CompTIA FC0-U61 Exam Questions

Adding more RAM to each workstation is the least expensive and most effective way to improve the performance of loading large files like a 2GB spreadsheet. RAM directly impacts how much data a workstation can hold in memory for fast access, and increasing it will help the spreadsheet load and process more quickly. Other options, like upgrading switches or moving to a shared database, may be more costly or less effective.

A . Buy faster networking switches may improve network speed but does not directly affect the local file processing speed.

B . Upgrade the operating system and applications may help, but adding RAM is typically a more cost-effective solution.

C . Move the file to a shared database is unnecessary for a single spreadsheet file.

DNS (Domain Name System) is used when a user types a webpage name (like www.example.com) into a browser's address field. DNS servers translate this domain name into the corresponding IP address so that the browser can load the appropriate website. This translation is essential for navigating the internet because web browsers communicate over IP addresses, not domain names. Reference: DNS is a fundamental network service discussed in CompTIA IT Fundamentals, which emphasizes its role in resolving human-friendly domain names to machine-readable IP addresses.

A variable is the best option to store a test score entered using a web form. In programming, variables are used to store data values that can change over time, such as user input. The variable can be set to store the score when the user submits it, allowing the program to manipulate or display the score later as needed. Reference: The use of variables for data storage and manipulation is a basic programming concept covered in CompTIA IT Fundamentals and other introductory programming courses.

The step that happens before establishing a theory of probable cause in the troubleshooting process is identifying the problem. This involves gathering information from the user, observing the symptoms, and systematically ruling out factors that may not be relevant. This step is crucial as it sets the foundation for developing an accurate theory of what might be causing the issue. Reference: Identifying the problem is part of the systematic approach to troubleshooting taught in CompTIA IT Fundamentals, which outlines a structured process for resolving IT issues.

A concurrent license would be most cost-effective for an organization where all users need access to software but not at the same time. Concurrent licenses allow a certain number of users to access the software simultaneously, regardless of who those users are. This type of licensing is efficient and economical for environments with variable software usage patterns. Reference: Licensing models and their applications are discussed in CompTIA IT Fundamentals, which includes various types of software licenses and their suitability for different organizational needs.
