Correct Answer: C
Comprehensive and Detailed In-Depth Explanation: High resource usage along with frequentpop-upsare strong signs of amalware infection. The next logical step is toupdate anti-malware definitionsandrun a full scanto detect and remove threats. * Option A:Network performance is likely not the root cause - local system behavior points to malware. * Option B:Drivers affect hardware functionality; they don't resolve malware-related slowness. * Option D:DHCP issues usually cause IP conflicts or no network access, not CPU spikes or pop-ups. CompTIA A+ Core 1 Exam Objective Reference: * Objective 4.2: Given a scenario, detect, remove, and prevent malware using appropriate tools and methods.
Question 18
Which of the following is the best to use when testing a file for potential malware?
Correct Answer: D
Comprehensive and Detailed Explanation From Exact Extract: A sandbox is a secure, isolated environment used to test potentially harmful software or code.

Thismethod is standard in cybersecurity best practices. #Reference: "CompTIA A+ Certification All-in-One Exam Guide" by Mike Meyers - Chapter 28, page 1230.
Question 19
A third-party contractor recently installed a new switch, router, and cabling for a small corporate office. After the installation, users started experiencing issues connecting to resources over the network. INSTRUCTIONS Click on each PC and server to review outputs. From the remediation section on the right, select an issue and solution for each device.
Correct Answer:
See the Explanation and detailed steps below. Explanation: Looking at the network configurations and outputs from both PCs and servers, here are the possible issues and solutions: 1. PC 1 Issue: The IP address for PC1 is 192.168.1.1, which conflicts with Server 1 (which also uses 192.168.1.1). Solution: Change the IP address on PC1 to a unique one within the range, like 192.168.1.3. 2. PC 2 Issue: PC 2 is configured with 192.168.1.2, which conflicts with Server 2 that has the same IP address. Solution: Update the IP address on PC 2 to something unique, like 192.168.1.4. 3. Server 1 Issue: The IP address for Server 1 is 192.168.1.1, which conflicts with PC1. Solution: Since Server 1 and PC1 are using the same IP address, change one of them. For Server 1, you could change the IP address to 192.168.1.5. 4. Server 2 Issue: Server 2 is using the IP address 192.168.1.2, which conflicts with PC2. Solution: Update Server 2 to use a different IP address, such as 192.168.1.6. General Remediation: The primary problem here is overlapping IP addresses, leading to connectivity issues. Each device on the network must have a unique IP address. After making these changes, ensure that all devices can communicate properly by testing the connection between devices and verifying they can access shared resources.
Question 20
The output from a dot matrix printer has become lighter over time. Which of the following should a technician do to fix the issue?

Replacing the ribbon restores print quality. * Option A:Cleaning helps with image clarity, not ink density. * Option C:Maintenance kits apply to laser printers, not dot matrix. * Option D:Calibration affects print position, not darkness. CompTIA A+ Core 1 Exam Objective Reference: * Objective 3.7: Given a scenario, troubleshoot common printer problems.
