Security+ Lesson10

Which of the following contains a 64-bit ARM CPU and supports Linux natively and has the resources and hardware to run the operating system and services?

• RTOS

• System on a Chip

• FPGA

• Raspberry Pi

Answer explanation

Raspberry Pi is a series of embedded computers developed by the Raspberry Pi Foundation. It was initially intended for teaching computer science, later it became a wildly popular platform for robotics, automation systems, and all sorts of other specialized computing applications. A Raspberry Pi is a small but complete computer, with a 64-bit ARM CPU, between 512 MB and 8 GB RAM, and with a MicroSD card slot for storage. For I/O, it has one to five USB ports, HDMI and composite video, 3.5mm audio, and low-level general-purpose I/O (GPIO) pins. Most models have an Ethernet port, and many have Wi-Fi and Bluetooth as well. It can run various operating systems, including Linux, Android, and Windows 10 IoT core.

Steffie wants to select a mobile device deployment method that provides employees with devices that are company-issued and supported, but employees can use them for personal reasons too. Which of the following is the most likely culprit?

• COPE

• COBO

• BYOD

• CYOD

Answer explanation

Steffie's requirements fit the Corporate Owned, Personally Enabled (COPE) device deployment model. It is a more relaxed version of Corporate Owned, Business Only (COBO). Devices are company-issued and supported, but employees can use them for personal reasons too. Exactly what apps they can install and use, or other acceptable use policies, are still up to the employer.

What kind of policy governs a set process for how an employee needs to prepare a device to join the program?

• Onboarding

• Offboarding

• Asset tracking

• Storage segmentation

Answer explanation

Onboarding governs a set process for how an employee needs to prepare a device to join the program.

Which of the following is used to monitor state changes in large scale distribution systems such as electrical grids, waste control systems, and transportation?

• DCS

• VoIP

• SCADA

• IoT

Answer explanation

Supervisory Control and Data Acquisition (SCADA) was developed to monitor state changes in large scale distribution systems such as electrical grids, waste control systems, and transportation.

In which of the following can the employee choose between a list of devices the company has approved for security features and support?

• GPS

• CYOD

• Asset tracking

• BYOD

Answer explanation

Choose Your Own Device (CYOD) is a stricter alternative to BYOD, where employees can choose between a list of devices the company has approved for security features and support. Employees might be expected to pay for their devices, or the company might subsidize its purchase. CYOD is harder to secure and support than corporate-owned devices, but easier than BYOD.
