it, taken screenshots, downloaded it, or forwarded it. This lasting possibility is called a digital footprint, so users should consider privacy and consequences before posting.

Correct answer: A. Proper shutdown helps close open work and system safely

A proper shutdown gives applications and the operating system an opportunity to save necessary information, close files, and stop processes in an orderly way. Directly removing power interrupts these operations and can cause loss of unsaved work, file corruption, or recovery checks when the computer restarts. It should be reserved for suitable emergencies.

Correct answer: A. Responsible use of Information and Communication Technology

Responsible ICT use involves more than operating a device. It includes finding relevant information, judging whether sources are trustworthy, storing data securely, selecting an appropriate communication method, and sending information only to the intended recipient. These connected actions show digital literacy and responsible information management, whereas the other options describe isolated or unrelated activities.

Correct answer: C. The request is suspicious and the source should be checked

A lock icon usually indicates that the connection is encrypted; it does not prove that the website or request is trustworthy. Unexpected requests for passwords, payment PINs, or other secrets may indicate phishing. Therefore, option C is correct. The user should verify the domain and source independently and never enter sensitive information merely because a lock is displayed.

Correct answer: C. The connection may be secure but the request is suspicious

A lock icon usually indicates that the connection is encrypted, but it does not prove that the website owner or every request is trustworthy. An unexpected password request tied to a free gift is a warning sign for phishing. The user should verify the source and avoid entering credentials. Thus C is the careful conclusion.

Correct answer: B. Check the source and facts

Fear-based language can pressure people to share before thinking, while the absence of a source makes the claim difficult to verify. A responsible user should identify the original source, compare the claim with reliable information, and check its date and context before forwarding. Immediate sharing or replying with a password increases risk, so B is correct.

Correct answer: A. Device security matters in local storage and account security matters in cloud storage

Local storage is kept on a device, so device access controls, physical protection, updates, and backups are important. Cloud storage is reached through an online account, so a strong password, sign-in protection, and careful sharing permissions matter greatly. Neither type is automatically secure, and local files do not normally open from everywhere without access arrangements.

Correct answer: A. Risk of infection from new harmful programs may increase

An unknown file may contain malware, especially when it comes from an untrusted source. Outdated antivirus software may lack current detection information, so it can miss newer threats or respond less effectively. Opening the file combines both risks. Updating protection, checking the source, and scanning files before opening them are safer practices.

Correct answer: A. Run a security scan and avoid suspicious applications

Slowness, unexpected messages, and unknown applications can indicate malware or another security problem, although they do not prove one by themselves. A security scan is a suitable first response, and avoiding suspicious links or programs prevents further harm. Clicking everything, sharing passwords, or deleting all files blindly can worsen the situation and destroy useful evidence.

Correct answer: A. A problem in one account can affect many accounts

Reusing one password creates a chain of risk. If an attacker learns it through one service, the same password may unlock the email, cloud files, and payment account. Different strong passwords limit the damage when one account is compromised; a password manager can help organise them. Reuse does not improve safety or affect hardware.

Correct answer: A. Password is still the first security layer

Two-step verification adds another check after or alongside the password; it does not replace the need for a good password. A strong unique password makes guessing and password-based attacks harder, while the second factor provides additional protection if the password is exposed. Together they create layered security. The other choices confuse security with unrelated computer functions.

Correct answer: B. Do not share it and verify through an official source

A payment PIN, one-time code, or similar secret should not be disclosed to an unexpected caller. Urgency and threats are common warning signs of fraud. End the call, do not use a number supplied by the caller, and contact the bank or service through its official app, website, or verified helpline. Sharing the code can permit unauthorised transactions.
