Detailed

A rootkit (Option A) is a type of malware designed to gain administrative (root) access to a system while hiding its presence. Rootkits can manipulate system processes and files to remain undetected, making them particularly dangerous.

Trojan (Option B) is malware disguised as legitimate software but doesn't necessarily provide administrative access.

Worm (Option C) spreads across networks but doesn't grant administrative access.

Ransomware (Option D) encrypts data and demands a ransom but doesn't typically provide ongoing administrative access.

PowerShell (Option C) is a powerful scripting language used in Windows environments for automating tasks, including the configuration of services across multiple systems. It is widely used by system administrators for scripting and automating administrative tasks.

SQL (Option A) is used for managing databases, not for scripting system configurations.

HTML (Option B) is a markup language for web development, not for automating services.

C# (Option D) is a general-purpose programming language but is not primarily used for administrative automation tasks.

Detailed

The net use (Option D) command is used to manage network drives in Windows. It can be used to display and disconnect mapped network drives, making it the correct choice for removing unused network drives.

format (Option A) is used to format disks, not for managing network drives.

netstat (Option B) displays network connections but doesn't manage network drives.

diskpart (Option C) is used for disk partitioning, not network drive management.

rmdir (Option E) is used to remove directories, not network drives.

The most likely solution to this issue is to enable cellular data. After a business trip, the user may have disabled cellular data to avoid roaming charges, or the phone may have been set to Wi-Fi only for internet access. Enabling cellular data would restore internet access outside of Wi-Fi networks.

The first step is to check the system event logs using tools like Event Viewer. This will allow the technician to identify any critical errors or warnings that occurred before the restart. Based on these logs, further troubleshooting can be done. Verifying driver versions and performing diagnostics can follow once the root cause is identified.

A rollback plan is essential for a change to be approved by a change management review board. It outlines the steps to reverse a change in case something goes wrong, minimizing downtime and mitigating risk. Other items like end-user acceptance and cost analysis are important but not typically the deciding factor for approval.

Drilling is a method of physically damaging the hard drive by drilling holes through it, which renders the drive inoperable. However, it is not a secure method for ensuring data cannot be recovered. Methods such as wiping or degaussing are more secure.

Detailed

Event Viewer (Option A) is the appropriate tool to check for system and application logs, including error messages and crash reports. It helps the technician determine the cause of the crashes by reviewing logged events.

Resource Monitor (Option B) tracks real-time usage of system resources but doesn't log errors.

Performance Monitor (Option C) monitors system performance but isn't primarily used for crash diagnostics.

Device Manager (Option D) manages hardware devices but doesn't provide crash logs.

Cross-site scripting (XSS) (Option C) allows attackers to inject malicious scripts into web pages viewed by users. When the user visits the compromised site, the script runs in the user's browser, potentially allowing the attacker to steal data or perform unauthorized actions. XSS is a common vulnerability in web applications that allows code execution.

DoS (Option A) disrupts services but doesn't involve executing code on a user's device.

Spoofing (Option B) involves impersonating another device or user but doesn't execute code.

SQL injection (Option D) attacks a database and is unrelated to executing code on the user's computer.
