Exam Practice 1: Operating Systems

A forensic investigator is told that a server's processor that does not normally run high has been over-utilized lately, and they suspect possible malware. The investigator wants to start by investigating processes. Which command can they use to start the investigation? (Select two.)

ps

top

The ps command invokes the process table, a record that summarizes the currently running processes on a system.

The top command lists all processes running on a Linux system like ps. It acts as a process management tool by enabling users to prioritize, sort, or terminate processes interactively.

A helpdesk operator looks at build numbers for Windows as they plan upgrade timelines. The operator investigates the significance of the build numbers. Which of the following are the build numbers based on? (Select two.)

year and time of year

The number 16 in build 1607 corresponds to the year (2016) of release.

The 07 portion of build 1607 represents the month (07/July) of release. The current version of Windows 10 at the time of writing is 21H2, released in the second half of 2021.

Versioning is not part of it. Windows 10 and Windows 11 represent the currently supported versions of the Windows client OS.

The architecture is not part of it either. Each version and edition of Windows 10 was originally available as 32-bit (x86) or 64-bit (x64) software. A 32-bit CPU can only run the 32-bit editions. A 64-bit CPU can run either.

A user just installed a new application on their workstation, but the application has issues even starting up and communicating with the application server. The user has been working on the machine regularly up to this point without any prior issues. Which of the following is most likely the issue?

Firewall-

In this scenario, one place to troubleshoot is the host-based firewall. Select "Allow an app through the firewall" to allow or block programs (configure exceptions) from the Windows Firewall status page.

While proxy settings could be an issue, if the user is working fine beforehand, proxy settings are not likely to be an issue.

If the user has been using the machine without any previous problems it is unlikely that the domain name system (DNS) is the issue

A developer working at Microsoft is helping to develop the latest and greatest user interface for Windows. The developer is assigned to the team that works on the user interface's top level. What will the developer be working on?

The top level of the user interface is the desktop displayed when Windows starts, and the user logs on. Windows 11 makes several changes to the desktop style. Notably, it center-aligns the taskbar and introduces another design for the Start menu.

The desktop contains the Start menu, taskbar, and shortcut icons. These are all used to launch and switch between applications.

File management is a critical part of using a computer. As a computer support professional, users will often have to assist users with locating files.

Device Manager provides an advanced management console interface for managing system and peripheral devices.

A video game development company is purchasing upgraded laptops to develop cutting-edge graphics for a new story they have been marketing. They want the operating system to integrate persistent system RAM, offer Resilient File System (ReFS) support, and not require any additional license types. What type of operating system should they use for support?

Windows Pro for Workstations has many of the same features as Pro but supports more maximum RAM and advanced hardware technologies, such as persistent system RAM (NVDIMM).

Windows Pro is designed for usage in small- and medium-sized businesses and can be obtained using original equipment manufacturer (OEM), retail, or volume licensing.

The Enterprise edition has several features not available in the Pro edition, such as support for Microsoft’s DirectAccess virtual private networking technology, AppLocker, and more.

The Windows Home edition is designed for domestic consumers and possibly small office home office (SOHO) business use.

A Windows client administrator plans to upgrade their OS in the current environment. What is one of the most important considerations for the upgrade?

Explanation

Different desktop styles introduced by a new OS version or changing from one OS to another can generate issues as users struggle to navigate the new desktop and file system. An upgrade project must take account of this and prepare training programs.

While the scenario did not specify which OS the administrator was upgrading to, Windows 11 requires a CPU or motherboard supporting trusted platform module (TPM) version 2.

When data is written to an NTFS volume, it is re-read, verified, and logged via journaling. In the event of a problem, the sector concerned is marked as bad, and the data is relocated.

The Dynamic Disks feature allows multiple physical disks to be combined into volumes.

A senior systems administrator wants to convert the organization to a cloud-based email service. Which of the following should be considered

Explanation

Gmail can be used for enterprise environments through the use of the Google Workspace environment.

Exchange 2019 is an on-premise email service. Microsoft does have a cloud-based version of the management application known as Exchange Online.

Outlook 2024 is an email application used to manage an email account. It can download and send emails for a variety of accounts. Outlook Web is the cloud-based version of the application.

Postfix is an email server that was released in 1998 for the Linux operating system.

A user downloaded a script, but the file was in a text file format. The user needs to change the extension to a PowerShell script to run it, but they do not see the extension. Where can the user configure this setting?

On the File Explorer View tab, among many other options, users can configure hidden extensions, hidden files, and hide operating system files.

On the File Explorer General tab, users can set options for the layout of Explorer windows and switch between the single-click and double-click styles of opening shortcuts.

Ease of Access settings configure input and output options to best suit each user. There are three main settings groups.

The Internet Options Control Panel applet exposes the configuration settings for Microsoft’s Internet Explorer (IE) browser. The Security tab restricts what types of potentially risky active content are allowed to run.
