300-410 Practice Question: Runs the following command to troubleshoot…
A network engineer runs the following command to troubleshoot SNMPv3:
R1# show snmp user
User name: admin Engine ID: 800000090300001122334455 Storage-type: nonvolatile Authentication Protocol: SHA Privacy Protocol: AES128 Group: admin-group
User name: monitor Engine ID: 800000090300001122334455 Storage-type: nonvolatile Authentication Protocol: MD5 Privacy Protocol: DES Group: monitor-group
What does this output indicate?
⚠ Common exam trap
Cisco often tests the ability to read the 'show snmp user' output carefully, where candidates may overlook the different groups or security protocols and assume all users share the same settings.
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
✓
Two SNMPv3 users are configured: 'admin' with SHA/AES128 and 'monitor' with MD5/DES.
The output from 'show snmp user' displays two SNMPv3 users: 'admin' with SHA authentication and AES128 privacy, and 'monitor' with MD5 authentication and DES privacy. This confirms that both users are configured with different security levels, making option A correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Two SNMPv3 users are configured: 'admin' with SHA/AES128 and 'monitor' with MD5/DES.
Why this is correct
The output shows the authentication and privacy protocols for each user.
- ✗
SNMPv3 is not configured because no users are shown.
Why it's wrong here
Two users are shown, so SNMPv3 is configured.
- ✗
Both users use the same authentication and privacy protocols.
Why it's wrong here
Admin uses SHA/AES128, monitor uses MD5/DES.
- ✗
The users are in the same SNMP group.
Why it's wrong here
Admin is in 'admin-group', monitor is in 'monitor-group'.
