The correct answer is implementing multi-factor authentication and enforcing password complexity requirements. These two practices work together because complexity rules—such as requiring a minimum length and a mix of character types—expand the effective keyspace, making brute-force and dictionary attacks far less feasible, while multi-factor authentication adds a separate verification layer that protects against credential theft or reuse even if a password is compromised. On the ISC2 Certified in Cybersecurity CC exam, this question tests your understanding of defense-in-depth authentication, often appearing as a “select two” item where a common trap is to choose password rotation alone instead of complexity. Remember the mnemonic “C-MFA” for Complexity and Multi-Factor Authentication—two pillars that directly reduce risk in corporate password management best practices.
ISC2 CC Security Operations Practice Question
This CC practice question tests your understanding of security operations. 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.
Which TWO of the following are best practices for password management in a corporate environment?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enforce password complexity requirements.
Option B is correct because enforcing password complexity requirements (e.g., minimum length, character types) reduces the risk of brute-force and dictionary attacks by increasing the effective keyspace. Option E is correct because multi-factor authentication (MFA) adds an additional layer of security beyond the password, mitigating credential theft or reuse. Together, they form a defense-in-depth approach to authentication security.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Store passwords in plaintext in a shared document.
Why it's wrong here
Plaintext storage is a major security risk.
✓
Enforce password complexity requirements.
Why this is correct
Complex passwords are harder to guess or crack.
Clue confirmation

✗
Prohibit password changes more than once per year.
Why it's wrong here
Periodic changes reduce risk from compromised credentials.
✗
Share passwords among team members for shared accounts.
Why it's wrong here
Sharing passwords increases risk of unauthorized access and loss of accountability.
✓
Implement multi-factor authentication.
Why this is correct
MFA adds an extra layer of security beyond passwords.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the misconception that frequent password changes improve security, but the CC exam expects candidates to know that NIST now recommends against mandatory periodic changes unless there is evidence of compromise, and that sharing passwords is never a best practice.
Detailed technical explanation
How to think about this question
Password complexity rules typically enforce a minimum of 8–12 characters and require at least three of four character types (uppercase, lowercase, digits, special characters). However, modern guidance (e.g., NIST SP 800-63B) emphasizes password length over complexity, as longer passphrases provide more entropy. MFA can be implemented via TOTP (RFC 6238), hardware tokens (FIDO2), or push notifications, and should be enforced for all administrative and remote access.

TExam Day Tips
→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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
