Tablets typically connect to wireless networks using Wi-Fi, which adheres to the IEEE 802.11 standard (often seen as 802.11a/b/g/n/ac/ax). The correct protocol family for this type of connection is802.11X(referring to Wi-Fi technologies broadly).

“Wireless devices such as tablets use the 802.11 standards to connect to Wi-Fi access points for network connectivity.” — CompTIA ITF+

Other options:

B. Thunderbolt and D. USB-C – Wired connection standards

C. Bluetooth – Short-range peripheral communication, not Wi-Fi

Correct answer: A

If a USB port isdisabledin the BIOS or device manager, the system won’t detect devices connected to it. This is the most likely cause if nothing happens when a USB device is inserted.

“Hardware ports can be disabled via firmware settings or device policies, which prevents detection of peripherals.” — CompTIA ITF+ Hardware Troubleshooting

Correct answer: A

CPU speed is measured inmegahertz (MHz)orgigahertz (GHz), indicating how many million or billion cycles the processor can execute per second.

“CPU performance is commonly measured in megahertz (MHz) or gigahertz (GHz), representing the processor’s clock speed.” — CompTIA ITF+

MB is for memory/storage size.

Mbps is for network speed.

MAC is a hardware address, not a performance metric.

Correct answer: A

Pop-up blockers prevent new windows or tabs from opening, which can block reports that open in pop-up windows:

“If a web page uses pop-up windows to present information, a pop-up blocker may prevent the new content from loading.”

Cache clearing, accessibility options, or private browsing don’t directly affect hyperlink behavior.

When a new vulnerability is discovered in software, thebest way to secure itis byapplying updates (patches)released by the software vendor. According to the CompTIA ITF+ objectives:

“Vendors regularly release software updates and security patches to fix vulnerabilities that could be exploited by attackers. Installing these patches promptly is crucial for maintaining system security.”

Although configuring a firewall and authentication improves overall security, they do not directly patch or fix the vulnerability. Uninstalling may be an option only if a patch is unavailable or the software is no longer needed. Therefore, the best and most proactive response is B: Apply updates.

Personally Identifiable Information (PII)refers to any data that can be used to identify an individual uniquely.Full nameanddate of birthare classic examples of PII.

“PII includes data such as names, birth dates, Social Security numbers, and other information that can directly or indirectly identify a person.” — CompTIA ITF+ Security Essentials

Correct answers: A and B

Aprinteris anoutputdevice because it receives digital data from a computer and converts it into a printed physical format (such as paper).

“Output devices display or reproduce information from the computer. Examples include monitors, speakers, and printers.” — CompTIA ITF+ Fundamentals

Correct answer: B
