NEW QUESTION 1
Which of the following terms best describes the outcome of a text message that is encrypted from its original form?

• A. Cipher
• B. Vector
• C. Plain
• D. Algorithm

Answer: A

Explanation:
The outcome of a text message that is encrypted from its original form is best described as a cipher. A cipher is a text message that has been transformed into an unreadable or unintelligible form by using an encryption algorithm and a key. Encryption is the process of converting plain text into cipher text to protect the confidentiality, integrity, and authenticity of the message. A vector is not a term used in encryption, but it may refer to a data structure that can store multiple values of the same data type in an ordered sequence. Plain is not a term used in encryption, but it may refer to the original or unencrypted form of a text message. An algorithm is not the outcome of encryption, but it is the method or procedure that is used to perform encryption or decryption.

NEW QUESTION 2
A user is buying a laptop. The user will have a lot of personal and confidential information on the laptop. The user wants to ensure data cannot be accessed by anyone, even if the laptop is stolen. Which of the following should be set up to accomplish this?

• A. Encryption
• B. Compression
• C. Permissions
• D. Auditing

Answer: A

Explanation:
Encryption is the process of transforming data into an unreadable format using a secret key or algorithm. Encryption helps to protect the confidentiality and privacy of data, especially when it is stored on a device or transmitted over a network. Encryption can prevent unauthorized access to data by anyone who does not have the correct key or algorithm to decrypt it. For example, a user can encrypt the data on their laptop using a password or a biometric authentication method, so that even if the laptop is stolen, the data cannot be accessed by the thief56.

NEW QUESTION 4
An online retailer experienced an outage. An investigation revealed that the server received more requests than it could handle, and customers could not log in as a result. Which of the following best describes this scenario?

• A. Hardware failure
• B. Denial of service
• C. On-path attack
• D. Social engineering

Answer: B

Explanation:
The scenario where an online retailer experienced an outage because the server received more requests than it could handle and customers could not log in as a result is best described as a denial of service. A denial of service is a type of attack that aims to disrupt or prevent the normal functioning or availability of a system or network by overwhelming it with excessive traffic or requests. A denial of service can cause performance degradation, slowdown, or outage for the system or network and its legitimate users. A denial of service can be performed by a single attacker or a group of attackers using multiple compromised devices, which is called a distributed denial of service (DDoS). A hardware failure is not the scenario that describes the online retailer’s outage, but rather a possible cause or consequence of the outage. A hardware failure is a malfunction or breakdown of a physical component of a system or network, such as a disk, a memory, a CPU, a power supply, etc. A hardware failure can cause data loss, corruption, or interruption for the system or network and its users. A hardware failure can be caused by various factors, such as wear and tear, physical damage, overheating, power surge, etc. A hardware failure can also be induced by a denial of service attack that damages the hardware by overloading it. An on-path attack is not the scenario that describes the online retailer’s outage, but rather a type of network attack that involves intercepting or modifying data packets that are transmitted between two parties on a network. An on-path attack can compromise the confidentiality, integrity, or authenticity of the data or communication between the parties. An on-path attack can be performed by an attacker who has access to the same network segment or device as one of the parties, such as a router, a switch, or a hub. An on-path attack can also be performed by an attacker who tricks one of the parties into sending data to them instead of the intended destination, which is called a man-in-the-middle attack. A social engineering attack is not the scenario that describes the online retailer’s outage, but rather a type of attack that exploits human psychology and behavior to manipulate people into performing actions or revealing information that benefits the attacker. A social engineering attack can take various forms, such as phishing, vishing, baiting, quid pro quo, pretexting, or tailgating.

NEW QUESTION 8
A technician has successfully verified full system functionality after implementing the solution to a problem. Which of the following is the NEXT troubleshooting step the technician should do?

• A. Determine if anything has changed.
• B. Document lessons learned.
• C. Establish a theory of probable cause.
• D. Duplicate the problem, if possible.

Answer: B

Explanation:
Documenting lessons learned is the last step of the troubleshooting methodology, which is a systematic approach to solving problems. Documenting lessons learned involves recording the problem, the solution, and the process that was followed to resolve the problem. This can help prevent future occurrences of the same or similar problems, improve the troubleshooting skills of the technician, and provide a reference for other technicians who may encounter the same or similar problems. Documenting lessons learned would be the next troubleshooting step the technician should do after verifying full system functionality. Determining if anything has changed, establishing a theory of probable cause, and duplicating the problem are not steps that follow verifying full system functionality in the troubleshooting methodology.

NEW QUESTION 9
Which of the following is both an input and output device?

• A. Microphone
• B. Speaker
• C. Touch-screen monitor
• D. Keyboard

Answer: C

Explanation:
A touch-screen monitor is a device that can function as both an input and output device. An input device is a device that allows users to enter data or commands into a computer or system. An output device is a device that displays or produces data or information from a computer or system. A touch-screen monitor can function as an input device by detecting the touch or gesture of the user on the screen and sending the corresponding signal to the computer or system. A touch-screen monitor can also function as an output device by showing visual information on the screen. A microphone, a speaker, and a keyboard are not devices that can function as both an input and output device. A microphone is an input device that allows users to record sound or voice into a computer or system. A speaker is an output device that plays sound or voice from a computer or system.
A keyboard is an input device that allows users to type text or characters into a computer or
system. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 3: Computing Components, page 106.

NEW QUESTION 10
Which of the following is an example of an interpreted language?

• A. C++
• B. Java
• C. Python
• D. Go

Answer: C

Explanation:
Python is an example of an interpreted language, which is a type of programming language that does not need to be compiled before execution. Instead, an interpreter program translates and executes the source code line by line at run time. Interpreted languages are usually easier to write and debug, but slower to execute than compiled languages. C++ and Java are examples of compiled languages, which are types of programming languages that need to be translated into executable machine code by a compiler program before execution. Compiled languages are usually faster to execute but harder to write and debug than interpreted languages. Go is an example of a hybrid language, which is a type of programming language that combines features of both compiled and interpreted languages. Hybrid languages use an intermediate code that can be executed by a virtual machine or an interpreter at run time.

NEW QUESTION 11
Which of the following is a reason why complex passwords are required?

• A. To encourage password variety
• B. To prevent someone from guessing them
• C. To make them harder to remember
• D. To reduce social engineering attacks

Answer: B

Explanation:
A managed relational database is a type of database that is hosted and maintained by a cloud service provider such as Microsoft Azure or Amazon Web Services. A relational database is a type of database that organizes data into tables that are related to each other by common fields or attributes. A managed relational database would be the best option for allowing multiple users to create and edit reports at the same time because it can handle concurrent user requests, provide high availability and scalability, and perform complex queries and operations on the data. A text file on a shared drive, an informational intranet page, and locally installed productivity software are not options that can allow multiple users to create and edit reports at the same time because they cannot handle concurrent user requests, provide high availability and scalability, or perform complex queries and operations on the data.

• A. QUESTION NO: the obvious.
• B. Divide and conquer.
• C. Duplicate the problem
• D. Research the knowledge base.

Answer: B

Explanation:
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. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 9: Troubleshooting Methodology, page 332.

NEW QUESTION 13
Which of the following can a company use to protect its logo?

• A. Trademark
• B. Copyright
• C. Domain name
• D. patent

Answer: A

Explanation:
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.
