Authentic CompTIA Certification Exam FC0-U61 Questions Answers

 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. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 178.

A database is a collection of data that is organized and stored in a way that allows easy access, manipulation, and analysis. A database would be the best option for storing information for an application that needs to be accessed by concurrent users and store company information securely. A database can handle multiple user requests, enforce data integrity and security, and perform complex queries and operations on the data. A word processing document, a flat file, and a spreadsheet are not options that can support concurrent users, store company information securely, or perform complex operations on the data. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 5: Database Fundamentals, page 191.

The process of comparing MD5 values (hashes) after downloading software is primarily used to validate that the software source is legitimate and the file has not been altered or corrupted during download. MD5 is a widely used cryptographic hash function that produces a 128-bit hash value. By comparing the MD5 hash provided by the software distributor with the hash of the downloaded file, you can verify that the file is exactly what the distributor intended to deliver, without any modifications, whether malicious or accidental.
