300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show snmp host
Host: 192.168.1.100 Port: 162 Timeout: 1.5 seconds Retries: 3 Version: 2c Community: PUBLIC
Host: 192.168.1.200 Port: 162 Timeout: 3 seconds Retries: 5 Version: 3 User: admin Security level: authPriv
Based on this output, which statement is correct?
⚠ Common exam trap
Cisco often tests the distinction between SNMPv2c community strings and SNMPv3 users/security levels, leading candidates to mistakenly associate a community string or user with the wrong host or version.
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
✓
SNMP traps sent to 192.168.1.200 will be encrypted.
The SNMPv3 security level 'authPriv' for the host at 192.168.1.200 means authentication and privacy (encryption) are both enabled. SNMPv3 with authPriv uses the User-based Security Model (USM) to encrypt the entire SNMP packet payload, including the trap data, using protocols like AES or DES. This ensures that traps sent to 192.168.1.200 are encrypted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
SNMP traps sent to 192.168.1.200 will be encrypted.
Why this is correct
The security level 'authPriv' requires both authentication and privacy (encryption).
- ✗
Both hosts use the same SNMP version.
Why it's wrong here
One uses version 2c, the other version 3.
- ✗
The host at 192.168.1.100 uses SNMPv3 with user 'admin'.
Why it's wrong here
192.168.1.100 uses version 2c with community 'PUBLIC'.
- ✗
Traps to 192.168.1.200 will be sent with community string 'admin'.
Why it's wrong here
SNMPv3 uses users and security levels, not community strings.

| Algorithm | Key Size | Block Size | Status | Notes |
|---|---|---|---|---|
| AES-128 | 128-bit | 128-bit | Current standard | NIST approved; WPA3, TLS |
| AES-256 | 256-bit | 128-bit | Current standard | Preferred for sensitive / govt data |
| 3DES | 112-bit effective | 64-bit | Deprecated (2023) | Replaced by AES |
| DES | 56-bit | 64-bit | Broken | Cracked in < 24 h; never deploy |
| ChaCha20 | 256-bit | Stream cipher | Current | TLS 1.3, WireGuard |
