300-410 Practice Question: Which TWO statements correctly describe the…
Which TWO statements correctly describe the behavior of SNMPv3 when using the 'noAuthNoPriv' security level? (Choose TWO.)
⚠ Common exam trap
Cisco often tests the misconception that 'noAuthNoPriv' sends a password in clear text, when in fact no authentication is performed at all, so no password is transmitted.
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
✓
The SNMP engine ID is still used for message processing and identification.
SNMPv3 always uses the engine ID for message processing and identification, regardless of the security level. Even with 'noAuthNoPriv', the engine ID is included in the SNMP message to uniquely identify the SNMP engine, enabling proper message handling and context for the security model.
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 username and password are sent in clear text.
Why it's wrong here
In 'noAuthNoPriv', no authentication password is used; only the username is sent. There is no password involved.
- ✓
The SNMP engine ID is still used for message processing and identification.
Why this is correct
The engine ID is always used in SNMPv3 for message processing, regardless of the security level.
- ✗
The 'snmp-server user' command must include the 'auth' and 'priv' keywords set to 'md5' and 'des' respectively.
Why it's wrong here
For 'noAuthNoPriv', the 'auth' and 'priv' keywords are omitted. Including them would require authentication or encryption.
- ✗
The security level is configured per user, not per group.
Why it's wrong here
The security level is configured per group via the 'snmp-server group' command; the user inherits the security level from the group.
- ✓
The engine ID can be manually configured or automatically generated based on the router's MAC address.
Why this is correct
The engine ID is either generated automatically (using the router's MAC address) or manually set with the 'snmp-server engine-id' command.
