Accepted Answer

1. Use strong authentication: Passcode, PIN, Screen lock 2. Managing encryption: full disk encryption (on mobile devices) 3. Segmenting storage: Storage segmentation (separating business from personal data), containerization (storage is separated into containers) 4. enabling loss or theft services: (alarm, last known location, locate, remote lockout, thief picture), remote wipe

Question 6

What are 4 different support tools that can facilitate the management of mobile devices in an enterprise?

Accepted Answer

1. Mobile Device Management (MDM): Tools that allow a device to be managed remotely by an organization. 2.

Mobile Content Management (MCM): A system that is tuned to provide content management to mobile devices used by employees in an enterprise. 4. Unified Endpoint Management (UEM): A group or class of software tools has a single management interface for mobile devices as well as computer devices.

Question 7

What is an Embedded system?

Accepted Answer

Computer hardware and software contained within a larger system that is designed for a specific function.

Question 8

What are two different hardware components that can be used to create your own specialized devices?

Accepted Answer

Rasberry Pi: A low-cost credit-card-sized computer motherboard. Arduino Board: A controller for other devices (not as powerful)

Question 9

What is a field-programmable gate array (FPGA)?

Accepted Answer

A hardware integrated circuit (IC) that can be programmed by the user. Used in Rasberry Pi and Arduino for customizability

Question 10

What is system on a chip (SoC)?

Accepted Answer

A single microprocessor chip on which all the necessary hardware components are contained. Often uses real-time operating system (RTOS) (os designed specifically for SoC that processes high amount of data at once for quick decision making)

Question 11

What are some examples of a specialized systems?

Accepted Answer

smart meters: Digital meters that measure the amount of utilities consumed. Gives automatic meter readings as opposed to an analog meter Other examples: Medical systems, aircraft, vehicles heating, ventilation, and air conditioning (HVAC): Environmental systems that provide and regulate heating and cooling. multifunctional printer (MFP): A device that combines the functions of a printer, copier, scanner, and fax machine. Unmanned aerial vehicle (UAV)/Drones

Question 12

What are Industrial control systems (ICSs)? What are ICSs managed by?

Accepted Answer

Systems that control locally or at remote locations by collecting, monitoring, and processing real-time data to control machines. Managed by a supervisory control and data acquisition (SCADA), which controls the ICSs

Question 13

What is voice over IP (VoIP)?

Accepted Answer

A technology that uses a data-based IP network to add digital voice clients and new voice applications onto the IP network.
