 x86 only supports an installation on a 32-bit CPU architecture is the statement that best represents what the “…x86.exe” means in the installation file. x86 is a term that refers to a family of processors or instruction sets that use 32-bit registers and memory addresses. x86 processors can only run software applications that are compatible with the 32-bit architecture. An installation file that has the suffix “…x86.exe” indicates that the file is an executable file that can only be installed on a 32-bit system. A 64-bit system can run both 32-bit and 64-bit applications, but a 32-bit system can only run 32-bit applications. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 34.

The best solution for the technician to resolve the issue quickly is to add an access point for the users. An access point is a device that provides wireless connectivity to the network. An access point can be connected to a wired network and extend its coverage to wireless devices, such as laptops, smartphones, or tablets. By adding an access point on the west side of the building, the technician can enable the users’ laptops to connect to the internet wirelessly without changing their hardware or software settings. Adding a switch and hardwiring the users’ laptops is not a quick solution, as it would require installing cables and configuring the network settings on each laptop. Adding a network router is not necessary, as a router is a device that connects multiple networks and routes traffic between them. A router does not provide wireless connectivity by itself, unless it has a built-in access point. Replacing the users’ laptops with desktop computers is not a feasible solution, as it would incur high costs and inconvenience for the users. References: CompTIA IT Fundamentals (ITF+) Study Guide: Exam FC0-U61, Second Edition, Chapter 3: Infrastructure, pages 90-91

Single-factor authentication is a method of verifying a user’s identity by using only one piece of information, such as a username and password. Biometrics, multifactor authentication, and least privilege are not examples of single-factor authentication. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 304.

IOPS (Input/Output Operations Per Second) is a term that refers to the performance of a storage device or system. It measures how many read and write operations can be performed by the storage device or system in one second. IOPS would best apply to the operating system function of disk management, which involves managing how data is stored, accessed, and organized on disks. Process management, application management, and service management are not operating system functions that directly relate to IOPS. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 4: Programming Concepts and Data Structures, page 158.
