CompTIA CompTIA Tech+ FC0-U71 New Questions

Encryption protects data by encoding it, so it can only be accessed or read by someone with the proper key or password. It ensures confidentiality during file transfers over insecure networks like the internet.

“Encryption is used to protect data in transit, ensuring that only authorized parties can read the content during transmission.” — CompTIA ITF+ Security Essentials

Correct answer: C

RAM allows multiple applications to run simultaneously. Insufficient RAM causes performance drops:

“When several applications are open, the system relies heavily on RAM for temporary storage of active processes.”

Storage, motherboard, or NIC do not directly handle temporary application memory while multitasking.

The correct answer is C. Onboard NICs are built into the motherboard. An onboard NIC is integrated into the motherboard, while an expansion card NIC is a separate add-on card installed into an expansion slot. The question asks for the primary difference, not speed or cost. Onboard does not automatically mean faster or more expensive.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that Tech+ objective 2.2 expects knowledge of “wired and wireless cards as well as onboard (integrated into the motherboard) versus expansion cards.” It also explains that “most computers today have the NIC circuitry integrated into their motherboards.”

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines phishing as:

“Creating a site or sending an email that masquerades as a legitimate secure site but actually steals your information is called phishing.”

It further explains:

“When people talk about phishing, it’s generally in the context of suspicious email because that’s how the term originated. Hackers sent out messages hoping to get someone to take the bait.”

By deleting a suspicious email without opening or clicking links, the user is practicing anti-phishing awareness — a key cybersecurity best practice.
