Show Suggested Answer Hide Answer
Suggested Answer: A

The tool that is used for natively running a Linux system in Windows is WSL. WSL, or Windows Subsystem for Linux, is a feature that allows users to run a Linux system natively on Windows 10 or Windows Server. WSL enables users to install and use various Linux distributions, such as Ubuntu, Debian, Fedora, etc., and run Linux commands, tools, applications, etc., without requiring a virtual machine or a dual-boot setup. WSL also provides users with interoperability and integration between Linux and Windows, such as file system access, network communication, process management, etc. WSL is useful for users who want to use Linux features or functionalities on Windows, such as development, testing, scripting, etc. The other options are either different tools or not related to running a Linux system in Windows at all. For example, Remote Desktop Protocol (RDP) is a protocol that allows users to remotely access and control another computer or device over a network; SSH, or Secure Shell, is a protocol that allows users to securely connect and communicate with another computer or device over a network; Telnet is a protocol that allows users to interact with another computer or device over a network using a text-based interface.Reference:CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.

Wait, aren't we supposed to use single quotes around the values? Like 'EmpId = '90030''? These SQL purists are getting out of hand!

C looks good to me. Selecting all columns from the employee table where EmpId = 90030 seems like the correct statement.

Haha, D is the winner! Who needs to specify the column when you can just select everything, right? #LazyProgrammer

I think B is the one with an error. The syntax should be 'SELECT EmpId FROM employee WHERE EmpId = 90030 AND DeptId = 34'.

D is the one with the error, it should specify a condition after 'FROM employee'.
