Mobile Device Management (MDM) allows IT departments to enforce compliance controls, such as restricting the installation of unapproved software, on laptops and mobile devices.
* Why Not A (EDR): Endpoint Detection and Response focuses on detecting and mitigating security threats, not compliance controls.
* Why Not B (VPN): Virtual Private Networks provide secure connections but do not enforce software installation policies.
* Why Not D (SaaS): Software as a Service refers to software delivery models and does not enforce compliance controls.

A sandbox is a virtual environment that allows testing or running applications without affecting the main system. A sandbox can isolate the applications from the rest of the system, preventing any unwanted changes, errors, or security risks. A sandbox can also be easily reset to the initial state, discarding any modifications or data generated by the applications12.
A sandbox is a useful tool for stress testing multiple applications, as it can:
*Simulate different scenarios and conditions for the applications, such as high load, low memory, network latency, etc.
*Monitor and measure the performance, stability, and resource consumption of the applications under stress.
*Compare and analyze the results of different applications or different versions of the same application.
*Identify and fix any bugs, errors, or vulnerabilities in the applications before deploying them to the main system.

Category 7 (Cat 7) cables provide the best performance with the least Electromagnetic Interference (EMI) due to their enhanced shielding. Cat 7 cables are designed to support higher speeds and bandwidth while reducing interference compared to Cat 5 or Cat 6.
* Why Not A (Cat 5): Cat 5 cables have limited shielding and are prone to EMI, making them unsuitable for high-performance requirements.
* Why Not B (Cat 6): Cat 6 offers better shielding than Cat 5 but less than Cat 7.
* Why Not D (Coaxial): While coaxial cables are resistant to EMI, Cat 7 offers better performance overall for networking applications.

The most secure way to implement fingerprint readers would be to restrict device access to only the user to whom the laptop is assigned. This ensures that only authorized personnel have access to the device, reducing the risk of unauthorized access and data breaches.

Security groups are used to manage access permissions to network resources, ensuring only authorized HR department members can access the shared materials.
* Why Not B (Audit logs): Audit logs monitor activity but do not restrict access.
* Why Not C (Time-of-day access): Time-of-day access limits when users can access resources but doesn't specify user permissions.
* Why Not D (Print server): A print server manages print jobs but does not control file access.
