- A
SNMPv3 supports authentication and encryption for secure network monitoring.
SNMPv3 includes security features such as authentication (MD5/SHA) and encryption (DES/AES) to protect data in transit.
- B
SNMPv2c uses community strings sent in clear text to authenticate requests.
SNMPv2c relies on community strings (e.g., 'public', 'private') transmitted without encryption, making it less secure.
- C
SNMPv3 provides the same security level as SNMPv2c but with additional trap support.
Why wrong: SNMPv3 is more secure than SNMPv2c; both support traps, but SNMPv3 adds authentication and encryption.
- D
SNMPv2c supports only GET and SET operations, but not traps.
Why wrong: SNMPv2c supports GET, SET, and trap operations, similar to other SNMP versions.
- E
SNMPv3 uses community strings to authenticate agents and managers.
Why wrong: SNMPv3 uses user-based security model (USM) with usernames and authentication keys, not community strings.
Quick Answer
The correct answer identifies SNMPv2c as using community strings sent in clear text and SNMPv3 as introducing authentication and encryption for secure monitoring. SNMPv2c relies on plaintext community strings—essentially passwords—that are transmitted without any protection, making them vulnerable to interception, while SNMPv3 adds robust security through MD5 or SHA for authentication and DES or AES for encryption, ensuring data integrity and confidentiality. On the CCNA 200-301 v2 exam, this distinction tests your understanding of network monitoring security fundamentals, often appearing in questions that contrast legacy and modern protocols; a common trap is assuming SNMPv3 still uses community strings, but it replaces them with usernames and security models. Remember the mnemonic: “v2c is clear, v3 is secure”—if you see community strings, think v2c; if you see encryption, think v3.

Answer choices
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
SNMPv3 supports authentication and encryption for secure network monitoring.
SNMPv3 is correct because it introduces authentication (MD5/SHA) and encryption (DES/AES) for secure monitoring. SNMPv2c is correct because it uses community strings transmitted in cleartext, lacking security. Option C is wrong: SNMPv3 is more secure than v2c, not the same. Option D is wrong: SNMPv2c supports traps in addition to GET and SET. Option E is wrong: SNMPv3 uses usernames and security models, not community strings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓SNMPv3 supports authentication and encryption for secure network monitoring.Correct answer▾
Why this is correct
SNMPv3 includes security features such as authentication (MD5/SHA) and encryption (DES/AES) to protect data in transit.
✗SNMPv3 provides the same security level as SNMPv2c but with additional trap support.Wrong answer — click to see why▾
Why this is wrong here
SNMPv3 provides significantly higher security than SNMPv2c by adding authentication and encryption, whereas SNMPv2c uses only community strings in clear text. Both versions support traps, so the statement incorrectly claims SNMPv3 has additional trap support, which is not a distinguishing feature.
Why candidates choose this
Students may confuse the enhanced security features of SNMPv3 with additional trap functionality, or they might think that SNMPv3 is just a more secure version of SNMPv2c with the same features plus traps, but traps are present in both.
✗SNMPv2c supports only GET and SET operations, but not traps.Wrong answer — click to see why▾
Why this is wrong here
SNMPv2c supports GET, SET, and trap operations, just like SNMPv1 and SNMPv3. The statement is incorrect because it claims SNMPv2c does not support traps, which is false; traps are a key feature for asynchronous notifications in network monitoring.
Why candidates choose this
Test-takers might confuse SNMPv2c with an earlier or limited version, or they may think that traps were only introduced in SNMPv3. However, traps have been part of SNMP since SNMPv1.
✗SNMPv3 uses community strings to authenticate agents and managers.Wrong answer — click to see why▾
Why this is wrong here
SNMPv3 uses the User-based Security Model (USM) with usernames and authentication keys, not community strings. Community strings are a feature of SNMPv1 and SNMPv2c, which are transmitted in clear text and provide weak security.
Why candidates choose this
Students familiar with SNMPv2c may assume that community strings are used across all versions, but SNMPv3 replaced them with a more robust user-based authentication model. The term 'community' might be mistakenly associated with SNMPv3.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that SNMPv3 is merely an extension of SNMPv2c with added trap support, when in fact the key differentiator is the security model (authentication and encryption), and both versions support traps.
Trap categories for this question
Similar concept trap
SNMPv2c supports GET, SET, and trap operations, similar to other SNMP versions.
Detailed technical explanation
How to think about this question
SNMPv3 defines three security models: noAuthNoPriv (no authentication or encryption), authNoPriv (authentication only), and authPriv (both authentication and encryption). The encryption in SNMPv3 uses the CBC-DES (RFC 3414) or newer AES (RFC 3826) algorithms, while authentication uses HMAC-MD5-96 or HMAC-SHA-96. In contrast, SNMPv2c relies on community strings (e.g., 'public' or 'private') transmitted in plaintext, which can be easily intercepted via packet capture tools like Wireshark, making it unsuitable for production networks requiring security.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 practitioner preparing for the 200-301 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
