Which of the following is an example of an application publisher including undisclosed additional software in an installation package?

1. A. Virus
2. B. Ransomware
3. C. Potentially unwanted program
4. D. Trojan

Correct Answer: C
Comprehensive and Detailed Explanation From Exact Extract:
A Potentially Unwanted Program (PUP) is software that a user may not have knowingly installed. It often gets bundled with legitimate software and installs without full disclosure. PUPs can affect performance, change system settings, or display unwanted ads but are not necessarily malicious like viruses or ransomware.
* A. Viruses replicate and spread; they are generally more harmful and not "bundled" in the same way.
* B. Ransomware encrypts files for payment and is deliberately malicious.
* D. A Trojan disguises itself as legitimate software to perform malicious actions but is not typically pre-bundled by legitimate publishers.

A technician is using a credential manager to safeguard a large number of credentials. Which of the following is important for using this application?

1. A. Restricted log-in times
2. B. Secure master password
3. C. TPM module
4. D. Windows lock screen

Correct Answer: B
Comprehensive and Detailed Explanation From Exact Extract:
Credential managers or password vaults (e.g., Windows Credential Manager, KeePass, or LastPass) store passwords securely. The integrity of such tools heavily depends on the strength of the master password protecting the vault. If compromised, all saved credentials could be exposed. Therefore, setting a secure master password is crucial.
* A. Login time restrictions are general user account settings, not specific to credential managers.
* C. TPM is used more commonly for full disk encryption, not specifically required for password managers.
* D. The lock screen protects general access but does not protect stored credentials alone. Reference:

Every time a user loads a specific spreadsheet, their computer is temporarily unresponsive. The user also notices that the title bar indicates the application is not responding. Which of the following would a technician most likely inspect?

1. A. Anti-malware logs
2. B. Workstation repair options
3. C. Bandwidth status as reported in the Task Manager
4. D. File size and related memory utilization

Correct Answer: D
Comprehensive and Detailed Explanation From Exact Extract:
If a system becomes unresponsive while opening a specific spreadsheet, the issue is likely tied to the file??s size or the complexity of its content (e.g., embedded formulas, macros, or graphics). High memory utilization caused by the file can lead to temporary freezing or application "Not Responding" messages. Checking the spreadsheet's file size and monitoring system memory in Task Manager will help isolate performance bottlenecks.
* A. Anti-malware logs are important for security troubleshooting but less likely relevant to spreadsheet-related performance issues.
* B. Workstation repair is for system-wide problems and not necessary for a single-file issue.
* C. Bandwidth relates to network usage and wouldn??t impact opening a local file. Reference:

A user receives a new personal computer but is unable to run an application. An error displays saying that .NET Framework 3.5 is required and not found. Which of the following actions is the best way to resolve this issue?

1. A. Resolve the dependency through the 'Turn Windows features on or off' menu.
2. B. Download the dependency via a third-party repository.
3. C. Ignore the dependency and install the latest version 4 instead.
4. D. Forward the trouble ticket to the SOC team because the issue poses a great security risk.

Correct Answer: A
Comprehensive and Detailed Explanation From Exact Extract:
NET Framework versions are often required for applications to run. If an older app requires
.NET Framework 3.5, it must be explicitly installed as it is not included by default in newer versions of Windows. The best method to do this safely is through the built-in "Turn Windows features on or off" utility, which downloads and installs it via official Microsoft services.
* B. Using third-party repositories is unsafe and not recommended.
* C. Installing .NET 4 does not include 3.5; versions are not fully backward compatible.
* D. The issue is technical, not a security incident for the SOC team. Reference:
