CompTIA 220-1102 Exam Questions

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.

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.

3.1 - Troubleshoot common Windows OS problems using tools like Event Viewer

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.

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.

In this scenario, the user cannot access a separate subnet, and all other checks (credentials, network stability, and permissions) have been verified. The next logical step is to check if the user's IP address is being blocked by a firewall.

Option A: Consult with the firewall team to see if the user's IP address is blocked Firewalls can block specific IP addresses, preventing access to certain network segments. Given the problem's nature and the steps already taken, this is the most logical next step to ensure the user's IP is not inadvertently blocked.

Option B: Delete the user's credentials and create new ones This step is unnecessary since the credentials have already been verified as correct.

Option C: Run a virus scan on the user's workstation While important for overall security, a virus scan is unlikely to resolve an issue specific to accessing a subnet if the problem does not affect other users.

Option D: Update the network drivers on the user's workstation If the network connection is stable and the issue is isolated to accessing a specific subnet, network drivers are unlikely to be the cause.
