SCRIPT QUESTIONS AND ANSWERS SURE A+
✔✔Snapshots - ✔✔Key NTFS feature. This allows the Volume Shadow Copy Service to
make read-only copies of files at given points in time even if the file is locked by another
process. This file version history allows users to revert changes more easily and also
supports backup operations
✔✔Security - ✔✔Key NTFS feature. Features such as file permissions and ownership,
file access audit trails, quota management, and encrypting file system (EFS) allow
administrators to ensure only authorized users can read/modify file data
✔✔POSIX Compliance - ✔✔Key NTFS feature. To support UNIX/Linux compatibility,
Microsoft engineered NTFS to support case-sensitive naming, hard links, and other key
features required by UNIX/Linux applications. Although the file system is case-sensitive
capable and preserves case, Windows does not insist upon case-sensitive naming
✔✔Indexing - ✔✔Key NTFS feature. The Indexing Service creates a catalog of file and
folder locations and properties, speeding up searches.
✔✔Dynamic Disks - ✔✔Key NTFS feature. The disk management feature allows space
on multiple physical disks to be combined into volumes
,✔✔FAT32 (File Allocation Table) - ✔✔32-bit file system used principally for system
partitions and removable media.
Does not support any of the reliability or security features of NTFS.
✔✔exFAT (Extended File Allocation Table) - ✔✔A 64-bit version of the file allocation
table file system designed for use with removable hard drives and flash media.
Supports large volumes (128 petabytes) and file sizes (16 exabytes) There is also
support for access permissions but not encryption
✔✔ext3 - ✔✔The Linux file system that was the first to support journaling, which is a
technique that tracks and stores changes to the hard drive and helps prevent file system
corruption. A 64-bit file system.
✔✔ext4 - ✔✔The current Linux file system, which replaced the ext3 file system. Stands
for "fourth extended file system."
✔✔Apple File System (APFS) - ✔✔Default file system for macOS-based computers and
laptops. Supports journaling, snapshots, permissions/ownership, and encryption
✔✔Compatibility Concerns - ✔✔Considerations that must be made when using an app
in an environment with multiple device and OS platforms.
✔✔End of Life (EOL) - ✔✔Product life-cycle phase where mainstream vendor support is
no longer available
✔✔What feature of modern file systems assists recovery after power outages or OS
crash events? - ✔✔Journaling means that the file system keeps a log of updates that it
can use to recover damaged data. The OS might also make use of snapshot capability
to maintain a file-version history or perform continuous backups.
✔✔A customer asks whether an iOS app that your company developed will also work
on her Apple macOS computer. What issue does this raise, and what answer might you
give? - ✔✔The issue here is compatibility between different operating systems. Even
though both are produced by Apple, iOS and macOS use different environments, so the
iOS app cannot necessarily be installed directly. Your company might make a macOS
version. However, with the latest versions of macOS, there is support for native iOS
apps, so this might be something you can offer.
✔✔Apart from Windows and macOS, what operating system options are there for client
PCs installed to a local network? - ✔✔The other main choice is one of the distributions
of Linux. A company might also use some sort of UNIX. Finally, Chrome OS is installed
on Chromebox PCs. These are often used in educational institutions and businesses
that rely primarily on web applications rather than locally installed desktop software
,✔✔You are advising a customer with an older-model Android smartphone. The
customer wants to update to the latest version of Android, but using the update option
results in "No updates available" message. What type of issue is this and what advice
can you provide? - ✔✔This is an issue with update limitations. Android is quite a
fragmented market, and customers must depend on the handset vendor to implement
OS updates for a particular model. The customer can only check the handset vendor's
website or helpline to find out if a version update will ever be supported for that model.
✔✔32-bit (x86) or 64-bit(x64) - ✔✔Processing modes referring to the size of each
instruction processed by the CPU. 32-bit CPUs replaced earlier 16-bit CPUs and were
used through the 1990s to the present day, though most PC and laptop CPUs now work
in 64-bit mode. The main 64-bit platform is called AMD64 or EM64T (by Intel). Software
can be compiled as 32-bit or 64-bit. 64-bit CPUs can run most 32-bit software, but a 32-
bit CPU cannot execute 64-bit software.
✔✔Original Equipment Manufacturer (OEM) - ✔✔In PC terms, companies that sell
Windows co-branded under their own logo. OEM Windows licenses are valid only on
the system that the software was installed on, and the OEM must provide support.
✔✔BitLocker - ✔✔Feature of Windows allowing for encryption of NTFS-formatted
drives. The encryption key can be stored in a TPM chip on the computer or on a USB
drive.
Enables the user to encrypt all the info on a disk drive.
Not supported in Windows Home edition
✔✔Remote Desktop Protocol (RDP) - ✔✔Application protocol for operating remote
connections to a host using graphical interface. The protocol sends screen data from
the remote host to the client and transfers mouse and keyboard input from the client to
the remote host. It uses TCP port 3389.
The Windows Home edition had the RDP client software but it does not support an RDP
server.
✔✔Upgrade Path - ✔✔Earlier versions of an OS that support an in-place upgrade to a
newer version, retaining settings, third-party apps, and user data files
✔✔In terms of system hardware, what is the main advantage of a 64-bit version of
Windows? - ✔✔Support for more than 4 GB RAM
✔✔You are advising a business that needs to provision video-editing workstations with
4-way multiprocessing. Which retail Windows edition will allow them to make full use of
this hardware? - ✔✔Windows Pro for Workstations supports 4-way multiprocessing
(four CPUs installed to separate sockets) and up to 6 TB RAM. Windows Enterprise has
the same hardware limits but is not available via a retail channel.
, ✔✔You are advising a customer whose business is expanding. The business owner
needs to provision an additional 30 desktop computers, some of which will be installed
at a second office location. The business is currently run with a workgroup network of
five Windows 10 Home Premium desktop computers and one file server. Why might you
suggest licenses for an edition of Windows 10 that supports corporate needs for the
new computers and has upgrades for the old computers? Which specific edition(s)
could you recommend? - ✔✔Without a domain, accounts must be configured on each
computer individually. With more than 30 computers to manage at two locations, this
would be a substantial task, so switching to a domain network, where the accounts can
be configured on the server, is likely to save costs in the long term. You can suggest
either Windows 10 Pro or Windows 10 Enterprise for use on a domain.
✔✔Windows 10 Pro for Workstations - ✔✔A higher-end version of Windows 10 Pro for
expensive PCs with powerful hardware. The included features are already available on
the Windows Server but are moving over to a desktop version of Windows. The
maximum RAM for Windows 10 Pro for Workstations is 6TB.
Has BitLocker, Encrypting File System (EFS), Remote Desktop Protocol (RDP), Volume
Licensing, BranchCache, and is Domain Capable.
✔✔Windows Enterprise - ✔✔Has capabilities, such as using BitLocker, and Encrypting
File System (EFS). However, Windows 10 Enterprise maintains the Volume Licensing.
Additionally, Windows 10 Enterprise is primarily for use in corporate or business
applications, computers running Windows 10 Enterprise can exist on a domain,
meaning they're domain capable. The maximum RAM is 6 TB.
✔✔Windows 10 Home - ✔✔For the Small Office Home Office (SOHO) environment,
which means it has generally used smaller, limited-scope networks and has limited
features. Computers running Windows 10 Home cannot use BitLocker, EFS,
BranchCache, or existing on a domain, nor is there academic or volume licensing.
Maximum RAM is 128 GB.
✔✔A Windows administrator wants to become more familiar with Linux but still wants to
use Windows primarily. The administrator installs the bash subsystem for Windows and
is reading about how Windows has made strides to become more compatible with
Linux. Which of the following was part of the changes to the underlying New Technology
File System (NTFS) structure? - ✔✔Case-sensitive naming
✔✔A server administrator manages client images throughout their environment using a
Windows Deployment Server. However, the security team asks for a specific test box
that cannot be joined to the domain to test malware. Which of the following licenses
could the administrator use? - ✔✔Home
✔✔A developer needs a laptop that will run MySQL locally for their development
project. The minimum memory required is 16 GB of RAM. Which architecture should the
developer use? - ✔✔x64
