FC0-U71 Is an example of a strong password? Practice Question

Which of the following is an example of a strong password?

⚠ Common exam trap

Watch out — candidates often choose passwords like 'abc123' or '123456' because they seem easy to remember, but the exam tests the understanding that a strong password must include a mix of character types and avoid common patterns or dictionary words.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Cr@zy8#s

(Cr@zy8#s) is correct because it meets all strong password criteria: it is at least 8 characters long, includes uppercase and lowercase letters, a digit, and special characters (@ and #). This complexity makes it resistant to brute-force attacks and dictionary attacks, as it increases the entropy and does not contain common words or sequential patterns.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    123456

    Why it's wrong here

    "123456" is a sequential numeric string occupying the top of every breached-credential list, so it succumbs instantly to brute-force and credential-stuffing attempts. Its appeal is memorability and fast entry on mobile keypads, but a strong password requires length and unpredictability, not a familiar keypad pattern.

  • ✓

    Cr@zy8#s

    Why this is correct

    Length plus mixed character classes drives brute-force resistance. "Cr@zy8#s" combines upper and lower case letters, digits and symbols, defeating dictionary and simple rule-based cracking attempts, whereas single-case words or short numeric strings fall quickly to automated guessing.

  • ✗

    abc123

    Why it's wrong here

    "abc123" combines a predictable alphabetic run with a sequential numeric suffix, both of which appear in standard cracking dictionaries, so it falls rapidly to rule-based attacks. It is tempting because it meets many complexity checkers superficially, yet length and true randomness — not character-class mixing alone — determine resistance to guessing.

  • ✗

    password

    Why it's wrong here

    The literal string "password" appears in every attacker wordlist and falls to a dictionary attack within seconds, so it cannot satisfy the complexity or length requirement. It is tempting because it is memorable and easy to type, which is precisely the property that makes a passphrase guessable rather than strong.
