Question 4

What process gives a user access to a file system on a mobile device with full permissions,essentially allowing the user to do anything on the device?

Accepted Answer

Jailbreaking is a process that allows a user to gain full control of a mobile device's file system, bypassing the device's security measures and restrictions. This gives the user root access, allowing them to install custom software, modify system files, and perform other tasks that are typically restricted on a non-jailbroken device. Mirroring, sideloading, and carrier unlocking are unrelated processes and do not provide full access to a mobile device's file system.

Question 5

How is the coverage area for a cellular telephony network usually divided in a typical city?

Accepted Answer

The coverage area for a cellular telephony network is typically divided into hexagon-shaped cells. This shape is used because it allows for efficient coverage and minimal overlap between cells. Hexagons closely approximate circles (which would be the ideal shape for coverage) while allowing for a tessellated, gapless layout, making them the practical choice for cellular networks.

Question 6

What portable computing devices,designed for user convenience,have a sensor called an accelerometer that senses vibrations and movements that can determine the orientation of the device?

Accepted Answer

Tablets are portable computing devices that are designed for user convenience and typically have an accelerometer sensor that can determine the orientation of the device based on movements and vibrations. Laptops, notebooks, and subnotebooks may not always have this sensor, or the sensor may not be as sensitive or accurate as in tablets. Therefore, the best choice is C) tablets.

Question 7

Which option allows a mobile device to be configured so that the device automatically unlocks and stays unlocked until a specific action occurs?

Accepted Answer

Context-aware authentication allows a device to automatically unlock and remain unlocked based on specific contexts, such as location or connection to a trusted device, until a predefined condition changes.

Question 8

Which enterprise deployment model allows users to use their personal mobile devices for business purposes?

Accepted Answer

BYOD (Bring Your Own Device) is the enterprise deployment model that allows users to use their personal mobile devices for business purposes. With this model, employees can use their own devices to access company resources, apps, and data, which makes it a convenient and cost-effective option for organizations. It also allows employees to have greater control and choice over the devices they use for work. Other deployment models like COPE (Corporate-Owned Personally Enabled), VDI (Virtual Desktop Infrastructure), and CYOD (Choose Your Own Device) involve providing employees with company-owned devices or giving them a limited choice of devices to use.

Question 9

Which of the following is NOT an Android Smart Lock configuration option?

Accepted Answer

User device detection is not an Android Smart Lock configuration option. The other options (Trusted places detection, On-body detection, Trusted face) are all valid Android Smart Lock configuration options.

Question 10

What type of update service can Apple users take advantage of to update their operating systems via wireless carriers?

Accepted Answer

OTA (Over the Air) is the type of update service that Apple users can take advantage of to update their operating systems via wireless carriers. This allows users to download and install updates directly on their devices without having to connect them to a computer.

Question 11

Select the item that is not considered to be a basic characteristic of mobile devices.

Accepted Answer

While small form factor, a mobile operating system, and data synchronization capabilities are all basic characteristics of mobile devices, removable media storage is not essential. Many mobile devices have fixed internal storage and rely on cloud storage for additional storage needs.

Question 12

What type of technology can add geographical identification data to media such as digital photos taken on a mobile device?

Accepted Answer

GPS tagging refers to the process of adding geographical identification data to media, such as digital photos, using GPS technology.

Question 13

Which of the following frameworks requires a QR code or PIN on each IoT device for authenticating it to the network,and uses an Elliptic Curve Diffie-Hellman secure key exchange and a Transport Layer Security (TLS)tunnel?

Accepted Answer

The Security 2 (S2) framework requires a QR code or PIN on each IoT device for authenticating it to the network and uses an Elliptic Curve Diffie-Hellman secure key exchange and a Transport Layer Security (TLS) tunnel. The other frameworks do not specifically mention these authentication and security measures.

Question 14

Select the proprietary wireless network technology that is used primarily by sensors for communicating data.

Accepted Answer

ANT is a proprietary wireless network technology that is commonly used by sensors for transmitting data. It is a low-power wireless technology that is designed specifically for the transmission of sensor data, making it ideal for use in applications such as sports and fitness tracking, home automation, and healthcare monitoring. Bluetooth and USB are also wireless technologies, but they are generally used for different purposes and are not as well-suited for sensor networks. SCD is not a common or well-known wireless technology.

Question 15

What systems control locally or at remote locations by collecting,monitoring,and processing real-time data so that machines can directly control devices such as valves,pumps,and motors without the need for human intervention?

Accepted Answer

The answer of What systems control locally or at remote...

Question 16

Which of the following systems is located in a satellite and regenerates a signal that is sent back to earth at another frequency?

Accepted Answer

A repeater system is commonly used in satellites to receive signals from one frequency and regenerate them on another frequency to strengthen the signal for transmission back to earth. The other options, such as cell transmitters, RF receivers, and modulators, have different functions and are not typically located in satellites.

Question 17

Which enterprise deployment model requires employees to choose from a selection of company owned and approved devices?

Accepted Answer

COPE (Corporate Owned, Personally Enabled) requires employees to choose from a selection of company owned and approved devices.

Question 18

What mobile operating system below requires all applications to be reviewed and approved before they can be made available in the App store?

Accepted Answer

iOS requires all applications to go through a review and approval process before they can be released on the App Store. This is to ensure that the apps meet Apple's guidelines and standards for quality, security, and content. Android, Blackberry OS, and Symbian do not have the same strict approval process for their app stores.

Question 19

What type of software is specifically designed for a SoC in an embedded system?

Accepted Answer

An embedded system typically uses a microcontroller or a microprocessor with some peripherals like memory, communication interfaces, and other I/O devices all integrated into a single chip. Real-time operating systems (RTOS) are specifically designed to manage a system's resources and tasks, which makes them ideal for managing the applications and tasks of embedded systems. So, the best choice for software designed for an SoC in an embedded system is an RTOS.

Question 20

Which of the following can replace using radio frequency (RF)for the communication media?

Accepted Answer

Infrared can replace using radio frequency for the communication media. Infrared uses light waves to transmit data, whereas RF uses radio waves. Infrared is typically used for short-range communication, such as between a remote control and a device, but it can also be used for data transmission in some settings. ANT and Bluetooth are both forms of wireless communication that use RF, and repeaters are devices that amplify RF signals.
