Important CompTIA FC0-U71 Exam Questions

Answer: A

Explanation:

A password reuse policy prevents users from using the same password across multiple platforms or reusing previously used passwords. This is a best practice to reduce the risk of credential stuffing attacks.

''Password reuse policies help ensure users do not reuse old or existing passwords across multiple platforms, reducing exposure from compromised accounts.'' --- CompTIA ITF+ Security Objectives

Correct answe r: A

Answer: C

Explanation:

Web browsers store cached data to improve loading speeds and remember form inputs. If outdated credentials are appearing, clearing the cache ensures that old stored data is removed and the page loads fresh content.

''Cached data can include stored form data, which may result in outdated information being auto-filled. Clearing the browser cache resolves this.'' --- CompTIA ITF+ Official Curriculum

Correct answe r: C

Answer: C

Explanation:

A GPU (Graphics Processing Unit) is a specialized processor designed to perform calculations related to rendering images and videos. It's an example of a processing component.

''The GPU is a processor dedicated to graphical computations and image rendering, assisting or replacing the CPU in handling visual data.'' --- CompTIA ITF+ Hardware Essentials

Correct answe r: C

Answer: A

Explanation:

The correct answer is A. Remove unnecessary software. Removing software that is not needed is a device-hardening step. Unnecessary applications can increase the attack surface of a laptop, so removing them helps reduce vulnerabilities. Installing drivers may be required for hardware functionality, but it is not the best security improvement. Configuring backups helps with recovery, but it does not directly harden the device. Benchmark testing measures performance, not security.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that device hardening makes a device harder to exploit and includes ''removing or disabling unused software and services.'' The guide's Chapter 11 lab also lists the task ''Remove unwanted, unnecessary, or malicious software.''

Answer: A

Explanation:

The correct answer is A. Unnecessary. The key phrase is ''already handled natively by the OS.'' Since the operating system already provides Wi-Fi settings management, the extra software is redundant and not required. It is not necessarily malicious, because the question does not say it is harmful. It is not best described as open-source, because licensing is unrelated to whether the software should be removed. ''Unwanted'' could describe software the user does not want, but ''unnecessary'' is more precise because the reason for removal is that the OS already performs the same function.

Exact Extract/Reference: The Tech+ Study Guide lists ''Removal of software'' and specifically includes ''Unwanted,'' ''Unnecessary,'' and ''Malicious'' software under software/security best practices. The guide also states that removing an application can free disk space and memory, and that Tech+ objective 6.2 expects knowledge of removing unwanted, unnecessary, and malicious software.
