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.

Shreddingphysically destroys the platters, making data recovery virtually impossible. It ' s more effective and accessible than degaussing or low-level formatting.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Physical destruction methods like shredding are the most secure options for ensuring data on failed drives cannot be recovered."

The correct answer is C. Listen to the customer's concerns and acknowledge their frustrations, because effective communication and empathy are critical components of professional help desk interactions- especially when customers are upset.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, technicians should always demonstrate active listening, empathy, and professionalism. Acknowledging a user's frustration helps de- escalate tense situations and builds trust.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that users who feel unheard are less cooperative and more dissatisfied. Before troubleshooting or escalation, technicians should validate the customer's experience and reassure them that the issue will be addressed.
The Mike Meyers / Mark Soper Lab Manual reinforces that blaming previous technicians or immediately escalating without communication can worsen the situation. Asking technical questions too early may come across as dismissive.
Because the goal is to communicate professionally and effectively, the technician should first listen and acknowledge the user's frustration, making C the correct answer.

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.

The correct answer is A. .app, because macOS applications packaged as .app files are typically self- contained application bundles. This means that all required application files are stored within a single directory that appears as one file in Finder. When the .app file is moved to the Trash, the application is effectively removed from the system.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, macOS applications are commonly distributed as .app bundles, allowing for simple installation and removal. This design contrasts with Windows, where applications often install files across multiple directories and require uninstallers.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that dragging a .app file to the Trash is generally sufficient to uninstall the software, although some applications may leave behind preference files or caches. However, from an exam perspective, .app is the only option that supports this uninstall behavior.
The Mike Meyers / Mark Soper Lab Manual further clarifies that .msi and .exe are Windows formats, .rpm is used by Linux package managers, and .pkg installers often install system-wide components that require a formal uninstallation process.
Because .app files support simple drag-to-trash uninstallation, A is the correct answer.
