CompTIA FC0-U61 CompTIA IT Fundamentals+ Certification Exam Practice Test

Answer : A

WPA2 (WiFi Protected Access II) is a WiFi security option that uses encryption and authentication to protect the wireless network from unauthorized access or eavesdropping. WPA2 is the most secure and recommended WiFi security option among the options given. If some light switches are no longer communicating after replacing the wireless router with a new device that uses WPA2, the most likely cause is that the light switches do not support WPA2. The light switches may need to be updated or replaced to be compatible with WPA2. The router operating on a different channel, the key not meeting password complexity requirements, and the SSID not being broadcast are not likely causes of the light switches not communicating after replacing the wireless router with a new device that uses WPA2.Reference: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 311.

Answer : D

Ann's IP-based security camera requires an Internet connection and a wireless router to function properly. The camera has an LED light indicating it has power, which means it is not malfunctioning due to the power interruption. However, the power interruption may have affected Ann's Internet connection and wireless router, which are still down. This would prevent the camera from communicating with the network and the cloud service that stores the video footage.Reference: The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 178.

Answer : B

Divide and conquer is a troubleshooting methodology that involves breaking down a complex problem into smaller and more manageable parts, and then testing each part to isolate the cause of the problem. QUESTION NO : the obvious, duplicate the problem, and research the knowledge base are not troubleshooting methodologies that involve dividing the problem into smaller parts.Reference: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 9: Troubleshooting Methodology, page 332.

Answer : B

RAM (Random Access Memory) on a desktop computer is typically measured in gigabytes (GB). RAM is a critical component of a computer's performance, as it temporarily stores data that the CPU uses for processing tasks. The use of gigabytes (GB) as a unit of measurement for RAM has become standard as modern computing demands have increased. RAM sizes generally range from 4 GB to 32 GB or more in typical desktop computers, depending on the system's requirements.

TB (terabytes) is usually used to measure storage devices like hard drives or SSDs, where large quantities of data are stored permanently.

MB (megabytes) and KB (kilobytes) are smaller units of measurement and were more commonly associated with RAM in older computer systems, but modern systems have exceeded the need for these smaller denominations for memory.

Answer : C

A locally stored word processing document would have the highest expectation of privacy among the given options. Privacy is the right or ability of individuals or groups to control or limit the access or disclosure of their personal information by others. A locally stored word processing document is a file that contains text, images, or other data that is created and saved on a device's internal storage, such as a hard drive or SSD. A locally stored word processing document can have a higher level of privacy than a file that is shared, uploaded, or transmitted over the Internet or a network, because it is less exposed to potential threats or breaches. However, a locally stored word processing document may still require additional security measures, such as encryption, password protection, or backup, to ensure its privacy and integrity.Reference: The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 205.

Answer : A

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.

Answer : C

1.22Gbps would be the fastest transfer rate when transferring a file across the network among the given options. A transfer rate is a measure of how much data can be transmitted or received over a network in a given time. A transfer rate is usually expressed in bits per second (bps) or its multiples, such as Kbps (kilobits per second), Mbps (megabits per second), or Gbps (gigabits per second). A higher transfer rate means faster data transmission or reception. 1.22Gbps is equivalent to 1,220Mbps, which is higher than 110Mbps, 123Mbps, or 1001Kbps.Reference: The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 164.
