A) Apple
B) Symbian
C) Google
D) Yahoo

Accepted Answer

Google acquired Android code in 2005 and has since played a leadership role in its development. Apple has its own operating system (iOS), Symbian is no longer in business, and Yahoo does not develop operating systems.

Question 4

What is the accelerometer used for in mobile devices?
A) adjusting the screen orientation
B) geotracking

Question 5

iOS was developed by and continues to be maintained by a consortium of companies.

Accepted Answer

iOS was developed and is currently maintained solely by Apple Inc.

Question 6

What can you do if you want to obtain administrator privileges to an Android device?
A) delete the normal user account
B) logon as Admin
C) root the device
D) reboot into recovery mode

Accepted Answer

Rooting the device is the process of obtaining administrator privileges or root access to the device. This allows users to make changes and modifications to the system that are not normally allowed with a standard user account. Deleting the normal user account, logging on as Admin, and rebooting into recovery mode are not viable options for obtaining administrator privileges.

Question 7

If you want to be able to wear gloves while using a smart phone, which screen technology will work?
A) capacitive touch screen
B) iPod touch screen
C) resistive touch screen
D) retina display touch screen

Accepted Answer

Resistive touch screens will work with any object, including gloves, because they rely on pressure rather than capacitance to detect touch input. Capacitive touch screens, like those found on most smartphones, require the electrical conductivity of the human finger to register input. The iPod touch screen and retina display touch screen are both just specific types of capacitive touch screens.

Question 8

The Android OS is based on Linux.

Accepted Answer

The Android OS is based on the Linux operating system. Specifically, it uses a modified version of the Linux kernel.

Question 9

Which type of virtualization should you deploy to provide a Virtual Desktop Infrastructure?
A) server-side
B) client-side
C) fat-client
D) type-2

Accepted Answer

Server-side virtualization is the best choice for deploying a Virtual Desktop Infrastructure (VDI) as it allows multiple virtual desktops to run on a single physical server. This type of virtualization allows for central management and reduces the hardware and maintenance costs associated with traditional desktops. Client-side virtualization (B) is not ideal as it requires each user to have their own virtual machine installed on their local device, which can be resource-intensive and difficult to manage. Fat-client virtualization (C) involves installing a full operating system and applications on each client device, which can increase hardware and maintenance costs. Type-2 virtualization (D) is not recommended as it requires a host operating system and can impact performance.

Question 10

Which of the following is based on open source code?
A) Android
B) Blackberry
C) Windows Phone
D) iOS

Accepted Answer

Android is based on open source code, while Blackberry, Windows Phone, and iOS are not.

Question 11

What should you configure on an iOS device if you want your data erased after ten failed logon attempts?
A) Lock Screen
B) Remote Wipe
C) iOS Locator
D) Passcode Lock

Accepted Answer

The feature that allows for data to be erased after ten failed logon attempts is called the Passcode Lock. This feature can be found in the Settings app under Touch ID & Passcode (for devices with Touch ID) or Passcode (for devices without Touch ID). Once Passcode Lock is enabled, there is an option to erase data after ten failed attempts.

Question 12

You usually install an OS on a mobile device using a USB device or SD-card.

Accepted Answer

Mobile devices typically come with an OS pre-installed, and updates to the OS can be downloaded and installed directly on the device without the need for a USB device or SD-card. However, in some cases, it may be necessary to use a USB device or SD-card to restore or update the OS on a mobile device.

Question 13

What does jailbreaking do?
A) Allows you to download games for free from Google Play
B) Allows you download music for free from iTunes
C) give you administrative privileges to Android
D) give you root privileges to iOS

Accepted Answer

Jailbreaking specifically refers to the process of removing the limitations imposed by Apple on devices running iOS (like iPhones and iPads) to gain root access. This allows the user to install apps and make changes to the system that are not authorized by Apple.

Question 14

A SIM card is used for which of the following?
A) holding data related to your cellular carrier
B) holding your iTunes music information
C) controlling the sensitivity of your touch screen
D) backing up your data and applications

Accepted Answer

A SIM card is specifically designed to store data related to the cellular carrier that a user subscribes to, including phone number, network authentication data, and other personal information. It allows a user to connect to their carrier's network and access various services such as making calls, sending texts, and using data. SIM cards do not hold any data related to iTunes, touch screen sensitivity, or backup of data and applications.

Question 15

The delegation of server-side virtualization to a third party is referred to as which of the following?
A) zero client infrastructure
B) cloud computing
C) presentation virtualization
D) App-V

Accepted Answer

Cloud computing is the delegation of server-side virtualization to a third party, who provides a cloud-based infrastructure for hosting and managing virtual machines. Zero client infrastructure refers to a client-side virtualization approach, while presentation virtualization and App-V are specific virtualization technologies rather than broad concepts like cloud computing.

Question 16

A setting called airplane mode lowers the output power of the Wi-Fi and Bluetooth antennas allowing these networks to function, but at a reduced range.

Accepted Answer

Airplane mode disables the Wi-Fi and Bluetooth antennas, preventing these networks from functioning unless manually re-enabled while in airplane mode.

Question 17

Which of the following is NOT a function provided by iTunes for iOS devices?
A) sync data to your computer
B) install iOS updates
C) back up data on Apple web sites
D) restore from backup

Accepted Answer

iTunes can sync data from iOS devices to the computer, install iOS updates, and restore from a backup. However, it does not back up data on Apple web sites. iCloud is the service provided by Apple for data backup and synchronization among different iOS devices.

Question 18

VMs running under a Type 1 hypervisor are isolated from each other.

Accepted Answer

Type 1 hypervisors, also known as bare-metal hypervisors, run directly on the host machine's hardware and provide a layer of abstraction between the physical hardware and the virtual machines running on it, ensuring their isolation from each other.

Question 19

Which of the following is a screen that uses electrodes that sense the conductive properties of skin?
A) dual-touch screen
B) capacitive touch screen
C) pressure-sensing screen
D) resistive touch screen

Accepted Answer

A capacitive touch screen uses electrodes that sense the conductive properties of skin, making it the best choice among the given options. Dual-touch screens use both capacitive and resistive technologies, pressure-sensing screens sense the amount of force applied to the screen, and resistive touch screens use layers of conductive material that are pressed together when touched.

Question 20

What must you do before using a new iPad or iPod touch?
A) register it
B) activate it
C) install iOS on it
D) install iTunes on it

Accepted Answer

Before using a new iPad or iPod touch, it must be activated. This involves connecting the device to iTunes and following the on-screen instructions to set up and register the device. Installing iOS and iTunes may also be necessary, but activating the device is the first step.
