300-410 Practice Question: The default SNMPv3 security level for a user…
What is the default SNMPv3 security level for a user configured with the "snmp-server user username groupname v3 auth sha password" command?
⚠ Common exam trap
It's easy for candidates to assume the command is invalid or that the security level must be explicitly stated, but Cisco's CLI defaults to `authNoPriv` when only authentication is configured, and the command is perfectly valid without the `priv` keyword.

Correct answer & explanation
✓
authNoPriv
When you configure an SNMPv3 user with the `snmp-server user username groupname v3 auth sha password` command without explicitly specifying a privacy (encryption) password or the `priv` keyword, the default security level is `authNoPriv`. This means authentication is enabled using SHA, but no encryption is applied to the SNMP packets. The security level is implicitly set to `authNoPriv` because the command includes an authentication password but omits the privacy password.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
noAuthNoPriv
Why it's wrong here
This level requires no authentication and no privacy; the command includes auth, so this is incorrect.
- ✓
authNoPriv
Why this is correct
When only auth is configured without priv, the default security level is authNoPriv per RFC 3414.
- ✗
authPriv
Why it's wrong here
authPriv requires both authentication and privacy; privacy is not configured here.
- ✗
The command is invalid without specifying a security level.
Why it's wrong here
The command is valid; the security level defaults to authNoPriv when only auth is specified.
