DSL stands for Digital Subscriber Line, which is a type of broadband internet service that uses copper telephone cabling. A network technician installing an RJ11 connector, which is the standard connector for telephone lines, is most likely using DSL as the network connection type. Fiber, satellite, and cable are other types of internet service, but they use different connectors and cables than RJ11. References: CompTIA IT Fundamentals+ (Exam FC0-U61) Module 4 / Unit 2 / Connecting to a Network, page 6; CompTIA Network+ N10-008 Certification Study Guide, Chapter 2: Network Devices and Cabling, page 55.QUESTION NO: 230

When working with storage. 1,000,000MB can also be notated as:

A. 0.01PB.

B. 1TB.

C. 100GB.

D. 10,000,000KB.

Answer: B

 When working with storage, different units of measurement are used to express the amount of data. The most common units are bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). Each unit is equal to 1,000 of the previous unit, except for bytes, which are the smallest unit. Therefore, 1,000,000MB can also be notated as 1,000GB or 1TB. The other options are incorrect because they are either too large or too small to represent 1,000,000MB. For example, 0.01PB is equal to 10,000GB or 10TB, which is much larger than 1,000,000MB. Similarly, 100GB is equal to 100,000MB or 0.1TB, which is much smaller than 1,000,000MB. And 10,000,000KB is equal to 10,000MB or 0.01TB, which is also much smaller than 1,000,000MB. References:

CompTIA ITF+ Practice Test, question 230: “1TB is the correct answer.”

An array is the best choice for storing many integers in one container. An array is a data structure that can hold a fixed number of elements, which are all of the same data type. It is especially useful for storing a collection of data items at contiguous memory locations, allowing easy access to the elements using an index. Arrays are fundamental in programming for organizing data, allowing for efficient storage and quick access.

References: Arrays and their uses are basic concepts covered in programming fundamentals, frequently discussed in CompTIA IT Fundamentals and other introductory programming resources.

This pseudocode snippet correctly implements the requirement to apply a cost-of-living increase to employees making less than $15 per hour. By using a loop (For all employees in the list), it ensures that every employee meeting the condition (making less than $15 per hour) will have their salary adjusted by multiplying it by 1.032. This approach efficiently processes each relevant entry just once and applies the necessary increase accurately.

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.

Dumpster diving is a technique used by attackers to obtain sensitive information from discarded documents, such as passwords, account numbers, or personal details. This information can be used to breach the confidentiality of an organization or an individual. Confidentiality is the principle of protecting information from unauthorized access or disclosure. To prevent dumpster diving, documents containing confidential information should be shredded or securely disposed of. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 206.

 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.

Privacy expectations on a company intranet should be governed by the system usage agreements or acceptable use policies (AUPs) that employees are required to sign. These agreements outline the limits and expectations regarding employee privacy, use of the company's IT systems, and monitoring practices. Companies often make it clear that any data or activity on the intranet may be monitored, limiting personal privacy expectations in the workplace.

A. Precedents may influence policies, but privacy expectations are not based on them.

B. HR policy is more focused on employee relations and may reference IT policies, but it is not the primary document for setting IT privacy rules.

C. Word of mouth is not a reliable or enforceable method for establishing privacy expectations.

172.16.2.189 is a valid IP address that a technician can assign to a new desktop computer. An IP address is a unique identifier that is assigned to a device on a network that uses the Internet Protocol (IP). An IP address consists of four numbers separated by dots, each ranging from 0 to 255. For example, 192.168.1.1 is an IP address. An IP address can be classified into different classes based on the first number: Class A (1-126), Class B (128-191), Class C (192-223), Class D (224-239), and Class E (240-255). Each class has a different range of IP addresses that can be used for public or private networks. 172.16.2.189 is a Class B IP address that belongs to the private network range of 172.16.0.0 to 172.31.255.255. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 165.
