Correct answer:

Explanation: 1 – IR 2 – Bluetooth 3 – NFC 4 – Tethering

Correct answer: Continuous reboots

Continuous reboots are a primary indicator of faulty RAM as defective memory modules cause system instability during the boot process and normal operation. Unlike POST code beeps which indicate various hardware issues, distended capacitors which are power supply related, or wrong BIOS time which indicates CMOS battery problems, continuous reboots specifically point to memory-related failures that prevent stable system operation.

Correct answers: Remove the case and organize the parts.; Document the screw locations.

When assessing liquid damage to verify repairability before providing a cost estimate, the technician must first remove the case and organize the parts to properly inspect internal components for corrosion, short circuits, or other damage. Additionally, documenting screw locations during disassembly is essential for proper reassembly and professional service. Searching the Internet for tutorials, consulting colleagues, or placing the device in rice are not appropriate next steps for professional damage assessment - they either delay the process or are ineffective remedies for liquid damage.

Correct answers: Barcode scanner; Magnetic reader

Barcode scanners are essential for quickly taking inventory as they can rapidly read product barcodes to identify items and update inventory systems in real-time. Combined with magnetic readers for payment cards, these devices create an efficient inventory and pricing system. Barcode scanners eliminate manual data entry errors and significantly speed up the inventory process compared to manual recording methods.

Magnetic readers work in conjunction with barcode scanners to create a complete inventory and pricing solution by reading magnetic stripe cards for employee access, payment processing, or inventory tracking cards. This combination allows companies to both scan product barcodes for inventory updates and process magnetic stripe data for comprehensive inventory management and price tag updates.

Correct answer: Duplex

Duplex printing is the specific setting that enables automatic printing on both the front and back sides of paper, which is exactly what the user requested for their large print job. Collate organizes multi-page documents, orientation controls portrait/landscape layout, and transparency is a paper type setting - none of these enable double-sided printing like duplex does.

Correct answers: Document findings, actions, and outcomes.; Run a virus scan.

After successfully resolving the malware issue and verifying connectivity works, documenting findings, actions, and outcomes is essential according to CompTIA troubleshooting methodology. This step ensures proper record-keeping for future reference, helps identify patterns, and provides documentation for the customer. The other options like rebooting, reconnecting, or checking IPConfig are unnecessary since connectivity is already verified working.

Running a comprehensive virus scan is the appropriate next step to ensure complete malware removal and prevent reinfection. Even though the immediate connectivity issue is resolved, a thorough scan helps identify any remaining malicious components that might not have been caught in the initial malware removal process. This proactive measure follows best practices for malware remediation procedures.

Correct answer: ipconfig /flushdns

When a user can access local intranet but not external sites, and ping by name fails while local access works, this indicates a DNS resolution problem. The ipconfig /flushdns command clears the local DNS cache, removing potentially corrupted or outdated DNS entries that may have accumulated during the user''s absence. The other options like /all (displays configuration), /release (releases IP), or /setclassid (sets DHCP class) do not address DNS resolution issues.

Correct answer: Input voltage

Input voltage is the most critical PSU specification for a computer used at international trade shows, as different countries use different electrical standards (110V vs 220V). A PSU with dual voltage capability or automatic voltage switching ensures the system will work reliably worldwide. Efficiency rating, 12V rail amperage, and SATA connectors are important but won''t prevent the system from working entirely if the input voltage is incompatible with local power.

Correct answer: Set the laptop configuration to DHCP to prevent conflicts.

Setting the laptop to DHCP configuration resolves IP address conflicts by allowing the network''s DHCP server to automatically assign an available IP address instead of using a static IP that may already be in use. This is the standard solution when receiving ''IP address already in use'' error messages on corporate networks. Static IP removal, network card replacement, and bridging connections would not address the core IP conflict issue.
