Answer 1

2. A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The virtual machine is comprised of a set of specification and configuration files and is backed by the physical resources of a host. Every virtual machine has virtual devices that provide the same functionality as physical hardware and have additional benefits in terms of portability, manageability, and security.

A virtual machine consists of several types of files that you store on a supported storage device. The key files that make up a virtual machine are the configuration file, virtual disk file, NVRAM setting file, and the log file. You configure virtual machine settings through the vSphere Web Client or the vSphere Client. You do not need to touch the key files.

A virtual machine can have more files if one or more snapshots exist or if you add Raw Device Mappings (RDMs).

3. ZTI (Zero Touch Installation) is a high-volume deployment strategy for midsize to large organizations that combines the use of MDT with System Center Configuration Manager (SCCM), which is part of the System Center family of products from Microsoft. Compared to the LTI approach that uses MDT with Windows Deployment Services, the ZTI approach to deployment using SCCM provides the following additional benefits:

Support for replication. (MDT requires using Distributed File System Replication.)

Support for performing multicast deployment. (MDT requires using Windows Deployment Services.)

Support for the bandwidth management of image transfers.

Support for reporting on driver availability for devices across your organization.

Support for complex repartitioning schemes and the formatting of disks. (This can also be done using MDT, but it requires custom scripting using Diskpart.)

Tolerance of poor or intermittent network connectivity.

Support for client operating system–initiated deployment.

Support for fully unattended deployment.

Support for offline deployment from media and CD/DVD spanning.

Support for encryption and password protection.

Although SCCM can be used by itself for deploying Windows to target systems, integrating MDT with SCCM provides certain additional advantages, such as task-sequence templates for different types of deployment scenarios, wizards to create packages and task sequences from MDT templates, wizards to create new boot images, and more.

4. Pagefile.sys is a windows system files, acts as swap file and was designed to improve performance. Windows uses it as RAM in case the application you're running on your computer ends up needing more RAM than you actually have. Usually page file is 1.5 times than your actual physical memory size, it is the recommended minimum size. The maximum size is 3 times than your actual physical memory size. Pagefile.sys is a hidden file. It means that you could see it in windows file manager only if you checked 'Show hidden files and folders' in Folder Options.

Can I delete pagefile.sys? As a system file you can’t simply delete it as you would for, say, a file that you yourself created but no longer wanted on your computer. To do so set both initial size and maximum size to zero, or click No paging file (Just right click on the workplace icon - either in start menu or on desktop - and select properties -> advanced -> performance options) then restart your computer. Your computer is no longer using pagefile.sys, and you can delete it now. To recover the pagefile.sys set some values to both initial size and maximum size the same way mentioned above. Microsoft strongly recommends that you do not disable or delete the paging file.

5.Prep the OS: Make sure that Windows is configured with all the required drivers and software infrastructure needed to support the new RAID controller.

Beware embedded gotchas: Windows Embedded installs are generated dynamically based on the system configuration at the time of installation. Updating this specialized OS to support RAID requires some workarounds, including using the command-line tool Deployment Image Servicing and Management (DISM) and restoring from modified backup after changing BIOS settings.

Mind the tools: The software used to manage RAID can come in two parts–a command line tool at the BIOS level and a graphical tool (such as Intel Rapid Storage Technology) at the OS level. Be clear on each tool’s role before the install.

Tell the vendor: If you run Windows Embedded, let the original vendor know before the update. They may be able to help with configuration details specific to your system hardware.

Prepare for the worst: Few IT situations are as desperate as a botched RAID deployment. Make sure you have backed up all your data and created system images to fall back to before you start.
