The answer is verifying digital signatures, reading user reviews, and checking hash values. These three practices work together to verify software legitimacy before installation because digital signatures confirm the publisher’s identity and that the code hasn’t been tampered with, while hash values like SHA-256 provide cryptographic integrity by matching the file against the vendor’s published digest. User reviews add a social layer, often revealing community reports of malware or tampering that technical checks might miss. On the CompTIA ITF+ FC0-U61 exam, this question tests your understanding of layered security verification, and a common trap is choosing only one method—like just reading reviews—while ignoring cryptographic checks. Remember the mnemonic “DHR” for Digital signatures, Hash values, and Reviews to recall the three pillars of safe installation.
FC0-U61 Applications and Software Practice Question
This FC0-U61 practice question tests your understanding of applications and software. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user wants to ensure software is legitimate and free from malware before installation. Which THREE of the following are recommended practices?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Read user reviews and check hash values
Option B is correct because reading user reviews can reveal community reports of malware or tampering, and checking hash values (e.g., SHA-256) against the vendor's published digest verifies file integrity, ensuring the software hasn't been altered. This combination provides both social and cryptographic verification of legitimacy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Use a cracked version to save money
Why it's wrong here
Cracked software often contains malware and violates copyright.
✓
Read user reviews and check hash values
Why this is correct
Reviews and hash comparisons help verify legitimacy.

✗
Disable antivirus to speed up installation
Why it's wrong here
Disabling antivirus increases vulnerability.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think disabling antivirus speeds up installation without realizing it removes a critical security layer, or they might confuse 'cracked version' with a legitimate free trial, missing that cracking inherently bypasses integrity checks.
Detailed technical explanation
How to think about this question
Hash verification relies on cryptographic hash functions like SHA-256, which produce a fixed-size digest unique to the file; even a single bit change yields a completely different hash. Digital signatures (Option D) use public-key cryptography (e.g., RSA or ECDSA) to authenticate the publisher and ensure the code hasn't been tampered with, as the signature is verified against the vendor's certificate. In practice, a user might download a tool like Gpg4win to verify GPG signatures, or use built-in OS tools like certutil -hashfile on Windows.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
