The answer is that the 'operator' username uses a password instead of a secret, creating a critical security issue. When you configure a username with the 'password' keyword on a Cisco device, the credential is stored in plaintext or with weak reversible encryption (Type 7) in the running configuration, making it easily readable if the config is captured or viewed. In contrast, the 'secret' keyword, as used for the 'admin' user, stores the password using a strong hash like MD5 (Type 5) or SHA-256 (Type 8/9), which is far more secure. This question tests your understanding of the Username Secret vs Password Security distinction on the CCNP ENARSI 300-410 exam, often appearing in device management and secure access topics. A common trap is assuming both keywords offer equal protection, but the exam expects you to recognize that 'password' is inherently insecure. Memory tip: "Secret is secure, password is plain—always use secret to keep credentials from being seen."
300-410 Device Access Control Practice Question
This 300-410 practice question tests your understanding of device access control. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'operator' username uses a password instead of a secret, which is stored insecurely in the configuration.
Option A is correct because the 'operator' username uses a 'password' keyword instead of 'secret', which means the password is stored in plaintext (or weakly hashed) in the running configuration. Cisco recommends using 'secret' with a strong hash algorithm (e.g., MD5 or SHA-256) to protect credentials from being easily compromised if the configuration is viewed. This is a direct violation of secure device access best practices.
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.
✓
The 'operator' username uses a password instead of a secret, which is stored insecurely in the configuration.
Why this is correct
The 'password' keyword stores the password in a reversible format (type 7 or clear), whereas 'secret' uses MD5 hashing.
Related concept
Read the scenario before looking for a memorised answer.
✗
The 'admin' user has privilege 15, which is too high for administrative access.
Why it's wrong here
Privilege 15 is appropriate for full administrative access.
✗
The console line is missing the 'transport input' command.
Why it's wrong here
Console typically does not require 'transport input'; it's for VTY lines.
✗
The VTY lines should use 'login' without 'local' to allow remote authentication.
Why it's wrong here
'login local' is correct for local database authentication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between 'password' and 'secret' in username configurations, and the trap here is that candidates may overlook the security implications of using 'password' instead of 'secret' for non-privileged users, assuming it only matters for enable passwords.
Detailed technical explanation
How to think about this question
When a Cisco device uses 'password' under a username, the password is stored using a Type 7 (Vigenère cipher) or Type 0 (plaintext) encoding, both of which are trivially reversible. In contrast, 'secret' uses Type 5 (MD5 hash) or Type 8/9 (SHA-256) hashing, which provides cryptographic protection. In real-world scenarios, an attacker who gains access to the running configuration (e.g., via SNMP or a misconfigured backup server) can easily extract Type 7 passwords using free online tools, while hashed secrets remain computationally expensive to crack.

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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
