CompTIA FC0-U61 Exam Actual Questions

The 802.11ac standard supports higher data rates, improved capacity, and better performance in dense environments. It offers significant improvements over previous standards like 802.11a, 802.11b, 802.11g, and 802.11n, with support for speeds up to several gigabits per second under optimal conditions. For a range of 115ft indoors and a speed of 700Mbps, 802.11ac is the most suitable choice due to its enhanced capabilities to handle higher speeds and greater ranges than its predecessors. Reference: Details about various Wi-Fi standards including their range and speed capabilities are covered in IT certifications such as CompTIA Network+ and are essential knowledge for IT professionals.

Personally Identifiable Information (PII) refers to data that can be used to identify, contact, or locate a single person, or to identify an individual in context. A full name and date of birth are classic examples of PII because they can directly identify a person. Other options listed may relate to a person's life but do not specifically and directly identify an individual in most contexts. Reference: The definition and examples of PII are part of data privacy topics covered under the CompTIA IT Fundamentals, which discusses security measures and identification data types.

To free up space on an HDD without deleting files, using the operating system's compression feature is the best approach. Compression reduces the size of files on the disk by using algorithms to minimize the space they take up, thus freeing up storage capacity while keeping the files accessible. Reference: File system management, including the use of compression to optimize storage, is a topic discussed in the CompTIA IT Fundamentals, which also covers system utilities and management practices.

Among the listed internet connection types, 'Fiber to the curb' (FTTC) generally provides the fastest speeds. FTTC involves running fiber-optic cables close to the curbs near homes or businesses, with the remaining connection to the premises being made through traditional coaxial or ethernet cabling. This provides higher speeds compared to traditional DSL (Digital Subscriber Line) or cellular connections. Reference: Networking and internet technologies, including different types of broadband connections, are thoroughly explored in CompTIA IT Fundamentals, emphasizing the speed and reliability differences among various internet access technologies.

The best security method for employees who use their own devices for work is to keep the device software updated. Regular software updates include security patches that address vulnerabilities, reducing the risk of exploits. This preventative measure is crucial for maintaining the security integrity of not only the individual devices but also the corporate network they connect to. Reference: Mobile and device security, including the importance of software updates, is covered in CompTIA IT Fundamentals, highlighting the best practices for securing devices used in a corporate environment.
