FC0-U61 Exam Dumps - CompTIA IT Fundamentals Questions and Answers

 A mobile phone is the most likely device that is causing this message, because it can be plugged into a USB port for charging or data transfer, and then unplugged when the user leaves the workstation. A mobile phone may also not be detected by the file audits, as it may not have any files stored on the workstation or may use encryption or password protection. A mouse, a scanner, and an external hard drive are less likely to be plugged and unplugged frequently, and they would also leave traces of their presence in the file audits or device manager. References: CompTIA IT Fundamentals+ FC0-U61 Cert Guide, Chapter 3: Device Ports and Peripherals, page 77; CompTIA IT Fundamentals+ (Exam FC0-U61) Module 4 / Unit 2 / Connecting to a Network, page 6; How to identify USB Ports in Device Manager?

Float is a data type that can store decimal or fractional numbers, such as 3.14, 0.5, or -2.75. Float would be the best data type to use for storing monetary values because monetary values often involve decimals, such as $1.99, 0.25,or-5.50. Integer is a data type that can only store whole numbers, such as 1, 0, or -2. Integer would not be suitable for storing monetary values that have decimals. The other options are not data types that can store numerical values.

The pseudocode given in the question is a program that assigns different values to the variable NAME based on the values of the variables TIME and DATE. The program starts by initializing the variables NAME, TIME, and DATE with empty strings, “NOON”, and “Monday” respectively. Then, it uses two nested IF-ELSE statements to check the values of TIME and DATE and modify the value of NAME accordingly. The first IF-ELSE statement checks if TIME is equal to “NOON”. If it is, it sets NAME to “foo”. If it is not, it checks if TIME is equal to “MIDNIGHT”. If it is, it sets NAME to “bar”. If it is not, it does nothing. The second IF-ELSE statement checks if DATE is equal to “Monday”. If it is, it concatenates “sad” to the end of NAME. If it is not, it checks if DATE is equal to “Friday”. If it is, it concatenates “happy” to the end of NAME. If it is not, it does nothing. Finally, the program prints the value of NAME. Since the values of TIME and DATE are “NOON” and “Monday” respectively, the program will set NAME to “foo” in the first IF-ELSE statement and then add “sad” to it in the second IF-ELSE statement. Therefore, the output of the program will be “foosad”. References: CompTIA IT Fundamentals (ITF+) Certification Guide, pages 216-217. Pseudocode - Designing an algorithm - KS3 Computer Science … - BBC.

Setting a BIOS password is a security-related best practice that would prevent end users from booting alternative operating systems on workstations. A BIOS password restricts access to the BIOS settings, which control the boot order and other hardware configurations of the computer. Installing a host-based firewall, patching the operating system, and removing unnecessary software are also security-related best practices, but they do not directly prevent booting alternative operating systems on workstations. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 7: Security Concepts1

 x86 only supports an installation on a 32-bit CPU architecture is the statement that best represents what the “…x86.exe” means in the installation file. x86 is a term that refers to a family of processors or instruction sets that use 32-bit registers and memory addresses. x86 processors can only run software applications that are compatible with the 32-bit architecture. An installation file that has the suffix “…x86.exe” indicates that the file is an executable file that can only be installed on a 32-bit system. A 64-bit system can run both 32-bit and 64-bit applications, but a 32-bit system can only run 32-bit applications. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 34.

The concept of a database record is best described as a collection of fields about the same object. A database record is a row in a table that represents an instance of an entity, such as a customer, an order, a product, etc. A database record consists of one or more fields that store data about the attributes of the entity, such as name, address, phone number, quantity, price, etc. A database record can be uniquely identified by a primary key, which is a field or a combination of fields that do not repeat in the table. A collection of rows, columns, and constraints is not the concept of a database record, but rather the concept of a database table. A database table is a structure that organizes data into rows and columns. Each row represents a record, and each column represents a field. A database table can have constraints that define the rules and restrictions for the data in the table, such as primary keys, foreign keys, unique keys, check constraints, etc. A collection of schemas within the same database is not the concept of a database record, but rather the concept of a database instance. A database instance is a set of memory structures and processes that manage and access a database. A database instance can contain one or more schemas, which are collections of objects that belong to a user or an application in the database, such as tables, views, indexes, etc. A collection of tables within different schemas is not the concept of a database record, but rather the concept of a database relationship. A database relationship is a connection between two tables that share common data. A database relationship can be established by using foreign keys, which are fields that reference the primary keys of another table. A database relationship can be one-to-one, one-to-many, or many-to-many depending on how many records in each table are related to each other. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 6: Database Fundamentals

 TLS (Transport Layer Security) is a protocol that should be enabled to reduce the risk of a MITM (man-in-the-middle) attack. A MITM attack is a type of cyberattack where an attacker intercepts and alters the communication between two parties without their knowledge. A MITM attack can compromise the confidentiality, integrity, and authenticity of the data being transmitted. TLS is a protocol that provides encryption, authentication, and integrity for data communication over the Internet. TLS can prevent a MITM attack by encrypting the data to make it unreadable by the attacker, authenticating the identities of the parties to prevent impersonation, and verifying the integrity of the data to detect any tampering. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 206.

Password reuse is the practice of using the same password for multiple accounts or services. Password reuse would increase the risk of account security on other sites if a large payment website was breached recently. If the attackers obtained the user’s password from the breached website, they could try to use it to access the user’s accounts on other sites. Password reuse should be avoided and different passwords should be used for different accounts or services. Password history, password expiration, and password age are not password best practices that would mitigate this risk. Password history is the record of previous passwords that a user has used for an account or service. Password expiration is the time limit for using a password before it needs to be changed. Password age is the length of time that a password has been in use. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 308.

 A UPS (uninterruptible power supply) provides protection against power outages by providing backup power to connected devices in case of a power failure. A UPS typically consists of a battery, an inverter, and a surge protector. A UPS can prevent data loss, hardware damage, or downtime caused by sudden loss of electricity. A UPS can also protect against power surges, spikes, or fluctuations that can harm electronic devices.

A denial of service (DoS) is a cyberattack that attempts to disrupt the normal functioning of a network or system by overwhelming it with traffic or requests. A UPS does not provide protection against DoS attacks, as they target the network layer, not the physical layer. A replay attack is a cyberattack that involves intercepting and retransmitting data to impersonate or deceive another party. A UPS does not provide protection against replay attacks, as they target the application layer, not the physical layer. Wiretapping is the act of secretly monitoring or recording the communication or data transmission of another party. A UPS does not provide protection against wiretapping, as it does not encrypt or secure the data.
