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

A trademark is the best option for a company to protect its logo. A trademark is a name, symbol, logo, or slogan that identifies a product or service and distinguishes it from others in the market. A trademark grants the owner the exclusive right to use the mark and to prevent others from using confusingly similar marks. A trademark can be registered with the appropriate authority to obtain legal protection and enforcement. A trademark can last indefinitely as long as it is used and renewed periodically. A trademark can also be indicated by the symbols ™ or ®. A copyright is not suitable for protecting a logo, as it only protects original works of authorship, such as books, music, movies, or software. A domain name is not suitable for protecting a logo, as it only identifies a website or an email address on the internet. A domain name can be registered with a domain name registrar to obtain exclusive use of the name for a certain period of time. A domain name can also be trademarked if it meets the criteria for trademark protection. A patent is not suitable for protecting a logo, as it only protects inventions or processes that are new, useful, and non-obvious. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 8: Software Development Concepts

A programmer uses DML to modify data in a database. DML stands for Data Manipulation Language, which is a subset of SQL (Structured Query Language) that is used to manipulate or change data in a database. DML includes commands or statements such as INSERT, UPDATE, DELETE, or MERGE, which can be used to add, modify, remove, or combine data in a table or structure within a database. DML can help a programmer to perform various operations or functions on the data in a database. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 143.

Optical drive and HDD are the examples of storage devices that have a spinning disk among the given options. A spinning disk is a component of a storage device that rotates at high speed to store and access data on its surface. A spinning disk is usually made of metal, glass, or plastic and coated with a magnetic material. A spinning disk has one or more read/write heads that move across the disk to read or write data on concentric tracks or sectors. An optical drive is a storage device that uses laser beams to read or write data on optical discs, such as CDs, DVDs, or Blu-ray discs. An HDD (hard disk drive) is a storage device that uses magnetic fields to read or write data on hard disks. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 38-39.
