The CompTIA 220-1002 exam is one of two exams requires to obtain the CompTIA A+ (1000 series). This exam will focus on operating systems like Windows, OSX, and Linux.
1) Which option is a proprietary operating system made by Google for mobile devices like laptops and tablets?
Chrome OS is a proprietary operating system made by Google. It is mostly used on laptops known as Chromebooks. Android is not proprietary, the OS and it's source code can be found online for free. Many Android editions exist, some made by Google some made by others like Samsung or online communities.

Chrome OS is a Gentoo Linux–based operating system designed by Google It is derived from the free software Chromium OS and uses the Google Chrome web browser as its principal user interface Google announced the project in July 2009, conceiving it as an operating system in which both applications and user data reside in the cloud: hence Chrome OS primarily runs web applications Source code and a public demo came that November The first Chrome OS laptop, known as a Chromebook, arrived in May 2011 Initial Chromebook shipments from Samsung and Acer occurred in July 2011 Chrome OS has an integrated media player and file manager… Read More
2) Where can you find most applications installed on OSX and macOS?
/Applications is the location of most applications installed on Mac OSX and macOS. C:\Program Files\ and C:\Program Files (x86)\ are similar folders on Windows OS editions. Linux operating systems can greatly vary, but on many you can find many applications at /usr/bin.

3) Which of the following operating systems are Linux based?
Android is a mobile operating system that uses a custom Linux kernel. You can imagine a kernel as the brain of an operating system. The type of kernel used in an OS determines what type of OS it is. Linux flavors use a Linux kernel, Windows editions use the Windows NT kernel, iOS and macOS use Apple's XNU kernel (XNU itself is based on Unix). Easy right?

6) Which operating system installation type will wipe all existing data and partitions from the disk?
A clean installation will completely delete existing data and partitions on the chosen disk. It can be used to re-install the previous OS with a clean state, upgrade an OS or switch operating system types (e.g. from Windows to Linux). If data needs to be kept it should be backed up to a different drive or cloud provider first.
This question is filed under objective 1, Operating Systems
7) True or false:
All Linux applications can be run on macOS
An application built for one operating system cannot always be run on other operating systems. It will vary from application to application and support for each operating system must be enabled by the developers. Linux and macOS do have many similarities making it common for applications to be supported on both, but it is not automatic or guaranteed.
This question is filed under objective 1, Operating Systems
8) What operating system uses a web browser for most user facing functionality?
Google's Chrome OS is unique from other operating systems in that it primarily uses the web browser as it's user interface (Google Chrome). On some devices users can also install Android apps from the Google Play Store. It is not possible to run applications available for other operating systems like Windows and Mac on Chrome OS (unless they have a web version).

9) What is the maximum memory supported for the base editions of Windows 8 64-bit Windows 8.1 64-bit?
Windows 8 and 8.1 64-bit support a maximum of 128GB of memory. Other Windows 8 editions go as high as 512GB. This is a limit imposed by Microsoft and not a limit with 64-bit operating systems. In theory a 64-bit operating system can go as high as 16 Exabytes!

10) True or false:
Bitlocker is available for Microsoft Windows while EFS is a comparable disk encryption solution for Linux and Mac
Both Bitlocker and Encrypting File System (EFS) are solutions available to Microsoft Windows operating systems. Bitlocker encrypts an entire disk while EFS is a file-level encryption technology.
This question is filed under objective 1, Operating Systems
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 30 of NTFS that provides filesystem-level encryption The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer EFS is available in all versions of Windows except the home versions (see Supported operating systems below) from Windows 2000 onwards By default, no files are encrypted, but encryption can be enabled by users on a per-file, per-directory, or per-drive basis Some EFS settings can also be mandated via Group Policy in Windows domain environmentsCryptographic file system implementations for other operating systems are available, but the Microsoft EFS is not… Read More
11) Which option can be used to speed up a fresh installation of Windows 10 onto many computers?
An Unattended installation can be used to install Windows 10 without the usual user interface and configuration wizard. This is done by creating a new installer with an answer file which is used to configure the install without prompting the user to answer questions.

17) What acronym is used when a product or feature is no longer supported by the vendor?
The term End of Life (EOL) refers to a product or feature that is no longer supported by the vendor. While it may still function no new updates, security fixes or support will be offered by the vendor. Most software like applications and operating systems have an EOL date.
This question is filed under objective 1, Operating Systems
"End-of-life" ("EOL") is a term used with respect to a product supplied to customers, indicating that the product is in the end of its useful life (from the vendor's point of view), and a vendor stops marketing, selling, or rework sustaining it (The vendor may simply intend to limit or end support for the product) In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" ("EOS") The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view Different lifetime examples include toys from fast food chains (weeks or months), mobile phones (3 years) and cars (10 years)… Read More
18) True or false:
BranchCache is a feature available to Windows operating systems that allows reading and writing to cached files in the event connectivity is lost to the file server.
BranchCache allows files to be read even when a connection cannot be made with the file server. For example, if a warehouse loses connectivity to the file server in the corporate office hundreds of miles away BranchCache could be used to allow warehouse employees to read locally cached files. BranchCache does not support writing to files unless connectivity to the file server can be established.

19) Which boot method requires a network interface?
Preboot Execution Environment (PXE) is a special boot type that downloads an image from a server on the network. Fixed Drive is a boot type that uses an internal HDD or SSD. eSata is a type of external drive attachment. FTP is a protocol for transferring files and not a boot type.
This question is filed under objective 1, Operating Systems
In computing, the Preboot eXecution Environment (PXE, most often pronounced as pixie) specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard In modern data centers, PXE is the most frequent choice for operating system booting, installation and deployment… Read More
