FC0-U71 Exam Dumps - CompTIA Tech+ Certification Exam

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), one of the five critical steps when configuring a wireless router is to change the administrator username and password:

“The Wi-Fi Alliance lists five critical keys to setting up a secured wireless router:

Change the router’s SSID.

Change the administrator username and password. Make sure that it’s a strong password.

Enable WPA3 or WPA2 Personal.

Choose a strong security passphrase.

Connect clients using the same security mode.”

This ensures unauthorized users cannot log in to the router’s settings.

The largest unit is determined by converting all values to the same unit:

2TB = 2,000GB

100GB = 100GB

4,000MB = 4GB

50KB = 0.00005GB

Thus, 2TB is the largest. As described in the CompTIA ITF+ FC0-U71 Study Guide:

“Data storage capacity is measured using standard units such as KB, MB, GB, and TB, where 1TB = 1,000GB.”

Meaningful reporting refers to the process of analyzing and summarizing data into actionable insights to support business decisions.

“Reports generated from data analytics provide meaningful insights to support strategic decision-making by company leadership.” — CompTIA ITF+

Correct answer: A

Data at rest refers to information stored on a device or disk, such as a hard drive. The encryption that protects it is typically file-level encryption (or full-disk encryption).

“File-level encryption applies encryption to individual files or directories on storage media and is used to protect data at rest.” — CompTIA ITF+ Study Guide

VPN and HTTPS protect data in transit.

Plaintext means data is unencrypted, and therefore is not protective.

Therefore, A is the correct answer.

In the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the section on wireless encryption options explains:

“Exam objective 6.5 specifies that you should know Wi-Fi encryption options such as an open network, preshared key, WPA, WPA2, and WPA3… Focus on understanding that open networks are unsecure, and that WPA3 is better than WPA2, which is better than WPA.”

Further, it describes open networks as:

“Open portals pose security risks to the network and to users on the network. Use them with caution.”

Therefore, to allow anyone in the community to connect freely, the router must be set to Open (no password or encryption).
