FC0-U71 Exam Dumps - CompTIA Tech+ Questions and Answers

The CompTIA Tech+ Study Guide discusses social engineering prevention:

“Social engineering relies on manipulating people rather than technology. The best protection against social engineering is user awareness and verifying identity before sharing information.”

Verifying a user’s identity via a phone call before taking any action (such as password reset or data access) is an essential safeguard against impersonation attempts.

A primary key is a unique identifier for each record in a database table. It must be unique and not null across all rows. In this table, the field ID is the only column that uniquely identifies each row and does not repeat.

“A primary key is a field (or a set of fields) that uniquely identifies a record in a table. It ensures that each record can be uniquely retrieved.” — CompTIA ITF+ Official Study Guide

Analysis of other options:

Month, Day, Year, and Name can have duplicate values across multiple records and therefore do not serve as unique identifiers.

Correct answer: A

The ID field contains unique values for each record and is typically used as a primary key in a database. A primary key uniquely identifies each row in a table.

Month, Day, Year, and Name may have duplicates and do not guarantee uniqueness.

The CompTIA Tech+ Study Guide explains:

“Remote support software allows technicians to connect to a user’s computer from another location, troubleshoot issues, install applications, and perform updates without physically being at the same site.”

Additionally, the review question section confirms:

“You are setting up a technical support help desk for a new app. What type of software should you get to help the technicians fix problems more effectively?

Answer: Remote support.”

Thus, the technician in another state uses remote support software to perform the installation.

A loop is a programming construct that repeats a set of instructions while a condition is true. This is used to automate repetitive tasks in code.

“Loops are used in programming to execute the same block of code multiple times under specific conditions.” — CompTIA ITF+ Programming Concepts

Correct answer: A

The web browser history stores records of websites that a user has visited. This is typically the most straightforward and accessible method for determining whether users accessed inappropriate or unauthorized online content. The CompTIA ITF+ documentation explains:

“Web browsers maintain a history of visited URLs, which can be used for monitoring and auditing user activity, including detecting policy violations regarding internet usage.”

System logs are broader and generally capture system or security events.

Cookies store session and tracking data but don’t always show what content was accessed.

Location tracking helps with geolocation, not content monitoring.

Therefore, the correct choice is D.

Account logs provide details about authentication attempts and can confirm whether a user successfully logged in or was denied access.

“Authentication events are recorded in system and application logs, helping verify login success or failure.” — CompTIA ITF+ Security Concepts

Correct answer: A

A VPN (Virtual Private Network) creates a secure, encrypted connection over the internet between the user and a remote network, enabling secure access from home or public networks.

“VPNs provide a secure tunnel for transmitting data over unsecured networks, such as the internet, by encrypting all traffic between the client and the network.” — CompTIA ITF+ Security Topics

Other options:

A. LAN – Local and not for remote use

B. FTP – Transfers files but lacks modern encryption

C. DNS – Resolves domain names, not for access

Correct answer: D

The CompTIA Tech+ Study Guide explains:

“For a table in a database to be relational, it must have a primary key. In fact, its creation is mandatory when a table is created. A primary key is one or more fields whose data is used to identify a record uniquely.”

It further adds:

“Primary keys for tables are stored in an index, which enforces the uniqueness requirement.”

Hence, the unique identifier for records in a relational database is the primary key.

The correct answer is A. To present identical content on multiple displays. Display mirroring is used when the same screen image must appear on more than one display, such as a laptop screen and a projector in a conference room. This is useful for presentations because the audience sees the same content the presenter sees. Mirroring does not improve cloud speed, add security by itself, or share files from network-attached storage.

Exact Extract/Reference: The Tech+ Study Guide explains that when “two or more displays are used at the same time to project the same image, that is called mirroring.” It also states that “all actions performed on one display” are shown on the mirrored display.

This scenario describes a situation where a user has already successfully logged into the system (i.e., has been authenticated) but cannot access a particular network resource (the shared folder). This falls under the concept of authorization, which determines what actions or resources a user is permitted to access after authentication.

“Authorization is the process of granting or denying access to network resources once the user has been authenticated.” — CompTIA ITF+ Official Study Guide

Authentication verifies the identity of the user (e.g., username and password).

Authorization controls access rights (e.g., shared folders, files).

Accounting tracks user activity (e.g., audit logs).

Non-repudiation ensures actions or transactions cannot be denied later.

Therefore, the correct answer is B: Authorization.
