  D. Upgrading the current mesh network to support the 802.11 n specification

  Correct Answer: D

  When a WAP (Wireless Access Point) mesh network is experiencing a higher than anticipated amount of traffic, leading to degraded network service, upgrading the network to a more advanced wireless standard can help alleviate the problem. The 802.11n specification, also known as Wireless-N, offers significant improvements over earlier standards like 802.11b/g in terms of speed, range, and reliability. It allows for increased data throughput and better coverage, which can support a higher number of wireless users effectively. Upgrading to 802.11n: This involves replacing existing WAPs with those that support the 802.11n standard or higher. The upgrade can result in improved network performance by accommodating more wireless connections with higher data rates, reducing congestion and improving overall network efficiency. Replacing non-mobile users' laptops with wired desktop systems (A) could reduce wireless traffic but may not be feasible or desirable for all users. Increasing the wireless network adapter metric (B) would affect route priority but not overall network capacity. Adding wireless repeaters (C) can extend the range but might also introduce additional latency and does not necessarily increase the network's capacity to handle more users efficiently.

• Question 636:

  A user's Windows 10 workstation with an HDD is running really slowly. The user has opened, closed, and saved many large files over the past week. Which of the following tools should a technician use to remediate the issue?

  A. Disk Defragment

  B. Registry Editor

  C. System Information

  D. Disk Cleanup

  Correct Answer: A

  Over time, especially with frequent opening, modification, and saving of large files, a hard disk drive (HDD) can become fragmented. Fragmentation occurs when pieces of individual files are scattered across the disk, leading to longer read and write times, which can significantly slow down the computer. Disk defragmentation reorganizes these fragmented files, placing the pieces closer together on the drive, which improves access time and overall system performance. Disk Defragment: Using the Disk Defragment tool on a Windows 10 system with an HDD will help in reorganizing the data more efficiently, thus potentially remedying the slow performance issue. The Registry Editor (B) is a tool that allows for the viewing and editing of the Windows registry and is generally not used for performance improvement but rather for system settings and configuration adjustments. System Information (C) provides a detailed look at the computer's hardware and system details but does not offer tools for performance improvement. Disk Cleanup (D) can help free up space on the hard drive by removing temporary files and system files that are no longer needed, which can indirectly improve performance but is not the primary tool for addressing fragmentation.

• Question 637:

  A user's Windows desktop has low disk space. A technician thinks some upgrade files were never removed. Which of the following tools should the technician use to correct the issue?

  A. devmgmt.msc

  B. cleanmgr.exe

  C. dfrgui.exe

  D. diskmgmt.mac

  Correct Answer: B

  The correct tool to use for removing upgrade files and freeing up disk space on a Windows desktop is cleanmgr.exe, which stands for Disk Cleanup. Disk Cleanup is a maintenance utility included in Microsoft Windows designed to free up disk space on a computer's hard drive. The utility scans and analyzes the hard drive for files that are no longer of any use, and then removes the unnecessary files. It can delete temporary files, system files, empty the Recycle Bin, and remove a variety of system files and other items that you might no longer need.
