IT Fundamentals FC0-U61 Syllabus Exam Questions Answers

Disk encryption is a type of encryption that protects the entire contents of a hard drive or a removable storage device by using a secret key to scramble the data. Disk encryption would best protect a laptop computer in the event of theft because it would prevent unauthorized access to the data on the laptop. Email, VPN, and HTTPS are not types of encryption that protect the entire contents of a laptop computer. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 8: Security Concepts, page 308.

A business continuity site is designed to ensure that business operations can continue in the event of a major disruption, such as a service outage. This availability concern is mitigated by having backup sites that can take over operations if the primary site is compromised or offline, ensuring that the organization remains functional.

B. Wiretapping and C. Eavesdropping are security concerns related to unauthorized access to communications.

Among the listed internet connection types, 'Fiber to the curb' (FTTC) generally provides the fastest speeds. FTTC involves running fiber-optic cables close to the curbs near homes or businesses, with the remaining connection to the premises being made through traditional coaxial or ethernet cabling. This provides higher speeds compared to traditional DSL (Digital Subscriber Line) or cellular connections.References: Networking and internet technologies, including different types of broadband connections, are thoroughly explored in CompTIA IT Fundamentals, emphasizing the speed and reliability differences among various internet access technologies.

 An if statement is a programming construct that is best to use when a program needs to choose among different options based on an input. An if statement evaluates a condition and executes a block of code if the condition is true. An if statement can also have an else clause that executes a different block of code if the condition is false. An if statement can also have multiple else-if clauses that check for additional conditions. For example, a program that chooses apples, oranges, or bananas based on an input could use an if statement like this:

A variable is a named memory location that can store a value, not a programming construct that can choose among options. A datatype is a classification of data that defines the possible values and operations for that data, not a programming construct that can choose among options. A comment is a remark or explanation in the source code that is ignored by the compiler or interpreter, not a programming construct that can choose among options.
