A technician needs to implement password requirements that apply to all domain-joined computers. Which of the following commands should the technician most likely run?
Detailed
The correct command is gpupdate (Option A), which refreshes Group Policy settings. To implement password requirements across domain-joined computers, the policy would be set via Group Policy, and then running the gpupdate command ensures that the new settings are applied to all systems.
devmgmt (Option B) opens Device Manager, which is unrelated to Group Policy.
regedit (Option C) opens the Windows Registry Editor, which is not used for group-wide password policy settings.
resmon (Option D) opens Resource Monitor, which helps monitor system resources, not Group Policy.

A technician is installing an operating system on a new computer. Which of the following is the first step of the process?
Detailed
The first step in installing an operating system on a new computer is Setting the boot order (Option A). This ensures that the computer can boot from the installation media (USB, DVD, etc.). Once the boot order is configured, the system can start from the installation source, and the rest of the OS installation process can proceed.
Formatting the hard drive (Option B) comes later in the process, after the installation media is booted.
Entering the product key (Option C) and Selecting the filesystem (Option D) are subsequent steps during the installation process.

A user reported that Windows has crashed several times during the day. A technician needs to check error messages to determine whether the issue pertains to the hardware or an application. Which of the following tools should the technician use?
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.

After a computer upgrade at an imaging lab. the upgraded computers are not able to obtain an IP address. Which of the following is most likely the issue?
When upgraded computers are not able to obtain an IP address, the issue often lies in the network configuration. Here's a detailed explanation:
Option A: The switch is only providing IPv6 addresses. This is unlikely because if the switch were providing IPv6 addresses, the devices would still receive an IP address, albeit an IPv6 one. The issue described indicates no IP address is being obtained at all.
Option B: The OS must be updated to be compatible with the imaging software. This option is unrelated to obtaining an IP address. Compatibility with imaging software would not prevent the devices from getting an IP address.
Option C: The switch has port security enabled. Correct Answer. Port security on a switch restricts access based on MAC addresses. If the MAC addresses of the upgraded computers are not recognized or have not been added to the allowed list, the switch will not provide network access, resulting in the computers not obtaining an IP address.
Option D: The switch does not support multicast traffic. This is unrelated to obtaining an IP address. Multicast traffic deals with specific types of network communication and would not affect the basic DHCP IP address assignment process.
A company's help desk receives numerous calls from employees reporting issues related to a current security breach. Which of the following steps should the help desk team take to document the breach?
In the event of a security breach, documenting the incident is crucial for tracking, analysis, and resolution. The appropriate steps should ensure thorough documentation and communication:
Option A: Record the details in the ticketing system. Correct Answer. The ticketing system is the primary tool for IT support to track incidents. Recording the details in the ticketing system ensures that all relevant information is documented systematically, can be easily accessed, and tracked through the resolution process.
This aligns with best practices in incident documentation and support systems information management as outlined in the CompTIA A+ Core 2 (220-1102) Exam Objectives, Section 4.1.
Option B: Take screenshots and attach them to the root cause analysis. While screenshots can be useful, the first step should be to record the details in the ticketing system. Screenshots may be added later as supplementary information.
Option C: Discuss the incident with the company's legal team. Involving the legal team is important for certain aspects of a security breach, but the initial step should still be to document the incident in the ticketing system.
