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.

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.

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 The ipconfig /flushdns command clears the local DNS cache, removing potentially corrupted or outdated DNS entries that may have accumulated during the user''s absence.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.

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.

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.

A four-core processor is essential for a home computer used for internet browsing, video streaming, and gaming, as it provides sufficient processing power for multitasking and running modern games. Gaming applications benefit significantly from multiple cores for handling game logic, audio processing, and background tasks simultaneously while maintaining smooth performance for streaming and web browsing.

Sufficient memory (16GB) is crucial for a computer that will handle gaming, video streaming, and web browsing, as modern games and video applications require substantial RAM for optimal performance. Adequate memory prevents system slowdowns when running multiple applications simultaneously and ensures smooth gaming experiences while supporting background processes for streaming and browsing.

Ethernet cable is the standard connection between a cable modem and SOHO router, typically using CAT5e or CAT6 Ethernet cable with RJ45 connectors. This provides reliable high-speed data transfer between the modem and router for internet connectivity. Thunderbolt is for high-speed peripherals, coaxial connects the modem to the cable provider, and USB is not suitable for this type of network connection.

Channel 6 is one of the three non-overlapping channels (1, 6, and 11) commonly used in 802.11b/g/n wireless networks operating in the 2.4 GHz band. These channels are spaced to avoid interference with each other and are the standard recommendations for optimal wireless performance. The other options (17, 802, 8080) are not valid 802.11 wireless channels in the 2.4 GHz range.

Checking the Windows Event Log for cache issues is the appropriate first step when troubleshooting a slow CAD workstation with RAID 10 and dual GPUs, as it can reveal hardware errors, driver problems, or cache-related performance issues without making system changes. The Event Log provides detailed information about system performance problems and hardware failures that could be affecting the workstation''s speed before attempting more invasive troubleshooting methods.
